Reusable water bottles usually are available in shapes which can be troublesome to wash with an ordinary kitchen scrubber, not to mention a sponge or your hand. Positive, you possibly can purchase a particular bottle brush , however a UV-powered self-sanitizing water bottle is a better path in the direction of attaining clear consuming water with out germs or micro organism. You may by no means have to really clear your reusable water bottle or fear about whether or not your water is filled with organic contaminants ever once more.

Not like filtered water bottles, which use a wide range of mechanisms to entice sediment and pathogens, self-cleaning water bottles use UV know-how to fully zap waterborne microbes and preserve them out of your drink, no matter your water supply.

The most important 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 do away with dust and sediment. So whereas the bottles can kill viruses, micro organism and different micro-organisms 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 could have clear water than conventional water dispensers or single-use plastic bottles , although.

Due to that, I made a decision to not check these self-cleaning water bottles outside. As an alternative, I used faucet water to search out out which self-cleaning bottles stood as much as their claims. I additionally did most of my water-drinking at house or within the workplace. So, which is the greatest self cleansing water bottle for clear consuming water? Listed below are my ideas, so you possibly can ditch your plastic water bottle and begin consuming from nearly any water supply with reckless abandon with your individual private water purification system!


The CrazyCap bottle has two water purification modes: regular mode and “loopy mode.” In keeping with CrazyCap, regular mode kills as much as 99.99% of contaminants and is appropriate for “low to medium contamination,” similar 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,” similar to from lakes and rivers. The traditional purification cycle takes 60 seconds and the loopy purification cycle takes two and a half minutes. 

The CrazyCap additionally has an autoclean perform, 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 record, which I appreciated. It matches into my automotive cup holders, in addition to the mesh cup holders on my fitness center bag and backpack. It’s kind of taller than the Larq and the Mahaton, so that you might need hassle becoming it within the high rack of your dishwasher. 

Personally, I believe the very best factor about CrazyCap is which you can purchase simply the cap, which in accordance with the web site matches on many various water bottles, possibly one thing you have already got. 

On a single cost, the CrazyCap will last as long as two months, however provided that you permit it to autoclean. Manually beginning the 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% 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.

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

The Larq bottle is product of vacuum-insulated chrome steel and retains your protected consuming water at a chilly temperature for as much as 24 hours. It is modern and aesthetically interesting — my solely criticism was that there isn’t any groove or curve to suit your hand. You possibly can all the time buy the limited-edition bottle sleeve to unravel that downside. 

A single cost on the Larq may give you as much as two full months of use, assuming you ship it by way of three to 4 cleansing cycles (in regular mode) per day. In case 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 bottle did not present any indicators of build-up — no bizarre smells, no crusty movies. 

Not like 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, similar to streams and different sources of groundwater. For that purpose, I would advocate solely utilizing the Mahaton bottle with indoor sources of consuming water except the corporate releases a brand new bottle with a further setting.   

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

One downfall? The Mahaton bottle holds simply 12 ounces of water, which I can drink in seconds. Most individuals would wish to refill this bottle as much as eight to 10 instances every day to get the gallons they need– that is quite a lot 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 will really feel burdened with charging the bottle. 

Which self-cleaning water bottle is greatest? 

Honestly, all three of those water bottles did a terrific job at maintaining themselves clear. After three days of consuming 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 the entire main waterborne pathogens; they’re all product of chrome steel (no low-cost plastic right here); they usually all have computerized cleansing cycles. On high of that, all three are tremendous straightforward to make use of they usually all have battery notifications so that they’ll by no means die with out warning. 

I had nearly no complaints about any of those self-cleaning bottles, and in the event you’re on the lookout for an aesthetically pleasing bottle that purifies your water, any of the three will get the job achieved. 

The one main distinction between the three? The Larq and the CrazyCap each have two modes, whereas the Mahaton solely has one. In case you plan on utilizing your self-cleaning water bottle with outside sources of water, you might wish to go for the Larq or the CrazyCap since they’ve overdrive modes that kill much more micro-organisms. 

How do self-cleaning water bottles work? 

Self-cleaning water bottles use UV-C mild to kill micro organism, viruses, protozoa and different micro-organisms 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 approach to preserve reusable water bottles clear with out the necessity for chemical substances or cleaning soap. Most self-cleaning water bottles, together with the three lined on this article, even have all of the options you’d search for in a standard reusable water bottle: They preserve steaming scorching water cold and warm water chilly (or room temperature water at room temperature), they usually’re sturdy. 

How did I check 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 residence’s kitchen sink (my most well-liked water supply). 

I often do not buy bottled water, and I haven’t got a faucet water filter, so I usually drink this water unaltered. I totally 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 must think about 5 necessary components when selecting a UV-powered water bottle like these: Purification, style, design, ease of use, capability and battery life. In case you determine to buy a self-cleaning water bottle, you will need one which kills as many microbes as doable, produces a superb style, is simple to carry and transport, and lasts for an honest time frame on one cost.
