After 15 hours of research evaluating 75 products, we picked Air Water Life Aqua Ionizer Deluxe 7.0 as our top choice.

You’ve probably heard some talk about the benefits of using an alkaline water filter at home. If not, we’ll give you a quick rundown.

Here's what we mean:

Alkaline water fans claim this hydrating beverage helps your body address everything from health issues to cosmetic concerns, including:

  • Digestion
  • Energy
  • Wrinkles
  • Blood pressure
  • Blood sugar
  • Loss of elasticity
  • Cancer symptoms

Are these alkaline water benefits actually legit?

Many health experts think so, and research shows alkaline water really does have some potential benefits.

For starters, alkaline water with an 8.8 pH level deactivates pepsin, the enzyme that triggers acid reflux symptoms and LPR problems.

Where can I get alkaline water?

You can buy alkaline water by the bottle from stores like Whole Foods or Fresh Thyme, or you can install an alkaline water filter in your home. If you decide to go with the latter, we can help.

Scroll through our list of the best alkaline water filters, whether you want a multifeature alkaline water machine or just need a basic alkaline water filter unit for your sink.

You might also enjoy our list of water pitchers with filters, although some of them aren’t alkaline. Happy hydrating!

This easy-to-install undersink reverse osmosis water filter system will only require 0.375 inches of space, allowing it to fit under almost any kitchen sink. It is considered one of the best water filtration systems due to its ability to minimize wasting water while also filtering it effectively.

The CleanWater4Less Countertop Water Filtration System is a stainless-steel compact unit that can fit almost any faucet, with the included adapters for its diverter valve.

PERFORMANCE

9.4 / 10

Why People Love it

  • Perfect for families due to its 75 gallons per day rating
  • 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.

Expert Ratings

Design

9.0 / 10

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

9.5 / 10

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.

Features

9.4 / 10

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

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

Value

9.3 / 10

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.

Makes tap water taste better, so you’re more likely to get the daily amount of water your body needs. Instant filtration process alkalizes water quickly.

Doesn’t filter out as many impurities as pricier models. No gauge or window to notify you when it’s time to change the filter.

Expert Ratings

Design

9.0 / 10

This is the slimmest alkaline water filter unit on our list, so it’s ideal for people with limited fridge space. Unfortunately, the lid seems to have issues remaining in place, so some reviewers have resorted to taping it closed.

The water pitcher comes with a 7-stage filter cartridge that works surprisingly well for its price.

Performance

9.5 / 10

The filter in this water pitcher is good but not great. However, it’s totally worth the cost.

The filter removes up to 90% of copper, lead, and other unwanted metals. That may sound like a lot, but keep in mind most other alkaline filters capture around 99% of heavy metals.

It also reduces odors and improves taste. Multiple reviewers say they love drinking tap water after running it through this pitcher.

Features

9.0 / 10

Filters for this water pitcher last up to 12 months based on how often you purify your water.

Value

9.5 / 10

Why People Love it

  • Follows rigid California safety guidelines
  • Water tastes pure
  • Affordable alternative to under-the-sink models

Includes all of the required hardware for a simple installation process that takes just 15 minutes or so. Removes heavy metals, chlorine, and odors.

An unsightly hose sits on the counter while the filtration system is connected.

Expert Ratings

Design

9.5 / 10

The filtration system that houses this alkaline filter is sleek and compact, but it has a bulky hose that is difficult to conceal. Some water drinkers report they’ve concealed the hose by attaching it underneath the faucet or building a small shelf around it.

This is a BPA-free countertop unit with a 5-stage filtration process. The replacement filter costs nearly as much as the unit itself, but it’s still cheaper than buying thousands of bottles of water each year.

Performance

9.5 / 10

Remove impurities like chlorine and heavy metals while reducing bacteria counts with this countertop water filtration system. Reviewers claim it eliminates the cloudiness found in some tap water, and it also gets rid of metallic odors.

This filter doesn’t just remove things, though - it also adds good stuff like potassium, calcium, and magnesium to your water.

Features

9.5 / 10

There aren’t really any special features on this USA-made countertop water filtration system, but it’s still a good option for folks interested in alkalizing their own water.

Expect to replace your water filter every 6 months, possibly sooner, depending on how much water you drink.

Value

9.5 / 10

Around $90 for the countertop unit with an included filter or $45 for just the filter.

Expert Ratings

DESIGN

9.5 / 10

9.5 / 10

This Air Water Life unit doesn’t disappoint when it comes to its features since it has plenty to offer. For starters, there are 7 different settings. You can use water alkalized by this unit for cooking, cleaning, drinking, or cosmetic use.

We also dig the self-cleaning interior because water filter units are notoriously difficult to clean.

The filter life span is about 12 months or 4,000 liters, whichever comes first. Replacement filters are around $40 to $45, which is reasonable.

VALUE

9.5 / 10

The cost of this water ionizer is $799.99, which is not cheap. But reviewers find it well worth the investment.
