The 9 Best Radon Fans
This wiki has been updated 13 times since it was first published in November of 2018. If you know or have reason to suspect that radon is present in the soil around your home or business and are worried about the adverse health effects that are known to follow long-term exposure, consider installing a radon fan. Using negative pressure, these devices help to prevent the buildup of the dangerous gas indoors by venting it safely through a system of pipes to the outdoors.

In this update we removed the Systemair HP190 due to availability concerns. We added the RadonAway RP260, a similar unit that can withstand moist environments and is not wall-mounted, supported instead merely by the piping connected to it. We also decided to add the Tjernlund RMS160, a wall-mounted option with an adjustable ventilation hood, flexible mounting options, and a motor that's not exposed to moisture, though this choice also tends to be rather loud.
If you're looking for a more basic fan to install in a ventilation system which doesn't need to dispel dangerous particles, check out these inline vent fans, which tend to be cheaper than the more specialized options shown here.

Added the Fantech Slimline for its noise reduction mounting system and ability to remain concealed within a home's walls. The NuTone In-Line offers a permanently-lubricated internal motor and powerful centrifugal blower for accommodating long air ducts. Also included the RadonAway GP501 for its dependable seams. Added both the Durablow M2D and AirTitan T8-N, as they offer dual-fan designs that are ideal for placement in crawl spaces.
