Are you looking for an air filter that can provide excellent protection while still allowing good airflow? If so, the MERV 11 20x20x1 air filter is the perfect choice for you. This type of filter is ideal for homes with multiple pets, people with respiratory problems and allergic sensitivities, commercial office buildings, retail stores and public spaces. The MERV 11 air filter is constructed of heavy-duty beverage cardboard to ensure that it maintains its integrity throughout its lifespan. It is designed to filter out airborne particles that can cause watery eyes, itchy throat, coughing and sneezing.
It is recommended to change filters at least every 90 days, but may need to be changed more often based on a variety of factors. The Glasfloss Z-Line MR-11 20x20x1 MERV 11 oven filters are an economical upgrade to the standard pleated air filters and excel where similar HVAC filters (heating, ventilation 26% air conditioning) are not enough. A high-strength recycled expanded metal reinforcement is laminated to the air outlet side of the filter using a thermosetting adhesive to ensure the consistency of the radial folds. These air filters have an efficiency of 85% in capturing particles in the range of 3 to 10 microns (see examples in the table below) and up to 80% efficiency in capturing particles in the range of 1.0-3.0 microns (see chart below).
While the MERV 11 provides excellent protection, it allows good airflow to keep your heating and cooling system running efficiently, saving energy costs and helping to reduce costly repairs. If you're looking for an air filter that can provide excellent protection while still allowing good airflow, the Glasfloss Z-Line MR-11 20x20x1 MERV 11 oven filters are an economical upgrade that will excel where similar HVAC filters (heating, ventilation 26% air conditioning) are not enough. Pets, poor air quality, respiratory problems, and other factors can affect the speed at which filters should be changed.
