If you’re at all interested in health and wellness, you’ve no doubt heard the excitement surrounding alkaline water and its benefits. You might even be excited about jumping on this health craze! But there’s a problem: there are a ton of products out there! Have no fear. This article will filter out the gunk (see what we did there?) and give you the top 11 alkaline water filters.

Why You Need an Alkaline Water Filter

Alkaline water has a higher pH level than normal water. The theory is that alkaline water will neutralize acid in your bloodstream and provide a myriad of health benefits. Studies are underway to validate claims that Alkaline water prevents cancer and heart disease, among other ailments.

If you’re looking to experiment with alkaline water, or if you suffer from high blood pressure, high cholesterol, acid reflux, or diabetes, buying an at-home water filter or ionizer is your best bet. It’s far cheaper than buying bottled alkaline water, it’s more convenient, and it ensures your source is as clean as possible. 

Cheaper

Here’s the naked truth: companies love jacking up the price of health-related items — especially if there’s a particularly high demand. Alkaline water is big right now. That means bottled water companies are going to skyrocket their shelf prices because they know health-conscious people are always prepared to pay more for better, cleaner, healthier goods. Alkaline water sells for outrageous prices. Some retailers are selling single bottlesfor around $10 USD, while six-packs can range from $20-$40! Yikes!

If you’re drinking your water regularly – and you should be! – then you can easily spend a small fortune on your water. It might seem more expensive in front-end cost, but the value over time means a home alkaline filter is way more bang for your buck. 

Convenient

We lead busy lives! Especially those of us who are trying to stay fit. Between work, friend and family obligations, fitness upkeep, and hobbies, it can be a challenge to get everything done each day. Why add one more chore to your list by constantly having to refill your purified water via store-bought packs or bottles? This is in line with being cheaper, too. You’ll have to make time to go to the store frequently and buy more water, which can translate into higher gas or public transportation costs. That’s no fun — especially if the goal is to find the best, easiest solution!

Cleaner

There is a ton of research out there on the dangers of drinking bottled water. Whether it’s alkaline water or not, water bought in bottles can come with a whole host of problems! There’s always the potential for foreign chemicals to enter your water in the factory and at the collection site. Even worse: water in plastic bottles can become contaminated by plastic molecules and other nasty particulates just from sitting in a bottle. And, yes, some brands are definitely better than others.

Plus, plastic bottles aren’t very sustainable. Let’s not add more to the plastic garbage islands forming in our beautiful oceans, yeah? Buying a home water filter solves this problem immediately.

Balance Your Water with an Alkaline Water Filter

Types of Alkaline Water Filters

There can be a lot of confusion over alkaline filters. This is because lots of people use alkaline water filters and alkaline water ionizers as interchangeable terms. But they’re different. We’ll avoid all the technical mumbo-jumbo and make it easy: ionizers use electrolysis (zaps of electricity) to change the pH balance in regular water, making it alkaline water. Alkaline water filters run drinking water through mineral filters (and sometimes magnets). Filters usually don’t use electricity.

Aside from those two major categories, the placement of filters and ionizers can vary.

Whole Home Filters/Ionizers

Whole-home filters, or “whole-house filters,” are designed to filter or ionize the water coming into your entire home. They hook up to your house’s plumbing, between the water intake and the pipes branching to the different places in your home. These are expensive and big. They also require professional and experienced installation. 

* Note: There are almost no whole-home alkaline ionizers. Whole-home systems are almost always filters, but some do come with alkalizing components.

Under-the-Counter Filters/Ionizers

Under-the-counter (or UTC) filters/ionizers are much smaller than whole-home units. They only filter the water at a local source (i.e.: whatever sink to which they’re attached). These units are installed in a single sink’s plumbing and filter only the water at the sink. They’re much cheaper than whole-home units and require significantly less expertise, but they obviously don’t filter or ionize as much water. There are a few Reverse Osmosis filters that have alkaline components as well.

Countertop Filters/Ionizers

Most (but not all) countertop filters/ionizers attach directly to a sink’s tap. There are some stand-alone units that can sit on the counter, but those A. aren’t very convenient; B. take up a ton of space; and C. don’t ionizer or filter very much water. If you’re looking for a countertop filter – which requires basically no plumbing experience or professional installation – then you should consider a unit that plugs right into the tap.

Pitchers, Bottles, Etc.

There are smaller ionizers and filters designed for very limited use, usually found in the shape of stand-alone (“drop-in”) filters or bottles. These units are much cheaper than the units that plug directly into plumbing, but they also have a smaller range of use. They’re also not very convenient. Still, these kinds of filters can be great for those trying to filter water on a budget, campers, those on the go, or people in a pinch!


Top 11 Best Alkaline Water Filters

Below is a list of our top 11 choices for alkaline filters. The list is not in any specific order. We’re showcasing a variety of products for you to research, so you’ll see all sorts of ionizers and purifiers. But this is not an exhaustive list of products. As with any health product or new buy, make sure you’re doing your own thorough research!

Aqua Ionizer Deluxe 9.0 Aqua-Ionizer Pro Alkaline Water Ionizer Machine

This bad-boy is the king of alkaline water ionizers. Perhaps the most impressive quality of this unit is its ability to be installed either as an under-the-counter or countertop unit. (If you want to install it under-the-counter, you’ll need to order a special installation kit from the manufacturer.) It’s a hefty machine with seven different settings, ensuring you get exactly the pH balance you’re looking for. It’s also equipped with a built-in charcoal filter. There’s barely anything bad to say about this unit other than price. In this case, you really do get what you pay for. Other than that, just be careful about maintaining the charcoal filter. If you don’t change it for a while, you can expect your water to have a bit of a charcoal aftertaste.

iSpring RCC7AK 6-Stage High Capacity Under Sink System with Alkaline Remineralization

This unit is considerably cheaper than the first entry on the list. It’s installed as an under-the-sink system with three chamber filters. That means it has an excellent level of filtration, plus it’s equipped with a reverse osmosis and alkaline remineralization filter. You will definitely get clean water out of this system. Unfortunately, because of its size, you can also expect it to take up quite a bit of space under the sink. Make sure you’re doing your proper measurements if you’re looking to buy this beast.

  • High Capacity Reverse Osmosis water filtration for safer, healthier water.

  • Experience clean, safe, good-tasting water every time you turn on the faucet. Enjoy crystal clear ice cubes, fresher tea and coffee, better tasting foods, healthier baby formula - even better than most bottled water.
  • The RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below. The iSpring RCC7AK includes an additional sixth stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives the water a more natural taste than regular 5 stage RO water.

Express Water Alkaline Reverse Osmosis Filtration System

It can be hard to find an affordable system that also does a fine job. This Express Water reverse osmosis system is one of those rarities. This under-the-sink behemoth is pleasantly color-coded, taking all the guesswork out of installation and maintenance. It’s specifically designed for people with no plumbing experience at all! There are only two drawbacks to this system. First, it’s big, which means you need to ensure you have the space necessary to install it. Second, the pressure gauge can sometimes tend to malfunction (read: lie), so make sure you keep an eye on it. The manufacturer supplies wonderful customer service and will help you replace the gauge in the event of a malfunction.
