Air Purifier-The Need Of The Day

Air purifier is the most useful appliance in todays home. Most people assume that outdoor air has more pollution than indoor air does. But these people are wrong. It is estimated by the Environmental Protection Agency (EPA) that air is up to five times more polluted in an indoor environment than in an outdoor environment. The reason for this is because people seal their homes tightly in order to make them more energy efficient. Although this will help them save money on their electric bills, it will also trap animal dander, cigarette smoke, dust, mold, and chemicals from cleaners inside of their homes. Long-term exposure to these contaminants can aggravate the symptoms of allergies and asthma.

The purpose of an air purifier is to eliminate the contaminants in the air. An air purifier can even eliminate airborne contaminants that are smaller than a grain of sand or dust mite. There are many different air purifier models to choose from. Each different air purifier is designed to eliminate a certain type of contaminant.

The most effective air purifier is the one that uses the HEPA (High Efficiency Particulate Air) filter. The HEPA filter was invented during the 1940s because the United States Atomic Energy Commission wanted something that could remove small radioactive particles. A HEPA air purifier is designed to remove at least 99.97 percent of all particles that are 0.3 microns or larger in diameter. Today, there are many HEPA air purifiers that are used to clean the inside of places such as a clean room or beauty parlor. There are many doctors that will recommend the use of an HEPA air purifier to alleviate the symptoms of asthma or an allergy.

The HEPA filter has an inlet grill that draws in contaminated air. It has a washable pre-filter that traps larger particles. The filter will trap allergens such as animal dander, mold, dust, and pollen. There are also many HEPA air purifiers that have a carbon filter. A carbon filter is effective in trapping gases, odors, and chemicals. Then, after the unit is finished purifying the contaminated air, a fan will send the clean air back into the room.

An air purifier will not eliminate the contaminants from your entire home. You should put one in places where you will spend a lot of your time. The bedroom may be a good place to your put an air purifier since studies indicate that people spend about thirty three percent of their lives in their bedrooms. Also, you might consider putting an air purifier in a room where your pets stay most of the time if you happen to have an allergic reaction to animal dander. In order to maximize the air flow in any room, you should leave your air purifier on at all times and make sure that it is at least several feet from the walls. Fortunately, leaving a unit on at all times will not cause a significant increase to your electricity cost. For the rooms that do not have an air cleaner, at the very least, you should make sure that they are well ventilated.
