How do I know when it is time to replace my LifeStraw Go Series filters?

The Go Series utilizes a two-stage filtration system consisting of a microfilter membrane and an activated carbon filter.

• The membrane microfilter lasts up to 1,000 gallons (4,000 L) and will stop allowing water to flow through once it’s reached the end of its lifetime. Replacements can be found HERE.

• The activated carbon filter lasts up to 26 gallons (100 L) of water with proper use and maintenance. We recommend replacing this when you notice a change in smell or taste of your water or every 60 or so days with regular use. Replacements can be found HERE.
