Understanding Home Air Purification


Indoor air can be 2-5 times more polluted than outdoor air due to cooking fumes, pet dander, dust mites, and volatile organic compounds. These microscopic particles and gaseous pollutants circulate continuously through your home’s air supply, affecting every breath your family takes.


Air purifiers remove microscopic particles, allergens, bacteria, and viruses from your home’s air supply using various filtration technologies. The most effective systems integrate with your existing HVAC infrastructure to provide continuous air cleaning throughout your living space.

HEPA (High Efficiency Particulate Air) filters represent the gold standard in air filtration, capturing 99.97% of particles 0.3 microns or larger. These true HEPA filter systems excel at trapping dust, pollen, pet dander, and other airborne particles that trigger allergies and respiratory issues.


Clean Air Delivery Rate (CADR) measures how quickly an air purifier cleans air in a specific room size, while Air Changes Per Hour (ACH) indicates how many times per hour the entire room’s air gets filtered. For optimal air quality, experts recommend 4-6 ACH in living spaces.


Most air purifiers work by drawing air through multiple filter stages, including pre-filters for large particles, HEPA filters for microscopic contaminants, and activated carbon filters for odors and gaseous pollutants. The vast majority of effective systems combine these technologies for comprehensive air cleaning.
