How Long Does the LARQ Bottle Filter Last


Recently I purchased a LARQ Filtered Water Bottle and like a lot of people, I talked about being confused about how the water vessel works, for how long, and whether is it as good as my Yeti that I am extremely happy with despite the price. The LARQ uses a built-in filtration system but how long do LARQ filters last?

Depending on your household and local water quality, the LARQ filter should last up to 3 months of use or filter up to 60 gallons (227 liters) of water.

According to EPA-Bottled water, in general, is an excellent source of drinking water, but is subject to contamination if not properly protected at the source, during bottling operations, transit to retail outlets, and storage at home for this reason

LARQ Water Bottle

 

The LARQ Bottle PureVis uses PureVis™ technology to clean your water and bottle at the touch of a button. The bottle intelligently turns on every 2 hours to clean the water you put inside as well as the inside of the bottle. The LARQ Bottle PureVis comes with a micro-USB charging cable. Pretty cool technology that you definitely use out on the trail.

The UV-C wavelength emitted from the UV-C LED located in the LARQ Bottle PureVis Caps is optimized at the 270-275 nanometer spectrum to eliminate up to 99%* of bio-contaminants such as E. coli by breaking down their DNA before they have a chance to spread, improving the quality of your water.

At the minimum, the LARQ Bottle PureVis should be filled with water that is clear to the eyes and does not contain any physical sediment as the UV-C LED will not remove these impurities from the water. In other words, don’t put dirty water in the bottle.

The UV-C LED chip in the LARQ Bottle PureVis is smaller, more energy-efficient, non-toxic mercury-free, and more economical compared to traditional Mercury-based UV technology. *Based on the elimination of 99.8% of E.coli in a 20-second cycle for all LARQ Bottles. The company uses 3rd party independent laboratories for performance testing.

According to the manufacturer, the LARQ Water Bottle is 10,000 times more hygienic than regular reusable bottles. If you don’t clean your normal water bottle regularly, there is a risk of contamination. They claim by using the LARQ Water Bottle, you’ll save $1,000 per year by not having to buy bottled water.

The UV light water bottle activates self-cleaning for 10 seconds every 2 hours but you can also press the button for on-demand 1-minute water purification. When you’re traveling or out in nature and require more intensive sterilization, activate Adventure Mode for a 3-minute cleaning cycle which is the equivalent of boiling water for 20 minutes.

 

Does the LARQ Water Bottle Work

 

The bottle is made of food-grade, 18/8 stainless steel. While the cap, straw, and filter pod are made from a combination of silicone, polypropylene, and ABS. All of these materials are food-grade and BPA-free. According to the manufacturer, the LARQ Water Bottle is 10,000 times more hygienic than regular reusable bottles.

 How Long Do LARQ Filters Last?

If you don’t clean your normal water bottle regularly, there is a risk of contamination. You still need to clean your bottle they recommend giving your LARQ Bottle Filtered a rinse and wiping it down every 3-4 weeks or so with soap and water. They claim by using the LARQ Water Bottle, you’ll save $1,000 per year by not having to buy bottled water. The bottles used are:

  • Double-wall vacuum insulation
  • Keeps your water hot for 12 hours and cold for 24 hours.
  • Self-cleaning
  • Charge last 24 hours
  • Treats water in 30 seconds

Does the LARQ Water Bottle do what it claims:

Having been involved with water treatment for many years I have seen UV treatment work in Drinking Water and Wastewater treatment. The use of UV is a proven science that can deactivate certain bacteria and viruses that can cause illness. The LARQ Bottle keeps my drinks cold or hot as well as my Yeti. The difference is the use of patented UV-C technology to sanitize your water and bottle at the touch of a button.

The UV-C light in the cap of the bottle neutralizes and I think that is the keyword. It doesn’t remove them. The UV process is also affected by any solids in the water. Biological contaminants are broken down by destroying DNA-RNA but could leave the remnants in the bottle because there is no filtration at least in the Purevis LARQ that I purchased for $95.00.

I think it’s a very cool and efficient system (as long as the filter is changed on schedule) but I would wash out the bottle more frequently instead of their recommendation of 3-4 weeks.
