Staying hydrated all through the day isn’t any straightforward activity. Whether or not you have simply completed your exercise on the gymnasium, are taking a brief hike and even finishing each day duties on the workplace — you must be sure you’re ingesting sufficient water. And the key to a wholesome and hydrated life is a good reusable water bottle that you would be able to refill often. Reusable water bottles are additionally key to decreasing your influence on the surroundings. 

The draw back is you will should be sure you hold it clear, in any other case it might probably develop into a breeding floor for micro organism. Throwing it within the dishwasher from time to time might help, however the easiest way to make sure the water inside is at all times contemporary and secure is with a self-cleaning water bottle. Self-cleaning water bottles guarantee that your water is freed from contaminants and make sure that you will by no means have to scrub your water bottle by hand once more. 

Self-cleaning water bottles use UV know-how to zap waterborne microbes and hold them out of your drink, whatever the water supply. That is not like filtered water bottles, which use quite a lot of mechanisms to lure pathogens and sediment.

Left to proper: The CrazyCap, Mahaton and Larq bottles all sanitize themselves with UV-C mild.

The largest distinction between water bottles that present filtration and self-cleaning water bottles is that the UV know-how utilized in self-cleaning bottles does not eliminate dust and sediment. So whereas the bottles can kill viruses, micro organism and different microorganisms that may make you sick, they will not filter out heavy metals or different particulates like an precise purification system may. Nonetheless higher at guaranteeing you’ve clear water than conventional water dispensers or single-use plastic bottles, although.

Due to that, I made a decision to not take a look at these self-cleaning water bottles outdoor. As a substitute, I used faucet water to seek out out which self-cleaning bottles stood as much as their claims. I additionally did most of my water ingesting at house or within the workplace. So which is the very best self-cleaning water bottle? Listed below are my ideas: Ditch your plastic water bottle and begin ingesting from virtually any water supply with reckless abandon utilizing your individual private water purification system!


The CrazyCap bottle has two water purification modes: regular mode and “loopy mode.” In response to CrazyCap, regular mode kills as much as 99.99% of contaminants and is appropriate for “low to medium contamination,” comparable to from public water fountains and faucet taps. Loopy mode, then again, kills as much as 99.9996% of contaminants and is appropriate for “medium to excessive contamination,” comparable to from lakes and rivers. The conventional purification cycle takes 60 seconds and the loopy purification cycle takes two and a half minutes. 

The CrazyCap additionally has an autoclean operate, which activates six instances per day for 20 seconds. CrazyCap says this periodical publicity to UV-C mild prevents microbial development and odor, and it appears to work: After three days of use, I did not discover any smells or movies contained in the bottle. Moreover, purified water from the CrazyCap bottle tasted considerably higher than water from the faucet faucet.

The CrazyCap bottle is extra slender than the others on this checklist, which I favored. It suits into my automobile cup holders, in addition to the mesh cup holders on my gymnasium bag and backpack. It’s kind of taller than the Larq and the Mahaton, so that you might need bother becoming it within the high rack of your dishwasher. 

Personally, I believe the very best factor about CrazyCap is that you would be able to purchase simply the cap, which based on the web site suits on many various water bottles, perhaps one thing you have already got. 

On a single filtered water bottle cost, the CrazyCap will last as long as two months, however provided that you permit it to autoclean. Manually beginning the self-cleaning water bottle purification cycle impacts that cost time, although CrazyCap does not specify by how a lot.


The Larq bottle additionally has two purification modes: regular and journey. Regular mode purifies as much as 99.99% of pathogens in 60 seconds, and journey mode purifies as much as 99.9999% of water in three minutes. It does not look like a lot of a distinction, however that 0.0099% water filtration could make or break water that comes from a stream or different pure supply. 

You may activate the UV-C purification mild everytime you need by urgent the button on the highest of the bottle, however Larq additionally involves life each two hours for a 10-second cleansing cycle. I did not discover any funky smells or movies on the within of the Larq bottle after three days of fixed use of the self-cleaning bottle.

Larq was the one one of many three bottles that did not style considerably higher than my water, nonetheless. It tasted barely cleaner, however I most likely could not inform the distinction if somebody blind taste-tested me. 

The Larq bottle is made from vacuum-insulated stainless-steel and retains your secure ingesting water at a chilly temperature for as much as 24 hours. It is modern and aesthetically interesting — my solely criticism was that there is no groove or curve to suit your hand. You can at all times buy the useful journey sleeve to resolve that downside. 

A single cost on the Larq may give you as much as two full months of use, assuming you ship it by three to 4 cleansing cycles (in regular mode) per day. When you use journey mode, the cost will last as long as 12 days.

The Mahaton self-cleaning water bottle (out there for preorder for $44) options one purification cycle that eliminates as much as 99.99% of waterborne pathogens. After three days of near-constant use, the self-cleaning water bottle did not present any indicators of build-up — no bizarre smells, no crusty movies. 

In contrast to the CrazyCap and the Larq, the Mahaton bottle does not have a further purification setting for our bodies of water that may include extra contaminants, comparable to streams and different sources of groundwater. For that purpose, I would advocate solely utilizing the Mahaton bottle with indoor sources of ingesting water until the corporate releases a brand new bottle with a further pure water self-cleaning bottle setting.

The Mahaton bottle contains a modern form with a pleasant double taper that makes it straightforward to carry. It is made from double-wall stainless-steel, so it is sturdy and it will hold your water chilly for hours. It is also small, so you shouldn’t have any points becoming the Mahaton bottle into holders or luggage. 

One downfall? The Mahaton bottle holds simply 12 ounces of water, which I can drink in seconds. Most individuals would wish to refill this water filtration bottle as much as eight to 10 instances every day to get the gallons they want — that is plenty of interruptions to your day.

The Mahaton bottle can last as long as three weeks on a full cost, assuming you run the purification cycle as much as 4 instances per day. That is barely lower than the CrazyCap and the Larq, however not such a brief battery life that you’re going to really feel burdened with charging the bottle. 

Which self-cleaning water bottle is finest? 

In truth, all three of those water bottles did a fantastic job at retaining themselves clear. After three days of ingesting and fixed refills and no hand-washing, none of those bottles smelled musty or had any type of movie on the within, two issues my regular metal bottle usually produces.

The Larq, CrazyCap and Mahaton all use UV-C mild to zap all the main waterborne pathogens; they’re all stainless-steel water bottle choices (no low-cost plastic water bottles right here), and all these finest self-cleaning bottle decisions have computerized cleansing cycles. On high of that, all three are straightforward to make use of they usually all have battery notifications so that they’ll by no means die with out warning. 

I had just about no complaints about any of those self-cleaning bottles, and should you’re searching for an aesthetically pleasing bottle that purifies your water, any of the three will get the job performed. 

The one main distinction between the three? The Larq and the CrazyCap each have two modes, whereas the Mahaton solely has one. When you plan on utilizing your self-cleaning water bottle with out of doors sources of water, you could need to go for the Larq or the CrazyCap since they’ve overdrive modes that kill much more microorganisms. 

How do self-cleaning water bottles work? 

Self-cleaning water bottles use UV-C mild
to kill micro organism
, viruses, protozoa and different microorganisms by destroying their DNA. The UV mild sterilizes each the water within the bottle and the inside floor of the bottle. 

UV-C mild serves as a handy, largely hands-off solution to hold reusable water bottles clear with out the necessity for chemical substances or cleaning soap. Most self-cleaning water bottles, together with the three coated on this article, even have all of the options you’d search for in a traditional reusable water bottle: They hold steaming sizzling water cold and hot water chilly (or room temperature water at room temperature), they usually’re sturdy. 

How did I take a look at these self-cleaning water bottles? 

I examined three UV-powered self-sanitizing water bottles — the Larq bottle, the CrazyCap bottle and the Mahaton bottle (which is on Kickstarter, however is totally funded and already transport merchandise) — utilizing the faucet water from my condo’s kitchen sink (my most well-liked water supply). 

I normally do not buy bottled water, and I haven’t got a faucet water filter, so I usually drink this water unaltered. I completely cleaned every bottle and charged them in a single day to make sure they have been prepared for testing. Then, I used every bottle for 3 days rather than my regular reusable bottle. 

What to search for in a self-cleaning water bottle

You need to take into account six vital components when selecting a UV-powered water bottle like these: Purification, style, design, ease of use, capability and battery life. When you resolve to buy a self-cleaning water bottle, you will need one which kills as many microbes as doable, produces a great style, is straightforward to carry and transport, and lasts for an honest time period on one cost. 

1. Purification: What does the bottle promise to eliminate, and at what proportion? Additionally, how lengthy does it take for the bottle to purify the water? Is there an autoclean operate? I additionally thought-about how the bottle smelled and regarded on the within after three days of use. 

2. Style: How does the water style after going by the purification cycle, in comparison with my ingesting water? 

3. Design: What’s the bottle made from and the way handy and simple is it to hold round? Does it hold water chilly?

4. Ease of use: How straightforward is it to arrange the bottle for first use, clear it and retailer it? 

5. Capability: How a lot water does the bottle maintain? Will you be refilling it always, or will the pure water final you some time?

6. Battery life: How lengthy does the bottle final (and what number of cleansing cycles can it full) on a full cost?
