  • Easy installation
  • Purifies and alkalizes tap water

Remineralization filter adds back healthy minerals that are often lost during water filtration. Resilient multilayer membrane effectively handles frequent use and high filtration volumes.

There aren’t many cons, but the price and large size bother some consumers.

Details

Design: This alkaline water filter system weighs in at 20 pounds, so it’s pretty heavy compared to other systems. It’s also about 1.5 feet tall, but it’s slightly larger than the Air Water Life Aqua Ionizer Deluxe 9.0.

Its high capacity is one reason we chose this iSpring unit as the best alkaline water filter system. Unlike the numerous units geared toward individual users, this 6-stage filtration system boasts a rating of 75 gallons per day. That’s probably enough for your entire family to drink, clean, and cook all day long.

Most owners say installation is simple, but they warn that it takes a while. The company offers phone support for consumers who need assistance.

Performance: If you hate contaminants in your water, this iSpring unit is your dream machine. It removes more than 1,000 contaminants at a rate of 99%, and it eliminates up to 98% of lead.

Like most filtration units, it gets rid of heavy metals. However, it also helps remove hormones, arsenic, asbestos, viruses, and other disgusting things that lurk in your water. The filter is housed in a see-through piece, so you can easily see when it’s replacement time.

Special Features: The iSpring unit has no special features, but reviewers are okay with that. It’s a reliable unit that does what it promises.

Life Span: Each filter lasts for 6 to 12 months, and the membrane lasts for 2 to 3 years.

Price: Expect to pay around $210 for this iSpring unit, plus $65 for a set of replacement filters once or twice a year. That’s still cheaper than buying bottled water for your entire family on a regular basis.
