A decibel (dB) measures the intensity of sound.
A micron is a very small unit of measure equal to one millionth of a meter. Airborne particles such as dust, smoke, dander, or bacteria are often .3 microns or less, and can only be captured by an indoor air cleaning system.
Dealers can answer questions, help you find the right products for your home, and repair your system.
