Which Air Filter is Best for Allergies? A Comprehensive Guide

When it comes to allergies, the best air purifiers are those that contain a high-efficiency particulate absorption (HEPA) filter. This type of filter uses paper, fiberglass or mesh to capture contaminants and then releases clean air back into the room. HEPA filters are effective at removing smaller particles, such as tobacco smoke, and medium and large particles, such as dust and pollen. Carbon-based filters are also good at filtering out some particulates and odors, but they are not as effective at removing dust, dander, pollen and mold.

They filter what is in the air and not pollutants that settle on walls, floors and furniture. To keep your allergy symptoms at bay, you need an efficient air purifier that will help keep the air in your space clean and dandruff-free. Look for a unit with a washable carbon filter and pre-filter to save money on filter replacement. You can also search for the Clean Air Supply Rate (CADR) to determine how many particles and square footage an air purifier can reach. The Dyson Pure Hot + Cool is a powerful device capable of filtering air in spaces up to 999 square feet.

It has a four-stage filtration system, which includes a pre-filter, a deodorizing filter, a true HEPA filter and a vital ion filter. Some household air purifiers have an air quality indicator, which typically uses an infrared beam and a sensor to detect particles. While air purifiers help remove allergens, dust and other particles from the air, humidifiers provide moisture to the air and remove some of the largest particles in the environment. We researched the most in-demand air filtration systems in their respective categories and found that activated carbon, UV and HEPA air purifiers were among the most popular types of filtration on the market. With an activated carbon HEPA filter, room air is filtered through four levels of cleaning to collect microscopic particles that often trigger an allergic reaction, such as pollen, dust and pet dander. The Pure Cool Link air purifier also acts as a fan to keep your home cool during warm months.

It has multiple fan settings that operate on a timer and will not disturb the sleeping baby.
