Kangen Water Filter Review & Alternatives [2025]

The water that comes out of your tap travels through miles of pipes and treatment systems before making its way to your faucet. It’s a long journey—one where only 90 of the over 320 toxic substances found in drinking water are monitored. To stay safe from the health risks of contaminated water, filtering your H20 is a must.

While researching water filter options, you may have come across a few Kangen water filter reviews that piqued your interest. But everyone’s source water is different. Will a Kangen water filter really transform your water into the best water to drink?

This article explores everything you need to know about Kangen water filters to help you decide if they have what it takes to tackle the contaminants in your source water. Plus, we’ll cover the best alternative to Kangen water filters.

 

What is a Kangen Water Filter?

A Kangen water filter is the internal filter that comes with Kangen water ionizers, which are small appliances that calibrate the pH level of your tap water to make it more alkaline or acidic. The water can then be used in different ways, including for drinking, cooking, and cleaning.

Kangen vs. Enagic

Enagic is the manufacturer of Kangen water ionizers and the Kangen water filter, which is a basic 20-micron carbon filter. The company claims that Kangen water filters remove chlorine and reduce sediments up to 5 micrometers, along with “many traces of unwanted agents.” Yet, Enagic doesn’t specify what those unwanted agents are and a water filtration report isn’t available to check.

 

Things to Consider Before Buying a Kangen Water Filter

Before using a Kangen water filter to target the contaminants in your source water, there are several red flags about the product—and the company behind it—that you need to know about.

Numerous BBB Complaints

The Better Business Bureau (BBB) rates companies based on information they’re able to collect about them, including complaints submitted by the public.

Not only is Enagic not accredited by the BBB, but the company has been handed an F rating. Ratings represent the BBB’s opinion of how Enagic is likely to interact with its customers, with several of the company’s past customers leaving a review of Kangen water to warn others.

Unlike Enagic, Tyent is accredited with the BBB and has an A+ rating for excellent customer service and support.

Machines Operate Using Deadly Chemicals 

Kangen water machines are incapable of achieving a range of pH levels on their own due to a lack of power. As such, they require an “electrolysis enhancer” to work properly, which is a chemical cocktail that contains sodium hypochlorite—better known as bleach.

Worse, all water types produced by a Kangen water machine (Kangen drinking water, Strong Kangen water, and Strong Acid water) involve using the same water cell, yet Kangen doesn’t provide clear guidance on how to handle the electrolysis enhancer properly.

Some models of Kangen Enagic water machine also have a chemical injection port for adding glycerophosphoric acid calcium to boost alkalinity, too much of which can cause nausea and constipation, and encourage kidney stone formation. Enagic claims the additive is only necessary if your tap water has a pH below 6. This is misleading, however, since the U.S. Environmental Protection Agency mandates that tap water have a minimum pH of 6.5.

Thanks to Tyent’s cutting-edge SMPS Plus power supply, Tyent water ionizers can produce strong alkaline and acidic water without using chemicals.

No Evidence to Support Antioxidant Claims

Enagic claims that Kangen alkaline water is rich in molecular hydrogen—a liquid antioxidant that lowers the risk of future health problems by helping to neutralize free radicals in the body. Only, Enagic offers no evidence to support these claims and the company’s product specifications contradicts them.

The lower your water’s oxidation reduction potential (ORP) reading, the more potent its antioxidant properties. Enagic’s most powerful Kangen water machine only has an ORP of -800. For context, Tyent water ionizers produce alkaline water with a negative ORP of up to -1,250 (and Tyent holds many certifications to prove their water ionization systems actually deliver).

Lack of Machine Power to Support Large Plates

One of the selling points that Enagic prominently highlights about the Kangen water machine is its large plates—the larger the plates, the better the results. However, they lack the power required for these large plates, so is Kangen water really hydrogen water?

Kangen water machines feature a linear power supply with heavy transformers, which are inefficient, prone to overheating, and don’t allow for voltage adjustability. This is why there are only five water settings to choose from (that can’t be adjusted to your source water) and chemicals are needed to achieve a wider range of pH levels.

Tyent’s innovative SMPS Plus power supply provides 55 adjustable power settings, so you can pour the perfect glass of hydrogen-rich alkaline water based on your unique source water.

Expensive Machines, Short Warranty

Kangen water ionizer machines are the most expensive on the market, ranging from $4,000 to $6,000 USD, yet come with the shortest warranties—a 3 or 5-year limited warranty, depending on the model, and riddled with stipulations. If you want an extended warranty, it costs an additional $600 and only gives you another three years of coverage.

Enagic’s trial period and return policy are just as stingy. For starters, a full refund (minus shipping) is only be granted if the machine is unused and returned within 7 days of receipt. If you miss the 7-day window but send it back within 30 days of receipt, you’re charged a $100 restocking fee.

But you don’t buy a product just to send it back unopened; you buy products to try them. Yet, the company still expects you to send the machine back within the 7-day window. That means you have only three days to test it out before you have to send it back. Missing the 7-day window means being charged a cancellation fee and potentially losing up to $1,100 plus shipping.

Tyent, on the other hand, offers a generous 75-day trial and return period to make sure you’re fully satisfied with your purchase, along with a no-quibble lifetime warranty.

More About Kangen Water Filters

After browsing Kangen water filter reviews, you might still have unanswered questions. Read on for answers to frequently asked questions about Kangen water filters.

Are Kangen water filters worth it?

No, Kangen water filters aren’t worth it. Water ionizer filters—like the cutting-edge dual Dialapure filtration system that comes with Tyent water ionizers—should address filtration needs specific to your source water. Kangen machines only come with a single standard filter with no adjustability, making them inadequate for dealing with many of the toxins found in tap water.

What does Kangen water filter out?

According to Enagic, the Kangen water filter “filters chlorine, unpleasant taste and odor, and reduces sediments up to 5 micrometers to produce Clean Water.” There’s no mention of whether the Kangen water filter removes lead or other dangerous toxins and Enagic refuses to share a water filtration report. You can see here how many contaminants Tyent filters remove.

What are the disadvantages of Kangen water?

There are many disadvantages of Kangen water, but the most concerning is that Kangen machines are unable to produce high and low pH levels without chemical enhancements. Worse, the chemicals used are sodium chloride and sodium hypochlorite—the main ingredients in your bleach bottle.

Another red flag is the sole generic Kangen water filter the machines come with. Enagic is eerily vague about the number of contaminants it removes and a water filtration report isn’t available.

What is the best alternative to Kangen water?

The best Kangen water alternative is Tyent water, hands down. Tyent water ionizers outshine Kangen models in every way. They have the largest plate surface area in the industry, the best filtration system, are fully customizable to your source water, and don’t require chemical enhancements to produce high and low pH levels, among many other next-level features.

 

The Bottom Line: Kangen Water Filters

Between the Kangen water filter being generic with no adjustability, the vague explainer Enagic provides regarding its effectiveness, and the lack of a water filtration report, it’s unlikely that Kangen machines provide the level of water filtration you’re after (and deserve).

Tyent water ionizers are superior to Kangen models in all categories, especially filtration. Tyent’s dual Dialapure filtration system is of the same caliber used in kidney dialysis machines. The 0.01micron filtration level (compare that to Kangen’s 20-micron) removes over 200 dangerous contaminants from your tap water, including 100% of lead. Tyent’s water filtration report speaks for itself.

Add to that Tyent’s top-of-the-line plates, chemical-free electrolysis capabilities, and fully adjustable power settings, and you’ll always have access to clean, pure, drinking water that’s antioxidant-packed—and customized exactly to your liking.

Not only does Tyent offer customers a no-muss no-fuss lifetime warranty, but a generous 75-day trial period to make sure you’re 100% satisfied with your purchase.
