How does a busy shopper find the right size air purifier for a room they want to clean? The U.S. Centers for Disease Control recommends paying attention five air changes per hourin a metric known as ACH. When looking at an air purifier, pay attention to the airflow in cubic feet per minute at the lowest setting. If you’re measuring the cubic area of your room, you’ll need the Space times height. Imagine a 30cm Styrofoam cube. How many cubes fit in a room?
Anyone buying an air purifier also has to look for two acronyms and terms. First, look for CARB certification, which means the air purifier meets strict standards California Air Resources Board. Next, check the filter type. Below we explain the differences. Also, don’t forget to unpack your filter! It’s a real horror when you realize that you’ve been using your air purifier with a HEPA filter wrapped in plastic.
HEPA filter: That is a highly efficient particle air filter which can remove at least 99.97 percent of dust, mold, pollen, bacteria and airborne particles as small as 0.3 microns. It is a great option for those who suffer from allergies or respiratory problems, as it can help remove particles from the air that can trigger symptoms such as sneezing, sore throat, difficulty breathing, coughing and more. However, it is worth noting that HEPA filters do not remove volatile organic compounds from the air like activated carbon filters. However, these are typically combined with carbon filters.
Activated carbon: Activated carbon filters (also called activated carbon) are highly effective because they are very porous and have a large surface area, which allows the filters to absorb gas pollutants, odors and VOCs. That’s them best for removing fumesSmoke and chemicals from the air. But these filters must be replaced more often depending on the environment. For example, if a forest fire breaks out in your area and the air purifier is operating more intensively than usual, it is important to replace a saturated filter to prevent toxic gases from being released back into the air.
Washable air filters: Some of the air purifiers listed in this guide come with washable pre-filters in addition to a HEPA and/or carbon filter – which is what you’ll typically find. These are the most cost-effective because you don’t have to buy new filters every time you need to replace a filter. Simply remove it, scrub it with soap and water and let it dry.
UV-C disinfection filter: Ultraviolet filters use UV light to kill viruses, parasites, mold spores and bacteria. She Cannot be removed They contain airborne particles, VOCs or gas pollutants and are therefore only fully effective when combined with a HEPA filter. According to the United States Environmental Protection AgencyUV light without proper lamp coating can emit ozone. We recommend checking this list from the Association of Household Appliance Manufacturers for air purifiers that have been proven to emit little to no ozone.
