Did you know that breathing in even small amounts of airborne mold could lead to severe short and long-term health problems? Although an air purifier cannot remedy the root of the problem, it is the first step to ensuring the air that you breathe is clean. This is why investing in the best air purifiers for mold is crucial.
On top of that, air purifiers do a lot more than just eliminate airborne mold. They have a whole plethora of additional benefits that ensure that the air that you breathe in your home is 100% clean.
So let’s not waste any more time and let’s dive into the reviews of purifiers for mold that our team has compiled.
Who Needs an Air Purifier?
Although having an air purifier is always beneficial, there are some situations where we believe it is absolutely necessary. Here are several reasons why you might need an air purifier in your home.
Mold and Mildew
As mentioned before, the right air purifier will help eliminate airborne mold in the home. However, you must also take measures to reduce the source, or the problem will continue to grow.
Smoker in the Household
To eliminate cigarette smoke fumes and smell, an air purifier with an activated charcoal filter will be necessary. Change the way your home smells and prevent second-hand smoke. You may also be interested in our guide on top-notch air purifiers for smoke.
Asthma, Allergies, or other Respiratory Problems.
One of the most common reasons people purchase an air purifier is because it was recommended they invest in one due to someone in the family having respiratory problems. Whether it’s allergies, asthma, or another issue, the right air purifier can considerably improve their everyday life.
Not only do pets shed a lot of furs, but they are also an allergen, can bring in allergens, and regardless of how much you wash them, they get stinky. An air purifier that also has an activated carbon filter and pre-filter will take care of the problem with the smell, dander, and even the fur floating in the air. While a HEPA filter will take care of the smaller particles such as dander and pollen.
You may also want to consider reading our guide on air purifiers for pets to get more details on how to handle air pollution and odor from pets.
Odors from Neighbors
If you live in an apartment, there is no need to even go into further detail. Cigarette smoke from the neighbor in the window upstairs, the spicy food the neighbor downstairs is cooking, the 3 dogs that stink up the entire floor. It all comes into your apartment.
Keeping your windows closed in the Spring to keep pollen out simply doesn’t cut it. Anytime anyone goes outside, they bring pollen into your home, especially if you have pets. If you are suffering from seasonal allergies, an air purifier may be the solution.
Wood Stoves or Fireplaces
There is nothing more beautiful than that cozy fire in the fireplace, and nothing worse than the smoke that fills the home. Even the highest quality fireplaces cause at least minimal air pollution that could irritate the eyes, throat, and respiratory system.
Who doesn’t love home-cooked food, right? Unfortunately, there is also an unwanted smell that sticks to clothes, furniture, and carpets if left unattended. By turning on an air purifier with a carbon filter, you can completely eliminate this problem.
Crafts Materials That Emit Toxic Fumes
This may seem innocent enough, but most of the glues, paints, mineral spirits and enamels can be very toxic. If you are regularly working with such products, prevent the buildup of toxic chemicals in your body but firing up an air purifier nearby.
Unfortunately, sometimes, your home is located in an area prone to dust. Whether it’s near a busy street, a construction site, or none of the above, some locations just ha. Another reason is regularly keeping the windows open and pets. As air purifiers pick up even the smallest particles, you can save time on dusting.
New Apartment/House Smell
There is a very distinct smell in new construction. Yes, it’s clean and brand new, but with all the chemicals used to complete it, such as paint, varnish, glue, carpeting, and more, the fumes can be dangerous. The toxins from the fumes will disappear over time, by why suffer until then?
From dust to fumes, renovations can be a dirty business. Keep an air purifier running to keep the air as clean as possible.
Fire Risk Zone
If you live in a fire risk zone, then you know about the health problems it causes to anyone breathing in the smoke. Even if the fire isn’t affecting your immediate area, clouds of smoke get blown about miles away and get into homes. A HEPA filter will do the trick in maintaining a safe breathing environment.
How do Air Purifiers Attack Mold?
When mold builds up in the home, it releases spores into the air. They then float around and eventually reach our lungs. Air purifiers function by pulling air in and passing it through one or several filters and then releasing the clean air back into the living space. It doesn’t get simpler than that. Then you get into the variety of filters, and things get slightly more complicated.
The reason it is crucial to either have a HEPA filter, or any other type of filter that can filter particles smaller than 0.3 microbes is that mold spores are 1-30 microbes. This means you must have a fine enough filter if you want to catch them.
Of course, an air purifier isn’t enough if you have a mold problem in your home. One of the most effective ways to find out if you have issues with mold is to get a top-notch home air quality test kit. It will give you an idea of what type of air purifier is necessary and what other steps you need to take to protect your family.
Another feature you should look for if you are trying to attack mold in your home is a carbon filter. Surely you are aware of the damp and musty smell that mold emits. What the carbon filter does is neutralizes odors from it, along with pets, smoke, and other household smells, especially those coming from the kitchen.

Features of Air Purifiers Necessary to Tackle Mold
Some features are absolutely necessary if you want to get the best results, while other features may be a great addition, but are not essential.
The Efficiency of the Filter
The quality of the filter is the most crucial feature you need to look for. You must get an air purifier that has at least two stages of filtration, but three is much better. A model that works with a HEPA filter alongside an activated carbon filter is the top choice. This combination not only ensures the spores are eliminated but their smell as well.
Choose an air purifier that has more than a one-speed setting. This will give you more control based on the current air quality in the living space. Higher speeds are ideal for cold months that are damp when mold is more prone to accumulate. Lower settings are suitable in the summer or when it’s warm because you can ventilate your home by opening windows, so mold growth is reduced. There are even air purifiers that feature smart sensors that allow them to adjust the speed of the fan according to the current air quality in your home.
Each air purifier has a specific size room that it can properly circulate air in. The smaller air purifiers can circulate air in a small 100 square foot room, while the bigger ones can handle 1,000 square feet or more. Make sure the one you purchase is suitable for the room size you will be using it in and not right on the higher end.
True HEPA Filter
As mentioned above, the filter is the most critical feature of the unit. Although there are HEPA-style or grade filters, your best bet is with a True HEPA filter. The True HEPA filter benefits simply make it better than any other option out there, so if your budget allows it, invest in it. If your budget does not allow for a True HEPA, the alternatives are better than no HEPA at all.
Automatic Mode Option
This is a fantastic feature that we highly recommend you look for. It means the air purifier has a sensor that gives you a live reading of the air quality. If the air quality is low, the fan speed is adjusted automatically to remedy that. This saves you time on guesswork and manually adjusting the fan speed yourself.

Noise and Light Pollution
With the topic in mind, pollution is the ideal word here. Many people are sensitive to the noise that most air purifiers make. Different units have different noise levels. Also, most purifiers have a lot of lights, and some are rather bright. If you are sensitive to either, make sure you research these points on each product you are considering so you don’t get disappointed.
Maintenance of Air Purifiers to Keep Mold at Bay
If you want your air purifier working at its best to eliminate mold spores in the air, you need to maintain it regularly. Not only will it improve performance, but it will enhance the life of the unit and filters as well. There are many advantages of timely air purifier maintenance, and the first most important is the proper function. The filter requires special attention and knowing how to clean your HEPA filter beforehand is essential. But there are a few more maintenance tips to consider.
Follow these cleaning tips:
- Never open or move the unit without unplugging it.
- Pay close attention to the pre-filter as it will require more regular maintenance. Due to the larger particles that it catches, it gets clogged faster. This is especially the case if you have pets. Some filters can be washed, and others vacuumed several times before requiring replacement. If the unit starts to emit a strange smell, then consider replacing the pre-filter.
- In case your particular filter is washable, never replace it back on the unit before it has thoroughly dried.
- If your unit has a HEPA filter, make sure you clean it every few months or more often, depending on the number of pollutants you have in your living area. They need to be replaced every 6 to 8 months. The filter comes with cleaning instructions.
- Never wash your HEPA or any other permanent filter as this could damage it.
- The air filters are delicate, so scratching or scrubbing it could damage it.
You will also find more in-depth information on the maintenance of the particular air purifier you have purchased in the manual from the manufacturer that comes with it.
