AMERICAN-MADE MERV 11 AIR FILTERS
GUARANTEED TO FIT

If you’re looking for an air filter that captures 95% of airborne particles in a standard or superior home or business, the FilterBuy MERV 11 filter is the right one for you! This pleated filter traps particles as small as 1 micron, keeping pet dander, lint, dust, pollen, debris, mold spores, smoke, smog, and more out of your space. If you’re looking for a different MERV rating, you can check out our MERV 8, MERV 13, and Charcoal filters.

While the higher the MERV rating, the more particles it removes from the air, it doesn’t always mean it’s a better filter for you. Not only does a higher rating mean a greater percentage of trapped bacteria, it also means thicker pleats that will require increased air flow from your HVAC. This is why it’s important to choose your rating based on your needs, as well as what your system can handle.

We offer various MERV ratings not only because different homes and businesses need different efficiency, but also because not all furnaces are the same. That’s why there’s no single rating that’s “best.” We recommend considering your lifestyle (allergies, asthma, etc.) and the age of your HVAC equipment to determine the MERV rating that’s best for you. To make sure you’re getting the right MERV rating, check if your furnace manufacturer has a maximum rating your furnace model can use.

Our 1”, 2”, and 4” MERV 11 air filters are designed to last approximately 3 months, while our MERV 11 whole house replacement filters should be replaced every 6 months. If you have pets, kids, or allergy sufferers in your space, we recommend changing your filters more often. It’s important to replace your filters regularly, as the older an air filter is, the less bacteria and dirt it’s removing from the air, leading to poorer indoor air quality and higher energy costs.

We carry ratings ranging from MERV 8 to MERV 13, which cover the efficiency most homes need. These ratings provide clean, healthy air and protect your HVAC equpiment. Lower ratings (MERV 1-5), most often used for fiberglass filters, provide minimal filtration. Though higher ratings (MERV 14-20) capture very small particles, they tend to be much more expensive and place more pressure on heating and cooling systems to work harder.
