Returns and Exchanges

At, we want to ensure you're happy with your filter purchase. That’s why we work hard to ensure you’re always 100% completely satisfied. However, in the unlikely event you need to make a return or exchange, we’re ready to make it right.

As an extra layer of confidence when shopping with us we offer an industry exclusive Filter Fit Guarantee™

  • Keep in mind that because some of our filters are custom made, we cannot offer a refund or exchange (remake) unless a product is defective. Please review the "Custom and Exact Filters" policy below.
  • If there is a defect in material or workmanship, something doesn’t work properly, or your filter(s) is made in the wrong size and doesn’t fit due to an error made at our production facility, you can return it and we will replace or repair the same product in the same size you ordered at no cost to you for up to 30 days from the date of purchase.
  • We also offer free remakes on “oops!” orders where customers have made an error in measuring their filters. Please review our Filter Fit Guarantee for more details.

Should you want to return filters for any other reason (say, you need a different MERV rating, model, etc.), you can request a remake of the same same size you originally ordered at the same price you paid (including any discounts).

Don't Want To Exchange - Request Refund Only

If you would like to return the filters ordered but choose to not do an exchange for a different model and/or size please contact us for an RMA.

  • Once the RMA is approved you will be given the option to return the filters using a carrier (USPS, FedEx, UPS) of your choice or we can provide a pre-paid FedEx return label that will be deducted from your refund.

How to Avoid Measuring Mistakes

We all make mistakes. That’s why we give you the tools you need to help avoid common measuring errors. Filter size specifications and step-by-step directions on how to measure your filters are available on, or take a look at our how to measure your filter page or videos.

And don’t worry. If you do have an “oops!” moment and need to return your filters due to a measuring mishap, our Filter Guarantee Team is here for you! Just send us a photo showing how it doesn't fit, along with your corrected measurements, and we’ll remake your product for free!

  • Be sure you have measured your existing filter before placing an order, some manufacturers undercut filters so you should never base it off the label.
  • Exact/custom filters are not eligible for returns or exchanges.
  • Manufacturing tolerances of plus 0, minus 1/8" will be observed on overall width and length of custom/exact filters.
  • Pictures are used as a reference, sizes will vary.
  • Filters larger than 25x30x1 are considered a double filter where there is additional strength down the middle of the filter.
  • It's our policy to list the smallest dimension first on custom/exact filters. When the filters arrive the label will be displayed as such, this will not impact compatibility - it's just a matter of how you hold the filter.

If you have questions or concerns please contact us.
