Best Air Purifier for Basement | Comparison of Top 5 Air Purifiers

A basement is a number of things for many people. Few people never go in there until they need to find an old bike, an antique chair, an old tools box or even some old furniture. In contrary, a basement is a part of daily life for some; they go in there every day for one reason or another.

Some people even set it up as an extra room for a member of the family, guests or for when the wife kicks the husband out of the bedroom. Whatever the case, there is a need to take care of your basement.

Caring for your basement requires cleaning the floors, walls, furniture, and most importantly, the air. It is very likely there’s not much ventilation in your basement due to its location and lack of sufficient openings.

This is why you need something like an air purifier to help change the air and keep it fresh all the time. Furthermore, mold, dust, germs and pollen are likely to be flying around your basement.

An air purifier for the basement will help you take care of those and the dampy smell you perceive every time you go there.

Choosing the best air purifier for your basement can be quite a hassle. If you’re reading this post, we assume you’ve been searching for answers.

Here, we’ll not just recommend what we consider the top 5 air purifiers for basement, we’ll also provide the necessary factors you should consider before you make a choice.

Top Air Purifiers for Basement: By Best Performing Feature

Buyer’s Guide: Critical Factors to Consider to Select a Perfect Air Purifier for Basement

A basement is a sensitive spot to clean with an air purifier because it presents the three major forms of air contaminants; particles, germs and odors.

Therefore, you shouldn’t be looking for a specific filter, but a combination of appropriate filters to take care of your basement air.

Also, the noise level may not exactly be a factor, especially if no one is sleeping in the basement. Just be sure it’s not too loud that it disturbs the entire house. Here are things you should look out for;

1. Type of Filter

True HEPA Filter:

More than 80% of all air purifiers use the HEPA filter. However, what makes the difference is the “True” status.

Look out for a True HEPA filter capable of eliminating particles as tiny as 0.3 microns. This means you won’t have to worry about large and microscopic particles floating in your basement. 

Carbon Filter:

While the True HEPA filter can take care of particles, it is helpless in the face of odor, smells and VOCs.

This is why you will also need an air purifier for basement that has an Activated Carbon Filter to take care of that horrible smell emanating from your basement. It is not unlikely for rodents to die in your basement. We all know how that smell can be.

UV-C Light

All across the world, there are concerns about UV-C and its safety for humans. Truth is, UV-C is, perhaps, the only type of air purifier filter that can eliminate germs, viruses and bacteria in your basement.

Some manufacturers include this feature in a way that is harmless to humans. Whatever the case, it won’t be such a bad idea if there’ll be no one living in the basement.

2. Size

Size is also a factor of the essence. Is there space in your basement for a large air purifier? Will you place it on a table or on the floor? Will it obstruct the movement of people and pets?

We always advise that you check how much space you have before you select a device for your basement.

3. Coverage

Next to size is coverage. Coverage has to do with how much area the air purifier is designed to clean.

To be sure, calculate your basement area by multiplying the length and the breadth. The result is measured in square feet. For instance, if your basement is 27″ x 18″, the area will be 486 square feet.

This means that the air purifier you should choose for that basement must have a coverage larger than 486 square feet.

4. Price

Price is the most important factor for many consumers. Ideally, it shouldn’t be; but purchasing power and the worsening economic situation around the world makes it an inevitable condition.

If you do find an air purifier for basement that falls within your budget and offers the performance and value you desire, then you should pick it up by all means.

However, you should never settle for a poorly made air purifier because of a budget. You’ll end up spending more than you should’ve because you’ll end up replacing it in a matter of weeks or a few months, or change the filters every other week.
