Radon is a colorless, odorless, radioactive, and tasteless noble gas. It can be very harmful and can enter your house from the soil over time. Of course, you cannot stop this leakage, but you can monitor levels (with digital/ manual radon detectors) and take corrective measures (with radon mitigation fans) to lower them effectively. Hence, the gas needs to be transported from its source to somewhere outside your house. And what works best depends on your house’s structure and age. But to alleviate the radon gas from underneath your house, you require a radon fan. Therefore, after extensive R&D, we ensure we offer you the best possible solutions for the most complex problems.

What Are Radon Mitigation Fans?
Radon is a gas that’s invisible and forms inside the Earth’s crust. It surrounds each of us as part of the air we breathe. Though radon levels tend to be highest at the lowest levels of a building, some buildings have higher radon levels on the top floors as well. This happens due to the building material used, the natural updraft, or artificial ventilation.
Radon is somewhat heavier than the air we breathe. And generally, it doesn’t go up through the vent pipe all by itself. In such cases, you can install a radon mitigation fan on the vent pipe in the attic and effectively reduce the radon levels. And of course, measuring all the floors for radon helps you make healthier decisions. At last, it’s always advisable to spend more time on floors that contain lower radon levels.
Radon fans are specialized, sealed units that prevent radon gas from escaping. These fans are permitted in the garages, the unfinished attics, or on the outside of a building.
One should use only standardized radon mitigation fans. In the U.S. and Canada, Radon Away and Fan Tech are among the prominent radon fan manufacturers. Their products are UV-resistant, made of UL-listed durable plastic, and have a watertight electrical terminal box. They also feature high-efficiency EBM motorized impellers and thermal overload protection.

How to Choose the Best Radon Gas Mitigation Fan System: Best Buying Guide
Here’s the best buying guide on how to choose the best radon gas mitigation fan system:
Get your facts right
Know that radon is the second largest cause of lung cancer-related deaths in the USA alone. It is deadly and negatively affects your lifestyle. Radon is dangerous for both human and animal health.
Hire or Self-Installation
You can either hire a mitigation contractor to visit your location and evaluate the area to further fix the issue or you can get a DIY test kit to know the levels. If the levels are higher, a radon mitigation system is installed to vent radon out of your home. But, how do you choose the best mitigation system? Keep reading further …
Pricing
Your budget is important. So, even before considering other factors, be sure of the price you are willing to invest in.
Size & Type Of Radon Mitigation Fan System
(I) Room Pressurization Fans –
These are designed to draw contaminated air into the basement areas rather than venting it up and outside. Easy to work with, these easily change the air pressure below the house.
(II) Low & Medium Power SSD Fans –
Installed in newer constructions, these systems are noiseless and durable. 3-4-inch piping accelerates significant exhaustion. Being low in power, they also save electricity.
(III) High-Flow SSD Fans –
These are retrofitted in your property to prevent any leakage and work beneath the foundations where the sub-slab layer is porous. Therefore, 4-6-inch piping exhausts well, and 6-10-inch piping is better for industrial use.
(IV) Suction SSD Fans –
These are good for areas where the sub-slab materials aren’t too porous. So, get 3-inch piping along with multiple penetrations, and it’ll efficiently draw out enough air.
Place Of Installation
Choose a mitigation fan based on your house’s construction and the installation location. You can either fix the system in your basement, attic, garage, or outside. Beneath the foundation is an option for properties that are still under construction.
Noise
Modern radon mitigation fans do not make any noticeable sounds. Standard wear and tear may lead to some buzzing later, as the bearings lose their lubrication. However, these are usually silent. So, make the choice accordingly.
Durability
The material of the entire system matters the most. If the pipes or fans aren’t durable enough, your system won’t last for long.
Manufacturer
The company must be registered and licensed to sell the system. It must also have authorized agents for installing the radon removal system.
Other Aspects
There’s no single buyer’s guide to look up, since there are so many factors to pay attention to. We have here tried to cover the most basic as well as the essential ones. However, you can also look up a few other things mentioned below:
- Under a warranty/ guarantee model
- After-sales service
- Efficiency
- Power
- Overall performance
Why Use a Radon Gas Mitigation Fan System?
Here’s why to use a radon gas mitigation fan system:
- It helps maintain a lower in-home radon level.
- The system keeps the house moisture-free.
- It remains noise- and vibration-free and runs without obstruction.
- It is a cost-effective solution to mitigate radon.
- Low radon levels mean a high quality of life.
- A radon gas mitigation fan system minimizes the risk of radon re-entering the property.
- It also regulates the flow of radon gas on the outside.
- A radon mitigation system reduces the risk of developing lung cancer.
- Standard radon-reduction systems are usually effective within 24 hours and maintain low levels as long as the fan is operating.
- Having the vent stack opening above the roof space of the house allows the radon contractor to place the radon system exhaust farther from doors, windows, and other openings.
- Radon fans inside the attic space or basement are better protected from the freeze-and-thaw cycle. Electrical components remain safe and inaccessible to kids or even pets.
- Another advantage of this system is the reduced infiltration of moist soil air, which may condense humidity in the basement of your property.
How to Use the Radon Gas Mitigation Fan System?
Here’s how to use a radon gas mitigation fan system (DIY installation):
The primary source of radon is soil or the surface below your house. Therefore, the basement or levels beneath are the target areas. PVC vent pipes are fixed and neatly sealed to prevent any leakage. You need to drill holes around the piped outline with a rotary hammer. Take the required steps if the fill is dense. Use a demolition hammer to chip out the hole for the PVC vent pipe.
Dig out enough dirt to create a pit approximately 20 inches in diameter. Route it up through the walls and onto the roof space. Fix a foam rubber rod around the pipe’s base to prevent any future leakage. Place the exhaust fan outside the living areas of your house – attic, garage, or outside (as per convenience). This is mandatory for a radon mitigation system, as it protects you from radon leaks: the fan pulls radon up and expels it outside. The next step is to seal the pipe with hydraulic cement. Hence, constant monitoring of the installed system is important.
Finally, ensure the system is running: drill a small hole at the end of the foundation for testing, turn on the fan, and use a lit piece of paper to see if the air is being sucked. If yes, the system is up and running, sucking air from across the foundation to the site of the mitigation piping.
Do not forget to install a monitor in the basement to keep a check on the system and whether or not it’s creating the differential pressure necessary to suck air up from the ground.
Frequently Asked Questions for Best Radon Mitigation Fans Reviews– FAQs
Here are some of the frequently asked questions regarding the radon gas mitigation fan system:
Q1. How do I know if there is radon gas in my house?
Answer: First, evaluate the health condition of your family members. The signs and symptoms aren’t very evident; however, kids and the elderly are primarily affected. Signs may include mild chest pain, wheezing, hoarseness, persistent cough, bronchitis, and loss of appetite. Prolonged radon exposure can eventually lead to death if the symptoms go undetected.
Second, test your home with a manual radon gas test kit or an electronic radon gas detector. The two are a handy option and affordable to help you get started.
Third, you can call a professional if you suspect radon particles are present in your surroundings, or if your neighborhood is affected by the problem.
Q2. What do I do when I detect a leakage?
Answer: Call for professional help, or simply get your brain to work.
Expert assistance is convenient, as he/ she can take on the entire responsibility of resolving the issue. However, the service may not be economical. So, if you don’t want to call a specialist, you can opt for a DIY fix. Once you are aware of the levels (after evaluating with a DIY kit), install a radon mitigation fan system. It’s a simple pipe-and-fan system that sucks the radon particles from your home and vents them out of your property.
Q3. Where is the radon mitigation system installed?
Answer: The system is either installed in the basement of your property or the attic – the two main affected areas.
Q3. How long will the installation take?
Answer: It takes about 3 to 5 hours to install a radon mitigation fan system efficiently.
Q4. Does it make any sound or vibrations?
Answer: Yes, it certainly makes some noise; however, it is negligible, and no significant vibrations are felt.
Q5. Are there any other methods for radon removal?
Answer: Sub-slab depressurization is the commonly used radon mitigation process. You can, of course, take corrective measures such as sealing cracks, but installing the mitigation fan is a must.
Q6. Is the mitigation system too expensive?
Answer: The cost of the radon mitigation system may vary. There is no fixed price. Depending on the products you choose, the services you select, the complexity of your property, or any pre-installed passive system, the price may increase or decrease accordingly. However, on average, anything between $800 and $2000 is what you’ll have to spend.
Q7. What Radon levels are safe?
Answer: Essentially, no radon levels are considered safe for your well-being. However, a standard number is acceptable – 4 pCi/L. And anything above this is considered highly dangerous.
Q8. My house came with a built-in passive radon removal system. Is that enough?
Answer: No! You will still have to install an active radon removal system to vent the gas out from the pipes and lower the levels. Passive systems aren’t too successful.
Q9. My neighborhood has low radon levels. Does that mean I don’t have to worry about my property?
Answer: Radon levels constantly change throughout the year and from area to area. Your neighbors may not have any radon particles in their homes, but you may still be exposed to higher levels and vice versa. So, test for radon and determine whether your property is safe or needs preventive measures.
Q10. The fan remains outside the house, and bulky PVC pipes go from the basement to the roof. Why?
Answer: Why is the system outside? EPA protocols! Inside installation isn’t always feasible for all kinds of properties. The rubber coupling can leak. And, the conditioned air can be extracted from the home. This is why some people prefer having the system outside the house!
Finally, piping rises to the roof to prevent exhaust gas from returning to the property. Therefore, the exhaust is at least 10 feet off the ground, away from the roof and windows. Also, metal downspouts are EPA-approved piping materials.
