Air purifiers are devices that help to improve the air quality inside your home by removing impurities and pollutants from the air. They work by using a fan to draw air into the unit, where it passes through one or more filters that capture pollutants and particles from the air. The newly cleaned air is then circulated back into the room. The filtration process repeats several times an hour, continually boosting indoor air quality.

Different air purifiers use different types of filters, but the most effective ones use HEPA (High-Efficiency Particulate Air) filters, which are designed to capture at least 99.97% of particles in the air that are 3 microns or less in size. These particles include allergens, dust, moisture, bacteria, viruses, and dirt. Some air purifiers also use activated carbon filters to capture molecules that cause odors, while others use ultraviolet (UV) germicidal irradiation to target airborne viruses, bacteria, and fungal spores.

While air purifiers may not directly or immediately improve a persons health, studies indicate that these devices can help to reduce your exposure to harmful pollutants, which may have long-term health benefits. However, an air purifier’s effectiveness varies depending on its filter type and the pollutants present in your space. Before investing in an air purifier, you may want to invest in an air quality home test to determine what contaminants you have in your home.
