About This

  • [Easy DIY Compatibility] This 3-stage under sink water filter system does NOT reduce TDS and helps retain beneficial minerals. Designed for standard under-sink cold-water connections and municipal tap water. Not suitable for hot water or well water. It connects directly to most faucets with 1/2" or 3/8" FEMALE NPT threads. Need to connect to a quick-connect faucet? Contact Waterdrop for free adapter fittings. No additional faucet is included
  • [Easy Filter Replacement] Replacement filters are easy to find and install. For WD-TST-UF/TST-UF-B 3 stage stainless steel under sink water filtration system, search B0D91M9322 for WD-P1, B0D91VJ8ZK for WD-U2, and B0D91VQ298 for WD-C3
  • [Efficient Filtration & Better Taste] This under sink water filtration system elevates your water game, giving you a taste that's better than your run-of-the-mill bottled water. And forget about that pricey coffee joint—brew up java at home that'll knock your socks off. Plus, if you've got a little one, whip up some delicious milk powder or drinks in a jiffy
  • [Simple Installation] Hook it up directly to your 3/8" or 1/2" home water pipe. If you're a DIY pro, you'll breeze through setup. Not a handyman? No sweat—we've got handy installation videos and instructions, plus our customer service team is on standby to answer any questions

  • [Long Filter Life And More Good For The Environment] These filters are built to last. The PP filter goes strong for 6-8 months, the UF filter for a year, and the CT filter for 12-24 months. Plus, by cutting down on plastic casing changes, we're saving Mother Earth from 500,000 pounds of waste each year—that's enough space to plant 20,000 trees
  • [Filters Large Volume Of Substances] This under sink water filtration system has 6 layers of top-notch filter materials, including a precision ultrafiltration membrane that can reduce impurities larger than 0.01 microns. Say goodbye to chlorine, heavy metals, funky odors, and more

  • [High-Quality And Sturdy Materials] Crafted from tough, lead-free 304 stainless steel, this undersink water filter system is built to last. Plus, it's got a sleek look and a thick sealing ring to keep leaks at bay. And did we mention it's saving the planet from a boatload of plastic waste?
  • [Note! Cannot Reduce TDS] Just a heads-up—this under sink water filter system won't reduce TDS. This under sink water filtration system will retain some beneficial minerals for our bodies, such as potassium, calcium, sodium, and magnesium. And hey, we're keeping it natural with coconut shell raw materials. But if you've got a coconut allergy, steer clear
