Review FILTER 21x13x1 Inch Mervmax Permanent Washable Electrostatic Air

Introducing the Filter DE13211E, a high-performance air filter designed to deliver superior air quality in your home. Measuring 21 inches in length, 13 inches in width, and 1 inch in depth, this filter is ideal for use in furnaces and air handlers that utilize the MERV (Minimum Efficiency Reporting Value) rating system and require a filter with a size of 20 x 20 x 1 or its equivalent.

This filter is classified as a MERV Max, which means it offers the highest level of filtration efficiency allowed by the MERV rating system. It is engineered with a permanent electrostatic media that captures and holds airborne particles as small as 0.3 microns, including pollen, dust mites, mold spores, and smoke.

The electrostatic media works by generating an electrical charge that attracts and holds particles to the filter surface, ensuring they are not released back into the air. The filter's high filtration efficiency makes it an excellent choice for individuals with allergies or respiratory issues, as well as for those who want to improve the overall air quality in their home.

One of the key benefits of the Filter DE13211E is its permanent design. Unlike disposable filters that need to be replaced regularly, this filter can be washed and reused multiple times, saving you both time and money. Simply vacuum or hose off the filter to remove accumulated dust and debris, and let it dry completely before reinstalling it.

Another advantage of this filter is its ability to reduce energy consumption and save you money on heating and cooling costs. By trapping more particles in the air, the filter helps prevent the buildup of dirt and debris on heating and cooling components, allowing them to operate more efficiently and effectively.

The Filter DE13211E is also easy to install, with a pleated design that fits snugly into standard filter frames. Its durable construction ensures long-lasting performance, making it a wise investment for homeowners who want to maintain a clean and healthy indoor environment.

In summary, the Filter DE13211E is a top-of-the-line air filter that delivers unmatched filtration efficiency, permanent design, and energy savings. Its ability to capture and hold even the smallest airborne particles makes it an essential component for anyone looking to improve their indoor air quality and breathe easier.
