  • Before we get into the different types of air purifiers on the market, let’s take a minute to discuss high-efficiency particulate arrestance, or HEPA for short.
  • In order to be classified as HEPA, an air filter must remove no less than 99.97 percent of particles 0.3 microns or larger from your air.
  • This standard, enforced by the Department of Energy, makes HEPA air filters the gold standard for allergen and airborne particle removal.

1. Type of air filtration technology

Choosing the right filtration technology is probably the most important part of buying an air purifier. Remember when you listed your specific air quality concerns? This is where they come into play. Different types of filters can tackle different types of indoor  air pollution. It is crucial to make sure that you are getting one that can handle your specific needs.

  • True HEPA filters are rated to capture at least 99.97% of particles 0.3 micrometers (µm). Units with HEPA filters may mention industry standards such as CADR or MERV values, but these numbers are not necessarily the best indicators of an air purifier’s performance.
  • Carbon filters trap gaseous pollutants, such as VOCs, in the air through a process called adsorption. As these filters become more saturated, they become less effective. activated carbon filters cannot remove particle pollution from the air.
  • PECO-Filter technology does not trap airborne pollutants. Instead, this patented molecular technology destroys pollutants like VOCs at the molecular level.
  • Ionizers work by releasing charged ions into the air. These ions then attach to airborne particles, giving them a charge that makes them either attach to surfaces in your home (such as walls and furniture) or fall to the ground. The technology used in some ionizers can create ozone as a byproduct, which may cause a long list of harmful health effects according to CARB [CALIFORNIA AIR RESOURCES BOARD].

2. Design and ease of use

A lot of things fall under this umbrella, such as aesthetics, portability, ease of set-up and Wi-Fi accessibility. Consider the room in which you will place your air purifier. You want to choose a model integrates into your daily life with minimal interruption. For you, that may mean matching your home decor. For others, it may mean having something that they can set up and forget about. Some questions to consider include:

  • What are the dimensions and weight of the air purifier unit?
  • What is the size of the room in which you will place your air purifier?
  • How complicated is the user interface?
  • How many settings options does the unit have?
  • Can the air purifier be controlled by a phone app or remote?
  • Will the air purifier notify you when it is time to replace the filters?

3. Noise level

If an air purifier is too loud, the chances of you using it regularly are slim to none. Whether you like to relax in total silence or enjoy having white noise playing in the background, checking an air purifier’s sound ratings can help give you a better idea of what to expect in terms of noise. (Keep in mind, an air purifier’s noise level will change with different fan settings.) The quietest air purifiers on the market will have a dB rating of 20-40 at the lowest fan speed, while the loudest ones will be rated 50 to 70 dB and above. To put this into perspective:

  • 30 dB is about the same noise level as a whispered conversation.
  • 50 dB is similar to a normal conversation or moderate rainfall.
  • 70 dB is as loud as running a vacuum or sitting in rush-hour traffic.

4. Energy consumption

  • If you are not careful, your air purifier’s energy consumption can lead to unpleasant surprises on your monthly electricity bill.
  • To keep energy costs low, try looking for units that use below 100 watts on their highest setting.
  • For example, our Molecule Air uses 20 to 80 watts of energy when in use, and the Molecule Air Mini only uses 18 to 53 watts. The Office of Energy Efficiency & Renewable Energy provides an online calculator that can help you determine how the addition of an air purifier can impact your yearly energy bill.

5. Cost of maintenance

  • During the life of your air purifier, you will need to replace the filter(s) regularly.
  • Filter life can range from a few months to a year, depending on the pollutant levels in your home and the type of filtration technology in the unit.
  • When considering the cost of an air purifier, make sure to factor in the average yearly cost of filter replacements (the cost of replacement filters multiplied by the number of times the filters need to be changed each year). Note that some air purifiers have more than one filter that will need to be replaced regularly.
  • Additionally, note the air purifier’s Warranty and return policy. What happens if the air purifier breaks or you realize that it is not right for your home? When you are investing in an air purifier, you want to know that you will be in good hands if anything breaks, or if you decide to return the product.
