How to Get The Right Filter Size Lennox Furnace Filter

When it comes to filters both size and compatibility matter. It is however important when looking for a compatible filter to understand filter sizing to make sure it is compatible with the exact model. First, you need to consider the actual size of the filter and make sure its actual dimensions match the filter you are replacing. Air filters are generally listed by their nominal size which can cause some confusion with consumers.  What you might not realize is that filters are not sold by their actual dimensions. Instead, a rounded up number is used to label filter packages. This measurement is referred to as the "Nominal Size".

    Home Air Filters: What You Need to Know About Air Filter Simplified

    We are going give you a simple way to pick the right air filter for your home because choosing the best air conditioner filter for your allergies can sometimes be a confusing task. The simple reason is that most people are not experts on their heating and air conditioning systems and generally rely on the recommendation of the company that services their HVAC (Heating Ventilation Air Conditioning) equipment.

    What contaminants are in the air in my home

    What Type of Air Filter do I Currently have In My Home?

    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 filters 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.

    Nominal Vs. Actual Sizes: Finding the Right Air Filter Size

    Buying the Correct Size Air Filter- The Most Important Thing to Know 

    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 16x20x1. These dimensions are a rounded value on the filters actual measurements. The actual measurements on this filter may be 15.5x19.5x.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 are 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 you 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. 

    Lennox Air Filter X0851 with Foam strips

    Examples of Nominal and Actual Sizes

     Size  Example 1  Example 2
    Nominal Size 20x20x1 16x20x1
    Actual Size 19.5x19.5x.75 15.75x19.75x.75

     

     Furnace filters should fit securely but should not have to be forced into position. If you have to force the filter into its slot, then it is probably too big. Forcing an improper filter size in a filter can cause it to buckle, damaging the filter or reducing its ability to function properly. Filters are a smaller than their slot to allow for easy replacement. Some HVAC units may need a filter with dimensions that are unique or uncommon. In these cases, a custom filter needs to be ordered.
