Best Radon Exhaust Fan for Radon Gas Removal

Radon is a naturally occurring gas.  It is created and released through the breakdown of uranium in soil and rocks. Under normal circumstances, this gas is released into the air, where it harmlessly circulates.  However, it can be very problematic when it enters your home.  Due to the lower air pressure inside your home, radon frequently accumulates in areas such as basements or crawl spaces, where it enters through cracks or other openings in the foundation.  A radon exhaust fan is one very popular method for radon gas removal, recommended by many radon mitigation experts around the world. Learn about the best radon exhaust fan for radon gas removal and mitigation below.

Why Do I Need a Radon Exhaust Fan for Radon Gas Removal?

Radon is odorless and colorless, which means you can’t tell when radon is accumulating within your home.  Even worse, it is extremely dangerous for humans.  In fact, it is the second leading cause of lung cancer behind smoking. 

Therefore, it stands to reason that anyone whose home has tested for high levels of radon would want to remove it immediately. 

A radon exhaust fan is one type of radon mitigation system that draws radon gas from within your home and releases it outside, where it can dissipate naturally.  Radon exhaust fans are considered very effective, as they run continuously to protect you and your family from harmful gas build up.

What Should I Look for in a Radon Fan for Radon Gas Removal?

If you are planning to install a radon exhaust fan yourself, it’s very important that you understand the installation process. Different models will require different procedures, along with various sized PVC pipes and equipment.  Make sure you’re aware of all the details before you get started.

Radon exhaust fans are installed either outdoors or in an attic to prevent pooling of any future leaks.  Therefore, you want to choose one that is fully sealed against the elements or pests.  This will ensure that rain, snow, debris, or small animals do not interfere with the fan unit. 

Frequently Asked Questions

How do I know I have a radon problem in my home?

The only way to determine if you have problematic radon levels in your home is through testing.  Radon is odorless and colorless, so you won’t be able to identify it directly.  Radon test kits can be purchased online, along with radon monitors.  You can test levels by short term or long term, according to the test you buy.  Additionally, you can have a professional radon mitigation team come to your house to test for radon and make recommendations to keep your home safe.

Radon maps have become a popular resource, as they identify areas where high radon gas readings have been recorded. This does not guarantee that your home does or does not have a high level of radon gas.  Since uranium deposits can occur anywhere, your home and your neighbor’s home may have very different radon exposure.  Test your home frequently to ensure you are not being exposed to harmful levels of radon.

My house is brand new.  Could it have radon?

Radon is a naturally occurring gas that is derived from uranium deposits in the Earth.  While radon accumulates over time, a brand new house built over an area with a higher concentration may have high radon levels right away.  Since we cannot observe radon with our senses, it’s best to test every home to be safe. 

What is a dangerous radon level?

The ideal level of radon is zero, but that is largely impossible to achieve.  Around the world, most experts recommend maintaining a radon level that is under 200 Bq/M3.  For reference, the naturally occurring level of radon in the outdoors typically measures between 5 and 15 Bq/M3.

Can radon levels change over time?

Radon levels can fluctuate by the season, by the day, or even by the hour.  As with many natural volatile processes, it’s impossible to predict the rate at which uranium will breakdown in the vicinity of your home, at what rate the gas will be disseminated, and how quickly it will accumulate in your home.  As a result, most radon mitigation processes are permanent and continuous, in order to prevent any potential pooling or greater accumulation.

What’s the best way to get radon out of my home?

When a radon test kit returns results that indicate a high level of radon in your home, you may wish to contact a professional radon mitigation specialist.  This individual will have tools and knowledge to provide further insight into what your radon levels mean, how it might be entering your home, and various methods of keeping hazardous radon levels at bay. 

A radon exhaust fan is one very popular method for removing radon gas. This machine is installed either on the exterior of the home, or in the attic. It connects to a PVC pipe which helps draw radon out of the ground through fan suction, then dispels it safely outdoors.  While the fan itself is fairly easy to install, this process involves drilling through your slab or foundation and installing a significant amount of PVC pile from the foundation to the top of your home. 

Additional methods of radon mitigation that can be used in conjunction with a fan include sealing all cracks and holes in the basement, increasing air circulation or purification efforts within the home, and testing frequently to ensure a leak is not occurring.

Final Thoughts

Radon gas can be extremely dangerous to you and your family.  Once detected, however, you have many options to remove it from your home now and forever.  A radon exhaust fan for radon gas removal will pull harmful radon from below your foundation or slab, and release it safely outside your home.  This helps reduce ongoing accumulation, so that your home can be a safe place once and for all.
