Using the internet, we discovered how many possibilities are there. Even we got lost: the competition is tough. So, we laid out criteria to choose the best basement air purifier. The criteria were fairly simple: get the most bang for a buck, have great performance and user reviews.


It's been a while since I've looked at the reviews in this section. I had to focus my search for the best basement air purifier down to a very specific set of criteria. As far as I could tell, it needed to be able to handle big spaces, as well as particular cellar contaminants and the strong scents typical of musty basements. The task at hand is a daunting one!

It's not uncommon for even the tidiest cellar to contain ten times as many contaminants as the rest of the home.

There is no place in your house where the air is more contaminated than in the basement. Those of you who have a basement know the stench all too well.

Buying Guide

If you want to improve the air quality in your basement, you need not just look for Energy Star-certified air purifiers or air cleaners, but you should also be especially cautious for a few of reasons. Having a huge purifier in the basement is necessary because it won't be examined as frequently as the rest of the house.

Here are the most crucial considerations to keep in mind while searching for a basement air purifier.

Carbon use

For high-volume chemical elimination and purification, you'll need a lot of activated carbon, therefore make sure your purifier is large enough to hold a lot of carbon. In order to be effective, MCS air purifiers must be too tiny.

When using activated carbon, make sure you know the difference between activated carbon that has been treated and active carbon that has not.

Finally, because powerful air purifiers typically use treated activated carbon, you may expect that if you buy one for your basement, it will most likely do so. It is common for activated carbon to be treated with additional additions to enhance its ability to adsorb or react with substances. To keep it running smoothly, a washable carbon filter is included.

If you're only going to use the air purifier in the basement, you won't have to worry about the additives being detected. It's helpful to have a basic understanding of how air purifiers, such as those with HEPA and carbon filters, work in order to better appreciate how they impact performance and airflow.

Available space and coverage area

Air purifiers are known for their size and coverage area, but the most important thing is to strike the right balance between the two. A little air purifier won't be able to filter your basement's stale air, making it essentially useless.

You should also verify the air purifier's Clean Air Delivery Rate (CADR). Aim for a CADR of two-thirds of the room's square footage when shopping for an air purifier. The Clean Air Delivery Rate should be 80 if the room in question is 120 square feet.


Your air purifier should be composed of metals or at the at least, high-quality polymers to ensure that it is effective. The air purifier may not be able to purify the air if it leaks gases and airborne pollutants.

In order to avoid off-gassing and defying the purpose of a purifier for basement use, avoid units that contain fiberglass or glues.

Filtration System

In order to remove the stink from the basement, you need use an air purifier with a HEPA and activated carbon filter that can remove the dust and dandruff as well as the odor.

Noise Level

A quiet air purifier may not be necessary if your basement is mostly used as a storage area, but if it is utilized as an entertainment room or a bedroom, it should be.

Choosing an air purifier with a noise level of 20 to 30 dB is advised, as it allows for silent operation. You won't be bothered by this level of noise, which is the equivalent of whispering.

Filtration stages

You'll want to verify the air purifier's filtering stages after you've figured out the optimum CADR for your basement. Consider the fact that air purifiers come in a variety of filtering technologies, which can affect how effectively they can trap mold spores.

A basement air purifier should be outfitted with the following filters:

A HEPA filter that is truly HEPA-compliant. Up to 99.97% of all airborne particles can be removed with High-Efficiency Particulate Air (HEPA) filters. 0.3 microns in diameter can also be trapped by it. You can remove mold spores from the air in your basement by using this filter.

Carbon filtration. Mold spores and other irritants can cause unpleasant scents, but this filter can help. You can use it to purify the air while also providing a mold trap.

A charcoal filter that is activated. Activated charcoal, like carbon filters, removes unpleasant odors and gasses from your basement like carbon filters. Impurities and allergies are able to be trapped by the material's natural properties.

Filters for ultraviolet radiation. In order to remove viruses and germs from the air, this filter is used. In hospitals and laboratories, it's a common way to keep things clean.

In addition to the ones listed above, several other types of filters can be found in modern air purifiers. In order to enhance the performance of their air purifiers, many manufacturers employ patented filtration techniques.

Choose a filter that's easy to replace, and make sure it's readily available to you. There is no need to purchase a new air purifier as a result.

No-OZONE Certification

Look for ozone-free air purifiers whenever possible. The long-term exposure to ozone can lead to major health issues.

In the past, air purifiers used ozone to destroy germs and viruses, but this method has been phased out. Side effects have been reported by users, despite the fact that it is quite effective.

Manufacturers of air purifiers have shifted to ultraviolet technology to meet the need for a safer option. It is effective at destroying airborne germs without generating ozone.

With or without remote controls

Remote-controlled and manual air purifiers are also available. A remote-powered model is more handy for basement use, but both are fine. A lot of time is wasted going back and forth in your basement only to adjust your airspeed or turn off the unit.

Price and warranty

Finally, you should take into account the unit's cost and warranty before making a purchase.

To get the best results, I recommend buying a high-end air purifier for your basement. Make sure that it has a good guarantee in case of manufacturing issues.


Why is mold found in basements?

When there is a lot of moisture in the air, mold tends to thrive. Because a basement is located at the bottom of the house, it is prone to flooding due to strong rains, broken pipes, or any other cause. When it's cold outdoors, condensation can build up in a basement because of the humidity. Basements, particularly large basements, are prime breeding grounds for mold because of all of this. It is because of this that basements are the best location to place your air filter, air conditioner, or air purifier.

Should I leave the basement air purifier running at all times?

The quality of the air in your basement has a lot to do with this, therefore there isn't a definitive solution. Having no windows in your basement increases the likelihood of it becoming a breeding ground for mold.

Using it for anything would need leaving it on all the time in order to avoid waiting for it to start working and provide fresh air.

Should I put an air purifier in my basement?

YESSSSSSS! Your basement's air quality will improve greatly if you use an air purifier. Lower ground level dust and hazardous particles can be filtered.

Will an air purifier help with basement smell?

YES! Basements benefit greatly from the installation of an air purifier. The air purifier removes mildew, dust, and other contaminants from the cellar's air, enhancing its quality. Air purifiers with activated carbon filters are available if your basement smells musty or wet. Odor-absorbing activated carbon filters are available.

How Can You Improve The Air Quality In A Basement?

Installing a high-quality air purifier in a basement is a simple way to improve the quality of the air there. All of the toxins and odors that basements produce are precisely addressed by these systems, which are built to do so.

In many cases, basements are plagued by dampness and excessive moisture in the air. In the event that this is the case, you can support your air purifier by purchasing a dehumidifier and enabling the two machines to function together.

Keeping your basement's air quality high is as simple as keeping it clean and washing any furniture on a regular basis.


Hopefully, you've been able to figure out which of the air purifiers listed here is the ideal one for your basement, or at least reduce it down to two. If you've forgotten, here's a refresher:

Overall, the Alen BreatheSmart is the greatest air purifier in terms of its coverage area, its ionizing technology, and the effectiveness of its filter set. There are four different types of filters available so you may get the exact air quality you want.

The AeraMax 300 is the greatest air purifier for a wide range of applications. It can cover up to 600 square feet and has a clever sensor that adjusts the fan's speed based on the room's temperature.

When it comes to air purification, the SilverOnyx has five stages of filtration, including carbon and HEPA filters. Mold spores and pet dander can be eliminated from any size area thanks to its ability to employ UV light to purify the air.
