3 Best Air Purifiers For Large Basements

3 Best Air Purifiers For Large Basements

When I decided to put the time and effort into my basement renovation project, I knew air quality would be a significant concern for me.

My basement has always been super dusty, and the air quality has never been good enough for me to spend a good chunk of time there.

And since I have an air purifier for my room, I knew the only viable solution to my problem was to get an air purifier for my basement.

If you’re in a similar situation and are looking for an air purifier for your large basement but don’t know what model to get, I’ve got you covered.

When I bought my basement air purifier 4 months ago, I did a ton of research on the topic.

And in this article, I’ll share with you my favorite air purifiers for large basements on the market today.

But before I do that, I want to go over some of the core reasons why getting an air purifier for your basement is a good idea.

Why You Need an Air Purifier for the Basement

If you get a pen and paper and start listing all the reasons you need an air purifier for your basement, you can keep going for a while.

For me personally, there are three reasons why I bought mine, which most definitely applies to you too.

There’s A Lot of Dust in the Air

By default, basements are always super dusty, and air quality is generally very poor.

And while this is all thanks to poor ventilation, the lack of regular cleaning, and a few other reasons, there’s not much you can do about it.

And yes, you can always install a proper floor, hoover all the time, and install a ventilation system; that will cost you a fortune to do.

However, thanks to an air purifier, you can quickly make the air inside your basement free of dust flying in the air within hours.

To Eliminate Strong Odors

Over the years, there’s a high chance that your basement has developed its own unique odor without an apparent source.

That can make the eradication of the odor a challenging task.

But with the right purifier, you can quickly clear up any unpleasant odors, even if there’s no apparent source that they’re coming from.

To do that, you need an air purifier with an activated carbon filter. These filters are specially designed to eliminate the odors present in the air.

While such a filter won’t give a lovely scent to the smell of the air, it will make it neutral, which is what we all want anyway.

Create a Generally Healthier Space

The basement is usually the go-to option whenever you build or create a hang-out space at home.

People barely use this space in the house aside for storage, which means that you can quickly clear it out and transform the space into anything you want.

The basement could become a games room, exercise room, or a space to have a couple of drinks with friends.

However, without clean air present in the basement, you can only stay down there for so long before you want to head back up to get fresh air.

When you get a versatile air purifier and have access to purified air, the basement can quickly become an enjoyable place to spend a good few hours.

The Best Air Purifiers for Large Basements

When looking for my own air purifier for my basement, I did a ton of research.

And in the section below, I’ll go over three of my favorite air purifiers for large basements.

InvisiClean Aura II – The Best Overall Air Purifier For Large Basements

To start, I want to highlight my favorite option on the market, which is also the model I use in my basement, the InvisiClean Aura II.

The first reason I chose this air purifier was pure because of its air purification capacity.

Like most of you reading this article, I have a fairly large basement, so I need a powerful air purifier to clean the air within my ample space.

This InvisiClean model can handle areas up to 1,276 square feet, which is more than enough for most large basements.

Another excellent feature I liked in this model is its advanced filtration system.

This model features an H13 HEPA filter, an activated carbon filter, an ionizer, and UV-C light.

It quite literally has everything you could possibly need from an air purifier.

This unit can remove not only 99.97% of all solid particles as small as 0.3 microns but also remove odors, gasses, and VOCs in the air.

One downside to this unit is the ionizer, which I never recommend. 

Still, you can turn it off and use the unit as intended.

Another benefit of this air purifier is that it’s relatively quiet, even in the strongest setting.

This is particularly beneficial as I don’t like when the air purifier is too loud because it can quickly get distracting.

And if you want the air purifier to get even quieter, you can put it on whisper mode.


  • Has an H13 HEPA filter
  • Has a carbon-activated filter
  • Utilizes UV-C light
  • Very quiet operation
  • Ideal for large basements


  • Has an ionizer (but you can turn it off)

Pure Enrichment® PureZone™ Elite – The Best Budget Air Purifier

Not everyone can splash out on an expensive air purifier for their basement.

If that sounds like you, I’ve got just the perfect model for you.

Please let me introduce you to the Pure Enrichment PureZone Elite air purifier.

Like my favorite pick from above, this unit has a multi-stage filtration system featuring a HEPA filter, UV-C light, and a carbon-activated filter.

In order words, 99.97% of solid particles as small as 0.3 microns can be removed while effectively removing odors, VOCs, and other gasses.

And while this model has an ionizer, it’s best not to use this feature if you want to maintain the highest safety levels possible.

This air purifier also has a smart air quality monitor.

This feature allowed you to view the quality of air currently present in the basement.

Also, your air purifier will adjust its settings automatically based on the quality of air in the basement.

In terms of this unit’s downsides, it only covers an area of 190 square feet, which isn’t ideal if you have an extra large basement.

It also has a set dBA rating of 60, which is quite loud compared to other quieter models.

After all, this is a budget-friendly pick, so I certainly can’t complain about these minor flaws.


  • Very easy to use
  • Has a smart air quality monitor
  • Great value for the money
  • 4-stage filtration system
  • Easy to move around


  • Has an ionizer
  • Not the best option for huge basements

TruSens Smart Wi-Fi Air Purifier – The Best Premium Air Purifier For Large Basements

Since I highlighted what is probably the best affordable air purifier on the market, it’s time to look at the other side of the spectrum.

If you want to spend a fair amount of money on one of the best air purifiers on the market, the TruSens Smart Wi-Fi air purifier is a great choice.

To start, this is a smart air purifier.

It can connect to your phone and other smart devices via Wi-Fi.

That way, you can tweak and adjust the unit’s settings remotely.

So, if you have smart speakers like Alexa at home, this air purifier is compatible.

In terms of its filtration system, this model is very capable.

For one, it can capture and destroy pollutants in 360 degrees thanks to its HEPA filter, carbon-activated filter, and UV-C light.

This unit can take care of everything from allergens and airborne viruses to cooking odors and pet dander.

What I particularly like about this unit is that it doesn’t have an ionizer.

While you can turn the ionizer off in the other two air purifiers on this list, it would be much more convenient if the air purifiers didn’t have the feature.

But that isn’t the only reason this air purifier stands out.

Another benefit of this air purifier is its automatic mode.

With the automatic mode, you can leave the air purifier on 24/7, and it will automatically adjust its settings depending on the air quality in your basement.

This air purifier also has a very modern and premium design, which could be what you need if you aren’t a fan of the classic tower-style air purifier.

That said, there is one flaw with this air purifier, and that’s the fact that it’s pretty expensive.

This is the priciest air purifier on this list, but rest assured that you get what you pay for.


  • A true premium air purifier
  • Comes with an automatic mode
  • Connects to other smart devices via Wi-Fi
  • Great for large and small spaces
  • Modern design


  • Quite pricey

Features Your Basement Air Purifier Needs to Have

When shopping for an air purifier for your basement, you want to ensure it has all the right features and functionalities.

And in the section below, I’ll outline what I think is important for your basement air purifier to have for it to do its job correctly.

A True HEPA Filter

The first and most important feature your basement air purifier should have is a true HEPA filter.

An air purifier without a HEPA filter is not worth it because it won’t be able to capture all the small solid particles floating around in the air.

This type of filtration system is made of fiberglass threads that form a fine mesh to capture tiny particles as small as 0.3 microns.

These particles include PM 2.5, dust, pollen, and other irritants that can be found floating in the air.

These are coincidentally the particles that affect our respiratory systems and can trigger asthma attacks.

So, buying an air purifier for your basement must have a true HEPA filter installed.

A Carbon Filter

When shopping for an air purifier for your basement, you must also ensure it features a carbon filter.

This filter is designed to purify the air and free it from odors, smelly gasses, and VOCs.

Without this filter, though you’ll get purified air in your basement, that lingering basement smell will still be present.

Automatic Features

In most cases, automatic modes on air purifiers are pretty unnecessary.

But this could be a handy feature if you plan on putting one in a large basement.

With an automatic air purifier, you won’t have to worry about adjusting the settings all the time.

Instead, these air purifiers use sensors to detect the air quality in the room and automatically adjust their settings accordingly.

With this feature, you can rest assured that the air in your basement is as purified as possible without the unit working harder than it should.

Quiet Operation

As a person with sensitive ears, I can’t stand the loud humming sounds some air purifiers produce.

So, if you’re someone like me, I highly suggest getting an air purifier with a relatively low noise output.

This feature allows you to hang out with friends and family in the basement while leaving the air purifier on without it being distracting.

I have an air purifier noise level guide that explains how loud your air purifier should be.

So, before you invest your hard-earned money into a unit, do make sure to check out my guide first.

UV-C Light

This last feature is optional, but it would still be nice.

Most air purifiers rely solely on filtration to clean the air.

While this is great, some people would want more robust protection in the basement.

In that case, getting an air purifier with UV-C lights would be an excellent investment.

UV-C lights can eliminate bacteria and contaminants in the air, making for a much cleaner and safer basement.


It’s not uncommon for the basement to be the most stuffy room in your house.

After all, the lack of regular cleaning and proper flooring combined with adequate ventilation can contribute to low air quality.

Thankfully, air purifiers exist, and by getting a suitable model, you can take care of the quality of air inside your basement without spending a fortune.

Above, I shared my top 3 favorite air purifiers for large basements.

And honestly, no matter which model you go for, you can’t go wrong with them.
