In recent years, you’ve likely heard dozens of warnings in Fallbrook from newscasters, community publications and local contractors about the dangers of indoor pollutants. That’s a good thing – the air in your home, if left untreated, can be a significant health risk to you and your family. But, how do you choose an air cleaner that will get the job done? Let’s take a closer look at the options currently available and what each of them has to offer.

Air Filters

Air filters are the simplest form of air cleaning. They are designed to capture particles that stay airborne long enough to reach the filter. They don’t work well to capture all large particles, however, because they tend to settle before they reach the filter device. Proper air flow is necessary to supplement the process and remove more pollutants.

High efficiency filters with an MERV rating of 14 or higher are recommended, though HEPA filters (which have an MERV of 17-20) are preferred for their ability to capture particles as small as 0.3 microns. In-duct particle removal is a good upgrade as well because it filters moving air and captures more particles.

Gas Phase Filters

These filters are designed to capture gases produced by building materials, household electronics, paint, and your combustion appliances. They are not always effective for long, so filters must be checked and changed frequently. These systems are not frequently used in home systems, but if you have particular pollutants, they may provide a number of clear benefits.

UVGI and PCO Cleaners

These cleaners are designed to kill pollutants like bacteria and mold. They are usually installed in the ductwork or air cleaner and while the effectiveness of either has yet to be properly measured there is a growing trend to include them in systems where homes experience a large number of allergic reactions or asthma symptoms.

Ozone Generators

There are still some systems that produce ozone as they circulate air back and attract it to a filter for removal. The results are mixed and ozone itself can be a significant irritant to the lungs, so it’s unclear whether these actually work very well.

Which Is Best?

It really depends on the pollutants you’re trying to remove. The best course of action is to have your indoor air tested and then discuss with a contractor the best combination of technologies to remove pollutants from your indoor air.
