The Importance of Indoor Air Quality

Clean air is a vital part of everyday life. It affects our lungs, blood circulation, heart, and overall physical health. However, it’s possible that the air inside your home is dirtier than you think. According to the Environmental Protection Agency, the concentration of certain pollutants is often two to five times higher indoors than outdoors.

What Makes a Good Heavy-Duty Air Purifier?

A good heavy-duty air purifier should have at least two stages or layers of filters designed to trap different types of pollutants like dust, smoke, or pet dander. These machines should be able to cover larger areas without losing efficiency when removing pollutants. A high Clean Air Delivery Rate (CADR) rating is also a crucial factor, as it measures how quickly an ionizer removes harmful particles from the atmosphere.
