Overview
Nispira sells this as a two-pack of True HEPA replacement filters for 3M Filtrete room air purifiers, cut to 12 x 6.75 inches. It stands in for Filtrete part FAPF-F1-A and covers the FAP-C01-F1, FAP-T02-F1, FAP-C01BA-G1, FAP-T02WA-G1, FAP-ST02W and FAP-ST02N units.
Filter cost is what actually determines the running expense of a small room purifier, and on the Filtrete C01 and T02 units the F1 cartridge is the whole consumable. Buying two at a time covers most of a year for a typical household and lets you keep a spare on the shelf, which is the practical difference between changing a filter on schedule and running a clogged one for an extra month.
- 2-pack of True HEPA filters, 12 x 6.75 in
- Replaces Filtrete part FAPF-F1-A
- Fits FAP-C01-F1, FAP-T02-F1, FAP-ST02W and more
- Rated 99.97 percent at 0.3 microns
Who it's for
For owners of the Filtrete C01 or T02 family who want the same F1 cartridge without paying the brand-name price. It is a size-specific part, so a Filtrete unit taking a different filter code, or any other manufacturer's purifier, is out of scope. Households with pets, smoke or a dusty climate will burn through them faster and benefit most from the two-pack.
Pros and cons
- Two filters per pack for the price of roughly one OEM
- Cut to the F1 size, no trimming needed
- Individually wrapped so the spare stays clean
- Covers six listed Filtrete model numbers
- Only fits the F1 filter size
- Replacement interval can be short in dusty homes
- Third-party part, not a 3M product
Performance notes
True HEPA media is rated to capture 99.97 percent of particles down to 0.3 microns, which covers dust, pollen and smoke particulate. Replacement interval depends far more on your air than on the filter: dusty or desert conditions can pull the change window down to a couple of months, while a clean indoor environment stretches it considerably. The purifier's own change indicator is the practical guide.

Frequently asked questions
Does the Nispira F1 filter fit the Filtrete FAP-ST02W?
Yes. Nispira lists FAP-ST02W and FAP-ST02N alongside the C01 and T02 models as compatible with this 12 x 6.75 inch filter.
Is this the same as Filtrete part FAPF-F1-A?
It is a third-party replacement for that part number, made to the same dimensions rather than being a 3M product.
How often should the F1 filter be changed?
Follow the purifier's own filter indicator. Dusty or dry climates shorten the interval noticeably compared with typical indoor conditions.
