Air purifiers have been around in various forms since the 1940s, when the first HEPA filter was designed to protect workers from airborne nuclear material. Since then, air purifiers have been used in hospitals, work sites, and homes to protect against viruses, mold, bacteria, pollen, pet dander, tobacco smoke, dust mites, and a great number of industrial and household chemicals. The people who stand the most to gain from air purifiers are those with allergies, asthma, and other respiratory ailments.
But everybody can benefit from having cleaner air in the home. The Environmental Protection Agency lists indoor air pollution among the top five environmental risks to public health. In fact, the inside of your home could well contain two to one hundred times more air pollutants than an outdoor urban environment.
Air purifier value varies widely. You can spend upwards of $1600 for the best air purifiers known to man, or you can spend as little as $70 for a good car unit. You can also spend an arm and a leg on junk if you're not careful. One thing to keep in mind when buying an air purifier is unit-to-filter value. If your unit uses a HEPA filter, find out how much it costs to replace the filter. You may end up spending thousands on the filter alone. The question is, what kind of a machine do you want?
Home air purifiers use a number of technological approaches to cleaning your air so you can breathe more easily. They use HEPA (High Efficiency Particulate Air) filters; electrostatic filters, ion generators, ozone generators, ultraviolet light, and other methods to get rid of both large and miniscule particles. Some operate by drawing in air via a fan, cleaning the air, and re-releasing it. Others work by actually sending out "purifying agents" throughout the room.
Today you have two basic choices for home air purifiers: room air purifiers, and whole house purifiers. Generally speaking, room purifiers are better for air-cleaning efficiency and cost.

The Benefits of HEPA Air Purifiers The military designed the first HEPA filter in the 1940s for use in the Manhattan Project, when safety from free-floating nuclear material was a primary concern. Today, HEPA air purifiers are very widely used to remove dust, pollen, mold, bacteria, and other airborne particles.
The Benefits of Ozone Air Purifiers Ozone air purifiers or "ozone generators" are known for their effectiveness at reducing and masking the smells of new carpet and acrolein, a chemical partly responsible for the noxious odor of second-hand tobacco smoke. There are two types of ozone generators.
Which Air Purifier is Best For You? Perhaps the best air purifiers are those from the IQAir line. These units are widely used in hospitals to eliminate mold, viruses, and bacteria. In fact, the Hong Kong Hospital Authority chose the IQAir Health Pro as the only acceptable air purifier during the SARS outbreak.
The Benefits of Owning an Ionic Air Purifier Ionic air purifiers are not filter systems. Ionic air purifiers work by sending out negatively charged ions into the air of your home. The ions latch onto chemicals and particles such as dust, tobacco smoke, and pollen, causing them to become attracted to each other and to the interior surfaces of your home.
Types of Home Air Purifiers There are several types of air purifiers that you can use to improve the quality of the air in your home, from smaller units that can be placed on a tabletop, to whole house air purifiers that benefit the entire house at once.
