Specs

Dimensions	7.25 × 8.5 × 1.625 in (DiscountFilters). FiltersFast lists 9.25 × 7.5 × 1.5 in for its H55-C — the aftermarket sources conflict; verify against your old filter.
Replacement interval	Replace every 3 months (FiltersFast); filter life 4–6 weeks (FiltersFast specs); at least once per humidification season (DiscountFilters).
Treatment / media	Anti-bacterial treated (DiscountFilters).
Quantity note	HWF-45 note: the HWF-45 fitment (HM-1550, HM-1555) is served by this same wick per the BestAir Pro and RPS charts — HWF-45 had no standalone retailer product page, so it is carried here as an alias rather than its own record.
