What to Look for in the Best Air Purifier for Mold

When shopping for a new air purifier for mold, there five big things to keep in mind. Let’s take a look:

  • Size
  • Targeted pollutant
  • Noise level
  • Filtration system
  • Appliance features

See our article: How Does an Air Purifier Work?

Size

It’s essential to choose an air purifier suitable for the size of the room. Air purifiers come in a variety of sizes, cleaning capacities, and efficiency ratings.

An air purifier’s cleaning capacity is based on a metric called the clean air delivery rate (CADR). CADR is simply the measurement of the purifier’s efficiency (the amount of clean air the device can deliver in an area of a particular size).

Another useful metric is cubic feet per minute (“CFM”), which tells you how much clean air the purifier can circulate every 60 seconds.

Of course, the higher the CADR and higher the CFM, the bigger the room the purifier can handle.

This handy table below shows minimum CADRs for various room sizes.

Purifiers are often listed with two CADRs, one for particles (often labelled simply as “pollen”), and one for smoke.

Be sure to consider the CADR for the pollutant you’re looking to eliminate (more on that below)

Targeted Pollutant

If you have a specific air pollutant that’s motivating your purchase, of course that’s a top consideration.

Most air purifiers come with two types of filters: a particle filter designed to remove microscopic pollutants from the air, and an activated carbon filter which helps deal with gasses and odors.

You’re here because you want an air purifier for mold. Mold is comprised of fungus that tends to release an unpleasant odor. For that reason, we recommend you get an air purifier that has both a good particle filter and an activated charcoal filter. The particle filter will work to remove microscopic mold spores from the air before you breathe it in.

The activated charcoal filter will work to remove the odor mold can cause from the air.

Noise Level

If the mold in your house causes some allergies and respiratory issues, you may want to keep your air purifier running throughout the day (and probably overnight as well). This means operating noise level is important.

The noise from a typical air purifier is usually minimal, ambient noise. However, the noise level varies depending by model and operating speed.

The noise level of a purifier is measured by decibels dB, and each model will have its decibels on the product specifications. We recommend an air purifier’s noise volume be around 32 dB.

Filtration System

Filtration is the backbone of any air purification device, so the best purifiers meet a certain filtration standard.

The highest quality purifier filters earn the designation known as HEPA filter (often referred to as “True HEPA”).

Warning! Some manufacturers label their filtration system as “HEPA-like.” If you’re looking for the most effective air filtration, be sure to stick with air purifiers that have “HEPA” or “True HEPA” in the description.

Appliance Features

Air purifiers come with a variety of add-on features. Of course, you are the best judge of what features matter most to you.

Below is a list of more common features so you’ll know what to look for when shopping.

  • Digital controls for easy access to settings
  • Filter replacement indicators to help you know when the filter needs cleaning
  • Pre-filter to capture the largest particles and protect the internal filters
  • Adjustable fan speeds to speed up or slow down the air cleaning process.
  • Programmable timer to save energy and keep the device from running when you don’t want it to
  • Air quality sensors to monitor the air for particular pollutants and automatically adjust the purifier to the appropriate level needed to eliminate these impurities
  • Nightlight in case you’ll use your filter in a bedroom
  • Carrying handle for easy moving of your device between rooms without hassle
  • Remote control for easy operation
