How to Measure Your Filter
Steps 1 & 2
Measuring Length and Width (L x W). (If your filter is not a square, the smallest measurement goes first).
Step 3
Measure the thickness (Depth) of your filter from front to back.
Step 4
Put Your measurements together (L x W x D).
Actual Size
A filter’s true dimensions.
Example: 19.75” x 19.75” x 1”
Nominal Size
Rounded numbers used by manufacturers.
Example 20” x 20” x 1”

What is a MERV Rating?
MERV ratings let you know the efficiency and level of filtration that an air filter can handle under normal circumstances. The higher the MERV rating, the finer the particles are that are filtered our of the air in your home. Many air filter retailers use MERV or a similar rating to rate their air filters.
About MERV, MPR and FPR Rating
MERV Rating (Minimum Efficiency Reporting Value):
MERV Rating is the primary rating system used in the industry, both domestically and internationally. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV rates a filter’s ability to capture and hold particles and pollutants.
MPR (Micro-Particle Performance Rating):
MPR Rating is a rating system developed by 3M. It rates the manufacturer’s Filtrete product line and their ability to capture airborne particles smaller than 1 micron.
FPR (Filter Performance Rating):
FPR Rating is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color code and number scale (4 to 10) that closely resembles the MERV rating.
FAQs
When air passes through a 20x20x1 air filter, contaminants are trapped in its pleats, allowing it to capture dust, mold spores, and keep allergens from circulating in your home. It functions as a barrier to purify air and trap harmful airborne particles. When it's correctly installed, it will keep your system from getting clogged and allow you to breathe cleaner, healthier air.
Under normal circumstances, a 20x20x1 filter can produce cleaner air for 60 to 90 days, but it should be replaced every 30 days during summer and winter months to ensure proper filtration because your HVAC system is running more often. You may need to change the filter more often if your home has a lot of dust, smokers, pets, or family members with allergies. Check for obvious dirt and debris on your air filter to see if it needs to be replaced.
A filter with a MERV rating that balances filtration capacity with airflow is a wise choice when selecting a 20x20x1 filter. MERV 8 filters are capable of removing dirt, dust, and lint, while MERV 11 and 12 filters are better if you suffer from allergies or asthma and need finer allergens removed from your living area. The best choice for an air filter will depend on the amount of filtration your HVAC system can handle and the specific type of air quality you need.
Some 20x20x1 HVAC filters are more economical and environmentally friendly than others because they can be cleaned and reused. Not all filters of this size can be washed. Check the filter you plan to use to make sure it's capable of being washed and reused. Effective cleaning helps these types of filters properly trap particles repeatedly over time.
If you’re looking for a durable and energy efficient furnace filter, a 20x20x1 furnace filter is thicker than standard thinner furnace filters. Their larger surface area and dense pleated folds allow it to trap finer particles, and requires replacement less frequently than standard filters. Because it's a high-efficiency filter with low air flow resistance, it's less likely to clog or strain your HVAC system. In the long run, it's a more reliable solution for achieving healthier air quality than using a standard flat panel filter is.
Some HVAC systems are versatile and use the same filter size for both air conditioning and furnace systems, providing consistent filtration all year. Homeowners need to verify their HVAC system can support a 20x20x1 filter. Using the same size filter makes maintenance easier and ensures optimal performance. Check the slot in your HVAC system to make sure your 20x20x1 filter fits correctly into it.
