A bulk box for households already committed to the Core 300 platform. Same cartridge as the two-pack, with the reorder cycle pushed out considerably.
A well-matched aftermarket cartridge for the Core 200S, two to a box. Confirm your unit is a 200S and not a Vista 200 before ordering.
An economical two-pack for the Levoit Core Mini that installs without fuss and includes fragrance sponges. Only worth ordering once you have checked your unit is a Core Mini.
A sound way to stock the C545 for several years at a fraction of the manufacturer's per-filter cost. Order carbon prefilters separately if odor control is part of why you run the unit.
A straightforward cost saving on a consumable that has to be replaced anyway, as long as your purifier takes the F1 size. Check the code on your existing filter before ordering.
The genuine filter for the newer Max series in this purifier size, trapping fine particles and light odors. It does not fit the earlier models in the same family.
The straightforward choice for keeping a PuroAir 400 working as designed, provided you accept that the recurring cost is high relative to generic alternatives.
A well-priced aftermarket Filter S set for the Winix C545 that includes enough carbon sheets to outlast the HEPA panels, making it the sensible default for that one model.
A close-fitting, lower-cost alternative to the OEM filter for the compatible models listed, reviewers advise double-checking your exact model and resetting the machine after installation.
The manufacturer cartridge for the Vital 100S-P, worth its premium mainly because it keeps the purifier's filter life tracking and sleep mode performance working as designed.
The correct consumable for a HAP605, bought as a pair so replacement never gets postponed. Straightforward, and there is no reason to gamble on a third party cartridge.
The right cartridge if you run a PX500, with genuine carbon rather than a token dusting. Plan on the 3-6 month cycle and order the next one before the current filter starts letting odors through.
