The best basement ventilation systems

The best basement ventilation systems reviewed.

So many basements and crawl spaces are humid and musty due to a lack of clean air. Luckily, an inexpensive basement ventilation system can easily solve this problem. Not only do they allow for a much needed fresh air exchange, but they also dilute basement radon levels, lower the temperature, and help prevent mold growth.

In this article, we will compare various basement airflow solutions, as well as review some of the best basement ventilation systems you can buy.

What does a basement ventilation system do?

These systems function as basement air exchangers by bringing clean, fresh air into the room and expelling excess moisture, sump pump odors, and radon/mold spore infested air out. Not only does this reduce humidity and temperatures, but it also creates much healthier indoor air quality.

Basement ventilation systems vs. dehumidifiers

If you already have a dehumidifier in your basement, then you may be wondering if you still need a ventilation system.

The answer is yes.

A basement dehumidifier is an excellent idea as it removes excess moisture from the air, and thus bringing the relative humidity down, thereby making it impossible for mold to thrive.

However, it doesn’t do anything in terms of cleaning the actual air or diluting it from unpleasant odors, mold spores, radon gas, or other impurities.

On the other hand, using an air exchange system in conjunction with a dehumidifier works very well, because new clean and dry air gets introduced to the basement regularly. Not only does this dilute and expel air contaminants, but it also costs a lot less for your dehumidifier to dehumidify dry air than it does moist air.

How about air conditioners?

An air conditioner in the basement is another great idea. It brings fresh air in from the outside, dries and cools it before pumping it into the room. This dilutes odors and impurities in the air while creating very unfavorable conditions for mold.

So, do you still need a ventilation system?

Yes, you do. The constant flow of clean and fresh air merely dilutes air contaminants. Using an AC in conjunction with a basement ventilation system will work great if you set the fans to expel the air. That way, you will have a constant flow of fresh air into the basement through the AC, while the ventilation fans expel the contaminants.

So the conclusion is that a basement ventilation system can and does work great side by side with a dehumidifier or an air conditioning system.

Tjernlund X2D Reversible Basement Fans

The Tjernlund X2D has two 90 CFM fans that pumps not only clean, fresh air into basements and crawlspaces, but also extracts hot, musty radon and mold spore air.

The two fans can work together in tandem (i.e., both fans pulling in fresh air from the outside or both simultaneously extracting old stale air), or they can work separately (i.e., one fan bringing in fresh air while the other extracts old air).

Another great feature is its built-in humidistat, which continually monitors the humidity level of your basement. You can set the ventilation system to activate itself as soon as the humidity reaches a certain point.

Leaving it permanently on is not a problem either since it only uses a mere 40 watts of electricity compared to the 1,000 watts a dehumidifier uses.

The product, which is manufactured in the USA, has dimensions of 22.9 x 16.6 x 9.2 inches and weighs around 1 lb.

AC Infinity AIRTITAN T8 Crawlspace & Basement Ventilator Fan

The AC Infinity AirTitan T8 has an LCD panel that displays the current temperature and humidity levels. You can also program the fans to respond in different ways depending on the temperature and humidity.

Another great feature is the alarms that notify you in the event of something going wrong with the system.

The heavy-duty stainless steel frame, which houses the twin IP-44 fans, looks modern and is also water and dust resistant, so it stays cleaner for longer. And the DC-Motor is controlled via Pulse Width Modulation (PWM), which makes it extremely energy-efficient and super quiet.

The product has dimensions of 20.5 x 10 x 2.5 inches and weighs just under 6 pounds.
