The Alen BreatheSmart FLEX is a newer model made by the Alen company. It is designed for rooms up to 700 sq. ft., but it will perfectly fit in a slightly larger basement. A reliable, long-lasting, highly effective, and FLEX is a definite choice and my top recommendation for purchase.

Top Benefits of Using a Basement Air Purifier

As the basement is one of the rooms where you like to spend time, but it’s, at the same, a bed of bacteria, stagnant air, and air pollutants, the air purifier is a device you inevitably must-have.

Air purifiers for basements are highly efficient, and they help you remove unpleasant odors or other toxic components from the air like the following ones.

Radon

Radon is highly toxic, and it is highly recommended not to breathe air full of radon. This is a radioactive gas that comes to your basement from the soil. Breathing radon may lead to lung cancer.

Mold

Every basement has more or less mold. Mold is not really that dangerous, but it creates bad air, and some people may have allergic reactions to it.

VOCs

VOCs are dangerous, and if you have these gasses in your basement, you need to get rid of them promptly. VOCs can be put in the same category as radon. Because of no ventilation in most basements, VOC levels can be very high and, in that way, very unhealthy.

Dust

Dust is a problem in the whole house. Maybe the basement dust is not visible, but I assure you it is present. The good news is that air purifiers are best at removing dust from the air.

Musty Air

Musty air is just a symptom of the previously mentioned problems, which an air purifier can remove without a problem. If you remove dust, VOCs, radon, and mold from the air, the air will no longer be musty. 

Having previously described the isolated situations where an air purifier has helped, that’s not all; people use a basement for different purposes, so different situations have different benefits when using an air purifier.

Air Purifier Technology Used in Basements

HEPA Filters

HEPA filters, especially True HEPA filters, are capable of removing 99.97% of air pollution. It can remove almost all particles down to 0.3 microns. The True HEPA filter is an ideal choice to trap mold spores and, in such a way, prevent mold growth.

HEPA filters need to be replaced regularly for best performance. HEPA filters cannot remove gasses, bad smells, and terrible odors; for that, you will need to use a combination with a carbon filter or an ionizer.

Carbon Filters

Carbon filters are essential for basement air filtration. Carbon filters are an ideal choice to remove bad smells and odors. VOCs, gasses, and other harmful components can be removed with these filters.

Suppose you have a basement with a lousy odor. In that case, I can highly recommend picking an excellent large air purifier with an enormous carbon filter.

Ionizers

Ionizers are also an exciting choice to combat bad smells and terrible odors. They release negative ions into the air, eliminating components that create lousy air in the basement. Ionizers are fast at removing bad odors and will for sure help you keep the air fresh in a cellar.

However, you need to know that some ionizers release small amounts of ozone which is not a problem if an air purifier is certified.

Unfortunately, there are air purifiers on the market that use ionizers but are not certified, and you can not know how much ozone is released into the air. I can only suggest being careful with such uncertified air purifiers.

UV-C Light

UV light can kill germs and mold. Since it kills mold, it is a pretty good choice to combat mold in a basement. Many air purifiers today combine this option in the filtration system. In combination with an ionizer or True HEPA filter, mold will be gone in no time.

An Air Purifier Is Needed More Than Dehumidifier in the Basement

Although it would be ideal to have both of these in your basement, a dehumidifier that removes moisture particles from the air, and an air purifier whose efficiency is 99.97% in combating most airborne pollutants such as mold spores, dust, pet dander, and other contaminants.

As the role of the air purifier in removing unwanted contaminants from the air is multiple if your budget is limited and you have to opt for only one, then go for an air purifier. 

A combination of an air purifier with a dehumidifier is not always the best option. It is better to use these two devices separately. I have tested an air purifier and a dehumidifier combo and didn’t get great results.

How Effective Were the Air Purifiers I Tested in the Basement?

Stale and not-so-good air in the basement is a bigger problem than it seems, so it may be that one solution is not always enough. I can confirm that air purifiers definitely work. They are an excellent choice to combat bad and hampered air in the basement.

I have carried out tests in several different basement rooms, different uses, and different levels of air pollution. For example, during winter preparation, I switched on an air purifier in the basement that quickly removed the strong smell of vegetables and neutralized the air completely.

Another basement, which is not fully finished (unfinished basement), is used as a gym room and has a fragrant smell. I also installed an air purifier and achieved a fantastic result. I would not comment much here; I will just say that breathing was several times easier and that such an unfinished basement has found its purpose, after all, thanks to the air purifier.

Tips On How to Choose Best Air Purifier for a Basement

Before I move on to the main things you need to think about before buying an air purifier, it’s worth mentioning that installing a ventilation system in the basement helps improve airflow and remove odors

Aside from the ventilation, the air purifier will enhance air quality and eliminate impurities that cannot be expelled through built-in ventilation

All things considered, these are the things to keep in mind when choosing the best air purifier for a basement.

  • Air Contaminants. Depending on what is most prevalent in the air of your basement, for instance, things like bacteria, viruses, VOCs, mold spores, dust, and other airborne pollutants, you will need 
  • Room Coverage. Be sure you have an air purifier that will cover and successfully clean the air in a room of such dimensions in the proper time. 
  • Air Flow. Considering the CADR and how long an air purifier will filter the air in a basement
  • Filtration Technology. 
  • Brand Trustworthy.  
  • Ultraviolet Light

The most effective against the basement air is Alen BreatheSmart FLEX, which also showed excellent performances in tests I perform, so it is my absolute buying recommendation and the best choice for shopping.

Top Benefits of Using a Basement Air Purifier

If you are still not sure whether you need an air purifier and if you have asked yourself many times, “why should I use an air purifier for my basement?” then you are in the right place.

Everyone is probably wondering what benefits you can get if you buy an air purifier for the basement. All I can say is many. You can remove unpleasant odors, or you can clean the air from toxic components such as:

Radon

Radon is highly toxic, and it is highly recommended not to breathe air full of radon. This is a radioactive gas that comes to your basement from the soil.  

Breathing radon may lead to lung cancer.

Mold

I have already mentioned mold several times in this article, but every basement has more or less mold. Mold is not really that dangerous, but it creates bad air, and some people may have allergic reactions to mold.

VOCs

VOCs are dangerous, and if you have these gases in your basement, you need to quickly remove them. VOCs can be put in the same category as radon. Because of no ventilation in most basements, VOC levels can be very high and, in that way, very unhealthy.

Dust

Dust is a problem in the whole house. Maybe the basement dust is not visible in the air, but I can assure you it is present. The good news is that air purifiers are best at removing dust from the air.

Musty Air

Musty air is just a symptom of the previously mentioned problems, which an air purifier can remove without a problem. If you remove dust, VOCs, radon, and mold from the air, the air will no longer be musty. 

Having previously described the isolated situations where an air purifier has helped, that’s not all; people use a basement for different purposes, so different situations have different benefits when using an air purifier.

Tips On Using an Air Purifier in a Basement

Air purifiers can fix almost all air-related problems. They are simple to use and are very effective against bacteria, viruses, VOCs, mold spores, dust, and other airborne pollutants.

But before using an air purifier, it is recommended to do some things to get your basement in order. As I previously said, you can install ventilation which can help with airflow and remove bad odor. 

All basements have moisture issues, and for that, it is recommended to use dehumidifiers that can keep humidity levels at optimal range. If there is high humidity, mold can grow, and you will probably have mold problems. 

Existing mold needs to be removed; you can clean it yourself or hire a mold expert. If you are not sure about mold type, hire a mold expert because some mold types are hazardous if you inhale their spores.

Radon is problematic to remove, but it is also rarely an issue in a basement. To start, it is best to monitor radon levels with the test kit. In case radon levels are high, it is highly recommended to hire an expert.

Choosing the right size air purifier

The Alen BreatheSmart FLEX is my absolute recommendation and the best choice for shopping. It is designed for spaces up to 700 sq. ft. It will also suit larger basement spaces. In addition to this model, I have added some other models to the list, designed for different sized basements, to help all potential customers to choose the suitable device for their needs as quickly as possible.

Do you need an air purifier or dehumidifier for your basement?

Combining an air purifier and a dehumidifier is not always the best option because it is challenging to make a perfect product for both purposes. I have tested some devices that are a combination of an air purifier and a dehumidifier (which you can find on the Air Purifier First website) and didn’t get great results. It is better to use these two types of devices separately.

A dehumidifier alone prevents mold from forming in the basement. An air purifier is a great addition to clean and freshen the air. 

Air Purifier Vs. Dehumidifier for Basements

An air purifier is focused on removing airborne pollutants such as mold spores, dust, pet dander, and other contaminants.

A dehumidifier is not removing lots of airborne pollution. Dehumidifiers have filters also, but their purpose is to remove extensive pollution that may cause trouble to the dehumidifier. The primary purpose of the dehumidifier is to remove excess moisture from the basement.

Because of different purposes, it is best to use both devices in a basement and cover all bases.

FAQ

Should I use an air purifier in my basement?

Yes, an air purifier is an excellent device for a basement. It can improve the air quality and remove harmful particles found in such a room.

Will an air purifier help with the basement smell?

Yes! Suppose the air purifier contains a True HEPA filter and a premium carbon filter. In that case, it will purify and freshen the air in your basement.

Do air purifiers really work for mold?

Yes, an air purifier can help with reducing mold spores from the air. Although, if your basement is too moldy, it’s more likely that you will need to replace filters more often.

Conclusion

The air quality in a basement is generally not the best. It can significantly impact your health, especially if you are allergic to dust and mold particles that you find in the air. Therefore, you need to prevent inhaling all the harmful particles from the air by buying an air purifier for the basement, and the best one for this purpose, that I have tested, is definitely Alen BreatheSmart FLEX
