Tips for Measuring Filters
To make sure your custom filters fit right the first time, here are some tips from the RememberTheFilter.com filter measuring experts:
- Never just assume what is printed on your old filter is the exact size. Measure your existing filter down to 1/8" for both the length and width and use those measurements for your new ones.
- Check out our "How to measure your air filter" page for more information on getting the perfect fit.
Still a bit nervous? Start by ordering just one case of filters if you need multiple sizes before ordering for your entire system. That way you can see how quickly your custom filters are delivered (for FREE, BTW) and how perfect they fit, so you can order more with confidence!
If you have any questions about measuring your filters before placing your order, call our Customer Care Team. We’re here to help you get the perfect fit, every time!
* The only time you may incur a remake charge is if there is a difference in price between the original product and the remake.

Custom Size Filter Disclaimer
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 filter. Picture is 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. 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.
