Indoor Air Quality
Breathe cleaner air inside your house than outside.
Whole-home air filtration, UV purification, and humidity control for OC homes. Made for wildfire smoke, pollen, and pets.
About indoor air quality
Indoor air quality systems sit inside your HVAC ductwork and clean every cubic foot of air as it cycles through. The result: 99.97% of airborne particles removed, including wildfire smoke, pollen, mold spores, viruses, and pet dander. If you have allergies, asthma, or a kid who comes home wheezing during fire season — this is the upgrade that actually moves the needle.

Common questions
FAQ
- Will this help with wildfire smoke?
- Yes, dramatically. A whole-home MERV 13+ filter cuts smoke particle count by 80–95% during fire season. UV adds another layer for VOCs in the smoke.
- What about portable HEPA units?
- Good in one room. A whole-home system cleans every breath of air in the house every 2–3 hours. Different category of clean.
- How often do I replace the filter?
- Whole-home media filters last 12–18 months — way longer than 1" filters at the air handler. We remind you when it's due.
