Ways to Improve Indoor Air Quality
Poor indoor air quality causes allergies, respiratory issues, and headaches. Here are the most effective ways to fix it — starting with the biggest lever.
Shop Mini Splits »1. Upgrade to a Mini Split
Mini splits deliver air directly to each room without ductwork. Ducts harbor dust, mold, and allergens that recirculate constantly. Eliminating them is the single biggest air quality upgrade you can make.

HEPA filters capture up to 99.97% of particles including dust, pollen, and smoke. Replace them on schedule — a clogged filter recirculates what it once caught.
3. Control Humidity
High humidity breeds mold and mildew. ComfortStar mini splits include a dedicated Dry mode that removes excess moisture without overcooling the room.
4. Improve Ventilation
Fresh air dilutes indoor pollutants. Mini splits improve air circulation throughout each zone. Pair with an air exchanger for even better results.
5. Reduce Pollutant Sources
Switch to natural cleaners, use a HEPA vacuum, keep the home smoke-free, and add air-filtering houseplants like peace lilies and spider plants.
6. Regular Maintenance
Clean mini split filters every 4-6 weeks. A clean filter captures allergens; a dirty one just blows them back into the room.
