What Type of Filter is Best for Air Purifiers? - An Expert's Guide

When it comes to air purification, the Department of Health recommends HEPA (High Efficiency Particle Absorption) filters as they are capable of eliminating at least 99.97% of allergens and pollutants from the air, including mold spores and dust as small as 0.3 microns. The CADR (Clean Air Delivery Rate) reflects the volume of clean air produced by an air purifier at its highest speed. To extend the life of the main filter and save money on replacement filters, reusable filters can be used to collect large particles before they reach the main filter. Particle counters can detect how polluted the air is and automatically adjust the cleaning speed of the air purifier accordingly. HEPA filters are more effective than ionic air filters and can remove up to 99.97 percent of airborne particulates, making them an excellent choice for sensitive applications.

We like other Blueair products, and this one adds cool air to its purification capabilities: it circulates air five times an hour in a 326-square-foot room.Air purifiers can help clean your home air of unwanted particles, such as pet dander, allergens, and smoke. These HEPA filters are made of several layers of filtering material and are required by law to filter at least 99.97% of particles larger than 3 microns in diameter. The 360-degree HEPA filter cleans rooms up to five times per hour when placed in an 80-square-foot room and twice an hour in a room up to 200 square feet. Few field studies have been conducted to explore the efficacy of PCO (Photocatalytic Oxidation) air purifiers, but a laboratory study conducted by researchers at Syracuse University in New York revealed that the devices did not effectively remove any of the VOCs (Volatile Organic Compounds) normally found in indoor air. When selecting an air purifier, it is important to consider why you want one, how well it filters the air, and what your budget is. This portable machine is designed for home use and has washable filter components to extend the life of the filter.

Medify Air is another popular brand, especially among those who need air purifiers for medical reasons. Some, such as those used in several Blueair models, do not cause a net increase in ozone in the air being filtered. If pollen or related allergies prevent you from opening windows, run the air conditioner or forced air cooling system with a clean air filter. In conclusion, HEPA filters are considered to be the best type of filter for air purifiers due to their ability to remove up to 99.97 percent of airborne particulates. They are also required by law to filter at least 99.97% of particles larger than 3 microns in diameter.

However, it is important to consider why you want an air purifier, how well it filters the air, and what your budget is before making a purchase.
