Here at the Strategist, we like to think of ourselves as crazy (in the good way) about the stuff we buy (like pillows), but as much as we’d like to, we can’t try everything. Which is why we have People’s Choice, in which we find the best-reviewed (that’s four-to-five-star reviews and lots of ’em) products and single out the most convincing. And while we’ve talked about the best water filters before, including one Japanese charcoal filter and a shower filter, here we’ve gone deep into the best alkaline water machines, filters, and pitchers on Amazon, according to the people. (Note that reviews have been edited for length and clarity.)

Best alkaline water pitcher

pH Restore Alkaline Water Pitcher

“I have been using this pitcher for almost a year. I was buying bottled alkaline water and hated the fact that I was still adding to the problem of all the plastic bottles in the landfill. I had investigated an alkaline-slash-ionizer machine but they were too costly, so I thought I would give this pitcher a try. I wasn’t really expecting much because of the price, but when I test the water with my litmus papers and drops, it comes back as 9 or 9.2, even after the filters are about one-and-a-half months old, so I was sold. I am on my fourth filter, and they all have performed awesomely — just don’t forget to rinse them well before use.”

Ehm Ultra Premium Alkaline Water Pitcher

“I am a physician, and have researched the value of alkaline water extensively. However, most alkaline water is only available in plastic one-liter bottles, which makes them expensive to consume in quantity. When I learned of the Ehm Ultra Premium Alkaline Water Pitcher, at such a reasonable price, I ordered it immediately. Now, my town’s water supply is actually very good in it’s purity and taste — or so I thought. The pitcher was easy to set up with clear directions. Right from the start I could easily taste the difference. The taste reminded me of the best of the store-bought plastic bottled alkaline water, and directly comparing my tap water to this filtered water revealed the obvious superiority of using this product … It is well-made, durable, and the filtering process is quite rapid.”

iSpring 6-Stage Superb Taste 75 GPD High Capacity Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization

“I’ve had this filter system installed for four years now and won’t be without it. Our water has a high level of chlorine in it, and this system takes all of it out. I know this because when I run tap water in the sink and use the pool test chemical to test it, the water turns bright yellow, which indicates chlorine. When I run water from my [reverse osmosis] faucet, it runs clear and does not turn bright yellow. I also like the fact that this system has an alkaline filter to add some vital minerals back in, since it strips so much out during the filter process. I was also able to install this myself with the help of the videos I found on their website, so if you are a do-it-yourself type of person, you should be able to handle this with no problems. I calculated the cost to run this from how much I pay for filters each year, and it works out to about 27 cents per day, which is much cheaper than bottled water.”

Apec Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System

“Water is delicious with minerals put back in through the alkaline [filter]. Our water is bad in Vegas, can’t drink or cook with it. This is our fourth RO unit over the years. Typically, RO water tastes flat. So glad we got this unit with minerals added back in. We think it tastes like Fiji water. There’s a definite crispness that’s so refreshing. Super happy we bought this one.”

Express Water Alkaline Reverse Osmosis Water Filtration System

“I bought this water system for the alkalinity. After installing it, I did an alkalinity test, and it turns out that this product makes alkaline water with a pH of 10, if not better. Also, I used a digital PPM meter, and it showed a 0.22 as far as contaminants in the water. I compared this to an alkaline machine, which are worth about $3,000 plus, and the results I found for the price of this filtering system is far better and cheaper than an alkalizing machine. I am definitely looking into buying a secondary system for my house, and I would definitely recommend one of these filtration systems. Excellent product.”

Best alkaline water machine under $1,000

Air Water Life Aqua Ionizer Deluxe 7.0

“I have had my machine for over a year now and love it. I do the pH test frequently and have consistently found a 9.5. The price point is reasonable, which is completely not the case for the other ionizers in the industry. I have had to call customer service on a couple of issues and have found them to be exceptional, going above and beyond in dealing with questions … The carbon replacement filters are also excellent on price point and usage duration. For overall health, I cannot imagine a better investment as the many advantages of using high-alkaline water.”

Best alkaline water machine

Bawell Platinum Alkaline Water Ionizer Machine

“I had wanted a water ionizer for a long time, but didn’t want to spend the high price asked by those selling the leading well-known machine. After a lot of research, I bought this one because it had similar specs to the top-of-the-line competitor’s model I had tried and liked, but this Bawell was a much better deal at less than half the price. It has a lifetime warranty and not only came with extra filters but also a complete set of pre-stage filters, which usually cost extra. Our local tap water has a noticeable smell of chlorine, and this machine removes it all. I no longer buy bottled water, as I can use my own four choices of alkaline water or purified water for drinking now. I use the acid water for cleaning fruits and vegetables and other cleaning. Everyone that comes to my house loves my machine and the water, and several friends are now considering purchasing one, too.”
