Almost like sweeping a magnet through the air, these air purifiers attract, collect and contain all kinds of pollutants such as tobacco smoke, allergens, dust mites and dust mite feces, pet dander, mold and much more.

Microscopic particles by the millions are able to be collected and removed from the indoor atmosphere as the air passes through the home air purifier.

At that time, when the air passes through the device, the largest particles are caught in the screen of the pre-filter and the smaller particles then move on to the next section where they receive an electrical charge by ionization.

Once these tiny particles are charged, they then pass on to the collection unit where they are attracted electronically to a series of charged collector plates. The particulates are essentially stuck to these collection plates until they are washed clean during regular maintenance.

Some have claimed that electronic air cleaners are up to twenty times more efficient than the more common air purifiers that rely solely on filters to clean. A HEPA unit can filter 99.97% of the particulates in the air, as small as 0.3 microns in size.

Even though that seems like an extremely high level of filtering, it still does leave room for the smallest particles to go untouched, accumulating over time to considerable levels.

Because all of the particles, no matter how small, are charged and collected through the process employed by the electronic purifiers, they are removed from the air you breath and do not have the opportunity to build into a problem situation.

Many of these types of room air purifiers additionally have carbon filters integrated into the units which are useful for removing odors such a tobacco smoke, cooking odors and the like.

Electronic air cleaners can be found in many different makes and models and they also encompass many price ranges. There are small, stand-alone units that would be appropriate for one or two rooms, medium stand-alone units that would be sufficient for small to medium size homes, and large units that are installed into the forced air system of the home, allowing for air purification throughout the home.

Because we now spend so much of our daily lives indoors -- up to 90% for most people by some estimates, it is even more important to have the environment where we live and breathe be as clean as possible.

Over time, the common products that we use on a daily basis, such as aerosols, cleaners and sprays, become trapped in our modern, airtight homes and can build up to toxic levels.

In addition, the ordinary pollutants that can also build up such as molds, pollen and other allergens, it is clear that it is imperative to take steps to cleanse and purify the air in your home. Home air purifiers will ensure clean air for the health and well-being of you and your family.

One of the reasons for the fact that there are more and more people with allergies and asthma these days is because of the state of the air inside homes, which is said to be 30 times more contaminated than fresh air from outdoors. Electronic air cleaners have proven to be efficient and cost effective in the battle againt indoor pollution.
