    How to Choose

    The two most important factors when buying a fan are price and the cubic feet per minute that the fan can pump. Both are important factors to consider or you might end up buying a unit that is not right for your home.

    Cheaper fans tend to only last a few years while higher priced fans will run for many years and be more powerful. If you only plan on living in your current home for a short period of time, or live in a small condo that does not need a powerful unit you can save some money and go with a lower cost fan. Both RadonAway and Fantech offer fans at a few different price points so you will be able to find a fan on any budget.

    The other important factor to consider is the CFM aka cubic feet per minute the fan can pump. Larger homes with more severe Radon problems will need a fan with a higher FM to clear all the Radon. A high Radon level in your home can lead to a variety of short and long term health problems.

    Which is better: RadonAway or Fantech?

    Both manufacturer good Radon fans but RadonAway tends to be a little better buy for your money.

    Our Final Say

    Radon fans are important to push and vent dangerous, cancer causing Radon gas from you home. All of the fans from RadonAway and Fantech are good choices – if you still are not sure which one to buy we recommend the RadonAway RP260. It is powerful, and almost totally silent so you won’t hear it running while you are sleeping.
