The LARQ Bottle Filtered will include one LARQ Bottle Filter and a silicone detachable carabiner.
The LARQ Bottle Filtered is a portable water filtration system that combines a high-performance Nano Zero filter technology with a seamless, low-pressure drinking experience. As you sip through the straw, our Nano Zero filter removes a range of contaminants like chlorine, lead, heavy metals, PFAS/PFOS, mercury, cadmium, particulates, and more. (Filters are tested to NSF / ANSI 42, 53, & 401 standards by 3rd party labs). 1 LARQ Bottle Filter replaces 300 single-use water bottles!
LARQ Bottle Filtered uses Nano Zero filtration technology to remove chlorine, lead, heavy metals, PFAS/PFOS, mercury, cadmium, particulates, and more. While the LARQ Bottle PureVis uses PureVis UV-C light technology to neutralize harmful bacteria and viruses. One focuses on physically removing pollutants from water, and the other eliminates bio-contaminants in water. Our caps are interchangeable so you can use the PureVis Cap first to sanitize the water and then use our Filter Cap to remove pollutants.

- Non-insulated LARQ Bottle PureVis in 24oz/710ml

Our filters are designed to have 40% less pressure than comparable filters. It should provide a seamless, low-pressure drinking experience like drinking a smoothie.
Depending on your usage, the LARQ filter should last up to 2 months of use or filter up to 40 gallons (151 liters) of water.
Do not put the LARQ Bottle Filtered in the freezer, this may damage the vacuum seal of the bottle. The LARQ Bottle Filtered may be refrigerated but bear in mind the double-wall vacuum insulated feature of this bottle will not allow contents inside to be affected by external temperatures.
We recommend hand washing the bottle, cap, straw, and filter pod with warm water and mild soap. Before washing, please take out the filter from the filter pod.
We’d recommend giving your LARQ Bottle Filtered a rinse and wiping down the drinking spout and silicone pad every time you fill up your bottle to keep it in tip-top shape.
We’d recommend only using cold or room temperature water with the LARQ Bottle Filtered. The water should be from a potable source. Do not use with hot water.
The LARQ Bottle Filter does remove small particles, down to 40 microns in size.
The LARQ filter won’t significantly change the water’s pH.
- Remove the filter from the filter pod and dispose of the outer packaging.
- Rinse the filter under running water for 10 seconds (make sure it’s soaked).
- Push the straw into the cap base until it’s secure.
- Install the filter (tip facing down), and screw the pod cap on securely.
- Fill the bottle with cold or room temperature tap water and screw on the cap.
- Push down on the λ to flip open and start sipping. Enjoy!
It will remove some calcium that causes limescale but the main focus of our filter is to target heavy metals, chemicals, and VOCs.
No. We would not recommend using the LARQ Bottle Filtered to fill up from streams. If you do want to use it in the wild, purify the water first with the PureVis cap and then use it with the LARQ Bottle Filtered! Only use it with flowing water that is clear to the eyes with no heavy sediments.
Note: Filter is intended to be used with potable (municipal tap) water only. Do not use LARQ Bottle Filtered with water that is microbiologically unsafe or of unknown quality without adequate disinfection before and after filtration.
