iSpring CU-A4 4-stage 0.1 micron Ultra-filtration Water Filter System
Top-rated 4-stage Ultra-filtration Water Filter
The iSpring #CU-A4 Ultrafiltration Water Filter System utilizes State-of-the-art UF Hollow Fiber Technology, the same technology in LifeStraw and Sawyer, which removes 7 log (99.99999%) of all bacteria and 6 log (99.9999%) of all protozoa. Its certified 0.1 micron (comparing to 0.2 micron in Watts UF3) absolute filter removes bacteria and protozoa at a higher rate than accepted EPA guidelines. Google "CDC Ultrafiltration" and find that Ultrafiltration is "very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia) and bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli) and moderate effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus)". Featuring a patent pending space-saving design and low pressure requirement makes it good for Home, Office, RV and Hotel, the CU-A4 can be installed in a matter of minutes.
4-Stage Sophisticated Filtration Removes Contaminants
- 1st Stage: 5 Micron Sediment filter that can effectively remove rust, sand, and solid impurities in water to protect delicate UF membrane. Cleaner Water Straight from the Tap and Refrigerator - 2nd Stage: State-of-the-art UF Hollow Fiber membrane uses standard home water pressure to push water through a semi-permeable membrane. Suspended particles and materials of high molecular weight, such as bacteria, are unable to pass through the 0.1 micron UF membrane, leaving you with only fresh clean water and dissolved minerals. - 3rd Stage: KDF media (or Kinetic Degradation Fluxion Media) with activated carbon. KDF itself is known to kill algae and fungi, control bacteria growth, and remove chlorine, pesticides, organic matter, rust, unpleasant taste and odour, hydrogen sulfide, iron, lead, nickel, chromium, cadmium, calcium, aluminium, mercury, arsenic, and other organic compounds. When used with carbon, KDF can extend carbon filter life for up to 8 times. It also adds a healthy dose of zinc ions to the filter water. - 4th Stage: Post Activated Carbon Filter adopting fine coconut shell activated carbon with ultra-micron aperture, this carbon filter absorbs residual chlorine, organics, humus, and odor.
Lightweight and Drain-free, can be installed anywhere. Enjoy Clean Water Wherever You Are
It is estimated that VOCs (volatile organic chemicals) are present in one-fifth of the nation's water supplies. These contaminants can enter ground water from a variety of sources, including herbicide and pesticide runoff, gasoline or oil spills, leaking underground fuel tanks, disinfection byproducts, septic system cleaners, and chemicals used in the dry cleaning industry. The CU-A4 keeps you safe from these and other VOCs with its three-stage filtration. Because it doesn't produce waste water and requires low water pressure, it can be installed anywhere, such as the back of refrigerator or in an Recreational Vehicle so you can enjoy cleaner, healthier drinking water wherever you are (Kitchen under-sink, Bar under-sink, Behind refrigerator, Bathroom under-sink, Office lunch room and waiting room, Restaurant, Clinical and medical patient room, Recreation Vehicle, Hotel room).
