Filterbuy 20x20x1 Air Filter MERV 11 Allergen Defense (1-Pack)

At Filterbuy, we are committed to providing customers with the perfect air filters for their homes and businesses. Regardless of the size or specifications required, we offer a vast selection of custom air filter options to ensure a perfect fit for any HVAC system.

Our air filters are distinguished by their premium features, including a pleated, electrostatically charged design that captures more particles than standard fiberglass models. Additionally, our reinforced beverage board frames are built to withstand extreme temperatures, outperforming standard cardboard frames.

We understand the importance of maintaining clean indoor air for a healthy lifestyle. Breathing in pollutants and allergens can lead to the development of asthma, allergies, and other respiratory issues. That's why we work tirelessly to give everyone access to the crisp, pure air they deserve.

Our air filters are available in a range of MERV ratings to suit different needs. The MERV (Minimum Efficiency Reporting Value) scale rates a filter's ability to capture particles, with higher numbers indicating more effective filtration.

MERV 8 filters are perfect for standard home or business use, trapping 90% of airborne particles as small as 3 microns. MERV 11 filters provide superior protection, capturing 95% of particles down to 1 micron in size, making them ideal for homes with pets, smokers, or allergy sufferers.

For the ultimate in air purification, MERV 13 filters offer optimal protection, removing 98% of particles as small as 0.3 microns. These filters are perfect for larger homes, businesses, or environments that require the best possible filtration.

In addition to our standard filter options, we also offer MERV 8 filters with activated carbon, which are designed to inhibit unpleasant odors.

Selecting the right air filter size is crucial for ensuring proper fit and optimal performance. We provide clear guidance on how to measure your existing filter and find the corresponding nominal and actual dimensions, making the replacement process seamless.

At Filterbuy, we take pride in our Made in the USA manufacturing process, with production facilities across the country. This allows us to quickly fulfill diverse, custom orders and deliver high-quality air filters directly to households and businesses nationwide.
