Medical professionals often suggest employing room or whole-house air cleaners to alleviate conditions like asthma, hay fever, chronic bronchitis, emphysema and other serious respiratory conditions. Air cleaners use technology to trap smaller-sized particles, as well as a variety of contaminants, that standard HVAC air filters can’t address. Here’s a look at the types of air cleaners available, and the type of contaminant(s) they target:
- HEPA filtration – High Efficiency Particulate Air (HEPA) systems work in conjunction with the furnace and air conditioner. Using a dedicated blower, the system pulls a percentage of the air flowing through the HVAC system, and then filters the air through its high-efficiency filter, and then restores it to the main airstream. The filter is able to trap nearly 100 percent of particles 0.3 microns or larger in size. Some units capture particulates even smaller than that.
- PUREAIR Air Purification System– Attacks all three classes of indoor air contaminants—particles, bioaerosols and odors/chemical vapors. Uses MERV 16 pleated filter. Removed over 95% of particles down to 0.3 micron. Removes over 90% of bioaerosols and microogranisms down ot 0.01 micron. Removes and destroys household odors and chemical vapors. Does not generate ozone; destroys ozone.
- Germicidal air cleaners — This air cleaner uses ultraviolet (UV) lights to destroy cells at their core. The UV rays penetrate into the cell’s DNA so that they can’t reproduce. At this phase, the contaminants such as bacteria, viruses and mold are no longer a threat to air quality.
Before purchasing a system, consider these important factors:
- Choose a system with the capacity to address the entire home’s square footage (for whole-house air cleaners) or one particular room (for portable units).
- Know how to change the cleaner’s filter, as well as how often it must be done and the cost of the filters.
- Estimate annual operating costs.
- Take noise production into consideration.
