Alkaline water has many health benefits, such as protection from oxidative damage, improved blood flow, and balanced pH. So, many Americans prefer it over other types of drinking water.
Yet, bottled alkaline water is expensive, and people need other long-term solutions. That’s when alkaline water filters enter the frame, whether in the form of water ionizers or water pitchers with alkaline filters.
For this guide, we tested various alkaline filtration devices in almost every category. In the end, we ascertained the best alkaline device in five different categories: water ionizers, water pitchers, countertop filtration units, under-the-sink reverse osmosis (RO) systems, and water bottles.

If you want a wide range of acidic and alkaline water options, the Tyent UCE-13 Plus Water Ionizer is the best device in its category. With its 1.7 to 12.5 pH range, 1.8 parts per million (ppm) hydrogen capacity, and -1,150 millivolts (mv) of oxidation-reduction potential (ORP), it’s a remarkable product.
Installed near a faucet, water ionizers operate by separating carbonate molecules from alkaline minerals and boosting the hydrogen levels in the water. As such, they’re able to produce highly acidic and alkaline (meaning, from both ends of the pH range) water with ease. In that respect, the 1.7-12.5 range of Tyent UCE-13 Plus has the widest range on the market.
Likewise, its -1,150mv ORP is nothing short of exemplary. With such ORP rates, Tyent UCE-13 Plus is the product that delivers the strongest antioxidant water among its competition.
Additionally, the device features a two-stage filtration process. In the first stage, an activated carbon block deals with aesthetic impurities such as taste, odor, color, and chlorine. The second stage consists of a 0.01-micron ceramic filter that targets pathogenic organisms like salmonella.
The colored LED display of Tyent UCE-13 Plus is also the most user-friendly feature. It allows you to:
- monitor the alkalinization process;
- pick one of its eight water pH options (three alkaline, three acidic, and one neutral pH modes, as well as a turbo hydrogen boost);
- and notifies you when the time to replace the filters comes (six to nine months, depending on the usage).
Plus, you’ll be happy to know that the manufacturer offers a lifetime warranty on its product.
However, all this comes at a price. Not only is Tyent UCE-13 Plus the most expensive item on our list, but at $4,795, it’s also one of the most expensive products in the whole water ionizing niche.

Water pitchers present a viable option for those who want access to alkaline water without breaking their budget, but the compromise is smaller pH ranges and ORP rates. The EHM Ultra II Premium Alkaline Water Pitcher is the absolute winner in its category with its alkaline capacity of up to 9.5 pH and ORP rate of -100mv to -200mv.
The product has a six-stage filtration process. The filter gauze, ion exchange resin, activated carbon, and polypropylene target impurities, including aesthetic ones, sediment, heavy metals, fluoride, and limescale. The alkaline mineral balls, negative potential balls, far infrared stones, tourmaline, and maifanite raise the pH of the water, reduce oxidation, and add healthy minerals such as calcium back into the water.
Besides its contaminant removal and alkalinization capacities, EHM Ultra II Premium entertains a 3.8-liter water capacity, roughly equalling a gallon. It also has a convenient shape, so it’ll be easy to fit it into your fridge if you like some cold alkaline water on a hot summer day.
Despite its many merits, the EHM isn’t tested or certified by third parties. Although user experience (our own and hundreds of others on online shopping sites) speaks for the efficiency of the product, it still would be nice for the product to have scientific backing.
Even worse, the pitcher doesn’t feature a filter change indicator, nor does the manufacturer provide info on the filter’s lifespan. Your options are to either call the manufacturer’s customer service or guess.
Similarly, the manufacturer doesn’t share info on the product’s warranty, so you’ll have to contact customer service for that, too.

The brand, Invigorated, is one of the leading manufacturers of alkaline water, whether for stainless steel pitchers, water bottles, or countertop dispensers. So, it’s no surprise that some of their products are the best in their categories.
The Invigorated Water Dispenser comes with a three-filter setup. Its three filters contain many different filtration media, including:
- An activated carbon coconut shell block that takes care of aesthetic impurities and gives water a pleasant taste,
- Two micro-nets that catch large particles like different types of sediment, clay, and rust,
- Zeolite, whose ion exchange properties trap heavy metal and fluoride molecules, toxins, and microbes
- A compound stone and ceramic ball blend that detoxifies, oxygenates, and alkalinizes the water while adding calcium, magnesium, and selenium into it
Unlike the EHM water pitcher, the Invigorated dispenser has been independently tested and certified. Some of its certifications are from highly prestigious organizations such as Société Générale de Surveillance and the Water Quality Association.
Besides its filter setup and scientific assurance, the Invigorated countertop device has an excellent water capacity. While its unfiltered water reservoir holds five liters, its filtered water reservoir stores seven liters.
Moreover, for a countertop unit with such great water capacity, it’s surprisingly compact. You won’t have any problem finding a place for it on your counter.
It also features long-lasting filters that produce 96 gallons of alkaline water without requiring replacement. For a family of four, that’s likely to last about three months.
As was the case with the EHM unit, the manufacturer doesn’t provide info on warranty for this product, so you’ll have to contact its customer service.
Finally, we couldn’t find info about its oxidation reduction potential.
APEC Essence Alkaline Mineral 6-Stage Reverse Osmosis System – The Best Alkaline Under-the-Sink RO System
- Filtration process: Activated carbon + sediment filter + RO membrane + calcite blend
- Water tank capacity: 4 gallons
- Filter lifespan: A year
- Filtration capacity: 75 gallons per day
- Warranty: One year
- Price: $234.95
- Calcite blend provides alkaline water
- RO membrane removes lots of hazardous pollutants
- One year of filter lifespan
- DIY-friendly installation
- Four-gallon water tank
- Made in USA
- Bulky for an under-the-sink unit
- Only one year of warranty
If you’re in the market for an excellent reverse osmosis system that doesn’t produce bland water, you need to look for alkaline RO systems. And alkaline RO systems don’t get any better than APEC Essence, with its state-of-the-art six-stage filtration process, highly efficient RO membrane, and pH-raising capacities.
Reverse osmosis systems are one of the most popular methods for removing dangerous contaminants from water. Still, they have two main drawbacks that damage their popularity: they remove healthy minerals from water and produce acidic water with low pH. Neither of these presents a problem with APEC Essence.
The six-stage process of the APEC RO first takes care of sediment and aesthetic impurities with a sediment filter and two activated carbon blocks. Then, the RO membrane blocks heavy metals and chemicals (lead, arsenic, cadmium, chromium, fluoride, VOCs), but also healthy minerals. Ultimately, this process renders water somewhat acidic due to its low mineral content.
But, a calcite blend rectifies that by introducing calcium carbonate into the end product. As a result, the water that comes out of your faucet is alkaline.
Another reason we favor the APEC unit is that it has more durable filters when compared to other under-the-sink systems. While industry-standard filters only last six months, you only need to replace the APEC ones once a year.
The product comes with fittings and connectors necessary for installation, too, easing the process and making it DIY-friendly.
In addition, APEC products are made entirely in the United States.
However, we should note that APEC Essence features a four-gallon filtered water tank. While it’s good to have some filtered alkaline water ready, it’s a bulky tank that some people might not have room for.
Also, the manufacturer offers only one year of limited warranty on its product. It’s a humble warranty option for a complex under-the-sink unit.
Invigorated pH Active Insulated Water Bottle – The Best Alkaline Water Bottle

- pH range: Up to 9 pH
- ORP: Not provided by the manufacturer
- Water capacity: 22oz or 32oz
- Filter lifespan: 26 gallons (2-3 months for a single person)
- Size: Length: 3.75″, Width: 3.75″, Height: 8″ (22oz), Length: 3.75″, Width: 3.75″, Height: 11″ (32oz)
- Warranty: Not provided by the manufacturer
- Price: $39
- Provides on-the-go alkaline water
- Removes heavy metals and fluoride
- Stainless steel body with a bamboo lid
- 26-gallon filtration capacity
- Comes in two size options
- Affordable
- Plastic straw
- No info on the warranty
You need an on-the-go alkaline water filter if you want to drink alkaline water everywhere. Thankfully, Invigorated thought of that and produced an insulated water bottle with an on-the-go water alkalizer pouch.
The Invigorated pH On-the-Go Alkaline Water Filter Pouch contains:
- Alkaline calcium balls to raise the pH of the water to 9 by adding calcium carbonate to it
- Oxidation-reduction potential balls to give water antioxidant and anti-inflammatory properties
- Maifan stones with high selenium, zinc, iron, and magnesium content to release minerals
- Far infrared stones to oxidate water
- Ceramic mineral balls to improve taste
- Zeolite to remove heavy metal and fluoride molecules
The main body of the Invigorated insulated water bottle is stainless steel with a bamboo lid, so you don’t have to worry about microplastics leaching into your drinking water.
For an on-the-go item, the Invigorated pouch has a remarkable capacity of 26 gallons. For a single person with average daily drinking water needs, that’s likely to last two to three months. But to stay on the safe side, we recommend replacing the pouch once every two months.
The bottle comes in two size options: 22oz and 32oz.
However, despite using stainless steel and bamboo in other parts, the straw of the Invigorated water bottle is plastic, albeit BPA-free. For us, it was a bit disappointing.
Lastly, the Invigorated bottle shares the warranty problem with the Invigorated dispenser. The manufacturer doesn’t provide any info.
Frequently Asked Questions
Below you’ll find the most commonly asked questions about alkaline water and filters and our answers.
Alkaline water has several proven health benefits:
External elements, namely air pollution and cigarette smoke, produce toxic free radicals in our bodies, resulting in oxidative damage. Alkaline water acts as an antioxidant against them, protecting our DNA.
It improves our blood flow. Especially for people involved in sports, it’s the best water to drink after exercise.
High levels of dairy, meat, and sugar consumption make the standard American diet acidic. Acidic diets lead to acid reflux in the long run. Alkaline water, especially if it’s calcium-rich, balances the pH of our blood and prevents or fights against acid reflux.
Some claim that alkaline water helps us maintain weight, improves the immune system, cleanses the colon, and aids healthy aging. Although we don’t deny these claims, further research is needed.
There are a couple of situations where an alkaline water filter may become a necessity:
If you’re on a high-acid diet, you need to balance it with consuming alkaline water
If you’re heavily involved in sports, alkaline water will help improve your blood flow and performance
If you already have a reverse osmosis unit installed in your household, an alkaline filter will add the minerals lost during the RO process back and neutralize the acidity of the RO water
Otherwise, it’s not a necessity. But considering the health benefits of alkaline water, it’s still a good idea.
Water ionizers are typically the strongest alkaline water producers on the market due to their wide pH ranges. Among them, Tyent UCE-13 Plus stands out with its ability to produce water that has a 12.5 pH.
Among non-ionizer units, though, the top spot belongs to the EHM Ultra II Alkaline Water Pitcher. This affordable water pitcher raises the alkalinity of water to 9.5 pH.
The answer to this question depends on what kind of water alkalizer you’re in the market for.
Water ionizers, like Tyent, usually cost an average of $4,000 to $5,000. So, they’re not exactly the most budget-friendly units you can purchase. Still, if you’re fond of alkaline water, they’re your best bet, and in the long run, they’ll prove more economical than buying bottled alkaline water.
Alkaline water pitchers cost between $20 to $100, depending on their reliability, water capacity, and filter lifespan. However, the frequency of their filter replacement adds up to costs in the long term.
Alkaline water dispensers typically cost $50 to $150. Filter replacement requirements are worth considering for water dispensers, too.
Alkaline RO units cost from $200 to more than $1,000, depending on the unit type.
Alkaline water bottles are similar to pitchers, with prices ranging between $20 to $100.
Conclusion
Alkaline water is associated with many health benefits and is among the healthiest water you can drink.
If you want the most alkaline water possible with the best product on the market, Tyent UCE-13 Plus is the obvious choice. It has a lifetime warranty, it produces up to 12.5 pH of alkaline water, and entertains staggering hydrogen boost and ORP numbers.
For those on a budget, a water pitcher might suffice, and the EHM water pitcher should be their go-to product with its ability to provide alkaline water up to 9.5 pH.
If you’re looking for a countertop water dispenser, the Invigorated water dispenser is compact and features a three-filter setup that removes many contaminants and raises the water’s alkalinity.
But, if you want an RO system but are reluctant because RO removes healthy minerals and produces acidic water, you should get the APEC Essence. This RO system features a calcite blend that raises the alkalinity of the water by adding calcium carbonate. Lastly, Invigorated has a state-of-the-art water bottle and alkalizer pouch if you want to drink alkaline water on the go.
