10 Best Basement Air Purifiers in 2021: Buyer’s Guide

Basements are interesting places. Within a basement, there is a great deal of humidity – which is moisture – and there isn’t a lot of fresh air that is coming in, due to the lack of sufficient ventilation. As a result of this lack of ventilation, but abundance of humidity, mold and mildew is given free reign to grow anywhere it wants, and this easily leads to a situation where your entire basement becomes covered in nasty mold and mildew, which then leads to a wealth of other problems that affect the entirety of your home.

Before we dive into what those problems are, it’s important to understand that, while basements are spaces that are inherently flawed, in many ways, this problem does not lack a good and sufficient solution. Instead of being forced to deal with this problem, and the myriad of problems that this problem leads to, there’s a really simple and easy solution that can make this problem go away.

Owning a basement air purifier is that solution. There are a bunch of different air purifiers that are on the market, and each one of these air purifiers is designed for a different purpose that it needs to fulfill. You’ll find a lot of regular air purifiers that aren’t designed for any particular space, and then you’ll find basement air purifiers.

If you have a basement that has some nasty air, then a basement air purifier is the ideal choice, because this type of air purifier is specifically designed for the types of things that are often found in the air of a basement; namely, high humidity, as well as the mold and mildew particles that come as a result of the excess moisture.

A basement air purifier can control and level out this excess moisture, which is something that must be noted. But, along with that, a good basement air purifier can do a few other things, too. With the basement air purifier, you’re able to get rid of the different particles that are in the air of the basement, the particles that consist of things like heavy and thick dust, as well as various mold spores and different types of germs.

Mold spores, in particular, affect your basement a great deal, because these mold spores are one of the main reasons why mold and mildew form within your basement. Along with that, a good basement air purifier keeps your basement looking, and feeling, nice. There isn’t too much mold, or mildew, and the air is nice and clean, without all of the gunk that often finds its way into basements.

For some people, a basement air purifier isn’t a particularly notable, or desirable, purchase, since some people don’t use their basements that much, or they don’t use their basements for any notable or important purpose. And, while this may be the case, without a basement air purifier, your basement is easily susceptible to the growth of mold and mildew.

Air Purifier for Basement

How Does Mold And Mildew Affect The Basement?

Having mold and mildew in your basement isn’t a good thing. And, this is for a variety of different reasons. One of which is the fact that mold and mildew doesn’t smell that good; both of those things smell very damp and dirty, and the smell is far from a pleasant one. If you’re sensitive to bad smells, this is something to consider, because mold and mildew both smell terrible.

With that being said, though, the effects of mold and mildew are quite a bit more sinister than just “smelling bad”. Mold and mildew can cause a lot of damage to your health, and that is one of the biggest reasons why it is important for you to take the necessary actions to prevent the growth of mold and mildew.

If mold and mildew are growing across the wood that is in your home, this isn’t a bad thing. It’s not a good thing, either, but the wood itself isn’t being damaged, since mold doesn’t cause wood damage. But, when it comes to your health, mold does cause a decent amount of damage that can prevent you from living your day-to-day life at ease.

Air Purifier

When you’re in the basement, and you’re breathing in those mold spores, you’re actively damaging your body. These mold spores are triggering allergies, asthma, and they can lead to various respiratory problems, including respiratory infections. This is because mold spores produce various irritants, as well as allergens, and these two things are often the cause of illnesses such as the common cold, among others. None of these things are too serious, but they aren’t fun, either.

Now, if you already have a history of problems related to things like respiratory illnesses, asthma, and a general sensitivity to allergens, then this is important to note. Mold and mildew are only going to enhance the symptoms of those things, and if you spend a lot of time in the basement, you aren’t going to have a good time, at all, trying to deal with those mold spores and the nasty effects that they are producing.

But, with a good basement air purifier, you can mitigate those effects, and make the experience significantly more pleasant for yourself, and it’s going to be easier to remove the mold and mildew properly, later on.

As a side note, if you don’t use your basement that much, or aren’t particularly sensitive to mold and mildew, a basement air purifier is still a good investment, since mold and mildew are able to attach themselves to all kinds of different things, such as clothing and even food that has been put in storage.

What Does A Basement Air Purifier Do?

To answer this question, we need to run through what an air purifier is. And, an air purifier is a very simple device that is designed to take in air, the air that is found within a single space, and it takes in this air and then cleans that air, removing a bunch of different particles from the air. From this process, the air is significantly cleaner, preventing the health issues that were associated with the particles that were in the air, before it was purified, while also making the overall space smell nicer, and a lot cleaner, in general.

Most air purifiers use HEPA filtration systems. Now, the term “HEPA” stands for “High-Efficiency Particulate Air”, and this refers to a filtration system that takes in air, and then removes all of those small and nasty particles. These are the types of particles that consist of things like allergens, germs, and different types of bacteria.

Today, different air purifiers purify your air in different ways. You can find air purifiers that use the power of UV rays to do this, as well as air purifiers that use ionizer technology, among other types of technology.

So, a basement air purifier is the same thing. A basement air purifier uses one specific purification method, and this allows it to take in air from the entirety of that space, so that it is then able to remove the nasty particles from that air. When the air is done being purified, it is sent back out into the basement.

By doing this, the air purifier can remove the mold spores within the air, as well as the allergens and other types of germs and bacteria. Most of the time, the mold that is causing the majority of the health problems, is in the form of small mold spores floating throughout the air, rather than concentrated patches of mold.

Unlike the other air purifiers, basement air purifiers – which are air purifiers with a lot of extra power and capabilities that are beneficial for basements – have been designed to accommodate spaces with many similarities to basements, and the unique demands they give to an air purifier, with regards to humidity and things of that nature.

Basement Air Purifier

What Do I Need To Look For And Consider?

The process of searching for, and finding, the best basement air purifier does not need to be a difficult or complex one. Instead, it can be a very simple and very easy process, if you focus on a couple of key things that will affect the majority of your overall experience with the basement air purifier.

In this section of the guide, you’re going to learn what those key things are, and what you need to consider, with regards to how the basement air purifier will be able to purify your basement.

Air Purifier

How Much Space Can The Basement Air Purifier Purify?

Every basement air purifier has this thing known as its “Maximum Area Coverage”, and what this refers to is the maximum amount of space that the basement air purifier can purify, without you having to move it around to other parts of the space.

Some basement air purifiers have a Maximum Area Coverage of 300 square feet. Others have a Maximum Area Coverage of 1,000 square feet. In the end, it does depend on the basement air purifier that you buy.

The most important thing of all is to consider the size of your basement, and the Maximum Area Coverage that would ensure you can properly purify the entirety of that basement, without having to move the basement air purifier around that much.

As a general rule, the larger the Maximum Area Coverage, the more flexibility you have, so you aren’t going to need to worry about being ill-equipped to deal with the size of that basement, or other spaces.

The Best Basement Air Purifiers

What Are The Filtration Mechanisms That The Basement Air Purifier Uses?

As mentioned earlier in the buying guide, every basement air purifier is a little different, when it comes to the filtration mechanisms it uses. Most filtration mechanisms are quite good, but it is important to consider the mechanisms that are used, though.

If your basement air purifier has a Pre-Filter, then that’s nice. A Pre-Filter is used to get rid of the bigger particles, from the air, before the next filtration mechanism is used to remove some of those smaller particles. But, a Pre-Filter makes that process more effective, since the bigger particles are unable to hinder that process.

It’s important to have some kind of HEPA-filter in your basement air purifier. These are easily the most effective filtration mechanisms for a basement air purifier, and that’s because they are specifically designed to eradicate all kinds of different small particles, and these are the kinds of particles that will lead to the growth of mold and mildew, as well as that nasty smell.

Make sure that the filtration rate is 99%, and that it’s able to remove particles as small as 0.3 microns, because that’s a sign of a good HEPA-filter. Most mold spores are, at their smallest, two microns.

Some type of Activated Carbon Filter is a great choice, as well, and more and more air purifiers are coming with this type of filtration mechanism, so it won’t be that difficult to find. What an Activated Carbon Filter does it is using the power of activated carbon to take in all of the different odors and smells that are coming from those particles that the HEPA-Filter is removing, and then it gets rid of those nasty odors and smells, which makes your basement smell a lot better.

Basement Air Purifiers

How Mobile Is The Basement Air Purifier?

Mobility comes into play for three reasons. The first reason is that you’re going to have to take this air purifier down into the basement, and if the air purifier is heavy, or difficult to move, that isn’t going to be easy. And, it’s going to be even more difficult to take it upstairs, since you’ll be climbing up those stairs.

Mobility is also important because some of the basement air purifiers on the market aren’t capable of purifying a large space, so you’re going to need to move it from one of part of the basement, to another. If the basement air purifier is heavy, and doesn’t have wheels or some type of handle, this is going to be challenging.

In the end, when looking at basement air purifiers, make sure that it has wheels so that you can push it around, and some kind of handle, so it’ll be easier to move around.

Air Purifier Basement Guide

How Much Does The Basement Air Purifier Cost?

Finally, the last thing that you need to consider is the cost of the basement air purifier. Air purifiers of all sorts do vary, when it comes to cost, and for a relatively inexpensive, but efficient, one, you’ll probably be paying around $200. For something that has a more elaborate set of filtration mechanisms, you’re going to be paying about $400, to $600. While these are high prices, these types of air purifiers will last a long time, and you can use them to purify the air in just about any type of space, so keep that in mind.


At the end of the day, if you own a basement, and you want to keep that basement nice and clean, then you’re going to need a good basement air purifier. Fortunately, there are a lot of good ones on the market, and by following this guide, you aren’t going to have any problems finding the best basement air purifier for you!
