Description
This is our custom-size MERV 10 pleated air filter — built to your exact dimensions in any size you need, down to 1/8 inch increments. When your HVAC system has a non-standard filter opening, stock nominal sizes leave gaps that let unfiltered air bypass the filter. Custom sizing closes that gap.
When a custom filter is the right call
- Legacy air handlers with non-standard filter openings
- Commercial rooftop units with manufacturer-specific filter slots
- Residential returns that don’t match today’s nominal sizes
- Replacement for a filter you’ve been trimming or stacking to fit
- Built-in filter housings where the air handler was designed around the filter
What MERV 10 captures
Finer household dust, most pollen, mold spores, pet dander, and larger bacteria-sized particles — a practical step up for allergy-sensitive homes, wildfire-smoke regions, and light commercial spaces. Mechanical (not electrostatic) capture means performance doesn’t fade as the filter loads.
How to order
Measure your existing filter (not the housing it sits in — filters are typically slightly smaller than the housing for installation clearance) to the nearest 1/8 inch in length, width, and depth. If you’re unsure about measurements or which filter spec is right for your system, contact us with a photo of your existing filter or housing and we’ll confirm before production. Our Filter Fit Guarantee means if you measure wrong, we’ll remake the filter at no additional cost.
