Overview
A membrane microfilter and a carbon filter work together inside this LifeStraw tumbler to treat tap water and ice. Double wall stainless steel provides the insulation, and the slim body fits most car cupholders.
Everyday filtering without a separate pitcher is the reason to consider it for commuting and errands. The limitation is the short carbon filter life, and the listing gives no hold times for hot or cold drinks.
Who it's for
Drivers and office workers who fill up from taps of varying taste will benefit from the carbon stage. Anyone treating untreated outdoor water, or wanting listed insulation hours, should read the manufacturer notes first.
Pros and cons
- Filters bacteria and parasites

Performance notes
Water passes through the membrane, which blocks bacteria, parasites, microplastics and sediment, and the carbon filter then reduces chlorine, odors and organic chemical matter. The double wall construction slows heat movement through the body.
