The genuine part for a Vital 100, and worth staying with rather than saving a little on a copy, because the purifier's own filter-life indicator is calibrated around it.
A full year of filtration in one purchase for HPA300-series owners, and it quietly fixes the common mistake of replacing the HEPA while ignoring the pre-filters.
A two-pack that covers most of a year on PuroAir's own schedule, which is a shorter interval than most rivals ask for. Buy the pair rather than singles.
A sensible way to buy Honeywell's R filter if you own one of the HPA consoles, since the three-pack works out cheaper per filter than buying singles and covers about three years of annual changes.
If you own a Core 300, 300-P or 300S, this is the low-friction way to keep it fed. Same drop-in ring, same three-layer construction, two cartridges per box.
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.
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 straightforward choice for keeping a PuroAir 400 working as designed, provided you accept that the recurring cost is high relative to generic alternatives.
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.
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 reasonable third-party option for first-generation Pure Cool Link towers, provided you check your model first. The compatibility list is narrower than the product name suggests and is where most returns come from.
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.
Popular PickThe 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 genuine cartridge for the LV-H133 tower, and worth staying with rather than saving a little on a copy, because the purifier's filter-life indicator is calibrated around it.
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.
