About this item

Product details

The under sink water filtration system effectively reduces silt, rust, large particles, fluoride, heavy metals, micron substances, turbidity and chlorine, thus improving water taste for direct drinking, coffee, or beverages. It retains natural minerals without reducing TDS.
  • [More filters, better taste] The three replacement filters represent three-guard household water lines, effectively reducing silt, rust, sediment, cyst, and large particles, heavy metals, turbidity, carbon, asbestos, and fluoride. Furthermore, the under sink water replacement filter can effectively reduce chlorine with WQA authority certification, improving water taste for direct drinking, coffee, or beverages. It doesn’t reduce TDS, but it retains natural minerals.
  • [No leaking or cracking with highly precised technique] The under counter water filter adopts strong materials with an upgraded design. In addition, the age-resistant and freeze-resistant materials make the system twice thicker. The system has also passed 400 psi burst pressure, 100,000+ pulse tests at 150 psi, and static tests at 300 psi. These tests prove that the durable integral design clears up worries about cracking cases and leaking issue.
  • [Lifespan of up to 18 months] The three filters have lifespans of 6 months, 8-12 months, and 12-18 months, respectively. This long lifespan eliminates the cost of purchasing and replacing filters every now and then. Under the premise of meeting the needs of a family of five at a go, the average daily cost is only 0.24 dollars. We help you save over 60% cost compared to buying bottled water.
  • [3min installation, 3s replacement] This water filter for sinks works perfectly with 3/8” and 1/2” cold water tubes. The overall installation process does not require the help of a plumber; it is a simple DIY. With innovative push-to-connect fittings, the installation takes less than 3 minutes, with no plumbing experience. In addition, the twist-and-lock design lets you replace each filter in just 3 seconds.
  • [On-demand filtration solution] The waterdrop filter connects to your original faucet, so that you don’t have to drill a hole. With a stale water flow, this filter provides all-round protection for drinking or usage.If you have any problems with the product, contact our 24/7 technical support without any worry!

Compact, easy to use, and fits right onto fauset

I love how compact this system is—it fits perfectly under the sink without cluttering my cabinet. The best part is that I didn't have to drill any holes in my wall or install a separate faucet thing. It connects directly to my current sink faucet line, so there is no need for a separate outer point on my counter. It's also incredibly useful because it shows the exact months when you need to change each filter. Since they all have different timelines, you don't have to change them all on the same day, which saves time and money!

Even an old lady can install it!

I have been using a counter top RO filter for a few months because I was unsure I could install and under sink filter like this. Anyway, I don't love the RO filter because of the demineralization and finally decided this device looked easy enough for me to install on my own. I did it with no links and no disasters! The package arrived quickly, the instructions were clear and most importantly, the water tastes great. I haven't had it tested or anything but our tap water doesn't taste too good and with this filter it is perfect for me.
