“Radon extraction system” has about 140 searches per month. The site ranks around 58th. Extracting radon means sucking the air from under the slab and expelling it outside. It is not a filter placed in the living room.
Three Devices, Three Roles
- An air purifier or filter treats the air already in the room. It does not prevent gas from entering through the slab.
- An air exchanger dilutes indoor air with outdoor air while running. It does not block radon entry.
- The mitigation fan continuously sucks air from under the concrete. This is the mitigation system.
If the 91-day test exceeds 200 Bq/m³, changing the furnace filter does not fix the slab. The standard installation costs $2,799.99 + taxes, price confirmed before work, with 5% off under a comparable written quote. The quote indicates if your home remains at this amount.
