The Waterdrop TSB is a three-stage under-sink water filter that uses KDF media and a fluoride-reduction resin to cut silt, cysts, heavy metals, fluoride, and PFAS while keeping beneficial minerals. It delivers a high 1.7–2 GPM flow through a dedicated lead-free brushed stainless steel faucet and is IAPMO certified. Filters last 8–12 months, and the twist-and-lock design makes DIY replacement simple. It suits homeowners who want cleaner drinking water without the wastewater and slow flow of reverse osmosis, though it does not soften water.
