The basement is the most frequent place in the home, with poor ventilation, humidity, mold, and several other moisture problems. Because of these common issues basements face, basement ventilation systems are becoming more and more popular among contractors and homeowners.

If you are interested in learning about basement ventilation, keep reading. In this overview, we explain the purpose of basement ventilation systems, basement ventilation fans, and 10 types of ventilation fans on the market.

Without further ado, let’s learn about the best basement ventilation system.

What is a Basement Ventilation System?

The purpose of a basement ventilation system is to ventilate and provide airflow to your underground basement properly. Basements typically lack ventilation, resulting in poor airflow and many moisture-related issues, like mold and mildew.

By installing a ventilation system, however, you can bring airflow to your basement. With the help of the ventilation system, the basement will feel less humid and stuffy.

At the same time, the basement would experience less mold and mildew, and other issues related to poor ventilation and moisture.

Types of Basement Ventilation Systems

For years, contractors have been trying to figure out the best way to ventilate a basement. Given that basements are located underneath the ground, ventilating these areas is much more complicated than ventilating the rest of your house. As a result, there are different types of basement ventilation systems you can choose from.

Here are the two most popular:

Natural Ventilation

Natural ventilation depends on natural air currents using windows and vents. Some basements that are only partially underground can benefit from this ventilation type. However, basements fully underground are not suitable for natural ventilation. More so, some basements will need more than natural ventilation, especially if they are particularly moist.

Fans or Mechanical Basement Ventilation

Fans, or mechanical basement ventilation, are the top basement ventilation systems because they ventilate the airflow and protect against moisture buildup.

You can either install fans with a vent system or install fans strategically around the basement. Basements with natural ventilation often need fans, too, making fans an integral part of basement ventilation.

Fans are preferred between these two basement ventilation types because they ventilate the air and protect against moisture. They also do not let in bugs and other critters you want to keep outside your house.

What does a Basement Ventilation Fan do?

A basement ventilation fan forces airflow in an otherwise stagnant room. Depending on your budget, using a basement ventilation fan can be as simple as putting a box fan in the corner of the room and facing it outwards. For more technical purposes, you can install an exhaust fan and ventilation pipe into your basement.

The more technical form of basement ventilation fans includes both fans and vents. The point of these vents is to provide an exit point so that existing basement air can leave while fresh air is brought in. How many fans and vents you need will depend solely on the size of your basement.

The best ventilation fan system should include a humidity sensor. This humidity sensor will include easy automation, meaning that the fan and vent system will turn on whenever a certain moisture level is detected.

Depending on the design of your basement, fans can be installed in existing window cavities. If these cavities do not exist inside your basement, part of the basement wall may need to get cut so that the fans and ventilation can be placed on the wall.

Pros and Cons of Basement Ventilation Fans

In terms of basement ventilation systems, ventilation fans are the best option for your basement. That is because these fans increase airflow and fight against extra moisture. Even if you have a natural ventilation system, you will likely need ventilation fans, making the fans the best option.

More so, ventilation fans can exhaust out radon and gases. Given that radon is one of the most common cancer-causing gases in America, ventilation fans’ ability to dispel this poisonous material makes them even more advantageous.

Like anything else, however, basement ventilation fans have both pros and cons. Below, you can find a complete list of the pros and cons of installing basement ventilation fans.

Pros

  • Increases airflow
  • Fights against moisture
  • Fights against mold and mildew
  • Dispels radon
  • Lets in fewer pests than natural options

Cons

  • More expensive
  • Vents bring in humid air in humid environments or rainy days
  • May require you to cut out a part of your wall

Best Basement Ventilation System

There are a variety of other basement fans you can choose from. Here are our top ten favorites, ranging from basic box fans to more intensive basement fans designed for crawl spaces and other moist areas.

1. AC Infinity Airtitan, Basement Ventilator Fan

The AC Infinity Airtitan Basement Ventilator Fan is a top ventilator fan on the market. It has a hefty airflow design, complete with temperature control and dampness control. Not only does this ventilator fan increase airflow in your basement, but it also stops mold growth and filters out pollutants like wood gas or radon.

To ensure you get the result you want, it comes with a thermostat, humidity control, and personalize fan speed rates. These are different features that are unique to only high-end basement ventilator options. It also has different modes, including eco-mode. It even comes with backup memory.

2. Durablow MFB M2D Stainless Steel Fans

If you live in an area with a lot of moisture, especially in your basement, you will likely appreciate this Durablow Fan. This fan is made from 100% 304-grade stainless steel, ensuring that the unit lasts no matter the moisture level.

With the vent, the system decreases the moisture levels in the basement and crawl space. It also vents out radon gas and any other odors you don’t like. At the same time, the fans increase airflow, which prevents condensation, mold, mildew, and rot.

3. Tjernlund X2D Model Products Xhanger Reversible Basement Fans

If you are willing to pay a pretty penny for your basement ventilation fan, we recommend the Tjernlund X2D. It is incredibly high-end, with the ability to both dispel damp air and bring in fresh air. Of course, this high-end fan comes with a hefty price tag.

In addition to being reversible, this fan has a thermostat, humidity control, and magnetic draft stops. The magnetic draft stop stops odors and harmful gases from entering your home from the outside, which is a plus.

4. Glass Block Factory Basement Vent

The Glass Block Factory Basement Vent ensures that the system is energy-efficient, secure, and transparent. On top of its unique look, the vent can quickly vent out any excess moisture, smells, stagnant air, and more.

During the winter months, the vent closes, causing the seals to be closed completely. This keeps it safe from outside elements. At the same time, it ensures that the basement and crawl space stays relatively warm during the winter, lowering your energy bills. 

5. Elite-Air Dual Fan Ventilator

The Elite-Air Dual Fan Ventilator is a pretty good ventilation fan system. It has dehumidistat capabilities, allowing the unit to both bring in fresh air from the outside while exhausting humidity and moisture from the inside.

In addition to dispelling moisture, this fan ventilator can dispel radon, wood gases, and odors outside your home. One thing that makes this ventilator system unique is that all of its parts are easily replaceable, making it easy to fix your fan in the case that it should break.

6. Tru North Vent Company Garage Vent 300 CFM

Even though the Tru North Vent Company Garage Vent is specifically designed for garages, it will work perfectly for your basement as well.

This is one of the best ventilation fans. We have placed it towards the bottom of our list because it is designed for garages, not basements. Bigger basements may need two or more of these systems.

Nevertheless, this garage vent easily vents out moisture, humidity, and odors. It even turns on automatically whenever certain humidity levels are reached. It also comes with some protection for the metal fan and plastic housing, which help keep the entire system safe.

7. AC Infinity Airtitan T3

The AC Infinity Airtitans certainly are impressive, which is why we have two models on our list. This model is specifically designed for small, enclosed spaces, like garages, attics, or basements. It’s incredibly affordable and super small, making it easy to use and install.

The system includes an LCD display and thermostat. It also includes an alarm, backup, and timer. In addition to all these fancy features, this basement ventilation fan also offers extreme durability despite its affordable price.

8. iPower Shutter Exhaust Fan

The iPower Shutter Exhaust Fan is a super powerful ventilation system. It has all of the features of many of our abovementioned fans, and it is more powerful. We have placed it lower on our list because most basements do not need a ventilation system of this size.

For larger basements or areas, however, this certainly is a great exhaust option. It’s easy to use and install, though you do need an opening. It also shuts off on its own, meaning you do not have to do it with the system manually.

9. SAILFLO Exhaust Shutter Fan

The SAILFLO Exhaust Shutter Fan certainly is not the most attractive thing in the world. If we’re being honest, it isn’t created with your basement in mind either. Despite these two facts, it easily removes humidity and odor from any basement.

Because of its size, the shutter fan can produce a hefty airflow. It even can exhaust in both directions, which is unique for fans of this kind. The fan is also incredibly durable, with the ability to work up to 9,000 hours. On top of all these features, it is affordable.

10. PELONIS 3-Speed Box Fan

Finally, we’ve gotten to the last ventilation system on our list. This option is ideal if you don’t want to invest in an actual ventilation system. The PELONIS 3-Speed Box Fan is simple, making it affordable, easy to use, and transportable.

However, this is not just your average box fan. This one includes three speeds, allowing full force circulation. The air can even be cool because it has an air conditioner feature built within it.

Of course, a box fan isn’t going to ventilate your basement like the other options on this list, but this may be a great option if you are on an extreme budget or need a temporary fix before selecting the right ventilation fan.

Given that this option is so affordable and valuable in a variety of settings, you certainly can’t go wrong using this as a temporary fan until you find something better. Place it in the corner of your basement and face it towards the inside of the room to create airflow throughout the entire basement.
