2020 Review of Top 5 Best Radon Mitigation Fan Kits Worth Investing In

Yes, it may be in the air that you breath. It is radon gas. Radon mitigation fan kits are used to reduce Radon gas levels, a gas that comes from the natural breakdown of chemical elements in soil, rock and water that typically moves from the ground to the air. It seeps through the cracks of the concrete wall and gets trapped indoors. It is potentially deadly radioactive gas.

Needless to say, you and your loved ones breathe in radon in your home. Just like microscopic bacteria, radon gas lurks around your house. Especially if your house is very well insulated, tightly sealed and located near or on soil that contains high levels of uranium, thorium and radium.

Study shows that radon gas can be detrimental to the cleanliness of cells in the lungs. Breathing in high levels of radon can lead to cancer. The best way to know if you have radon lurking inside your home is to have it tested for radon gas levels. You can either get yourself a radon detector device or hire professional help to do the testing.

With all that, you cannot be too sure that your home is safe from radon. The only definite way in order to test your home for radon levels is through time-tested radon detectors that have met and exceeded the minimum accuracy and performance criteria that the U.S. Environmental Protection Agency (EPA) has established or hire a professional to do the inspection. 

Through radon mitigation systems, radon concentrations in the indoor air is reduced to a level wherein it is less dangerous to the health and would not be as detrimental. If the radon level test result is 4 pCi/L or higher, the EPA already recommends the place to have a radon mitigation system.

There are two types of radon mitigation systems: active and passive. Passive radon mitigation systems does not use a radon fan as part of it. Active mitigation systems on the other hand have the radon fan as the core of its system. The fan does the suction work.

Radon Mitigation Fan Kit and What It Does…

Designed and manufactured to mitigate and prevent radon gas in your home, radon fans serve as suction systems that pull the radon from beneath the soil or ground where the sump hole is located then vented outside your home. In simpler words, radon fans work as ventilation that keeps radon gas from seeping through the cracks of your home structure. They prevent the rising of radon gas to dangerous levels.

The reason why a radon mitigation fan is highly recommended is because other ways to mitigate like sealing cracks on the floor or walls where radon gas can penetrate does not really lower the radon levels. Radon fan serves as ventilation that keeps the air you breath at home is safe. Through a piping system in the slabs, the fan sucks the air from the ground and releases it outdoors. This way, lesser radon gas penetrates your home.

Tips for Choosing the Best Radon Mitigation Fan Kit

When choosing the right radon fan to use in your home, here is a list of tips that you can put into consideration

1. Know the soil where your house is built on​. The performance curve of the fan heavily depends on the soil conditions under the radon suction point. Dense or porous soil? Both types need different radon mitigation fans. So before you plunge into purchasing, make sure you do your own research on your area’s type of soil and the radon levels it releases.

2. Devices with a strong suction emits a humming sound​. Do not be so particular with the noise the radon mitigation fan emits. Any kind of device that does require a fan working to pull in air will create a humming sound. Nevertheless, majority of radon mitigation fans are guaranteed to perform quietly.

3. The noise does not always mean the fan or the unit is broken​. Noise can also be attributed to the hardware, piping, and installation procedure. Most manufacturers include a manual for installation that tells exactly the proper way to mount the unit, to connect pipings and all that is done to make the unit operate efficiently.

4. Make sure that the product is ETL or UL listed for outdoor use​. ETL is proof that the manufacturing of the final product complied to the North American safety standards. UL stands for Underwriters Laboratories, an organization that ensures that products are safe for its particular use and certified.

5. Check the structure of your home, study your walls and choose a prospective location for the fan. ​Before you choose a radon mitigation fan kit, you have to know the location where you will place it. Available radon mitigation fan kits vary in size, shape and structure.

Here, in no particular order, we rounded up the top best radon mitigation fan kits that are highly rated and have been the top performers for many years. These radon mitigation fan kits are commonly bought together with a manometer for homeowners to know that their radon mitigation fan unit is working.

Without further ado, here is a list of the top best radon mitigation fan kits we selected for your radon problems.

Benefits of Using a Fan on a Radon Mitigation System

Besides the major advantage you get from installing a radon mitigation fan is the fact that it reduces the dangerous high level of radon gas you inhale inside your home, here are more reasons why you should install the fan to help reduce radon gas in the air your breath at home.

1. Moisture removal

Through the process of sucking air from the ground, the strong impeller fan can also remove moisture that accumulates. It is released into the air outside together with the radon gas. Most radon mitigation fan kits have built-in systems in order to counter the moist that enters the pipes.

2. Dries the slab and the basement

Dry ground is the way to describe it if the moisture is removed. Termites and other ground pests are attracted to and thrive in wet environment, a drier slab is less conducive and hospitable to them.

3. Cost-efficient, durable and quiet operation

You must be thinking that another device installed in the house is added expense to the electricity bill but radon mitigation fan kits are manufactured and designed to resist outdoor climate and UV resistant that makes it durable over the years and years of continuous operation. So, it basically pays itself for the benefits and assurance they give you that no radon gas is inhaled by your loved ones at home.

Most radon mitigation fan are also factory tuned to quietly operate. Well installed piping system and right hardware used eliminates the loud humming noise the fan can produce.

4. Interior or exterior installation

Depending on your preference and the structure of your home, you can primarily place the radon fan mitigation fan indoor or outdoor. Now, hold your horses, indoor doesn’t mean the fan will release the radon air inside your home, it just means that it is installed in the attic and radon gas is still released outside your home.

Most homes have their radon fan installed outside but there are several reasons as to why installing the radon fan inside your home is more beneficial. The main reason is that the fan and the electrical components are out of reach and protected from the climate outside as well as less obtrusive.

Now that you have quite knowledge on radon and the active mitigation system, the next step is quite crucial which is choosing the best radon mitigation fan as there are a variety of options.


How Radon Mitigation Fans are Installed

1. Get your home tested for radon levels

The initial step to mitigating radon in your home is to check the levels of radon present indoors. You can do this by administering short term or long term radon test kit procedures. These tests are sent to the laboratory where they count the radon level. Today, where everything is highly advanced, there are radon detectors that costs less, saves more time, and meant for continuous measurement of radon levels. These, you can use, even after you get a radon mitigation fan installed already.

Bottomline, you’d want to purchase a long term device that you can use before, during and after fan installation.

2. Know the age of your house structure

The next step is to know the age of your house. This is needed in deciding how to suck the air from the ground through the system. If the house was built mid 1970s then the fill that is poured under your house is not ideal for an easy DIY active mitigation system. A very ideal landfill is porous where gas can easily breathe. Which makes suction easier. Whereas a non-ideal fill would be a dense soil or earth – either very wet or damp and rocky. You will need to put in more effort in figuring out the system for dense fill. Soil composition is also inspected.

3. Analyze your house’s structure and foundation

Before you purchase piping and even the radon mitigation fan kit, you have to analyze your house’s structure for a few reasons.

First, in the case of additional section of the house. If after the piping system has already been on its initial construction, there might be a need to mitigate radon from several areas of the home. This situation complicates the DIY radon mitigation system installation.

Second, there may be current drainage systems. Inspect your house, there may be a french drain or drain tile laying somewhere where you can draw radon up out of. In this case, there is no need to drill through the slab.

Lastly, seal off all current foundation cracks. Make sure that you check where the pipes go through the slab to ensure that there is no hairline cracks and every small hole is plugged and sealed. This is to give the mitigation system a good suction level.

4. Plan the piping placement

Regardless of the radon mitigation fan kit your purchased, you will want to use a PVC pipe that is 3 or 4 inches in diameter. Choosing the right pipe and hardware to connect to the fan is essential because it is a great factor if you want to lessen the vibration as well as the humming sound it may produce.

It is highly suggested that you run the pipes through the basement into an attached garage that leads to garage’s roof. Running your PVC pipes through your home, can reduce condensation. It is not advisable to run it through areas in the house like the living room, kitchen, or entertainment room as it looks intrusive.

The pipe needs to come out of your roof that is 10 feet away from windows on a horizontal plane. It also must extend a little over 1 foot above the roof’s surface.

5. Place the chosen radon mitigation fan kit

In the attic, the garage or outdoor, these are the areas where you can place your fans. But never in the basement, crawl spaces or even in the living room. This is to ensure that in the case of leakage.

6. Drill holes

An ideal spot is anywhere near a wall where you can bracket the PVC piping to, of course this will also heavily depend on where the fan is mounted and installed. Make sure you measure the hole slightly larger than the PVC pipe.

7. Lay pipes Laying pipes starts from the roof down to the basement. Make sure that the pipes are sealed and bracketed to the wall. To complete the system, you need to attach the fan to the piping structure.

8. Seal holes tightly

Caulk and use hydraulic cement to seal the roof and the foundation slab.

9. Test the installed system

Finally, the only way to test if it works is to plug it in and let it do what it is meant to do. By now you know that purchasing a radon detector has more long term use compared to charcoal test kits. Installing a manometer on the basement piping will tell you whether or not the radon mitigation system you have just installed is creating the pressure differential necessary to suck the radon gas from the ground.


Radon Mitigation System Maintenance

For the most part, you can take care of the fan and piping yourself and may require little or
no professional maintenance. However is worth noting that in case something goes wrong with your fan some brands will not honor the warranty it the fan was not installed by a professional.

1. Radon Fan Unit

The radon fan is the heart or the core of the device. It is running 24/7 and for as long
as you have it turned on. Radon fan typically have an average lifespan of 10 years. If
in case the fan starts to get excessively noisy, consider cleaning it, have the bearing
checked or have it replaced.

2. Radon System Manometer

The next vital item in the maintenance of a radon mitigation fan kit is a manometer. It
is a red and blue liquid-filled glass tube with a number scale and an air tube from the
manometer going into the radon pipe. The purpose of a manometer is to display
whether the pipe is being depressurized by the fan and it basically tells you that the
fan is up and working.

3. Condition of the radon piping and exterior piping

Frequent inspection of radon piping as well as the exterior piping should be done so
as to verify that there is no air leakage. To protect the part of the PVC pipe that
penetrates a concrete slab, edge should be caulked and sealed.

4. Professional testing

After all the self-inspection of the mitigation system, it is recommended to have it
professionally tested and checked. It’s extremely hard to fix issues with the
radon mitigation fan. EPA recommends homes to have their radon mitigation system
to be checked every 2 years to verify its safety and functionality.

FACT: Radon gas that has been released in the outdoors which mixes to the outdoor air is no longer dangerous to the health. The radon gas that comes directly out of the soil that seep in through the cracks of the floor making its way to your house, that is dangerous.
