Q: How long does a radon mitigation system last?

• <div><p>The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.</p></div>

Q: Do air purifiers help with radon?

• <div><p>No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.</p></div>

Q: How long does radon mitigation take?

• <div><p>Installation typically takes 1-2 days, depending on the system and property layout.</p></div>

Q: Why is radon gas abatement necessary for homes?

• <div><p>Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.</p></div>

Q: How often should radon levels be tested to ensure safety?

• <div><p>Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.</p></div>
