Review on 2-Pack MERV 11 Allergen Defense Air Filters - 10X14X1 Inch Size, HVAC AC Furnace Replacement With Pleated Design (Actual Size: 9.50 X 13.50 X 0.75 Inches) By Filterbuy by Anthony Savage

The 2-Pack MERV 11 Allergen Defense Air Filters are designed to provide maximum protection against airborne allergens, including pollen, dust mites, and pet dander. These filters are made from high-quality materials and feature a pleated design that maximizes airflow while trapping harmful particles. One of the things that stood out about these filters is their size. At 10x14x1 inches, they were a perfect fit for my HVAC AC furnace system. However, the actual size of the filters is 9.50 x 13.50 x 0.75 inches, which is something to keep in mind when ordering. The MERV 11 rating of these filters indicates that they are capable of capturing a wide range of particles, including those as small as 1 micron. This is great for individuals with allergies or respiratory issues, as it helps to improve indoor air quality. That being said, I did notice that these filters become clogged quite quickly. After just a few weeks of use, they were noticeably dirty and needed to be replaced. This may be due to the high filtration rating, but it could also be a downside to consider. Overall, the 2-Pack MERV 11 Allergen Defense Air Filters are a good option for those looking for a high-quality air filter that will provide protection against airborne allergens. However, they may require more frequent replacement than other filters due to their high efficiency.
