Gravity-fed countertop filter systems, portable RO and replacement cartridges from Purewell's own store.
Purewell's range centers on stainless steel countertop gravity systems (K, SS, SF and BO Series) that run without electricity, water pressure or plumbing. Purewell lists its K Series system at 2.25 gallons in 304 stainless steel with a built-in water level window, sized for 3–5 people. It also sells a rechargeable 10-stage portable RO system (model K8680) for camping, RV and emergency use, countertop and under-sink RO systems, and replacement filters.
Current codes (valid through 12/31/2026)
Gravity systems filter slowly, and Purewell states its K Series carbon filters do not reduce TDS; if dissolved solids are your concern, look at RO instead. Before buying, check the manufacturer-listed certifications and test documents Purewell posts for the exact model, and plan for filter replacement on Purewell’s listed schedule.

Ceramic replacement filters for Purewell K Series and SS Series gravity systems.
Two versions are sold: the 3-Stage Advanced (item K8013) and the 4-Stage Reduces PFAS (item K8091). One box holds two filter elements. The ceramic surface is reusable and washable rather than disposable.
Both versions fit Purewell K Series and SS Series gravity systems. The 3-stage and 4-stage versions differ in how many filtration stages the element carries, so pick the one that matches what you want the filter to do. Prices can change at the seller — confirm the current price and the version you are buying before you order.

Filter element specifications and replacement intervals vary. Consult current manufacturer documentation for the model you are considering.
Gravity is slow. A two-element system serves 1–2 people comfortably; add elements or choose a larger chamber for a family.
Review documentation for the exact model and understand what any published testing covers before relying on performance claims.
