See Why Kirby Vacuums Rock – The History Of The Kirby Vacuum Cleaner

Jim Kirby started Kirby vacuum cleaners. He was an inventor who had over 200 patents to his name. In 1906 he made his first cleaning machine. In 1925 he made the Vacuette Electric that had a removable nozzle and was the first upright vacuum cleaner that you could remove the tools from. In 1970 his company made the first Kirby Classic. This was to become a design classic and the resulting sales meant that the factory had to double it’s output. In 1990 they redesigned again this time bringing about some new innovations. The Generation 3 Model has a lightweight aluminum design and a power assisted motor that actually does most of the work of moving the cleaner around for you.

It also has a very advanced powerful filtration system that can remove nearly all the dirt and dust from the air that it filters. This can be very important for consumers that suffer from hay fever and asthma. It is also important for allergy sufferers who are affected by such things as dust mites. The power unit has a very good design team as NASA assisted the team from Kirby vacuum cleaners in designing it. Most of the latest design is the product of their new computerized design system, but Kirby vacuum cleaners still like to give all of there products that personal aspect and some of their operations are still carried out by people rather that being fully automated.

Another aspect where Kirby vacuum cleaners like to keep it personal is in their sales. They still prefer to use the old fashioned method of showing the product to the customer in their own home. They think that this gives them more of a connection, not only with the customer, but also with what the customer wants. It also gives a good incentive to their sales team as they are effectively running their own business. This gives then even more encouragement to look after the customer and to make sure that they get what they want.

All of this adds up to the fact that Kirby vacuum cleaners are a customer led company and they base their products and sales on giving the customer the best deal on the products that they want. Although Kirby has gone through many different transitions as a company their focus has always remained the same and it has given them a loyal customer base and a strong market share.

The Significance of Pure Air Inside Your Home

Have you ever climbed up mountains? If so, what do you do when you reach the top? Most people open their arms, close their eyes, and take a deep breath. That is the special thing about clean and fresh air. You feel like taking a pause and inhaling fresh air. Over the past year, we have faced several waves of coronavirus. These days, we have been warned about another wave of this virus. Therefore, the importance of clean air has been increasing day by day. In this article, we are going to find out why air quality is important when it comes to our indoor environment.

The impact of pollution on your indoor air

No matter where you go, you will have to face the consequences of poor quality. Even if you are alone in your home, you will still be prone to polluted air. Every year, more than 1 million people lose their life because of air pollution.

According to some reports, India is among the top 10 countries in the world with the worst air quality. The effect of polluted air is more evident as people spend over 90% of their time inside their homes. Another research study found that residents are at a greater risk of covid-19.

As a matter of fact, indoor air pollution has become an international concern. We can say that pollution levels inside and in closed spaces are up to five times higher. Since most pollutants are not visible to the naked eye, you may not be able to aware of the dangers of dirty air.

Indoor air pollutants may be generated by common household items, such as cleaning agents, cooking fuel, furniture polish, pet dander, and paint. Apart from this, domestic appliances such as refrigerators and heaters may also be the common source.

Since homes are not airtight, air pollutants can easily get in. For example, smog, smoke, mold spores, and dust can get into your house through your windows or doors. Air conditioners can be used to cool down your rooms. But the downside is that they can also boost the movement of pollutants across your house.

What can you do to purify your indoor air?

Basically, air purifiers are simple devices that receive dirty air and put it out after passing it through powerful filters. Nowadays, you can choose from hundreds of air purification units available in the market. They are based on a wide range of technologies. They are available in different sizes to cover rooms of different sizes.

Nowadays, most types of air purifiers depend on HEPA technology. Initially, this technology was introduced in the 40s in order to capture pollutants from the air. Although these filters have been used for the filtration of particulate matter, they may not be that effective when it comes to eliminating volatile organic compounds.

Therefore, if you are worried about your health, we suggest that you invest in a type of device that comes with a HEPA filter. With these units, filtering your indoor air will be a piece of cake. Therefore, you can count on these devices to and ensure clean air inside your house.

Refrigerator’s Air Circulation and Humidity

The refrigerator relies on forced air to transfer heat. Fans inside the appliance move air around. The faster the air flows, the more quickly the heat is removed. For this reason, you don’t want to do anything to block the airflow. There are three basic types of forced-air systems in refrigerators. In ceiling-type refrigeration,

a single fan is mounted on the ceiling of the appliance. This is adequate for small-volume interiors but is not used in larger refrigerators. Because it only has a single location, it might allow for hot spots in the corners of the interior cabinet. In back-wall or mullion-type refrigeration, the airflow system takes in air above the top shelf and discharges it below the bottom shelf.

The duct-type refrigeration system is a combination of the first two types. Here, the forced-air unit is located at or above ceiling level, and the air is circulated through a series of small air ducts vented to various spots on the back wall of the cabinet. Just how important is air circulation? Well, the difference between safe and unsafe raw foods can be as little as five to seven degrees Fahrenheit. Seafood, poultry, or red meats will spoil within 18 to 24 hours if their refrigerated temperature rises above 42 to 45 degrees

Fahrenheit, and you already know the HACCP guideline of temperatures no higher than 40 degrees Fahrenheit. Would you rather risk a lawsuit and the resulting negative publicity from food-poisoning allegations, or keep your refrigerator air circulating properly?

Humidity is the amount of moisture (or water vapor) in the air. At different temperatures, air can hold different amounts of water. In refrigeration, the type of humidity we are interested in is the relative humidity, or how much of its maximum water-holding capacity the air contains at any given time, expressed as a percentage. For example, 85 percent humidity indicates that the air is holding 85 percent as much water as it could hold at that temperature. Relative humidity greatly affects the appearance and rate of deterioration of many foods. If the air surrounding the stored foods has a very low relative humidity, for instance, the air naturally picks up moisture from the foods themselves, causing surface discoloration, cracking, and drying.

If the air has a high relative humidity, some of the moisture will condense on food that is supposed to be kept dry, causing it to soften or grow mold or bacteria. Fortunately, most foods do well in a relative humidity of 80 to 85 percent. To achieve this optimum level, manufacturers are concerned that the refrigerator’s evaporator coils be large enough to operate at a temperature a few degrees lower than the desired temperature of the appliance. This differential reduces the amount of moisture that accumulates on the evaporator coils and keeps the moisture in the cabinet of the refrigerator instead. If the coils’ temperature becomes too low, however, the moisture will turn to ice crystals and get stuck on

the coils.

In this case, airflow through the system is blocked and the moisture in the refrigerated space is depleted. As you can see, getting all the factors right is a delicate balance, with your food costs and food quality at stake. In short, it is difficult to keep frost off the coils but necessary to keep them frost-free so they will operate properly. Adding heat to the area, to defrost the coils, can compromise the temperature of the food inside. A fairly new concept from Hussman Modular Defrost of Bridgeton, Missouri, does just what its name indicates: defrosts the coil in sections. The automated system defrosts coils at no more than nine minutes per section, and never defrosts adjacent sections at the same time, all programmed by an electronic controller capable of running up to six walk-ins.

The idea works for walk-in and reach-in refrigerators but not freezers. It maintains food quality and saves energy by keeping the compressors from working overtime to compensate for frozen coils. Another humidity-control suggestion for inside refrigerated space was pioneered by Humitech International Group, Inc. of Dallas, Texas. Humitech uses a mineral product called sorbite to absorb moisture and odors.

We mentioned most foods do well at 80 to 85 percent relative humidity, but fresh fruits and vegetables are exceptions. They require more humidity, up to 95 percent. To increase moisture content, you can slow down the air circulation. This explains why there are separate, closed produce bins in most refrigerators-to hold in natural moisture from the vegetables and to restrict airflow.

Freezers maintain an average relative humidity of only 30 to 35 percent. Any more moisture would automatically raise the temperature because it would hit the coils, freeze in place, and block the airflow, causing the freezer air to become warmer. The low humidity of freezers requires special food storage precautions. Use moisture- and vapor-proof wrapping to prevent the surface damage we know as “freezer burn” from occurring if any moisture condenses on the food.

What Can Far Infrared Water Filtration Systems Do For You?

With the ability to clean the water and enhance its structure, far infrared water filtration (FIR) has some consumers wondering if this may be the blessing in disguise they’ve been waiting for. With our body being made up of over 70% water, simply removing contaminants isn’t good enough anymore, considering the level of today’s knowledge and technology. Far infrared water filters claim to provide consumers with the opportunity to deliver clean water that is refreshing crisp and energized to boot.

Far infrared rays are the invisible portion of the sunlight spectrum that has been found to promote growth and health to living cells in plants, animals, and humans. By using a far infrared water filtration system, some have estimated an enrichment of treated water that somehow strengthens various organs within our bodies.

It is vital that all drinking water filters detect and decontaminate any sort of impurities that may be found in our water. However, above and beyond this standard requirement, some also crave the ability to enhance the water’s structure and properties. By doing so, far infrared water filtration may allow us to drink energized water while getting superior hydration; all in the name of improving overall health.

So how does it work you may ask? Far infrared rays are reported to have the ability to penetrate the human body in order to activate cells. With continuous movement, the rays are alleged to reactivate cells to help strengthen the micro-circulatory system. The micro-circulatory system is often the cause of various ailments. By strengthening this system, some may reduce or even reverse ailments that have plagued their bodies for years.

There are several effects far infrared rays can have on our body, all of which can have a strong positive effect when used as a far infrared water filter. Theoretically, the water filter will soften hard water, eliminate offensive odors, and destroy any potentially harmful contaminants. FIR could also be shown to prevent bacterial growth, be used to purify the air, or prevent mould from occurring. As far as our health goes, FIR may also regulate the blood flow, increase resistance against various diseases and balance the acidity levels in our bodies.

While empirical evidence to back up this technology is sketchy at best, many people swear by far infrared water filters. Not only do these types of filters claim to be able to eliminate harmful contaminants and bacteria, but they also claim to enhance your health and even slow down the again process. Another claimed benefit is that through the warming and eliminating of fats and chemicals in your body, this technology is able to reduce or even eliminate certain types of circulatory problems. With these kinds of benefits being touted, it is no wonder that consumers are taking advantage of the far infrared water filtration system. The real question is; will FIR filtration systems work for you?

A Clean Bird Room – 5 Ways To Keep Your Aviary Clean

A clean environment for your bird will keep you and your pet healthier. Sometimes it may feel like effective cleaning is easier talked about than done. But following the 5 suggestions below will help you drastically reduce the number of particles in your bird room.

Avoid Particle Traps—-There are so many places in the usual home and even bird room that can trap allergens. Wall-to-wall carpet, upholstered furnishings, piles of books and magazines, fabric draperies, horizontal blinds, and the list goes on and on.

Most of these surfaces are woven and can trap an unbelievable number of particles that can and are sent airborne with daily activities. The more of these you can eliminate, the better you will be able to clean thoroughly and really reduce the number of particles that are even available to get into your air.

As you add to and replace furnishings in your bird room and home, think bird-friendly replacements. Opt for easy-to-launder throw rugs that are easy to launder. Consider furniture that can be wiped down with a damp cloth rather than fabric covered pieces.

Choose linoleum, tile, wood, or other hard surface that can be mopped clean. And think about shades that can be rolled up and wiped clean and vertical blinds as options that will allow more particles to fall to the floor.

Say No—Saying no to just one more bird can mean that the bird(s) you have already adopted will have a better life. If you are a bird-lover you probably want to give every homeless bird a good life. But depending on the size of your space, continuing to add birds past a certain point makes it nearly impossible to keep conditions healthy.

"The more the merrier" rule does not apply in this situation. Offering fewer birds a good life trumps having a ton of birds that you are unable to care for properly.

Clean Often—How often you clean will be your call based on your situation. But you’ll be able to tell if your schedule is working pretty quickly. Some people are able to clean every couple of days, and others feel they need to clean every day and sometimes more than once a day.

Your frequency will depend on the number and type of birds you have. Those with powder-down birds such as African Greys, Cockatoos, or Cockatiels may find that more frequent cleaning is necessary to keep up with the incessant white powder that these parrots produce.

The goal is to literally keep the dander and dust down. Your room doesn’t need to be able to be able to pass the white glove test, but almost.

Clean Smarter—One of the best ways to really take particles out of circulation is to use water to clean. Adding water to the mix with a damp mop or cloth makes the particulates too heavy to escape into the air again and gives you more of a chance of permanently eliminating them.

A vacuum with a HEPA or high efficiency particle arresting filter is also an excellent way to make sure that what is sucked into the vacuum cleaner stays in the vacuum cleaner. Keep the broom and dust mop out of the mix and opt for the vacuum cleaner.

Filter The Air—Regardless of how smart or frequently you clean, particles will get into the air. Particles just come with the territory when you live with birds. The only way to reliably keep the air clean is to filter it continuously.

HEPA filtration is best because its only by-product is fresh air. There are no ionized particles or ozone levels to worry about.

HEPA filtration is used by hospitals and will surely work for you in your situation. This type of filter must have proven that it is able to eliminate 99.97% of airborne particulates that are.3 microns or greater.

Together, these 5 steps can take you closer to providing a wonderful life for you avian friends, and a healthier life for all who live with them.

Water Vacuum Cleaners – Advantages And Disadvantages

Water vacuum cleaners are by far the most revolutionary and most efficient type of all vacuum cleaning units. With a filtering efficiency rate of 100%, this home cleaning appliance puts to shame the vacuum cleaners made before it. But no matter how expensive and high-tech some water vacuum units are, like everything, it still has its strong points and faults.

The water vacuum cleaner uses water pressure to effectively filter the floor, furniture, air and other parts of the house as well. It not only removes bacteria, viruses and other pathogens in our homes, it cleanses the air of bad odor as well. Water vacuum cleaners have been proven to help people with allergy problems a great deal by eliminating allergens where they live in the household.

Many water vacuum cleaners come with other amazing add-ons. Some has air treatments including aromatizing, humidifying and dehumidifying features. Steam cleaning and stain washing in furniture and hardwood floors are common attributes of such vacuums. They are versatile and can clean just about any surface. All these it can do while using a considerably low amount of energy.

However, experts argue over how effective water vacuum cleaners really are. One fault of these type of vacuum cleaners is that the water it uses must be constantly replaced. Because the filtering of dust mainly relies on water pressure, the water occasionally gets filthy and thus the system starts to work ineffectively. A series of studies have shown that opening the filter compartment while replacing water allows some of the bacteria accumulated to be scattered in the air again. This shatters the whole point of the 100% filtering efficiency rate. Some has also suggested that HEPA filters are more successful in cleansing the air.

The need for clean water also appears to be impractical, since most water cleaners operate on large amounts of purified water. This is rather costly and unreasonable, especially for home use. These water units are also big, heavy and bulky so in result it needs a large storage compartment. It is not ideal for use in small homes, and cannot effectively work in small areas. Because they are heavy, only the adults can operate the vacuum with ease.

Lastly, the vacuum cleaner is expensive itself. Unlike air vacuum units, they usually come at about 200 to 350 dollars. High-tech models can cost as high as $2500. This makes it over the top for most American families. In effect, water cleansing units are suitable only for large facilities and institutions that safeguard cleanliness, such as hospitals and quarantine centers.

All in all, the choice to avail water vacuum cleaners is really up to one’s taste and lifestyle. If you are considering getting one for your household, just make sure that you get your model from a trusted brand.

Essential Tools Necessary for Professional Carpet Cleaning

Carpet is an integral part of floor decor, uplifting the visual appeal of the space with its sleek texture. However, these carpets are prone to wear and tear due to daily foot traffic, dirt, dust mites and occasional spills. To ensure a clean and well-maintained carpet, periodic carpet cleaning using the right tools and equipment is of paramount importance. Cleaning with the standard home cleaning supplies simply does not produce the desired result.

Here are the five most widely used equipment used by professionals for a thorough carpet cleaning.

Portable Cleaning Tools

For smaller areas, carpet cleaning experts use portable equipment, which are relatively large machines but is easy to carry. These machines are available in various types depending on the purposes of their uses. The portable equipment is designed for various methods of carpet cleaning based on the kind of carpet and the customer’s preference like carpet shampooing, bonnet cleaning, encapsulation, hot water extraction or dry carpet cleaning. Professional companies carry most of these portable tools with them to perform cleaning, adopting various approaches with the machines for the different methods.

Some other portable types of equipment that professional services use are as follows:

Vacuum Cleaner: A vacuum cleaner is an essential carpet cleaning tool to tidy up the carpets and complete the cleaning procedure.

Defoamer: Foam can reduce the effectiveness of the cleaning process. Hence carpet cleaners use defoamer to remove the foam and speed up the drying process. These defoamers are a mixture of silicone or oils that are effective in removing the foam.

Air Scrubber: This device works as an air filtration system and is used during dry cleaning to get rid of airborne particulates, fungi, and foul odours from the carpet. The scrubber is used after a deep cleaning job to increase the air quality in the room.

Carpet Cleaning Wand: This is the primary tool in the cleaning process. The wand is used to spray the cleaning solution as water jets, which is then sucked back through the vacuum slot in the equipment. While rotary cleaners work best for shaggy carpets, wool carpets are best cleaned with wands to prevent any kind of damage to the carpet fibres. It is not possible to use a pro extractor without one.

Crevice Tools:These are special tools to clean crevices like those between the stairs, areas that are difficult to reach and upholstery cleaning.

Protective Tools: To protect furniture and other items from suffering any kind of damage while cleaning, professionals use these protective accessories like furniture protectors, caution signs, straps, corner guards, and chemical racks.

Ventilation Assister: On completion of wet cleaning methods, service providers may blow fans to expedite the drying of the carpet.

Truck-Mounted Cleaning Equipment

These are heavy-duty cleaners suitable for cleaning larger spaces. However, it must not be inferred that truck-mounted cleaners are only used for larger commercial workspaces. There are many homes that opt for them due to certain advantages like these powerful cleaners do not mess the area cleaned since the machines draw water out of the building as the cleaning process continues instead of draining them into the toilet or sink.

These are some of the vital equipment necessary for deep cleaning of the carpet. It needs mentioning that the use of tools depends on the nature of the carpet and the type of cleaning service chosen. Before hiring the services of professional cleaners, it makes sense to find out the kind of carpet cleaning your want and if the service provider has the right tools and equipment to perform the job successfully.

3 Signs It Might Be Time to Install a Water Filter

When water tastes bad and clothes are dingy, these may indicate that a home needs a filtration system. The following are the other signs to inspect alongside suggestions for water filters that can address the unfavorable effects caused by impurities.

Most homeowners believe that the water from their faucet is clean and safe however, this is not always the case. The truth is, tap water usually contains impurities even if it looks and tastes good. There are impurities that are harmless but others are dangerous and ruin water using appliances and fixtures.

Filtration requirements differ from one home to another, which depend on the type of contaminant present in the water and the way household members consume water. When the water is pure and there are only few fixtures utilized for human consumption, the affordable under-sink carbon filters would be an ideal choice. If the water has toxins or a high level of minerals, the house will be needing a filtration system, which is designed to treat water all through the house.

To know the water filtration needs of a household, they can review the scenarios that follow. If ever one of these looks similar to their water situation, both household and members could benefit from water filtration. Before purchasing a filtration system, a local provider should conduct a professional water test first.

Water tastes bad

Municipal water systems often do great in eliminating harmful toxins from tap water; however, in spite of their efforts, water in other communities does not taste good. There are certain areas in the country that tackle issues on taste, such as hard water. While water is healthy to drink, when it has high mineral content or has been chlorinated, it can have a bad taste.

One common reason why homeowners spend for a water filtration system is bad-tasting water.

Well water is their source

There are a number of private wells that give clean, healthy water. However, in the past decades, the extensive use of pesticides plus other chemicals has contaminated such wells in several states and regular carbon filters are not capable of removing the more dangerous toxins that may be in the water. Carbon filters can only be used for lighter-duty filtration of things such as lead and chlorine but to ensure elimination of heavy metals, nitrates and pesticides, a reverse osmosis (RO) system is required.

Clothes look dingy after washing

No matter what kind of detergent is used, it is almost impossible to let white clothes become whiter or colored clothes become brighter. Actually, the problem is not the washer or detergent but the composition of water that was used. Water that has high iron content can leave a rust looking stain in colored clothes and hard water can make clothes look dull and gray.

When newly washed clothes regularly show any of these two shades, an under-sink filter will not be sufficient. This will require a whole-house water treatment system in order to remove contaminants like iron, minerals and sediments, among others, that make clothes look dingy. This filter is installed on the main water supply pipe through which it enters the home. Since it filters the water in the whole household, aside from having cleaner, brighter clothes, people will enjoy drinking water that is tastier.

3 Lies About Drinking Water Filtration and the Truth Behind the Lies

The drinking water filtration market is big. Companies make a lot of money selling home water filters, and then they make even more money after that by selling replacement filter cartridges to their customers who bought their purifiers. And as we all know, whenever and wherever there is money to be made, there will be plenty of lies told. Here are 3 lies that are frequently spouted by salesmen trying to get you to buy the water filters made or sold by their companies.

The 1st Big Fat Lie

Drinking water filtration using carbon technologies and reverse osmosis technologies are only good at removing dirt and chlorine. They do not protect you from bacteria, amoeba, protozoa and other microbes.

Who tells this lie: Usually it is the salesman selling purifiers that have an attached UV lamp.

What is the truth? All developed nations and even many 3rd World nations use chlorination to kill germs. Every microorganism except for the cysts of certain protozoa die from normal municipal treatment. Any reverse osmosis filter will remove these cysts from your water supply. And any carbon water purifier rated for 1 micron or smaller will also remove these cysts. UV light only deactivates the genes of these cysts so that they cannot reproduce. They cannot kill these cysts.

The 2nd Big Fat Lie

Don’t worry, be happy. It is very easy to change your filter cartridge. Just make sure to change it twice a year.

Who tells this lie: Any and all salesmen whenever you ask about the cost and frequency replacing the filter. Some of them may also tell this lie when you ask them for a demonstration.

What is the truth? Changing the cartridge every 6 months is only a recommendation from the manufacturer. Many people who buy home water filters actually have water supplies that are much more dirty than average. They will probably need to change their filters more often than the recommendation of every 6 months. They may need replacements as often as 3 times a year, maybe even 4 times a year. Replacing the purifier cartridge is also not that easy. Most of the better brands have more complicated working parts inside, which require more complex procedures to make sure everything works at peak performance.

The 3rd Big Fat Lie

Water filter jugs are the least effective means of home water purification. They only remove chlorine and lead but let other chemicals and cysts pass through.

Who tells this lie: Any salesman who does not sell PUR or Brita pitchers, whenever you wonder if buying a water filter pitcher may be a smaller and more affordable commitment.

What is the truth? Just like any other type of filtration, manufacturers make different models of pitchers with different levels of purification. Just like high-end home filtration systems from any other brand, high-end PUR and Brita pitchers can remove not only chlorine and lead but also cysts, herbicides, pesticides, nitrites and nitrates. Of course, that means you need to buy the high-end model rather than the cheap model.

Selling drinking water filtration devices is big money, and this leads many salesmen to be less than truthful, especially when talking about their competitors’ products. Now that you know three of the major lies they tell, it should be easier for you to make a good decision.
