The Glasfloss MERV 10 Z-Line 28x28x1 air filters excel at removing allergens and dust from the air, making your home’s air cleaner. We designed the sturdy frame using heavy-duty, moisture-resistant materials, including recycled content, to make it easy to install and remove from your HVAC system. The synthetic fibers in the filter media won’t support mold growth or absorb moisture. By thermally bonding all parts together, we ensure extra durability. Choose these filters for their reliability and effectiveness in both homes and businesses.

About Air Filter Sizing

There are two main ways to refer to air filters: their Nominal size and their Actual size. The Nominal size is a simplified version of the dimensions of the filter and is how it is typically labelled and sold. The Actual size, however, is the exact dimensions of the filter. Some filters may have the same Nominal size, but different exact dimensions, which is why the actual size is important when it comes to ordering filters. For more information, please see our article "Nominal vs. Actual Air Filter Size”

MERV 10 Can Capture

MERV 10 Efficiency

MERV 10 air filters offer an upgrade from MERV 8 without making your system work harder or adding resistance. They are great for removing many allergens and providing better indoor air quality to your home or business.

How often should I change this air filter?

While we give an estimated life of each filter, how often your air filter needs to be changed depends on your individual situation. How many people live/work in your space, if you have pets, and even your location and time of the year can all affect how quickly your air filter gets dirty. We recommend checking your filter once a month to keep track of how dirty it’s getting. Check out our video explaining this in more detail on our “Air Filter Change Frequency” page.

Great buy!

Took a little longer than I would have wanted but a well worth it product. MERV 10, designed to be replaced every 3 months, ensures I have a filter in possession for the next 3 years. This helps ease not only having to constantly go out, but the price was on point as well helping to ensure future business with Air Filters Unlimited.

Would order again

I did not realize when I ordered that this was more of a specialty item because of the size. It was not from the other company I have used. But when they did come they were exactly what I needed.
