A clogged or dirty air filter restricts airflow, which causes your heating and cooling system to work harder and use more energy to warm or cold your home or/and office. Just like you replace your car’s air filter, consider replacing your HVAC air filter to protect your system from expensive repairs. In addition to driving up your energy bill, your indoor air quality also gets polluted and exposure to this polluted air causes many severe respiratory health problems. So what’s the big deal? Does your HVAC air filter really matter?

Merv Filters LLC recommends checking your HVAC air filter every month and if you find it dirty, black; change it, especially in the peak months of summer or winter when your system is constantly in use. Our team of filtration experts ensures that the standard size filters are always in stock. Order online and get it delivered to your door within 3-5 days. If you don’t find the standard size filter that meets your needs, order custom size filter online.

Our 18x20x2 MERV 11 filter is designed for superior filtration efficiency, capturing allergens between 1 – 10 microns, ensuring you breathe clean air. The electrostatically charged, filter media is bonded to corrosion resistant expanded metal support grid. The filter media is unaffected by the moisture and can withstand harsh conditions.

Important Note: When looking to replace your air filter, make sure you compare its nominal size and actual size. The nominal size that is printed on the side of your air filter is rounded up to the nearest whole inch. For example, if the nominal size of the filter is 18x20x2, the actual size will be 17.5×19.5×1.75
