MERV 11 air filters are designed for homes with allergies and in some cases, asthma. Those with respiratory illnesses or compromised immune systems may benefit from MERV 11 air filters due to these filters being significantly more powerful than alternative MERV filters at capturing smaller particles, such as MERV 8.

No. Using a 20x20x5 air filter instead of a 19x20x5 air filter can cause significant issues with your HVAC system and furnace. A 20x20x5 air filter is too wide for systems designed for a 19x20x5 air filter. This will result in air leaks and reduced filtration, allowing more dust and harmful particles into your system than necessary. Always measure the exact size of your media cabinet or compare old filter labels to ensure you find an air filter that is just right.
The actual size of a 19x20x5 air filter measures in at 19.06 x 19.81 x 4.25 inches. Manufacturers label filters by typical sizes for easy reference. However, it's important to ensure the measurements are proper for a snug fit inside the media cabinet itself.
This specific air filter size is suitable for certain whole-house air cleaner models and HVAC systems. You'll need to confirm that your furnace system is compatible with the air filter you choose. Brands such as Aprilaire and Honeywell have systems that are designed for the 19x20x5 air filter.
No, systems designed for 19x20x5 filters handle MERV 13 without airflow problems. Deeper pleats in a 5-inch filter, such as the 19x20x5 air filter, allow for stronger particle capture while ensuring static pressure remains low. This helps boost your HVAC system's overall energy efficiency while preserving its performance.
You can buy 19x20x5 replacement filters online from air filter retailers like Filter King. Filter King currently carries MERV 8, 11, 13, and MERV 8 Carbon filters with fast shipping, bulk order options, and a subscription model in place. Our subscription-based model ensures you receive your filters routinely to avoid allowing your filter to become too clogged and/or inefficient. When a filter is clogged and requires a replacement, it can reduce the efficiency of your filter and the airflow in your home.
No, never cut air filters to fit your system. Cutting the frame of an air filter can significantly cause major bypass air leaks. Additionally, cutting the frame manually reduces overall effectiveness at maintaining healthy air in the home. Purchasing a correctly sized filter (19x20x5) ensures a proper cabinet fit and full filtration coverage. The right sized filter helps streamline the process of installation. Whether you prefer filters for Bryant Carrier, Lennox, or Honeywell, you'll want to verify the measurements of your filters before making a new investment.
19x20x5 filters may cost slightly more or be similarly priced to common 5-inch sizes due to specialized production. Buying in bulk provides a significant value, especially if you prefer to have your filters delivered on time when you require replacements. At Filter King, purchasing in bulk is the fastest way to reduce the initial investment cost of a 19x20x5 air filter.
Many Honeywell whole-house air cleaners use 19x20x5 filters, but not all models. The Honeywell F100 and F200 models are suitable for the 19x20x5 air filter. Always reference your system's model number or if you have it available, your user's guide to confirm compatibility before purchasing a new filter and attempting to install it on your own. Before installing your new filter, be sure to check for properly printed arrows on the exterior frame for optimal airflow and filtration performance.
