If it doesn't fit the model we list, we email a prepaid return label within 30 days of delivery and refund you in full; opened to test the fit is fine. Changed your mind? Return it unused in its original packaging within 30 days of delivery. The return label is free for these too.

We make what we sell.
Think Crucial started in 2007 at a family vacuum repair shop. Today we make aftermarket filters, bags and parts built to fit the machines you already own, plus our own descalers and cleaners. Most people can fit the part themselves. They just need the right one, and a way to check it first.

Full product description
A 3-pack of replacement pads for 16x25 Dynamic polarized-media air cleaners. Each pad is pre-cut to about 14.5 x 22.5 in. and drops into the reusable 16x25 frame. The frame isn't included.
Part numbers it replaces
- Dynamic C3P1625 and C3P1625R
- Service First FLR01771
- Lennox 85N53
- 54-16X25-R
Also compatible with: Rheem models 84-16X25-1; AirRanger models AirRanger 16x25 (3LPG1625C24).
What the pad is made of
Electrostatic fiberglass media around a carbon core. Handle the pads with gloves, since loose fiberglass can irritate skin.
How often to change it
Dynamic's schedule for its own pads is every 3 to 4 months. Three pads last 9 to 12 months on that schedule.
Questions
Is a 16x25 pad the same as a 16x25 furnace filter?
No. The pad is media only, cut smaller than the frame. It works in a polarized-media air cleaner's reusable frame, not in a standard filter slot.
Do I need to buy a new frame?
No. Keep your frame and replace the pad inside it.
My cleaner is a different brand. Will it fit?
It fits the Rheem and AirRanger models listed above, which use the same 16x25 polarized frame. For anything else, check that your frame is 16x25 and email support@thinkcrucial.com if you're unsure.
