Full Review

The SpringWell CF1 is a compact under-sink carbon filter that connects directly to your kitchen faucet. It uses catalytic carbon and KDF technology to remove a wide range of contaminants at an accessible price point.

The standout feature is its PFAS removal capability — increasingly important across the EU following the 2025 PFAS regulations. It also effectively removes lead, chlorine, chloramines, VOCs, and sediments.

Installation is DIY-friendly. The kit includes everything you need, including a dedicated stainless steel faucet. Filters last approximately 9 months depending on usage — significantly longer than pitcher filters.

An excellent middle-ground for people who want better filtration than a pitcher but aren't ready for the investment of a full reverse osmosis system. Particularly recommended for areas near industrial or agricultural zones across the Mediterranean where PFAS contamination is a growing concern.
