By Plumzoo · Posted October 2, 2026. Price confirmed at Woot on October 2.

5-stage reverse osmosis system rated to remove up to 99.99% of lead, chlorine, fluoride, PFAs/PFOs, arsenic and more
Includes a 4-gallon (3.2 gallon capacity) storage tank, tank stand, chrome faucet, and a full extra set of filters for the first year
No electricity needed; fits 3/8" and 1/2" under-sink connections and runs on 40-80 psi water pressure
NSF-certified by an independent lab; includes filter housing wrench for DIY installation
Not available for shipping to Alaska, Hawaii, PO Boxes, or APO addresses

This is a straightforward DIY under-sink RO setup with a full year of included filters, which is where a lot of the value is since replacement cartridges add up. $95.89 against the $232.17 reference price is a solid price for a 5-stage system with a tank and faucet included, but note the shipping restrictions and that it carries only a 90-day Woot warranty rather than a longer manufacturer one.
