These and other indoor air quality products help improve air circulation and balance humidity levels. Unlike electric air cleaners, air purifiers and cleaners products, clean the air without producing ozone, a known lung irritant. Whole-home filtration systems are ranked # 1 by consumers as they provide optimal home comfort and air quality, with no additional energy costs. The simple pleated replaceable filters are labeled with MERV (Minimum Efficiency Reporting Value) rating, which describes the size of the holes that allow air to pass through the filter. The higher the MERV rating (typically ranging from 1 to 16), the smaller the holes, the better the filtration. MERV 10 media offers an ideal 85% removal of particles such as pet dander and mold spores down to 3 microns while MERV 16 Pleated media filter removes over 95% of particles ranging in size down to 0.3 microns as well as removal of 90% of bio-aerosols and micro-organisms down to 0.01 microns dander and mold spores down to 3 microns.
