This is a genuine OEM Wellis Crystal Micro Plus antimicrobial filter with manufacturer number AKU3001.\u003c\/p\u003e\n\n\u003ch4\u003eDoes the AKU3001 replace the AKU0135?\u003c\/h4\u003e\n\n\u003cp\u003eYes. The AKU3001 is the current blue antimicrobial filter that cross-references the earlier Wellis AKU0135. Always compare the dimensions and slotted coarse-thread connection before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the difference between AKU3000 and AKU3001?\u003c\/h4\u003e\n\n\u003cp\u003eThe AKU3000 and AKU3001 use the same coarse-thread fitment. The AKU3000 has white standard filter media, while the AKU3001 features blue antimicrobial media.\u003c\/p\u003e\n\n\u003ch4\u003eWhat does antimicrobial filter media do?\u003c\/h4\u003e\n\n\u003cp\u003eThe antimicrobial treatment helps inhibit microbial growth on the filter material. It does not sanitize the spa water or replace chlorine, bromine or another approved sanitation system.\u003c\/p\u003e\n\n\u003ch4\u003eWill the AKU3003 fit instead?\u003c\/h4\u003e\n\n\u003cp\u003eNo. The similarly sized AKU3003 uses a fine-thread connection. It should not be substituted for the coarse-thread AKU3001 unless Wellis has specifically confirmed compatibility with your filtration system.\u003c\/p\u003e\n\n\u003ch4\u003eShould I remove the band around the filter?\u003c\/h4\u003e\n\n\u003cp\u003eNo. The supporting band is part of the filter’s construction and should remain installed.\u003c\/p\u003e\n\n\u003ch4\u003eWill this fit every Wellis spa?\u003c\/h4\u003e\n\n\u003cp\u003eNo. Wellis uses several filter sizes and connection styles. Confirm the filter number, physical dimensions and slotted coarse-thread connection before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eHow many filters are included?\u003c\/h4\u003e\n\n\u003cp\u003eThis listing includes one genuine Wellis filter cartridge.\u003c\/p\u003e\n\n\u003ch4\u003eCan this filter be cleaned?\u003c\/h4\u003e\n\n\u003cp\u003eYes. Rinse carefully between the pleats with a garden hose and periodically use a dedicated spa cartridge cleaner. Thoroughly rinse away all cleaning solution before reinstalling the filter.\u003c\/p\u003e\n\n\u003ch4\u003eWhen should the filter be replaced?\u003c\/h4\u003e\n\n\u003cp\u003eReplace the cartridge when the pleats become torn, collapsed or permanently restricted, or when proper water flow cannot be restored through cleaning.
