This page carries 3M Aqua-Pure inline water filters and replacement cartridges. The AP431 is the replacement cartridge for the Aqua-Pure AP430SS system and is rated to last 6 months. The page also carries the AP717 inline system and the IL-IM-01 inline cartridge.
An Aqua-Pure inline system and an Aqua-Pure replacement cartridge serve different needs: a system is a complete filter unit, while a cartridge refills a system you already own.
If you already own an AP430SS, choose the AP431. Check the product page of the AP717 or IL-IM-01 for its specifications before ordering. Packaging may carry 3M or Solventum branding.
The life of an Aqua-Pure inline filter depends on the product. The AP431 cartridge for the AP430SS system is rated for 6 months. For the AP717 and IL-IM-01, check the product details and the instructions that come with the filter.
The 3M Aqua-Pure AP431 is the replacement cartridge for the Aqua-Pure AP430SS system. Replace it every 6 months. Shopping for a different setup? See our 3M Aqua-Pure under sink filters or 3M Aqua-Pure whole house filters.
