Frequently asked questions
CLEANR SIP uses two filters to give you cleaner, better-tasting water wherever you go. The microplastics filter is designed to capture microplastic particles, while the chemical filter helps reduce contaminants such as PFAS, heavy metals, lead, pesticides, pharmaceuticals, and more that can affect the quality of your water. Chlorine is filtered out to improve your water's taste and odor.
CLEANR SIP is designed to work with a wide range of reusable water bottles using an adjustable straw system. [View our detailed Bottle Compatibility Guide] to view your bottle.
And if it doesn’t work with your bottle, you’re covered by our 30-day money-back guarantee.
CLEANR SIP uses two filters with different replacement schedules. The chemical filter lasts approximately 3 months, while the microplastics filter lasts approximately 1 year.
Your pre-order includes two chemical filters and one microplastics filter, so you can use CLEANR SIP for 6 months before needing to purchase your first replacement filter.
CLEANR SIP is designed to be easy to clean. The straw components are dishwasher safe, so you can clean them along with your reusable bottle. The replaceable filter components should be removed before washing.
When you pre-order CLEANR SIP, you’ll reserve your unit at the full purchase price, but your card will not be charged until your order ships.
CLEANR SIP units are being manufactured now, and pre-orders will arrive to you between December 1–15, 2026.
