Air Purifier for Basement: Buying Guide

Why Buy an Air Purifier for the Basement?

air purifier for basement

Basements are often dark, cold and damp spaces susceptible to breeding mold spores and accumulating dust particles, bacteria, and allergens.

People often complain of breathing troubles as soon as they enter their basements. One of the main reasons for this is because basements aren’t cleaned very often and easily accumulate dust, allergens, mold, and bacteria, primarily because most of the time, they are poorly ventilated, dark, and damp spaces.

All these factors make basements the perfect breeding ground for bacteria, viruses, and dust accumulation.

This is where an air purifier comes in and solves all the trouble. Forget the musty, foul smell and the incessant coughing you experience as a result of breathing in the mold-affected dust accumulated in the basement.

The purified air coming out of an air purifier is both fresh and clean, thus making breathing easy for you.

An air purifier is equipped with multiple filters that capture particles as small as 0.3 microns and remove foul odors and smoke. This improves the air quality of the basement, making it safer to breathe in.

What to Look for When Buying an Air Purifier for the Basement

There are many air purifiers on the market, but which one should you choose?

There are a few features and factors to consider when buying an air purifier that set apart a good unit from a bad one. These include:

Filtration System

The filtration system of a unit is of utmost importance. It is always better to opt for a unit with a multi-stage filtration system instead of one with a single filter.

This is because the former is more effective and efficient. In a multi-filter system, the air goes through different cleaning levels, and the harmful pollutants present are more effectively removed. 

Particle Removal Capacity

The air purifier you opt for should at least have a HEPA filter as it can remove 99.97% of particles, pollutants, and allergens as small as 0.3 microns.

Basement Size/Coverage Area

Before investing in an air purifier, measure your basement area to determine the area coverage of the air purifier you need. You should opt for an air purifier that is compatible with your basement size and can effectively clean it.

Modes of Operation

The air purifier you opt for should have a customizable operation. This essentially means that it should come with multiple fan speeds and timer settings to adjust the operation according to your convenience and your basement’s air quality.

Noise Level

If your air purifier is too loud, it will disturb you, especially if you intend to use the same air purifier in your bedroom for sleeping at night. It is better to opt for a unit that operates at low noise levels.

Energy Efficiency & Operating Cost

Your air purifier should work effectively and efficiently in terms of energy consumption.

Look for a unit with an Energy Star certification. This makes sure the operation cost stays low. Regularly maintaining the unit also allows it to work efficiently.

Build Quality & Aesthetics

Generally, cheap air purifiers compromise the build quality, making them more susceptible to damage if not used very carefully.

It is better to choose air purifiers with a sturdy build, like machined aluminum or good-quality plastic, to ensure durability. Air purifiers come in different colors and finish to choose from to match your home aesthetic perfectly.

Price Vs. Usage

Air purifiers are available at all prices, starting from $100 and going up to $800.

You need to select a unit that effectively removes mold from your basement alongside other pollutants and gives you the best value for money according to your usage.

Mold build-up can be harmful to your health if not diligently dealt with, which is why a good-quality air purifier is an excellent long-term investment.


It is best to choose a unit backed by a good warranty service of at least 3 to 5 years. This makes the product more reliable. The brand’s customer service should also be good in case you need help with installation or figuring out a feature of the unit.

Pros and Cons

basement air purifier

Still on the fence about whether an air purifier is a great investment to rid your basement of mold?

Let’s take a look at some of their pros and cons to help you decide better


  • Can remove foul odors caused by mold spores
  • Remove bacteria, allergens, and microorganisms
  • Energy-efficient operation
  • Removes pet dander and hair
  • Equipped with a quiet operation mode


  • Requires maintenance over time
  • Can be expensive

Frequently Asked Questions

How to Choose the Air Purifier Size for Your Basement?

The first step to selecting the right air purifier size is calculating your room area. Measure and multiply the length and width of the room to calculate its square footage. If you need an air purifier for multiple rooms, measure the square footage of each room and add them.

Let’s say the calculated room size is 400 square feet. In this case, you will need an air purifier with CADR capable of handling 400 square feet.

CADR stands for clean air delivery rate and is an important feature to consider in air purifiers. It indicates the filtered air that the unit provides.

The higher the CADR number, the more efficiently and effectively the air purifier delivers clean air.

What’s the Best Way to Deodorize Basements?

The most efficient and effective way of deodorizing your basement is using an air purifier. Air purifiers equipped with a carbon prefilter absorb and neutralize odors from mold, pets, etc.

Other than air purifiers, if you just want to get rid of foul odors in the basement, you can place bowls of baking soda or spray the floor or surfaces with a mixture of equal parts vinegar and water.

What are Some Tips for Efficiently Using Air Purifiers in Home Basements?

Here are some tips for using an air purifier in home basements:

· Consider the area coverage of the air purifier and make sure it can cater to the area you place it in

· If a foul odor is a major concern, place the air purifier near the source causing it

· To ensure that the air purifier works with maximum effectiveness, avoid placing it in corners and tight spaces

· Do not open doors and windows while the air purifier is working to let ‘fresh air’ come in, as it will bring along dust particles that the unit is trying to remove.

Final Verdict: What Is the Best Basement Air Purifier Sold Today?

Out of the many air purifiers on the market, the Storebary Air Purifier is one of the best air purifiers commercially available these days.

It has several innovative features like an auto mode, a sleep mode, a timer (2, 4, 6, and 8h), and several fan speeds for optimum user convenience.
