Things to Consider

It’s easy to feel overwhelmed when you’re on the lookout for the best air purifier for mold. You want the device to work well, but there are other factors to contend with, such as budget and dimensions. We hope this buying guide will enlighten you and make your next air purifier for mold spores purchase a bit easier.

How can an air purifier help to fight with mold spores?

Air purifiers are machines that take in the air in a room, put it through a filter, and release more improved air. While each machine is different, the filters will remove particles such as dirt, pollen, pet hair, and yes, mold spores.

When looking for an air purifier to fight mold spores in a room, it’s important to match the machine with your needs. Mold spores can be quite dangerous, especially for those with allergies, babies, or the elderly.

If you have a large room, don’t get an air purifier that is meant for a small space. You might think that the mold is being removed, when in reality, nothing much is happening.

Some air purifiers for mold spores will have electronic air quality monitors to show how efficient the product is. If the machine you buy doesn’t, it’s a good idea to purchase a separate one to gauge how effective your new device is.

And, even if your machine does have its own monitor, you might want to buy your own separate one. This is because the air at the edge of the room might not be as mold-free as the air circulating closer to the purifier.

Features to consider while choosing an air purifier

Air purifiers for mold spores have many features that make them stand out against the rest. We’ve compiled this list of features to help you understand what to look for in your next air purifier.

Type of filters

There are several major types of filters to be aware of for air purifiers. HEPA filters are the most common and are made of foam, cotton, or fiberglass. Ionizers and ozone filters produce a charge in the air. These charged particles then stick to normal air particles.

As a result, they stick to surfaces instead of remaining in the air. Electrostatic filters take this a one-step process. Instead of having air particles stick to surfaces, the air purifier actually collects and traps them. These filters need to be washed regularly.

Yet another type of filters is an activated carbon filter. These filters are great at trapping odors and gasses in the air. You can use activated carbon filters with other filters, and together they make an impressive combination.

One final type of filter is the UV filter. The UV light produced can actually kill microbes, including some germs. If you have a compromised immune system, having a UV filter can protect you from becoming sick all too often.

Fan speeds

An air purifier requires a fan to push out the clean air into your room. The larger the room, the more powerful fan speed you will need to reach all those corners. Some air purifiers are more basic than others, like the TRUSTECH 3-in-1 Compact Air Purifier which only has two speeds.

Other air purifiers are quite sophisticated, such as the futuristic Dyson Hot+Cool HP04 which has a whopping ten speeds.

The larger the range of fan speeds, the more control you have over noise, too. Even the quietest air purifier will make some noise with its fan. If you want to keep the device on at night, but don’t like much noise, then having a very low fan speed will be a big asset.

CADR level

In the world of acronyms, some are more important than others. CADR stands for Clean Air Delivery Rate. This number indicates how much filtered air travels through the machine.

The number is devised by the Association of Home Appliance Manufacturers and is independent from the device’s original manufacturer.

It’s important to note that a CADR level is only for portable air purifiers and not for stationary whole-house air purifiers.

The CADR level is broken into three categories. Tobacco smoke is measured from 10 to 450, dust is measured from 10 to 400, and pollen is measured from 25 to 450. The higher the CADR rating, the more efficient your air purifier is.

Coverage area

The coverage area of an air purifier refers to how large of a space the device will work in. The products on our list all have quite the range of coverage areas. The TRUSTECH 3-in-1 Compact Air Purifier has the smallest coverage area, at just 50 square feet.

This means it is suitable for a small bedroom, small trailer, or an office. If it is placed in a larger area, it will not be effective.

The largest coverage area for a product is the Green Air Encore Air Purifier at 1,000 square feet. This machine is perfect for an open concept room, an apartment, or even a basement. It is a heavy-duty machine and will work well to rid your air of any toxins.


Some air purifiers are small. Some are large. The rule of thumb is that the more powerful a product is, the larger it is, and with a few exceptions, this is true of air purifiers for mold spores. Before you purchase any product, be sure to think about where you want to place it.

If you don’t have a good area to hide your air purifier in your living room, will you be ok with it out in the open? Likewise, if you want to place your air purifier in a small area, such as a shelf. Be sure to measure well, so you know which will fit.

One last thing to keep in mind with dimensions is the cord. Air purifiers run on electricity so unless you want a cord running through your room, think about placing your device near an outlet.


Air purifiers for mold spores come in all shapes and sizes, as do their warranties. But, as with all electrical devices, having a warranty can provide you with much needed peace of mind. A standard coverage for an air purifier will be one year in length. You might get lucky and find a product with a two or three-year warranty.

In addition to the length of a warranty, it’s a good idea to pay attention to the customer service. If there are negative reviews about customer service, then if you need to return your product, even if you have a warranty, it might be a hassle.

No matter how long your warranty is good for, be sure to mark it down in your calendar. At least one month before it is up, do a thorough examination of your purifier. There’s nothing worse than realizing something is broken mere days after a warranty expires.

Extra features

When it comes to the best air purifiers for mold, the sky is the limit for extra features. More basic, budget-friendly devices will have minimal settings and few indicators.

Air purifiers on the other end of the spectrum may have such extra features as color changing night lights or a remote control. With the advent of smart home technology, innovative air purifiers will use Wi-Fi so you can control your device from your smartphone.

While it might not be a huge priority for some, the design element of an air purifier is something to consider. If your machine will be visible in a room, it’s a nice bonus if it blends into your décor. It’s always unfortunate to have a large black machine taking up precious space in your living room.

How to maintain an air purifier

Your air purifier will only work if you maintain it properly. Like anything mechanical, regular tune-ups and cleaning are important to ensure a machine that works well all the time. The biggest issue with maintaining an air purifier is that there will likely be multiple parts to attend to.

First, read your instruction book thoroughly. If you’re still confused, look online for video tutorials that walk you through step by step. Remember that all air purifiers are different, so the maintenance plan for one will not be the same for another.

Start by understanding what types of filters are used in your air purifier. Some filters need to be taken out and cleaned. If this is the case, soapy water and a soft cloth should do the trick. Other filters need to be completely replaced. In this case, be sure to have a supply of filters on hand so you can easily swap them out when needed.

Thankfully, most air purifiers will have indicator lights when a filter needs to be cleaned or replaced. But, if you have an air purifier in a basement or another out of the way place, be sure to remember to actually look at your device and check for indicators.


How often will I need to replace the charcoal and HEPA filters?

A HEPA filter in an air purifier should be replaced every three to five years. If you are particularly worried about your air quality, then err on the side of caution and replace it sooner or later. Check your instruction manual and machine to see what indicator lights there are to alert you when your HEPA filter needs to be replaced.

As for charcoal filters, these need to be replaced every six months to two years. Again, check to see what indicator lights or levels are on your air purifier to help you with this task.

Are such devices loud to keep them running at night?

Air purifiers use a fan to circulate air through the machine, and fans are loud. If you are worried about how loud your device will be at night, look for an air purifier that has multiple fan settings. This way, you can choose the lowest setting for when you sleep, which will also be the quietest.

If there are only two fan settings, chances are the lowest one will still be rather loud. If there are six settings, the lowest one should be perfect for your sleeping needs.

For how long is it advisable to leave the appliance running to remove all the mold?

Air purifiers for mold are meant to be run all day long. You may think that you can turn off a device while you at work, just as you would do with the lights or the heat. But when you get home, your air will not be as clean as you like. Therefore, run your air purifier continually so that what you breathe is always as clean as possible.

Because an air purifier should be on at all times, it’s nice when there are multiple settings. For example, if you can program the air purifier to run at a lower fan setting while at work, you can still get the benefits of clean air, but it will be more energy-efficient. Likewise, if you want a quieter machine at night. The more options you have, the better your air purifier will fit into your life.
