It is impossible to see mold around your home or office and let it blossom. Mold growing in your home can quickly degrade the quality of the air. The mold makes the air stuffy and the homeowner more prone to allergy episodes. It is therefore important that you protect your home or office from mold and mold spores. We understand that despite your best efforts to aerate your home, it is just too difficult to ensure some areas get complete circulation. This is how an air purifier becomes the solution to your problems. Intake of mold spores can cause lung irritation, as well as itching of eyes and nose, skin irritation and in some extreme cases can lead to hospitalization.

Mold grows well on paper like based products such as ceiling tiles, wood products, cupboards. It also grows in places with vapor such as around pipes, the roof, carpet, walls and fabrics. So mold is guaranteed to crop up in your home. So you will need an air purifier to remove mold growing in your home.

How will an air purifier help fight the mold in your home?

Certain air purifiers on the market are designed with special features meant to fight mold, mold spores and mildew. And some of the best rated air purifier for mold will include the following key features;

HEPA filter

One way to ensure that an air purifier has a fighting chance against mold spores is the HEPA filter. This filter is designed with such efficiency that it can capture small particles of up to 0.3 microns in size. You should know mold spores that settle in the air are within such a size category. Consequently, the HEPA filter will be able to remove the mold spores floating in the air. Most HEPA filters remove 99% of all allergens from your indoor air therefore making it much safer and cleaner. Therefore, this makes the HEPA filter a very good air filter for mold.

HEPA filters have different classes with their corresponding retention rates as shown below.

HEPA classesAverage Retention(>)
U17  99.999995%
U15 99.9995%
H13 99.95%
E12 99.5%

Mold air purifiers that incorporate silver ion HEPA filter technology help get rid of mold spores and bacteria more effectively hence giving extra protection.

Activated Carbon Filter

Air purifiers with carbon filters remove the bad smell that can result from mold growth.  Activated carbon filters are made with granular carbon mesh that is effective to trap all sorts of household odors including the repugnant smell that can be a by-product of mold growth.

These carbon filters can be found in multiple products not only limited to factory types but also some organic ones (for example those made out of coconut shavings).

The above-mentioned filters usually require regular replacement as directed by the purifier’s replacement guide. This is so as to ensure continued 100% effectiveness all year round.

UV -C- Light Filter

An extra filter of UV-C Light is highly encouraged to eliminate mold fungus 100%. The UV-C light destroys the nucleic acid found within the mold cells while the air flows through the filter. By using this filter, we are making kill mold completely. It is important to note that most UV-c light will take one to two hours to kill mold.

Area coverage

When purchasing an air purifier, you might like to take into consideration how big your home is. This is essential towards reducing down your gross cost if you might require more than one purifier to ensure full room coverage. Purifiers have different square meter coverage capacities and if one with small room coverage is used in a much larger space, you might not get the best results.

For the best results and long lifespan, we would advise you to choose an air purifier that operates at least twice the coverage area you intend to cover so that you can maintain minimal speeds and low noise.

Other factors include;


The device you purchase must be fully certified so as to ensure that it meets strict performance standards set up by the EPA (Environmental Protection Agency). You should also look out for these certifications that are worth considering like Energy Star, and the Association of Home Appliance Manufacturers (AHAM). These advise on the most suitable room size for the mold air purifier and provide the Clean Air Delivery Rate of each air purifier.


It’s important to check the warranty on the air purifier before you buy it. Mold is recurring, therefore you would need to invest in a mold air purifier that will last a long time or have an option to have it replaced at little or no cost in case it doesn’t work as expected. We therefore advise running the mold air purifier full time to keep your air well filtered and free from any mold and bacteria.

Our list ensures you easily identify the best air purifier for mold spores and what makes it so. So here is our list of air purifiers for mold.

In conclusion, fighting mold with these air purifiers is guaranteed to give you good results.

However, for better results, it is recommended to use an air purifier along with other good house practices for faster results.

  • Check and ensure proper air ventilation: Bathroom, toilets and kitchen are the areas most vulnerable to mold growth. Make sure that the ventilation work is professional enough and can also let all the moisture out of the house.
  • Fix any leakages:  A poor plumbing system or leaky roof can create the right environment for mold growth. If any wet areas occur as a result of these leakages, immediately dry them out and stop the leakages.
  • Drain rooms in case of flooding: Don’t ignore your flooded basement, this water will produce a lot of moisture and is the perfect environment for mold growth. So please keep watch of your basement area or any places in your house that are likely to experience this kind of disaster
  • Open Windows Often: While it seems like a lot of work to open windows every day, this is the cheapest and most effective way to improve air circulation in your home. Cool fresh air will be allowed entry and will drive out the dry and stuffy air.  So, if mold is your common house guest, then you might want to give yourself a push and get those windows open mostly when doing chores like cooking.
  • Clean Carpets often: If you smell an unpleasant odor in your rooms with carpets, it’s best not to ignore it, remove a part of it and do a thorough check because mold might be spreading in your house. Carpets are naughty for their high absorption of water that can lead to mold growth.  Invest in good quality carpets, vacuum carpets often and call a professional to attend to them and thoroughly clean them at least once every year to stay free from mold.
  • Don’t dry clothes inside the house: It can be less hectic to put clothes on hangers in the bathroom to dry but the moisture that evaporates from them can stick to the walls or ceiling and lead to mold growth. If you are lacking outdoor space to hang wet clothes consider investing in a dryer or even open all your windows when drying your clothes indoors.
  •  Invest in mold removal products:  Besides buying an air purifier, supplement this with a product at your local hardware store or supermarket as recommended by the specialists.

Finally, if all the above-recommended methods do not stop the mold, please consult a professional on the matter or consider relocating to places with less humidity and fresher air.

You can choose to prevent mold before it occurs but if it occurs, no need to panic, just pick your favorite air purifier and deal with it. There is no place like home, we therefore owe it to ourselves to keep a mold-free environment all the way.
