[Installation Pre-Check Notice]:This Philips 400G tankless under-sink RO system requires an electrical outlet under the sink. Power is required to maintain steady continuous water flow. Unlike traditional tank-style RO systems that store pre-filtered water inside a tank, our tankless model delivers filtered water instantly by electric-powered operation, with no waiting time and no risk of stale water stored in the tank.You also need a sink/countertop hole for the RO faucet (drilling required if no pre-existing hole). Included drain saddle only works with standard drain pipes. Please verify your kitchen setup before ordering.

[𝐀𝐪𝐮𝐚𝐩𝐨𝐫𝐢𝐧 𝐈𝐧𝐬𝐢𝐝𝐞 𝐑𝐎 𝐅𝐢𝐥𝐭𝐫𝐚𝐭𝐢𝐨𝐧]: Powered by Aquaporin Inside technology, this Philips reverse osmosis system uses aquaporin proteins—nature’s own water channels—in the RO membrane to create a biomimetic filtration process. It supports efficient water passage and deep 0.0001-micron RO filtration, helping reduce TDS, chlorine, particulates, taste and odor, lead, chromium III, and calcium. Technology tested in collaboration with NASA and ESA
[4𝟎𝟎 𝐆𝐏𝐃 𝐅𝐥𝐨𝐰 & 𝟐.𝟑:𝟏 𝐋𝐨𝐰 𝐃𝐫𝐚𝐢𝐧 𝐑𝐚𝐭𝐢𝐨]: With a 2.3:1 pure-to-drain ratio, this Philips under sink RO system makes 2.3 cups of filtered water per 1 cup of drain water, while traditional 1:4 RO systems send about 4 cups to drain per 1 cup filtered—up to 9.2X water-saving efficiency. The 400 GPD fast flow fills an 8 oz cup in about 11 seconds, ideal for drinking, cooking, coffee, and bottle filling
