This black air purifier measures 8.3 x 14.75 x 25 inches and weighs 18.25 pounds. While it has feet, there are no wheels. It comes with 3 stages of air filtration. The first is a pre-filter followed by a medical-grade H13 HEPA filter.
The final stage is an activated carbon filter. It captures 99.97% of particles as small as 0.3 microns.

For a 258 sq. ft. room, it will perform 4.8 clean air cycles per hour. There are 5 fan speeds, controlled by a dial on the top of the purifier.
On the lowest fan speed, the air cleaner is whisper quiet. The automated CirQulate System is a smart sensor that monitors air quality and automatically adjusts the fan. The fan speed can be seen on the digital display. The digital display also warns you when the filters need changing.
You can see the indoor air quality on the color-coded bar. A blue light means good air quality, orange moderate, and red poor. For animal lovers, every purchase supports the Bissell Pet Foundation. There is a 3-year limited warranty with the Bissell air purifier.

Many people are now looking for appliances that can be controlled the smart way. The same applies to basement air purifiers. Be careful not to confuse this model (the Smart LV-PUR131S) with the cheaper LV-PUR131 which is the same version but without the wireless connection.
This white purifier is 7.2 x 14.6 x 18.5 inches and weighs 11.24 pounds. With the 2.4GHz wireless connection, you can download the Levoit app to monitor air quality and adjust the settings. If you have Alexa, you can control this air purifier with your voice too.

Because the clean air is expelled from all around the sides, you need to keep this away from the basement walls. It looks stylish in black or white and there are some small savings if you buy the pack of 2.
The air filtration is the same 3-stage filtration as many of the Levoit purifiers. There is a pre-filter for larger particles, and H13 true HEPA filter for particles as small as 0.3 microns, and a carbon filter that is high efficiency and activated.

We finish off our list with Rabbit Air purifier with a price tag that may shock you but is by far one of the best air purifiers for mold and your basement. The air purifier is 20 x 21 x 7 inches and can stand alone or be mounted on the wall.
You can choose a panel design such as a Van Gogh or Snoopy image. The pre-filter and carbon filter (activated) we have seen before. But this purifier has an additional medium filter, BioGS HEPA filter, and a customized filter. Finally, a brushless direct current motor pushes air to the negative ion generator.
The BioGS HEPA filter is more advanced than a true HEPA air purifier because it captures 99.97% of particles as small as 0.3 microns and over 99% of particles of less than 0.1 microns. The filter not only reduces airborne mold spores but also reduces the growth of bacteria and viruses on the filter.
There’s more. There are 4 options for customized air filters. You can choose from a toxin absorber, odor remover, pet allergy, or germ defense filter. The germ defense filter works to capture more airborne particles, bacteria, viruses, and mold spores.
The clean air delivery rates are also impressive. The air purifier has a CADR of 180 CFM for smoke, 193 CFM for dust, and 200 CFM for pollen. And that is with 2 air cleans in one hour.
The control panel lets you adjust the fan speed, auto or pollen mode, sleep mode, and the option to switch off the negative ions. You can also see the filter replacement light and odor sensor. There is a light sensor that automatically switches the purifier to sleep mode when the room starts to get dark.
There is a remote control too. Yes, this air purifier is the most expensive, even as much as 5 times the price of the cheaper air cleaners. Nevertheless, it comes with a 5-year warranty and is exceptionally well built.
With an average use of 12 hours a day, the filters can last up to 2 years. This makes it extremely cost-effective compared with filters that need changing at least every 6 months.
- High-quality parts, even those that can’t be seen
- The odor sensor is very sensitive
- Fantastic indoor air quality whether it’s your basement air or kitchen
- It might be a little too much as a basement air purifier for some
What is an Air Purifier for mold?
An air purifier for mold will capture harmful mold spores by filtering airborne particles, trapping the spores, and killing them.
Some of the best air purifiers use ultraviolet light or activated carbon filters, or they will be HEPA air purifiers. The best air purifiers will improve indoor air quality and the basement smell.
Why buy an Air Purifier for mold?
Mold occurs when moisture is present. It can be from leaky pipes, condensation, or the HVAC. A basement smell could be a sign of poor air quality, or it could be the first sign of mold. While there are many types of the mold spore, Stachybotrys, or black mold, is one of the most dangerous.
There is no need to risk flu-like symptoms and respiratory problems. For your health, an air purifier for mold in the basement or other large rooms is essential.
While you might think that it is the air filters that are the most important thing, the first specification you should look at is your room size. You can buy the best air purifier on the market, and it can be completely useless if the recommended room size is 500 sq. ft. and your basement is 800 sq. ft.
The effectiveness of the air purifier will also depend on the location. Read the instructions on the best place to put the air purifier, especially if it is round. Anything less than 3 stages of filtration should probably be ignored.
A pre-filter is helpful, more so if it is washable because it will help the other filters to last longer. Always read and check whether your choice is a HEAP air purifier or a true HEPA air purifier. True HEPA air purifiers are more efficient and will have a greater effect on mold.
Many of the other features will depend on the individual. The size and design depend on the space you have available. The options like Wi-Fi and remote control are helpful but if you are planning to run the purifier on auto mode, these features aren’t as relevant.
We also paid close attention to the noise levels and again, this is often less relevant for a basement air purifier. With regards to price, air purifiers under $100 have one star, from $100-$200, 2 stars, between $200 and $300 have 3 stars and the one 4-star rating is currently over $500.
Understanding your needs will help you select an air purifier with the right price but don’t forget to compare replacement filter costs.
Frequently Asked Questions – FAQs
What is the difference between a carbon filter and an activated carbon filter?
Carbon filters and activated carbon filters are made of the same material but there are more pores in an activated carbon filter. Because of this, more particles and odors can be trapped in the pores, making them more efficient.
Is a higher clean air delivery rate better?
Yes, a higher clean air delivery rate means the air is cleaned in a room more quickly. Of course, this will always depend on the room size and the recommended room size of the purifier.
Are UV light basement air purifiers dangerous?
This is a debatable question and purifier brands will have different responses. UV-C filters emit varying amounts of ozone, which can harm the environment.
Germ Guardian, however, would tell you that UV-C filters are the most effective on mold spores and that they will also prevent spores from settling in the air conditioner unit.
What is TI02 treatment?
Titanium Dioxide is a treatment used with ultraviolet lights to further improve air quality. Titanium Dioxide is considered to be highly stable and harmless.
It’s almost impossible to choose the best air purifier for mold in the basement as the decision has to be based on your basement size. Levoit has a good range of purifiers, and they are priced well.
But the durability is often questionable. We do like their commitment to the environment. Despite its price tag, the Rabbit Air purifier is certainly one of our favorite air purifiers for any room in the home.
