About this item

• 【Broad compatibility across 4 fans models】These replacement filters is compatible with Shark air purifi-er 4-fan units—including HE400, HE401 (and variants HE401C, HE401NP), HE402 (including HE402C), HE405, and UA415—and are directly comparable to OEM part numbers HE4FKBAS, HE4FKPET, HE4FKPETMB, and HE4FKPRO
• 【(Main filter + activated carbon + pre-filter) 3-stage filtration】The filters employ premium main filter along with activated carbon and a pre-filter layer, effectively absorbing most of particles as small as 0.3 µm—like dus-t,poll-en,pet dand-er,and smoke
• 【Pre-filters included extend overall filter life】The pre-filter trap larger particles and help protect the main filter—thereby extending service life and stretching value
• 【Part Number Variations Indicate Odor-lock Features】According to user-sourced info, the HE4FKPET is labeled "Anti-Allerg-en HEPA Filter with Advanced Odor Lock", the HE4FKPRO adds "Fumes Lock", and HE4FKBAS is the base replacement HEPA filter—so the difference lies mainly in added odor/fume adsorption capabilities
• 【Replacement interval and usage reminder】 OEM guidance recommends filter replacement every 6–12 months, depending on air quality and usage, with a flashing FILTER LIFE indicator to notify when replacement is due. After installing a new filter, hold the FILTER LIFE button for 3 seconds to reset the counter
