Got a stale, stuffy, or damp-smelling basement?
Looking for the best way to make it smell fresh and clean again?
Then the information in this guide is exactly what you need.
Below, we’ll teach you how to air out a basement in the simplest way possible that’s guaranteed to get results.
By following these three simple steps, you’ll have an aired out basement that’s pleasant to be in.
But First, The Importance of Airing Out a Basement
If your basement has suffered from flood damage or any other severe water issue, like busted plumbing, then the reason for airing it out is obvious.
However, airing out a basement even when you don’t have water problems, is also a good idea for several reasons, including:
- It’s good for your health — Few harmful particles are floating in the air.
- It makes the basement smell better — An aired out basement smells always smells fresher.
- It reduces mold growth — Mold can’t grow in a properly aired out basement.
- The air circulates better — This keeps the air from being stale and collecting dust and other pollutants.
- Furniture doesn’t get damaged — Damp and stuffy basements cause wood rot and rust to occur on furniture. A properly aired out basement doesn’t have those issues.
How to Air Out a Basement in 3 Easy Steps
Step 1: Open Windows (If Available)
If your basement has windows, then the first thing you can do is open all of them to let the air circulate.
Exchanging outdoor air with indoor air in a basement is an easy way to keep it fresh.
If you have both a window and a door that opens to the outdoors, a good tip is to crack the window slightly while opening the door all the way.
This trick will draw outdoor air in from the window and force a large amount of indoor air through the door.
Another trick you can in a basement with windows or a door is to add a small room fan to the room.
Setting the fan up to blow out the door or window will help facilitate the movement of indoor air to the outside.
Using a fan in a basement also keeps the air moving which improves the overall ventilation.
Step 2: Run an Air Purifier
The second best option for how to air out a basement is to add an air purifier to the room.
An air purifier is also the only choice when you don’t have windows or an exterior door in your basement.
Air purifiers are special devices that are designed to clean indoor air.
They do this by pulling room air into the machine with a small fan, blowing it through a set of filters, and then returning the cleaned air back into the room.
The best air purifier for basement can eliminate up to 99.97% of harmful particles that collect downstairs as well as reduce the odors associated with those particulates.

One thing to consider in an air purifier purchase is the size of the room the machine is designed to work in.
It’s a good idea to get a slightly more powerful air purifier than your basement can handle so you can ensure that it’s working at peak efficiency.
The guide linked to in the previous paragraph explains all about sizing an air purifier for your basement and more.

Step 3: Run a Dehumidifier
The final thing you need to do to air out your basement is to add a dehumidifier to the room.
Too much moisture in the air leads to mold growth, moisture rot, and a damp, musty smell.
To get rid of those issues, you’ll need a dehumidifier.
A dehumidifier does exactly what the name indicates — it “de-humidifies” the air.
Which is a simple way of saying that the machine removes moisture from the air (i.e. humidity).
Dehumidifiers consist of a fan inside the unit that draws in room air.
The air is then cooled and the moisture is stripped from it before the air is pushed back into the room.
The moisture (i.e. water) that’s filtered out of the air is collected into an internal bucket.
After a certain amount of water is collected, the dehumidifier will turn off so it doesn’t spill the water out on the floor.
A hose can also be attached to many dehumidifiers as a way to bypass the bucket.
This frees you up from having to empty the bucket when the container fills up with water because water will just drop out into the hose.
The hose can be directed to a floor drain, outside, or into a sink if you’re dehumidifier has an internal pump to push the water up vertically.
