LifeStraw Go Series Water Filter Bottle

How to choose a water filter bottle
Match the filter to your water source. City-tap filters like Brita’s mainly improve taste by cutting chlorine, while hollow-fiber filters such as LifeStraw’s remove bacteria and parasites for wilderness or overseas use.
Consider material and insulation. Stainless steel bottles keep water cold and shrug off drops, but they weigh more than plastic; insulated models are worth it if you hate lukewarm water.
Check the filter lifespan and replacement cost. A cheap bottle with expensive, short-lived filters can cost more over a year than a pricier bottle with long-lasting cartridges.
Frequently asked questions
Do water filter bottles remove bacteria?
Only bottles with a microbiological filter, like the LifeStraw Go, remove bacteria and parasites. Taste-and-odor filters such as Brita’s do not, so choose based on your water source.
How often should I replace the filter?
It varies by model, but most taste filters last about two months or 40 gallons, while hollow-fiber membranes can last thousands of liters with proper backflushing.
