How to improve basement air quality

There is no one-step solution for purifying basement air and keeping it fresh. Instead, several factors have to be taken care of.

Treating the symptoms

Air purifiers: A quality HEPA filtered air purifier will remove impurities such as mites, mold spores, and even odors from the air. We will review some of the best basement air purifiers in the next section, but before we get there, we will first discuss what caused the air to become polluted in the first place.

Dehumidifiers: Basements are hot and humid, which is extremely bad because it fuels mold growth. To make matters worse, most basements do not have any windows, so there is no way to let fresh air in. The easiest way to control such humidity is with a dehumidifier. Not only will it remove all that excess moisture from the air, but it will also significantly reduce mold, which in turn helps keep the air clean and breathable.

Treating the causes

Mold Removal: Removing mold from your basement is crucial. Find out how to safely and effectively do so here.

Regular cleaning: Many people neglect their basements when it comes to cleaning. The truth is that your basement needs just as much attention as the other parts of your home.

Sump pumps: Water leads to mold growth and humidity, so if your basement floods from time to time, or if there is water seeping through the walls from the soil outside, then you may want to invest in a sump pump.

Ventilation system: Air impurities thrive in stagnant air, and as previously mentioned, most basements do not have windows. Luckily, there are several options you have when it comes to choosing a ventilation system that is ideal for your basement.


What to look for in a basement air purifier

The amount of air purifiers available today is staggering, so how will you know which one is ideal for your basement? Here are some things to consider when choosing one.

Hepa filters: Hepa filters in your air purifier are essential, and without them, you are just wasting your time and money. That’s because air impurities such as mold spores and mites are microscopically small, and only HEPA filters are capable of catching and removing them from the air.

Carbon filters: If your basement has a stench, then carbon filters are another essential feature you will need.

Coverage area: Coverage area is a crucial factor you will have to consider because there is no point in getting an air purifier that can purify a maximum of 200 square feet for your 500 square feet basement.

Energy efficiency: Energy efficiency is crucial since you will be running the system for most of the day, if not 24/7. After all, the last thing you want is high energy bills at the end of each month. This shouldn’t be of too much concern nowadays since most modern air purification systems available today use very little energy – even when running 24/7.

Medify MA-40 medical-grade air purifier

Medify MA-40 medical-grade air purifier

The sleek and super-modern looking Medify MA-40 medical-grade air purifier has the incredible ability to capture and remove 99.97% of all air impurities – which is why it’s fit for use in hospitals.

What’s most impressive about this air purifier is how fast it works. It cleans 99.97% of all airborne contaminants in a 400 square feet space in 15 minutes, an 800 square feet space in 30 minutes, and a 1,300 square feet space in an hour.

Indicator lights will show how contaminated the indoor air is. A red color means it’s heavily polluted, and the blue light indicates that it is clean.

Its 4-stage filtration process is astounding and is the reason why it’s one of the best air purifiers on the market today.

The pre-filter removes larger particles such as dust and pet dander. An H13 HEPA filter traps microscopically small contaminants down to 0,3 microns in size, such as mold spores, mites, etc. The carbon filter eliminates any smells and odors that may be lurking in the basement, and the anion generator releases negative ions into the air, which gives the room that fresh air feel.

The filters need to be replaced every six months or after every 3,000 hours of use. Replacing them at the correct time is of particular importance because as long as you abide by those recommendations, the product will have a lifetime warranty.

There are also three speed settings – low, medium, and high. And it’s even quiet enough to sleep in the same room while it’s running while on the high setting.

It also has a child-lock feature and an automatic timer that can be set for 1, 2, 4, or 8 hours.

Alen BreatheSmart FLEX air purifier

Alen BreatheSmart FLEX air purifier

The Alen BreatheSmart FLEX air purifier with its sleek and modern design looks good in bedrooms, living spaces, kitchens, basements, and even office spaces.

What’s truly spectacular about this air purifying system is its ability to clean the air in a 700 square feet space in just under 30 minutes.

It’s also the quietest basement air purifier on the list, thanks to WhisperMax Technology that creates a 20hz pink noise frequency. There are 4-speed settings. Setting 1 puts out an impressive 39dB. Speed setting 2 puts out 42dB, which is comparable to light rainfall. Speed setting 3 is at 49dB, and that is almost the same as heavy rainfall, while turbo speed is at 55dB.

The air purifier also has a multiple filtration system that removes particles such as mold spores, bacteria, and even influenza from the air, as well as any unpleasant odors.

Also, if you choose this air purifier for your basement, you can run it 24/7 without having to worry about your electric bill. That’s because it uses a mere 36 watts on its highest setting (turbo) – and on its lowest setting, it will add only 50 cents to your power bill.

SilverOnyx air purifier

SilverOnyx air purifier

The SilverOnyx air purifier shares a lot of the same features as the aforementioned Medify MA-40. The only real difference is that the SilverOnyx has an additional filter (5) and is capable of cleaning a smaller space (a maximum of 500 square feet).

The system has a pre-filter for capturing larger particles, an H13 HEPA filter for small contaminants up to 0,3 microns in size, a carbon filter for odors and smells, and a clean air ionizer filter for creating that fresh air feel.

The fifth filter (which sets it apart from the MA-40) is a UV light that instantly kills bacteria, viruses, and mold spores.

Additional features include relatively quiet 5-speed settings, an on/off timer, an auto mode, sleep mode, and a light indicator that notifies you whenever it is time to replace the filters.

All in all, it’s an excellent system and is ideal for basements not exceeding 500 square meters.

The Hathaspace Smart True HEPA air purifier

Hathaspace Smart True HEPA air purifier

The Hathaspace Smart True HEPA air purifier is the best budget basement air purifier on this list, but that does not mean that it compromises on quality or features.

Firstly, the system has a 5 step purification process that removes 99.97% of airborne contaminants.

The first filter is known as a Nano Cold Catalyst filter and is a pre-filter that also takes care of toxic household chemicals. An activated carbon filter to remove odors and volatile organic compounds (VOC’s). The anti-bacterial filter traps and removes bacteria and viruses and a true HEPA filter for removing particles such as mold spores. The final line of defense is an ionizer that releases negative ions and gives the basement that fresh air feel.

Everything sounds great so far, but it can only clean an area of up to 350 square feet. So if your basement is bigger than this, you may want to look at the other options listed above.

Nevertheless, it also comes with an auto mode, remote control, and a convenient feature known as an air quality sensor. This air quality sensor displays your current air quality and even goes as far as automatically adjusting its fan speed, depending on how contaminated your indoor air is.

The product is whisper quiet and comes with a 2-year warranty.
