Merv Filters LLC carries a number of efficient air conditioner filters for your residential or commercial use. An effective furnace filter is vital to improving the quality of your indoor air. Without a reliable air conditioner filter, indoor pollution due to the chemicals that are used in the household can cause solid contaminants such as smoke, pollen, dust, grease, and pollen in your air. This can affect your health, causing asthma or other respiratory diseases.

Our 28x30x4 MERV 11 furnace filter is crafted using electrostatically charged, 100% synthetic graduated density filter media that captures filter particles, including dust mites, pollen, mold spores, pet dander, dust and smog. Our MERV 11 filters do not absorb moisture and resistant to a wide range of chemicals. We offer 28x30x4 MERV 11 air filter in a pack of 4 and 6 filters. Order online and get it delivered within 3-5 days.

In case you don’t find a suitable size filter for your HVAC, discuss your requirements with our friendly support team. We offer high-quality custom furnace and air conditioning filters, starting as low as $4.99.

Important Note: Whenever you search for air filters online, make sure you find the right size filter that meets your HVAC requirements. There are two filter sizes – nominal size & actual size. Most of the time, the actual size of a filter is often slightly smaller than the size written on the box (the nominal size). For example, if the nominal size of the filter is 28x30x4, the actual size will be 27.5×29.5×3.75
