Choosing the Correct Filter

With dozens of filters to choose from, you need help to find
the right one for your home. Here are the basics:

To make sure you’re getting the right air filter for your central air system, make sure you know some of the basics:

Start with Filter Size

A filter that’s too large for your HVAC system will basically be as useless as a brick. Check your system’s user manual – it’ll tell you what size filter you need.

Check the MERV Rating

MERV stands for “Minimum Efficiency Reporting Value,” and it tells you how good an air filter is at getting rid of pollutants and contaminants from the air. First – look for the MERV rating. No filter should be without it. Then, check the number. MERV ratings are on a scale of 1-to-20, with 20 being the best you can get.

Check the Air Filter Media

This is the most important part of the air filter – the non-woven fabric that catches nasty stuff in the air so you don’t end up breathing it in. Pleated, fiberglass, plastic, and activated carbon are the most common, with the latter often considered the safest filter media.

Air Filter Buying Guide

Size. Efficiency. MERV rating. Just how many contaminants the filter catches. These are all considerations (along with your budget) that go into buying an air filter. Check out our article for a full rundown thathelps you choose well.

What Are the Best Air Filters?

That’s a difficult question to answer because we can approach it from so many directions. Which has the best MERV rating (that would
be the best for eliminating pollutants)? Which is best for your budget? The answer varies depending on your situation. But never fear – Air Filter Today stocks filters from every major brand so you’re sure to find what you need.

When Should I Change My Air Filter?

Most manufacturers make the same recommendation – once every
90 days. You can do so more often. Changing it every 60 days means less build-up so your filter doesn’t lose its effectiveness. But once every 90 days is enough for most homes.
