Air Filter Terminology:

What is the Difference Between A Home Air Filter and Furnace Filter?

The terms can be confusing but basically, people in different parts of the country refer to the same filters based on the type of primary system they use. In the North, you have Furnaces and South you use the Air Conditioner. Air Filters or Furnace Filters are also known as AC Filters, Air Conditioner Filters, HVAC Filters or Cold Air Return Filters.

Air Filters are the same thing as Furnace Filters and are also known as AC Filters, Air Conditioner Filters, HVAC Filters or Cold Air Return Filters.

Where is My Air Filter Located?

Homes with central heating and cooling systems have an air filter to protect the equipment and may have higher efficiency rated filter to protect the air quality in the home. The filter location on some HVAC systems can sometimes be more difficult to find. The air filter is can be located in the return air duct or blower compartment before the return air reaches the air handler.

You may have several returns in your home and each has an air filter. You also may have a single whole house filter that can be around 3 to 6 inches located in a filter cabinet, it should be next to your furnace or air handler.

What is MERV and How do I uses it to Choose the Best Filter?

The MERV (Minimum Efficiency Reporting Value) rating system was designed to help tell how well an air filter removes particles from the air. What is MERV rating of the filter in your home? You may not even know because, more often than not, the company that services your HVAC system replaces the air filters during the service call. Each air return has a grill that opens so that you can replace your air filter. Depending on the size of your home you may have one air return to several. When replacing filters I see a lot of contractors use a cheap flat panel air filter with no MERV rating or a very low MERV rating. I have asked contractor many times when they put that filter in over the years and the answer is always the same. "This is the kind of air filter and I use is my self, those expensive air filters are a waste of money". Most people do not know much about how their HVAC system works so they just rely on what their contractor says. Basically, all these cheap air filters do is protect your HVAC equipment from large dust and lint. Essentially the cheap air filters with no MERV ratings can be so porous that particles that can damage your HVAC equipment, can pass right through the filter. Good air filters can protect the air quality in your home and do not have to be expensive.

What MERV filter should I use?

1. Find the Right Filter Rating: MERV(Minimum Efficiency Reporting Value) is a rating system for air filters create by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) to measure the efficiency of air filters. Some companies use their own rating system such as Home Depot uses FPR (FILTER PERFORMANCE RATING) and 3M uses MPR(MICRO-PARTICLE PERFORMANCE).
2. MERV 8 (comparable to MPR 600 and FPR 5) is a good level to begin to protect air quality in your home. MERV 11( Comparable MPR 1000-1200 FPR 7)and MERV 13(Comparable MPR 1500-1900 FPR 10) are used in superior commercial buildings and in homes with allergy sufferer. MERV 15 and MERV 16 are among the top residential air/furnace filters available.

Some companies use their own rating system instead of the MERV rating system. Home Depot uses FPR (FILTER PERFORMANCE RATING) and 3M uses MPR (MICRO-PARTICLE PERFORMANCE).
2. MERV 8 is comparable to MPR 600 and FPR 5 and is a good level to begin to protect air quality in your home. MERV 11 is Comparable MPR 1000-1200 FPR 7. and MERV 13 is Comparable MPR 1500-1900 FPR 10 and are used in superior commercial buildings and in homes with allergy sufferer.

How Often Should I Change My AC Filter?

General pleated AC Filters are changed every 2 to 3 Months Depending on use. Environments with Smoke, heavy dust (ie Desert) or pets may need more frequent air filter changing.

Cheaper flat fiberglass filters may require changing every 30 days and may even be labeled as a 30 day filter.

Whole House AC Filters with a size from Approximately 3 to 6 inches in width can have a life spans as long as 6 to 12 months depending on environmental conditions.

Air Filter Sizing: Nominal VS Actual Size

When you are buying your air filter online most important thing to know is Air Filters have two sizes that you need to understand the Nominal size and the Actual Size. Not understanding these numbers often leads to consumers purchasing a filter that does not fit their Furnace or HVAC system.

Nominal vs Actual air filter size by Atomic


Understanding Nominal Filters Size Could Save You Time and Money

Not understanding the Nominal Filter Size is the primary culprit for incorrectly purchased filters. The Nominal Size is the usually the dimensions used to Label the filter. For instance 10x20x1. These dimensions are a rounded value on the filters actual measurements. The actual size measurements on this filter may be 15.5x24.5x.75, but that could vary by brand and manufacturer. So in order to make sure you have the correct size filter, especially if you are replacing with a different brand it is important to confirm the actual size on the filter. When purchasing filters on the internet the Nominal size is usually found in the product title.

Actual Filter Size- The Key to Making the Right Replacement Filter Purchase

The actual size as you might have guessed is the actual dimensions of the filter by length, width, and thickness. This size is often on the filter right below the Nominal size and is usually labeled as the actual size. When you are buying a filter online the actual size is sometime in the product bullet point or the product description. If your filter does not have actual dimensions on the outside of the filter, you can measure your filter to get the correct dimensions. Some brands have a foam gasket on the outside of the filter, in this case, you will want to make sure you have a compatible actual size and that it also has the foam to ensure a snug fit.

How Do I Find the Size of My AC Filter?

You can usually Find the Size of Your Air Conditioner filter right on the size of the frame of the filter. The Picture of this 10x20x1 inch air filter has the Nominal size which is the size by which air filters are generally sold. On the right of the filter, it also includes the actual size of the filter which are the true measures dimensions of the filter by length width and depth. See air filter image:

If there is no size on your current AC filter, you can measure the length width depth of the filter and the filter to find the Actual Size of your filter with the Corresponding Furnace Filter size in the Furnace Filter Size.

What Kind Of Air Filter Do I Need to Protect the Air in My Home?


According to the EPA, indoor air quality(IAQ) can be 200% to 500% more polluted than the air outside. In Order to protect the air in your home, the EPA says air filter rating of MERV 7 to 13 is needed. Air filter rating of 1 to 6 are basically to protect the HVAC equipment.

Super Charge Your 10x20x1 Air Filters

You can proactively clean the air and surfaces in your home by adding an In Duct Air Purifier that creates supercharged particles. The iWave uses patented technology, called needle-point bi-polar ionization, to create equal amounts of positive and negative ions. When these ions are injected into the air stream, they break down passing pollutants and gases into harmless compounds like oxygen, carbon dioxide, nitrogen and water vapor. This is the same compound created by thunderstorms and waterfalls in nature and helps purify the air. Aerosolized ions are effective in reducing bacteria, viruses, odors, and other contaminants that exist in the air you breathe inside your home.This creates charged particles which will attract to other particle in the air for better filtration when using electrostatic filters.
