How to choose a radon mitigation fan

Not all of these fans are created equally so there are a few things you may want to consider before choosing one.

Are radon fans noisy? Noise levels are something you may want to consider, especially if you live or will be spending a lot of time in the same room as it. Just keep in mind that a noisy radon fan is by no means a sign of a low-quality product, but if you will be spending a lot of time in the same room, you may want to get a whisper-quiet system.

What size radon fan do I need? Fans typically come in sizes of 3, 4, 6, and 8 inches. Also, figuring out the size you need will depend on several factors such as the square footage of the space it will be used in, the current radon levels of the room (this can be determined by a long-term radon test kit or a radon detector system) and the building type (for example, crawl space, basement, etc).

Generally speaking, a 3-inch radon fan will be well suited for a space of 149 square meters or less, while a 4-inch fan will be able to cover a room of no more than 232 square meters. Anything above a 232 square meter space will require a 6 or 8-inch fan.

When in doubt, call a licensed and professional radon expert to come take a look. Also keep in mind, that bigger is better than smaller because the last thing you want is a small radon fan that is unable to extract large amounts of radon quick enough.

Type of radon mitigation system: The type of radon mitigation system you choose will determine how easy it is to install. A sidewall system is the easiest as it requires no PVC pipes. A regular system relies on PVC pipes to pull the radon gas to the outside.

Energy efficiency: Energy efficiency is something that should always be taken into account – especially if you will be running the fan constantly. Luckily, there are many mitigation systems on the market that will allow you to run it permanently while having very little effect on your energy bill.
