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. When you search for a filter most people search for the nominal size.

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.

# 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.

# 4 Consequences of 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 systems 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.
Find 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 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 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 requiring a costly replacement.
Dirt in The Duct Work- 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.

You will usually get a notice when your order is placed, when it ships and when it is delivered. We place so many orders online it is often hard to keep track of everything. With our emails so cluttered, we can easily miss these notifications. Although most orders arrive in 2 to 6 days anywhere in the county, sometimes weather and other factors can also cause delays.

The sooner you can check on it the better. Many delivery services such as Fedex and UPS have a time limit on when they can run a trace or enter a claim.
#8 Check Your Items as soon as they arrive: Wrong Part Received
Often times, we order air filters ahead of time to always have a backup when it is time to replace the filter. Many filter company's have had supply chain issues making it hard to finds certain filters so it is a good idea to have your filters before you need them. With many filters having similar items numbers it can be easily to order the wrong part. Since many companys have time limits on returns, it is a good idea to check the items part number as soon as it arrives, but do not open the item if it is factory sealed, this could void your return.
#9 Open Items: Void return rights
It is best to check the item number before opening any sealed parts. Many part numbers are very similar and ordering mistakes happen frequently. Opening the item or writing an installation day on an item may void the return rights as the item can no longer be sold as new even if it was not used. You would not accept a filter that had writing on it or was not in the manufacturer writing if it was supposed to be new, would you?
This can usually be avoided by double checking the item before you order, but occasionally the wrong item may also be sent, so it is a good idea to double check all of the number before ripping open factory packaging such as sealed plastic shrink wrap on an item or writing an installation date on the side of a filter.
