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.

Go Series replacement filters are available at LifeStraw.com and through many of our authorized dealers both online and at physical stores. 

HERE is a link to the membrane replacement which includes a carbon. 

HERE is a link to the carbon capsules sold separately in packs of 2 and six. 

To find a retailer near you, we recommend visiting our Store Locator tool.

If visiting an authorized dealer, please call the store or visit their website for inventory availability.

Please note: When buying a replacement membrane microfilter, ensure you are getting the correct replacement for your version of the Go Series bottle. Lids with the flip up straw will need a press-fit filter. Lids with a twist-on mouthpiece and lid require a screw-in filter.

We recommended washing your LifeStraw Go Series bottle by hand but if needed, the Go Series bottles can be placed in the dishwasher for cleaning, but only after the filters are removed and you should avoid the heated dry setting. It is recommended to remove the cover and mouthpiece from the main cap and wash them separately.

Please see our video guide for proper procedures on safely and effectively washing your bottle.
