Air Filter FAQs

The best air filter depends on size or dimensions, filtration rating (MERV, MPR, FPR), and quality. Our aftermarket filters are more affordable and higher performing than most OEM (original equipment manufacturer) brands

Replacing your air filter is as simple as finding the appropriate size, opening your intake vent, and placing your new air filter snugly in its slot. Be sure that your air filter isn’t bending or creasing to get maximum performance. Learn more about replacing your old air filter here.

Pleated air filters are so much better than fiberglass, that they are the only type we produce and sell. Our pleated air filters last 3-6 months (depending on the size and the filtration needs of your home) and capture over 85% of air particles in your space. Fiberglass filters, made of spun glass, last an average of 30 days and capture a much smaller percentage of air particles. You may pay more up front for the pleated filter, but it will pay you back in better air quality and less waste.

It is recommended that you replace your air filter every 90 days or 3 months.

Air filters are made primarily of cardboard, supporting wire, and the filter media. Depending on your filter needs, the filter media can be made of many different types of material, including fiberglass, polyester, cotton, and more.

Most central air units have two filters to allow air intake evenly throughout the house. This increases the ability for your HVAC system to circulate air at equal rates throughout your home and increases the amount of filtration.

Air filters can be found online and at your local hardware store. For the best results, buy your replacement air filters from a trusted air filter manufacturer like Filterbuy.

MERV stands for minimum efficiency reporting value, and it is a rating on how much filtration your air filter is capable of. Most air filters have a MERV rating between 1 and 20, with MERV 1 filters only capable of removing larger debris and MERV 20 capable of filtering out microscopic particles such a viruses and bacteria from the air. Filterbuy offers air filters in MERV 8, MERV 11, and MERV 13 ratings.

Air filters, furnace filters and AC filters are similar products and the terms are used interchangeably. Aside from size differences, the air filter that goes in the central HVAC unit or your return vents is called an “AC filter” or just “air filter,” and filters that go your furnace unit in your home are called “furnace filters.”

For new customers or new homeowners, you may need some assistance in ordering replacement filters online. Considerations including air filter dimensions or sizes, minimum efficiency reporting value, and the difference between air/furnace/HVAC/air conditioner filters all play role in finding the right air filter for your residential, commercial, or industrial application.

Read below for a quick guide to buying the right air filter.

Air filters have different sizes, brands, components, features, MERV ratings, and filter media. To make sure you’re getting the right air filter for your central air system, make sure you know some of the basics:

Replacement air filters can be properly sized by measuring their width, height, and thickness. Most people use the standard size printed on their existing air filter, but you can also measure for your specific air filter’s nominal size and dimensions.

MERV ratings indicate how much filtering power your air filter has based on the size of particles that it traps (air particles are sized in microns). MERV ratings range between 1 – 20, but most residential air filters are rated between MERV 8 and MERV 13.

Air filter media refers to the type of material used to filter particles out of the air. Most air filters feature fiberglass filters, cotton, polyester, electrostatic, and pleated media filter options that depend on what components you want filtered out of the air, like dust, pollen, allergens, viral particles, odors, and more.
