We all want what’s best for our families, and that includes keeping them safe from harmful gases/toxins. Radon is a radioactive gas that can be found in small amounts in the air we breathe. It is considered to be a leading cause of lung cancer among non-smokers, and while it can’t be seen or smelled, it could be present in your home.
Luckily, there are ways to discover your radon levels before mitigating them (by up to 90%) if they are found to be high. One of the most effective ways to do this is by installing a radon mitigation fan.
Radon fans work by drawing air from beneath your home and releasing it through an exhaust pipe that goes above your roofline. This process effectively reduces the amount of radon in your home, making it a safer place for your family.
Finding the best radon fan for your home can be a daunting task, but we’ve done the research for you. Here are the five best radon fans on the market, based on factors like price, features, and customer reviews.

How to Choose the Best Radon Fan for Your Home
Even though we've rounded up some of the best radon fans on the market, you might be wondering which one of the models is the best fit for your home. Here are a few factors to keep in mind as you make your decision:
The first thing you'll want to consider is the airflow rating of the fan. This is usually measured in CFM (cubic feet per minute), and the higher the number, the better. Choosing a fan with too low of an airflow rating will make it less effective at reducing radon levels.
Most radon fan brands have models that accommodate 4”, 5", 6” PVC pipes, but there are a few models that can be used in smaller 3” pipes. Be sure to check the specifications of the fan before you buy it to make sure it will work with your existing system.
Level of Protection
Some radon fans come with housing that's been sealed with epoxy resin to prevent air leakage. If you live in an area with high radon levels, this is an important feature to look for. After all, you don't want your fan to be working overtime because of a leak. If you ever suspect a leak, you will have to do a smoke test to locate the leak and then seal it up.
Having a radon fan in your home is the best way to reduce radon levels and keep your family safe, but with so many different models on the market, it can be tough to know which one to choose.
We hope our list of the 5 best radon fans will help you narrow down your options and find the perfect model for your home. Remember to keep airflow, pipe size, and level of protection in mind as you shop around, and you'll be sure to find a fan that meets your needs.
