Can't Find the Right Sized Air Filter?

Standard size filters will fit the vast majority of filter frames, but you may have one of the millions that needs a custom size. You have come to the right place. Building custom size filters is one of our specialties. We do it right here in our Omaha warehouse.

Why Size Matters

You may be tempted to grab a filter off the shelf that’s “close enough.” But the purpose of air filtration is to keep your air as clean as possible. If the filter is the wrong size and allows air to bypass the filter, then you are not taking full advantage of your system. The air for your system – and your lungs – is not as clean as it could be.
