Reusable water bottles have become popular, thanks to their environmental advantage. Aside from being a sustainable alternative to plastic bottles, they save you money in the long run. However, these eco-friendly drinkware require regular cleaning. Otherwise, they can become a breeding ground for germs and bacteria.
If you’re one to forget to wash your drinkware, consider self-cleaning water bottles. As their name suggests, these bottles can kill germs and bacteria. Most use UV light technology built into their caps. Others rely on low-tech but reliable water filters. Regardless of the type you get, these self-sanitizing drinkware should give you peace of mind. Below, we share the best self-cleaning water bottles to buy.

LARQ Bottle PureVis
The best overall self-cleaning water bottle
Marketed as the first self-cleaning water bottle, the LARQ Bottle PureVis is a premium option. But the features you get are reliable and backed by a 12-month warranty. LARQ actually offers two kinds of bottles. The Bottle PureVis is its insulated option, keeping water cold for 24 hours or hot for 12 hours. On the other hand, the Bottle Movement PureVis is a lighter, non-insulated model.
Both bottles use the proprietary PureVis technology, a UVC light built into their caps. LARQ shares that PureVis can eliminate up to 99% of bio-contaminants, including E. coli. To back this up, the company says that the technology is certified effective by the FDA and CE, among others. As for design, the Bottle PureVis is crafted from 18/8 stainless steel and is BPA-free.
You can activate a cleaning cycle any time on the LARQ with the touch of a button. However, the bottle automatically turns on every two hours for a 10-second cycle. And if you’re uncertain about your water source, the drinkware offers Adventure Mode, a stronger 3-minute treatment.
Sizes: 17 oz, 25 oz (PureVis), 24 oz, 32oz (Movement PureVis)
Technology: UVC | Battery Life: Up to 28 days | Vacuum Insulation: Yes(PureVis)
CrazyCap
The best self-cleaning bottle in terms of design
If you’re not willing to spend almost $100 for a self-cleaning bottle, then CrazyCap is a reasonable alternative. Its second-gen models are constructed from 18/8 stainless steel and use UVC light technology. Design-wise, CrazyCap differs from LARQ by offering a slenderer form. The bottle also comes in more color options — 17 to be exact — including patterned finishes.
CrazyCap is available in 17 oz or 25 oz sizes. In terms of performance, the company claims a 99.999% kill rate against E. coli. This, after using the bottle’s 2-minute Crazy Mode sterilization. However, a typical cleaning cycle of the bottle lasts only one minute and turns on automatically every 4 hours.
To ensure the battery has no contact with water, CrazyCap opts for portless charging. Its unique 360-degree portless charger is simply placed over the cap. Unlike other self-cleaning bottles, CrazyCap also sells its UVC cap separately. The company shares that the unit is compatible with most cola-style bottle brands.
Sizes: 17 oz, 25 oz | Technology: UVC | Battery Life: Up to 7 days | Vacuum Insulation: Yes
Mahaton Bottle
The best self-cleaning bottle for indoor use
Inspired by modern architecture, the Mahaton Bottle sports a sleek shape that narrows near the cap for an ergonomic grip. It’s made of 304 stainless steel and food-grade ABS for strength. The bottle also comes with a powder-coated finish for added durability.
Like CrazyCap, the Mahaton Bottle’s water cap is portless and waterproof. This also allows for wireless charging. In terms of cleaning, the product employs UVC technology as well. The company shares that the bottle can eliminate 99.99% of bacteria through its single, 90-second cleaning cycle.
With the Mahaton Bottle, you’ll have to start the sterilization manually as there is no auto-cleaning cycle. The bottle only comes in a 12 oz size, too, which may require several refills during the day. As for insulation, Mahaton’s self-cleaning bottle can keep water cold or hot for up to 4 hours.
Sizes: 12 oz | Technology: UVC | Battery Life: Up to one month | Vacuum Insulation: Yes
Sawyer Products Personal Water Bottle Filter
The best self-cleaning bottle for hiking
The Personal Water Bottle Filter from Sawyer Products takes a different approach to cleaning. Instead of UV, it uses a decidedly low-tech but reliable high-flow rate water filter. Sawyer shares that its bottle can filter up to 0.1 microns, ensuring no harmful pathogens pass through.
Because it’s filter-based and requires no charging, the Personal Water Bottle Filter is ideal for outdoor use. It’s particularly suited for cleaning water from natural sources like streams or rivers. Some contaminants it can remove include E. Coli, Salmonella typhi, bacteria, and plastics. However, the filter doesn’t have charcoal, so it can only remove small amounts of heavy metal.
As for design, Sawyer’s bottle has a 34 oz capacity. It also comes with a 63mm cap, two replacement straws, a backwash syringe, and an inline filter.
Sizes: 34 oz | Technology: Filter | Battery Life: N/A | Vacuum Insulation: No
Philips Water GoZero
The best self-cleaning bottle with a handle
As great as most water bottles are, there’s something different when it has a handle. It simply gives you more options on how to carry or secure the drinkware. This is what Philips Water GoZero offers and is arguably its distinguishing feature.
However, like most of its competitors, the Water GoZero uses UVC technology. Independent lab tests show the bottle can eliminate 99.999% of bacteria and 99.96% of viruses. You can also start a cleaning cycle manually or wait for the automatic UVC activation every two hours.
As for design, it follows the industry template, boasting an 18/8 stainless steel construction and double-wall insulation. With the latter, the Water GoZero keeps water cold for 24 hours and hot for 12 hours. Philips’s smart bottle also sports a powder-coated finish, making it sweat-free and dishwasher-safe except for the cap.
Sizes: 12 oz, 20 oz | Technology: UVC | Battery Life: Up to one month | Vacuum Insulation: Yes
Lavone Water Purifier Bottle
The most versatile self-cleaning bottle
The Lavone Water Purifier Bottle follows the UVC light trend as well. Based on tests, the unit can neutralize up to 99.99% of harmful bacteria and viruses. A cleaning cycle lasts for one minute and is intelligently activated automatically every 2 hours.
But the budget-friendly self-cleaning bottle does more than purify water. Lavone claims the cap can be used to sterilize various objects — from masks to keys, wireless earbuds to gadgets. How effective it is, however, is subject to scrutiny.
Like the other bottles in this list, the Lavone bottle boasts stainless steel, BPA-free construction. The double-wall insulation of the body keeps drinks hot for 12 hours and cold for up to 24 hours. The bottle is also IPX6 waterproof and is dishwasher-safe (except for the cap). Battery life is also impressive. A single charge of the product offers 30 days of use.
Sizes: 18 oz | Technology: UVC | Battery Life: Up to one month | Vacuum Insulation: Yes
Verdict
Self-cleaning bottles are eco-friendly drinkware that keeps your water and bottle free from germs and bacteria. In this review, LARQ and Philips are the standouts.
Choosing a self-cleaning water bottle can be a challenge. After all, the market offers a ton of choices. However, most self-cleaning water bottles have the same feature-set and design. At the end of the day, it boils down to reliability and battery life. In these two aspects, the LARQ Bottle PureVis and Philips Water GoZero stand out.
LARQ’s water bottle touts itself as the first with self-cleaning technology. While marketing claims can be debated, it’s hard to argue against LARQ’s reliability. With a premium price and a one-year warranty, its PureVis water bottles enjoy the trust of many consumers. Several institutions also vouch for the effective sterilization offered by its bottles.
The Philips Water GoZero bottle also scores high in our review. Although CrazyCap has a solid reputation, the Water GoZero’s battery life gives it the edge. A single charge of the bottle can last 30 days, an advantage given how similar its features are to competitors. The Water GoZero also comes with a handle, making it more convenient to carry.
