Frequently Asked Questions
What size is the Hunter H-SW625 wick?
Hunter Pure Air's product page for H-SW625 lists equipment fitment (HPH625, HPH625-SGS, HPH625-WHS, HPH625-BLS, HPH625-GRS) but does not publish filter dimensions, and we will not quote a dimension we cannot source from the brand. detailed information please contact amanda@ntdeli.top — or send us the old wick and we will measure and quote against it.
Are the legacy PermaWick dimensions on retail sites reliable?
Treat them as indicative only. Figures such as 4-3/4 x 6-1/4 x 1-3/8 in for part 31941 and 9-3/4 x 8 x 1-1/2 in for part 31943 circulate on third-party retail listings and we have not been able to match them to a Hunter document. We list them on this page marked as unverified, and we always confirm against a physical sample before tooling.
Which Hunter units does the H-SW150 fit?
The H-SW150 is the wick for the Hunter Aspire Evaporative HHE150 4.8 L humidifier. Note that Hunter's own /products/h-sw150 URL returned a 404 when we checked it on 3 September 2026, so current retail availability of the genuine part may be limited — which is usually the point at which distributors start looking for an aftermarket source.
Can you match the PermaWick synthetic construction?
Yes. PermaWick-style parts use a synthetic rather than a cellulose substrate, which is what gives them their longer wet-life. We produce both constructions; for a Hunter replacement we would normally match the synthetic build so the service interval the end user is used to does not change.
What do you need from me to quote a Hunter part?
Either a physical sample of the old wick, or the Hunter model number plus three measurements (height, width, depth) taken at the filter cavity. Sample lead time is 7 to 10 business days from drawing approval. MOQ is 500 pieces per size.
