Great. The water tastes so good it definitely has increase my water intake. One point to note is that it does reduce the capacity of the bottle quite a lot so you'll need to do lots of refills but i don't mind this at all, the water tastes so good its worth it.

Just the FAQs

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 PFOA/PFOS, chlorine, pharmaceuticals, and more. (Filters are tested to NSF/ANSI 42, 53 & 401 standards). 1 LARQ Essential Bottle Filter replaces 189 single-use water bottles!

The included Essential Bottle Filter should be replaced every 25 gallons/94 liters or 2 months.

If you are using the Advanced Bottle Filter, replace it every 40 gallons/151 liters or 2 months.

LARQ Bottle Filtered uses Nano Zero filtration technology to remove chlorine, lead, heavy metals, 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 Filtered Cap to remove pollutants.

If you select a refill plan, LARQ will ship you a replacement filter every 2 months at the discounted rate of the perk selected. Your card on file will be charged prior to shipment.

Yes, you may skip or cancel your refill plan at anytime. If a refill plan is canceled, the discounted rate will not apply to any future refill plans.
