Key item features

  • Composite Filtration. iSpring US15SD under sink water filter system is a single-stage direct connect design with high capacity multi-layer filtration. US15SD's composite filter cartridge can effectively reduce lead, chlorine, smell, bad taste, heavy metals, sediment, and other large particles while keeping healthy minerals in your filtered water. The filtration does not lower TDS but will retain useful minerals.
  • Long Life Service & Multiple Use: The filter system has long service life for drinking, cooking, and cleaning. The composite multi-layer filter can filter water down to 3 microns. It works great with standard kitchen or bathroom faucets. Fits 1/2" NPT or 3/8" Comp threads with included adapters. Durable metal bracket and quality braided stainless steel hoses. Filter change is a breeze.
  • Innovative Design: The direct connect under the counter water filter has an easy DIY installation design. It only takes you a few minutes to finish installing. The filter replacement process is easy. With our new concise design and suitable size, the filter system can perfectly fit into any place at your house. The system should be connected only to a COLD WATER supply.
  • Cost-Effective: Average 8-12 month filter service life and only filter cartridge need to be changed. iSpring US15SD helps you save filter replacement costs to better protect the environment.
  • Leak-Free improvement: Our new version adapter and O-rings design prevent water leaks more effectively. US15SD treats water effectively with the high flow right with minimal pressure drop.

I don't usually give 5-star reviews. On this one, how could I not? 1. This model uses off-the-shelf replacement filters, which saves a ton of money over the rival models that make you buy their exclusive (expensive!) ones. 2. I'm no plumber but it was easy to install. 3. One reason it was easy was their attention to little details, like telling you how much clearance to leave above and below when mounting so you can easily change the filter and parts adaptable to an older hose setup. Overall excellent instructions. And the water tastes fine. A lot depends on what kind of replacement filter you pick in the future but like I said, this one lets you choose.
