iSpring RCC7AK, NSF Certified 75 GPD, 6-Stage Reverse Osmosis System, pH+ Alkaline Remineralization RO Water Filter System Under Sink, Superb Taste Drinking Water Filter

  • Certified to NSF/ANSI 58, 6-Stage Alkaline Remineralization Layered Filtration - Exclusively designed to restore the natural alkalinity and mineral balance of water; this reliable and ultra-safe Reverse Osmosis (RO) water filtration system converts your water into clean, pure and healthy drinking water by removing up to 99% of over 1,000 harmful contaminants like chlorine, fluoride, lead (removes up to 98%), arsenic, asbestos, calcium, sodium and more.
  • GREAT-TASTING MINERAL WATER - A standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below because the RO membrane removes not only harmful pollutants but also a few helpful minerals. The iSpring RCC7AK Reverse Osmosis water filter includes an additional 6th stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives your water a more natural taste than regular 5 stage RO water filter.
  • LOW MAINTENANCE - Transparent 1st stage housing for easy visual inspection. Three extra long life pre-filters to remove large contaminants and protect RO membrane. Ultra fine (RO) filter to remove contaminants down to 0. 0001 microns; fine GAC filter to provide final polishing to the purified water and (AK) filter to finally restore just the right proportion of healthy minerals and a natural alkaline balance. The end result is great-tasting bottled-water quality.
  • EASY TO INSTALL & NO LEAKS - The water purifier is designed for do-it-yourself installation and all necessary parts for installation are included. Backed by clear installation manual, instructional videos, and access to life-time technical support. The entire alkaline water filter fits nicely under a kitchen sink. For leak-free installation, simply push tubing ½ inch deep into quick-fitting connectors and lock; no threading pipes needed.
  • 100% SATISFIED CUSTOMERS - RCC7AK from America’s favorite brand of under sink water filter is the highly rated reverse osmosis systems.

Frizzlife Reverse Osmosis Water Filtration System - Alkaline & Remineralization, Superb Taste, Tankless, 500 GPD Fast Flow RO Filter, 1.5:1 Pure to Drain, Reduces TDS, Brushed Nickel Faucet, PX500-A

  • 【Superior filtration performance】Frizzlife PX500-A under sink tankless reverse osmosis water filtration system has a RO membrane (ASR312-500G) with precision at 0.0001 micron, which eliminates more than 1000+ kinds of contaminants (99.99%) from water including fluoride, chlorine, chloramine, TDS, limescale and lead&other heavy metals. The pre-filter (ASR311) greatly prolongs the service life of the RO membrane while the post alkaline filter(ASR313-A) remineralizes the pure water.
  • 【Tankless design】With a high capacity of 500 Gallons per day, Frizzlife PX500-A RO water filter system abandons the traditional water tank. It takes up less space under the counter and swipes out the secondary pollution caused by the unventilated tank. The direct water flow reaches up to 0.4 GPM@ 60psi. The system could also be hooked up to your refrigerator by using IMC-1 ice maker connection kit, providing you with crystal and healthy ice cubes.
  • 【Easy DIY installation】Comes with filters loaded, Frizzlife RO water purification system is an integrated RO unit without a tank nor massive connection points. Fewer leakage concerns! It can be installed all by yourself in a breeze following a step-by-step installation video and comprehensive instructional user manual. Everything needed for installation is included in the package including a brush nickel faucet set! Save money from plumber hiring!
  • 【Filter life reminder & quick change】A filter life monitor is embedded in the operation panel. Blue light stands for good while red represents for low life, and it will beep when a change is needed. The replacement of Frizzlife RO water filtration system takes only 2 sec by a SINGEL TWIST. Change the 1st per 6 months, the 3rd stages per 1 year, and the 2nd RO membrane per two years. Frizzlife mini water tank is also now available to boost up water pressure for better ice cubes.
  • 【Remineralization & super low drain ratio】One more step beyond pure water towards healthy, the 3rd stage of the RO system could alkalize pure water by adding back essential minerals and raise the pH to more than 7.5. Moreover, the system produces much less waste water as a reverse osmosis system. By generating 1.5 cups of pure water, only 1 cup of waste water would be drained, saving your bill and water.
