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".

    How to Find the Right Lennox Air Filter for You Using the MERV Rating System

    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.

    Buy Air Filters in Bulk and Save Money

    Most single filters packaged for retail are priced very high compared to the low price you can purchase quality filters in bulk.

In Comparison, the Atomic Brand 20x20x1 air filters which are sold in bulk as a case of 6 sells for $54.99 or $9.08 per filter.

    # 2 The Most Frequent Mistake Made is Buying the Wrong Filter: Nominal VS Actual Size

     The number one mistake you are likely to make purchasing filters online is purchasing the wrong size filter. This is a big hassle because you have to send back the incorrect filter, which may be a different price than the filter you needed, and could even cost you return shipping. You may need to wait for a refund and/or repurchase the correct filter. Understanding filter sizing can save you both time and money.

    How to get the right furnace filter size- actual size and nominal size explained

    Nominal Filter Size is the main culprit for incorrectly purchased filters. The Nominal Size is the dimensions used to Label the filter, but are usually rounded numbers and not the actual size of the filter. For instance, a filter's nominal size may be 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: Making the Correct Replacement Filter Purchase

    The actual size, as you may have guessed, is the actual dimensions of the filter by length, width and thickness. This size is usually 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 sometimes 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 insure a snug fit. Check to see if the filter list compatible brands and model numbers. These are usually in the filter descriptions and bullets of the filter detail page. On Amazon you can usually find this information farther down the product page below the fold or click the link for additional product details.

    # 3 The Most Costly Mistake, Using The Wrong Filter: How To Get the Right Filter?

    Find the Right Filter for Your System? An Explanation of MERV

    When considering the air quality in your home, you should consider an air filter with highest level of efficiency that is compatible with your HVAC system. Minimum efficiency reporting value, known as the MERV rating, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to rate the effectiveness of air filters.

    How to Compare Filters

    Comparing MERV ratings is a good way to begin to comparing filters. A Pleated filter with a rating of at least MERV 8 is better for airflow which is going to help your HVAC system operate more efficiently while still protecting your air quality.  Home Air Filters have MERV ratings that range from 0 to 16. Most new homes can support an air filter with a MERV rating from 8 to 13 filters, but MERV 15 and 16 filters require a system that can support the necessary air flow.

    Find Your Filter Brand and Model Number

    Depending on your HVAC sytems you may have return vent filters or a whole house filter. Vent filters, as pictured above are more straight forward to find the actual size and correct replacement.

    Buying the right 20x20x1 Air filter Atomic

    The image above is from an Atomic Filters 20x20x1 MERV 13 product listing. In addition to the filter having the Nominal size and actual size on the product image, the product title list the nominal size. The actual size for the filter is listed in the bullet points. Once you know what information to look for, making the purchase decision straight forward. 

    Whole house furnace filters often have compatible models across brands, but you need to insure that the replacement filter is compatible with your systems filter.This is best done by checking the product description to make sure your current filter model is listed.

    Find The Right Whole House Furnace Filter by Model number and brand

     You can usually find the proper replacement filter model  in your HVAC user manual. In the Amazon listing pictured for this Lennox Filter, you can see all of the information you would need to make the correct purchase.

    #1 Shows the Nominal Size of the Filter in product title along with the Brand.

    #2 Shows the Lennox Model number X6673 for this furnace filter.

    #3 shows other brands compatible model numbers this filter can replace.

     #4 shows additional details on the filter including the actual size of the filter. 

     

    # 4 The Effects of Using The Wrong Filter for Your System

    Using the wrong air filter over time could end up damaging the heating and cooling system itself. By reducing your system's efficiency, you could notice higher utility bills. When you use the wrong size air filter, or you install it incorrectly, the filter can’t effectively prevent dust from accumulating on the system’s coils motors and blowers. You’ll end up with a dirty furnace that can’t properly perform, and all of that debris could end up harming the system’s internal components.

    Use the Best Quality Home Air Filter for Your System 

    While you may think that using a more efficient filter with a MERV rating from 15 to 16 would be the smart option for allergy suffers and improved air quality, not every system is designed to work with these highly rated filters. If your system isn’t compatible, these filters will drastically restrict airflow. You can still have a high-efficiency filter, but make sure it’s one that is designed to work with your HVAC system.

    You can still have a high-efficiency filter, but make sure it’s one that is designed to work with your HVAC system.

    Using an air filter with too high of a MERV for your system can have a similar effect of a clogged air filter, if a filter becomes clogged, airflow will be reduced, which causes the fan motor to work harder. This means more energy is used, which will increase your utility bill. Eventually, the fan motor can burn out, resulting in overheating and failure of the entire system. Overheating can cause a heat build up around the heat exchanger in the winter which can cause the heat exchanger to crack. A cracked heat exchanger is a serious issue and needs to be replaced immediately to prevent system failure, fire or the release of carbon monoxide gas into the home.


    Dirty Air Filters Can Cost You Precious Dollars

    Having Dirty filters can allow components within the HVAC system to get dirty. This causes problems such as dust and debris on cooling coils, which can lead to freezing on the evaporator coils. Frozen coils block airflow, reducing the system’s ability to maintain indoor climate control which causes the system to work harder with less efficiency increasing your energy bill. Left unchecked, the system will fail and require a costly replacement.

    Dirty Air Filters can cost you money

    Remove the Dirt in The Duct Work- Remove the Dirt in Your Air

    Dirty air filters can lead to excess dirt that will end up in your ductwork, and you’ll need to have the ducts cleaned more frequently. Dirty ducts compromise air quality and some of the dirt can end up back in the HVAC system.

    #5 Try a Subscription for Your Furnace Filters and Save

    After you find the right air filter for your systems, consider getting a subscription and make it automatic. This will ensure your HVAC system is always protected from the most preventable causes of failure and you will have one less thing to remember. Companies often offer discounts on subscriptions saving you even more money.

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

    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 are 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 the 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 size and that it also has the foam to insure a snag fit.

    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.
