iSpring US21B Heavy Duty 2-Stage Undersink Water Filtration System with 10” x 4.5” GAC+KDF and CTO Carbon Block Filters, 1” Ports
About this item
- [Heavy Duty Water Filter System] Made of quality material for all components and equipped with 10” x 4.5” filters, this heavy duty undercounter water filter system is designed to provide you and your loved ones with a continuous on-demand supply of refreshing water whenever your kitchen faucet is on. No waste water. No tank taking up your under sink space.
- [10"x4.5" Filters] 1st stage KDF plus GAC carbon filter(FG15B-KS) and 2nd stage CTO carbon block filter(FC15B) can remove up to 99% of contaminants, including chlorine, lead, mercury, and many other heavy metals. They also tackle problems like turbidity, cloudiness, colors, bad taste, and odors(e.g. hydrogen sulfide that smells like rotten eggs). A true shield that protects you and your family from ingesting harmful chemicals or contaminants in your tap water.
- [Steady Water Flow] Thanks to the system’s connection design and its 1” inlet and outlet ports, you will experience less waiting time when filling up your glasses, pitcher, coffee pot, or cooking pots as the peak water flow rate is up to 15 GPM. Based on the contaminant levels in source water and your water use, we suggest that you change your filters every 6-12 months for ideal filtration performance.
- [Easy DIY Installation] Comes with two 24-inch DIRECT CONNECT hoses that connect the system to the existing under sink incoming water supply and the cold water line of your kitchen faucet. Unlike reverse osmosis systems, you don’t need to spend time drilling a hole on your countertop for a RO faucet. Tool free. No mess. System installation and filter cartridge replacement are a breeze!
- [TDS Note] Please be noted that the system is NOT designed to reduce Total Dissolved Solids(TDS) removal and instead keeps essential minerals in your water. If you are interested in a filter that significantly reduces TDS, please consider our iSpring Reverse Osmosis (RO) systems RCC7 series or tankless RO500.
- [Peace-of-Mind Support] We offer tech and CS support via phone and email from Atlanta, GA. Contact our responsive and professional team for product selection to suit your water filtration needs and after-sale support to fully enjoy your user experience. Now, and years to come, we will be right here and ready to help.

We don't have a pre-drilled hole in our countertop. This system came up when we looked for a powerful under counter water filter- without a tank, easy to install, and no wastewater. Met all our expectations. Great system!

Our city water contains a lot of chlorine and we could not use this water for drinking. Got this system 4 months ago and it's been working AMAZINGLY! It is very easy to setup and the water takes great.

No more wasted plastic bottles and hauling around water bottles from the store. The water taste good and I don't have any complaints about the performance of the product.

I bought one for myself and another one for my parents. I installed both systems myself. I am not a plumber, just followed the directions and used common sense. Installation was not difficult at all. Water quality is great after purification. No odor, no cloudiness, no taste. 10 out of 10!

We have a stainless steel sink without many flat areas and we had no hole. Easy setup, great tasting water and high quality system.

The water will taste, well, tasteless, so it allows the food you are making to fully show its flavors without being masked by off putting flavors found in your tap water. Drinking RO water is the best choice for many families; but we want more- clean water for cooking! So we decided to get this undersink system instead. Filtered water for drinking, cooking, and washing all from our own kitchen faucet. Covenienct, time-saving, and economical!

Overall , I would recommended this to everyone looking for a new water filter but don't have enough undersink space or don't want to drill holes on countertop for a faucet. This product deserves 5 stars.
