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.

Since we live in an apartment, we couldn't drill a hole in the countertop for the spigot - so we just installed this us21b undersink water system, which doesn't require a seperate spigot. The system looks heavy duty. Installation was super easy and water flow is awesome! It's a nice purchase.

Exceptional product. The system itself is very well made everything is thick and sturdy I feel like I could drop it off my house and it would be okay.

I decided to give it a try after reading the facts and seeing that it had a lifetime support guarantee in US. Very satisfied with the water quality.

I am very pleased with this unit and recommend it to anyone that cares about what contaminants may be in their water. I live in a rental and didn't want to drill a hole in the waste water pipe because I would have to undo it when I move out, so I went with this direct connect system to ease my concerns for the water coming out from my kitchen faucet. It's been a couple of months and I can't be happier!

Maybe you enjoy paying 79 cents or more for a gallon of water that just might be plain tap water! The taste is great and cartridges are rarely replaced! I would recommend if you are looking for a water filtration system that puts out more volume (of water) than your refrigerator unit and better overall filtration.

Very nice product, I extremely recommend it. I was tired of needing to remember to pick up the water and being the only one in the house to replace the water jugs on the cooler! The water tastes great and has no odor.

Well built construction. Easy to change filters. We live in the country on well water. Great filtration producing quality water. I mounted this system below the kitchen on the basement wall. Lines are long enough to feed up through bottom of kitchen sink cabinet. I can change filters standing up and have a bucket on floor to catch any water. Best water filtration system I have had in the 33 years I have been here!
