Mold is a common household problem that can cause respiratory problems, allergies, and more. That’s why it's important to know the best ways to get rid of it so you can breathe easier in your own home. The first thing you should do is purchase an air purifier for mold filtration if you don't already have one! 

Mold thrives on moisture and grows faster when the humidity levels are high. If it's not taken care of quickly enough, then it will spread throughout your entire house. You need to find out where there might be leaks or moist areas in your home - these are prime spots for mold growth!

This blog post discusses different options where you can strategically place your air purifier for mold filtering. If you're not sure where to put it for best results, we've got some great ideas!

Do Air Purifiers Eliminate Mold Spores?

Yes, air purifiers can get rid of mold spores from your home's air by trapping them on filters before they enter your lungs. Ensure to look for an air purifier with a HEPA filter or meets HEPA standards which will trap and remove at least 99% of particles from the air passing through it.

Best Places to Put an Air Purifier for Mold Filtration

1. Bedroom

If you're someone who suffers from allergies, asthma, or other breathing problems, then it's especially important to have an air purifier in your bedroom. Mold can worsen these conditions and make it difficult to sleep at night.

Bedrooms need special attention because people spend about 70% of their lives there sleeping throughout the night! This is why many homeowners report finding mold on bedding materials like sheets and pillows.

You might also want to put one in the corner of your bedroom, especially if you use humidifiers for dry skin issues, as the moist air can cause mold problems quickly.

2. Kitchen

The kitchen is a high-traffic area in the home and one of the most common places for mold growth due to moisture from cooking. A kitchen air purifier can help reduce the amount of spores in the air and keep your family safe. Additionally, this machine can help remove cooking odors from the air.

Placing it near the refrigerator is a good place to start. Other good locations include near or underneath cabinets, the dishwasher area, and in close proximity to any bathrooms in the home.

3. Living Room

One of the most common places to put an air purifier for mold is in the living room. This is because a lot of people spend time in this area of the house, and it’s also where many allergies tend to flare up. 

By having an air purifier in this space, you can help reduce your exposure to allergens and keep your asthma under control. If you have pets, be sure to place the air purifier near their sleeping area, as pet dander is a known allergen.

4. Rooms Under Construction

An air purifier should be placed in any room that has been recently remodeled or painted, as these activities can release a high amount of mold spores into the air. This will also help remove the dust and dirt particles.

5. Near Doors

If you have a garage, put an air purifier near the door leading into your house and in any other moist or dusty areas. This will help to keep any mold spores from entering your home. And if you have a basement, put an air purifier near the entrance and in any other damp areas.

6. Near the Furnace

Air purifiers are excellent for helping clean up dust and allergens, but they can sometimes aggravate allergies if placed right next to vents bringing these particles into the house. If you feel like it's too much of a problem, you should place an air purifier near the furnace instead because it is usually hidden away from view anyway.

7. Storage Area

Another good place is near any areas where you store your firewood or camping gear. This will help filter out all the moisture in there and keep it from getting moldy.

Where Not to Put Your Air Purifier

Window Sill

The sun shining in through the window is great for brightening up a room, but it can also work against you when trying to use an air purifier to get rid of mold spores. Direct sunlight will heat up the machine and cause it to run less efficiently, so try placing it on a different surface or in a shaded spot instead.


While bathrooms can be breeding grounds for all sorts of nasty things like mold and mildew, that doesn't mean your air purifier needs to live there too! If you're using one specifically for filtering out these types of pollutants, put it somewhere else in the house where it's more likely to be effective.


Do not put an air purifier in your basement if you have a problem with mold or moisture there. It may make things worse by adding ozone to the already damp environment which is a good place for molds to grow.

What’s the Difference Between Air Purifiers, Air Cleaners and Air Filters?

Air cleaners and air purifiers can both be defined as devices that filter out pollution to make indoor air healthier for us humans. These contaminants can be anything from dust particles to chemicals to pollen and spores. The way they work is simple: the purification process traps these particles in air filters or forces them to attach themselves to surfaces.

Air filters are just one component needed by an air purifier or air cleaner to function properly - they usually also come with other components like HEPA filters.

What to Look for in an Air Purifier for Mold Spores?

Air purifiers are effective at removing mold spores from the air. However, it is important to note that not all air purifiers are created equal. Some air purifiers are better at eliminating mold spores than others. So, when shopping for an air purifier, be sure to choose one that is specifically designed to filter out mold spores.

  • High CADR Rating - The Clean Air Delivery Rate (CADR) is the amount of purified air that an air purifier can produce each minute. This is important because you want a machine that can clean the air quickly to prevent mold spores from spreading.
  • HEPA Filter Quality - Make sure the HEPA filters are high quality and will capture mold spores. The higher the MERV rating, the better the filter will be at trapping particles.
  • Filter Life Indicator - You'll also want to find an air purifier with a filter life indicator, so you'll know when it's time to replace the filter.
  • Low Noise Levels - Choose an air purifier that is quiet so you aren't distracted by noise when trying to sleep or focus on other tasks.

How Do HEPA Filters Work on Mold?

Mold spores are one-tenth the size of a dust particle or between 4 to 20 microns. The mold spores will usually have germinated by the time you notice them, so it is important to get rid of them ASAP before they reproduce and start causing other problems in your home.

HEPA filters work by forcing air through a fine mesh that traps particles down to 3 microns in size. The resulting pressurized airflow is said to be cleaner and healthier than many other filtering methods on the market today.

If you are concerned about mold in your home, it is a good idea to install a HEPA filter in an area where you spend the most time. Some of the best places to put an air purifier for mold filtering include the bedroom, living room, and kitchen.

Each of these rooms is likely to have areas that are more prone to mold growth than others. By placing a HEPA filter in each of these key spaces in your home, you can ensure that you are constantly breathing clean air.

How Often Do You Need to Change an Air Purifier's Filter?

Checking the filter of an air purifier

The lifespan of an air purifier's filter depends on the type of filter it uses and how often the air purifier is used. Generally, you should change an air purifier's filter every six months to a year. 

However, if you have pets or smoke in your home, you may need to change the filter more frequently. Consult your air purifier's manual for specific instructions on when and how to change the filter.

It is also important to note that some air filters can be washed and reused. If your filter is reusable, make sure to follow the manufacturer's instructions for cleaning and drying the filter before putting it back into the air purifier.


Mold is a problem that many people are faced with, especially in the fall. It can get into your home through open windows or doors, or by traveling on clothes and shoes. 

Air purifiers are an excellent way to remove mold spores from the air you breathe at home. There are many places in the house where an air purifier can be placed to help filter out mold spores. Some of the most common places are the bedroom, kitchen, and near or inside doorways.

It is important to remember that different types of air purifiers work better in certain locations, so be sure to visit Your Elegant Bar before making a purchase.
