Read on to learn more!What Are Air Filters?Air filters are designed to provide fresh, clean air for your home while also filtering out harmful particles like allergens and bacteria.

They can be found behind intake grilles (often called air filters or AC filters) or in the oven box of the central air unit (often referred to as “oven filters”).

How to Find the Right Size Air Filter

When replacing an air filter, most people will find the nominal size or dimensions on the edge of the current air filter. This is the actual size rounded to the nearest centimeter. For example, if you have a 20x20x1 inch filter, it would be referred to as a 20x20 nominal size. Once you have the nominal size, you can use it to find the right size filter for your home. At Filterbuy, we offer a wide selection of standard air filter sizes, each with MERV ratings and odor-fighting options.

MERV Ratings

Most air filters have a MERV rating between 1 and 20.

A MERV 1 filter is only capable of removing larger debris while a MERV 20 is capable of filtering microscopic particles such as viruses and bacteria from the air. The higher the MERV rating, the more effective the filter will be at removing particles from the air.

How Often Should You Replace Your Air Filter?

Most manufacturers recommend replacing your air filter every 90 days. However, if you have a lot of people in the house, pets, or have particularly dusty or dirty air (smoking or under construction), it is recommended that you replace the air filters in a shorter interval, between 30 and 60 days. You can also set up a calendar reminder so that you don't forget to replace your filter ahead of time.

How to Replace an Air Filter

Replacing an air filter is as simple as finding the right size, opening the intake vent, and fitting the new air filter neatly into its slot. We also estimate annual costs for replacement filters based on manufacturer recommendations for when to change them.
