INDOOR AIR QUALITY Q&A

Straight answers before you call.

Can't find yours? Our full Q&A covers 60+ topics, or talk to a real person 24/7.

What MERV rating should I use?

MERV 13 catches smoke and most allergens without starving airflow on a properly sized media cabinet. Thin 1-inch MERV 13 filters often restrict airflow too much.

Will a humidifier damage my home?

Not when it's controlled. We install an outdoor sensor that lowers the setpoint in cold weather so windows don't condense.

Do UV lights actually work?

They keep the coil free of mold and biofilm, which improves airflow and odor. For particles you still need filtration.

How much does whole-home filtration cost?

Media air cleaners run $700 to $1,400 installed. Humidifiers $900 to $2,200, and ERVs $2,800 to $4,500.
