Indoor Air Quality FAQs

Clear answers regarding HEPA filtration, UV-C purifiers, humidifiers, and fresh-air ventilators.

What is the difference between standard 1-inch furnace filters and whole-home HEPA filters?
Standard 1-inch filters (MERV 4–8) are designed only to protect the furnace blower motor from large hair and lint, allowing over 85% of microscopic dust, pollen, and bacteria to recirculate. A whole-home HEPA or MERV 16 media cleaner captures 99.97% of particles down to 0.3 microns, including smoke, virus carriers, and pet dander.
How does a whole-home humidifier save on winter heating bills?
Moist air holds and retains heat better than dry air. When your home is maintained at 40–50% relative humidity, 20.5°C feels as warm and comfortable as 23°C in dry air. Lowering your thermostat by 2°C can lower your monthly natural gas bill by 6–8%.
Are UV-C air purifiers safe for home use?
Yes, 100%. Our UV-C germicidal purifiers are installed inside the sealed metal ductwork of your HVAC system. They produce zero ozone and irradiate only the air passing through your ducts and the AC evaporator coil, safely sterilizing pathogens without emitting light into living spaces.
How often do HEPA and media air filters need replacement?
Unlike cheap 1-inch filters that clog every 30 days, high-capacity 5-inch media filters only need to be replaced once every 6 to 12 months. True HEPA carbon pre-filters are replaced annually, while HEPA core elements last 2 to 3 years.
Can an HRV/ERV system prevent winter window condensation?
Yes! Heat Recovery Ventilators continuously expel humid, stale indoor air (from showers, cooking, and breathing) and replace it with fresh, drier winter air, effectively eliminating excessive indoor moisture and preventing black mold along window sills.
