Radon Detection and Reduction questions, answered by experts

Properties should ideally be tested for radon every 2 to 5 years or sooner when changes to the property structure or ventilation occur that might impact airflow.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
