How Do Air Purifiers Help with Mold?
If mold has come into your home, then it isn’t just a surface issue that you can see on the floors, walls, and other places where there’s moisture. Mold spores can seep into the air and cause more problems. This is where air purifiers come in.
Air purifiers get rid of mold by doing what their name implies: purifying the air. They directly work to kill the mold spores. A black mold air purifier especially should have a quality filter that can remove the majority of microscopic particles in the air so that you know the spores are gone for good.

What Type of Air Purifier for Mold to Buy?
Air purifiers come in a variety of models. Their types depend on things like their filtration system, what they remove, and whether they’re made for home or commercial use.
Since we’re focusing on air purifiers for mold issues, you can look at a handful of different types. HEPA air filters, as we mentioned before, are good for mold seeing how effective they are at killing small particles. This type does need to be replaced more often, usually monthly.
You can also look for ultraviolet air purifiers if you have a mold issue in a smaller space since these are made compact. UV machines are able to kill around 99.9% of mold spores, but their bulbs should be replaced yearly or sooner if you use it often.
Ionic air purifiers are another we mentioned earlier that can also help with mold problems. The majority of these are large, but there are some home-sized ones you may find. They can handle most air problems except for odors.
Factors to Consider When Buying an Air Purifier for Mold
When you’re shopping for an air purification device, there are many important factors to keep in mind. These will ensure you get the right air purifier for your specific issues.
- Room Coverage
An important feature to look for in any air purifier is the amount of coverage it offers. If you have a mold issue in a large room, then it’s most ideal to get a purifier that has a wide coverage. These can be more expensive, but they ventilate spacious areas better.
There are compact units that are just as capable over a smaller area though, so if your room isn’t big, then consider purchasing these types of units instead.
- Technology
Various technologies are used inside air purifiers to determine what they can filter out and how well they can do it. As you browse these products, you’ve probably seen HEPA mentioned often.
HEPA, an acronym for “high-efficiency particulate air” filter, can remove roughly 99.9% of airborne particles such as mold and bacteria that are around 0.3 microns in size.
Such small particles are dangerous since you can inhale those easier, so if mold’s an issue, you’ll want a powerful filter that can stop them in their tracks before they reach you.
A commercial air purifier tends to have these filters, but you can easily find them in home-based air purifiers as well.
Some have additional technology like silver ion, which can be helpful for mold removal since it contains antimicrobial properties.
- Maintenance
For air cleaners to work properly, their filters have to be good, and that requires proper maintenance. Usually, the most you’ll have to do is change out the filter on a regular basis. Exactly how often depends on the air purifier. Some expensive models can go months to a year without a filter change, while the more affordable ones may need switching out every couple of months.
- Noise Level
Just like with common fans, not all of us want to hear constant loud noises from our air purifiers. It can quickly become an annoyance, but unfortunately, not every product details the noise level. You may find some that highlight how quiet they operate, so consider checking those out first, especially if you plan on being in the home while the purifier is running.
- Warranty
This may not feel like an essential until you need it, but a good warranty can go a long way to ensuring your product remains functional over time. Mold can always come back, so you want a system that’s reliable, but in the event it’s not, it should have a good warranty attached.
Air Purifier for Mold and Mildew – FAQ
Some people might go toward dehumidifiers when it comes to killing mold in the home. Dehumidifiers do work at removing moisture, which can be the issue behind the mold in your home. So, it’s helpful when you want to stop and prevent any more mold from coming in.
However, they don’t handle the mold spores that are already in the air. That’s why a good air purifier is useful in this case as it cleans the air from those harmful particles.
As long as you have the right type of air purifier, then it should do away with any color mold. Always check on the filter that’s used so you know it can remove the airborne mold spores as those particles are remarkably tiny and can pass through other filters with ease.
No, air purifiers on their own do not permanently get rid of mold or mildew. There is a combination of things you need to do to completely eliminate those issues. For one thing, if you see mold on the walls, floors, or furniture, then you need to clean it.
Whatever you can’t successfully clean, then you should throw it out. If the issue is too bad (e.g. in the drywall or ceiling tiles), then you may need to contact a professional.
Making the Decision
If we have to choose the best air purifier for mold and mildew from our list, we feel the Hathaspace Smart 5-in-1 True HEPA Air Purifier is the go-to choice. It has a remarkable five system setup that handles large and small particles as well as odor issues, comes with a 2-year warranty, and is easy to maintain over time.
You can also try out the more affordable LEVOIT Air Purifier for more compact filtration needs as it’s generally quiet and can handle simple mold issues well. Feel free to check them out or any of our products to learn more.
