Difference between Stock and Made-to-Measure filters
Stock filters are identified by thier nominal dimensions. For example, a stock filter 20" * 20" will measure in reality 19-3/4" * 19-3/4". Made-to-Measure filters must be ordered with their real physical dimensions and not their nominal size.
We can add carbon to all our custom filters
If the filter you need is larger than the sizes of the form above, divide its length by two and use two smaller filters to fill the space instead. This tip can also be used when you aren't able to slide a very large filter into place because of the presence of a wall or other obstruction.
Frequently Asked Questions
-
What is a "MERV" rating?
MERV stands for minimum efficiency reporting value. MERV ratings are an air filter industry standard. The higher the MERV rating, the more particles are captured as well as the ability to filter smaller and smaller particles. While higher MERV ratings are better at filtering, air flow is reduced slightly. Residential furnace filters range from MERV 8 to 13.

How do I measure my air filter?
Measuring your air filter is easier than you think. One of the best ways to find the size of your air filter, is to check the outside of the filter to find the part number and size. On the outer frame, you will see at least one set of numbers. If you see two sets of numbers, the filter size needed to order replacements is the nominal size, not the actual size. You can ignore the actual size printed on your filter for this task, as the nominal size is the number set needed to order new filters. The other way to find the size of your filter is to measure it yourself. The measurements of the air filter go by length, width and depth. It’s also important to know that the length and width are interchangeable. For example, if your filter is 14 X 20 X 1, it can also be 20 X 14 X 1.

Which way does my air filter go?
Our filters are made and packaged to provide the correct instructions on the direction that your air filter should go in. Typically there will be an arrow on the side of the filter which will indicate which way to insert the filter. Some washable filters do NOT have an arrow on the side, because it doesn't matter which way they are inserted. If your filter has a wire backing on one side (ex. A pleated type), the wire backing goes on the DOWNSTREAM side when you install the filter
