THE QUICK TAKE

Is it right for you?

Choose it when your compatible Peak reservoir is still sound and its filter needs replacing. You keep the bottle or gravity setup you already know instead of buying the entire system again.

Skip it for a LifeStraw Go bottle or a need for virus protection. This is a specific membrane microfilter, not a universal LifeStraw cartridge. It does not remove viruses or dissolved salt, and slow flow may first need proper cleaning.

01 / BUYING NOTES

Before you buy.

01

Match the thread to the system.

Check that you own a Peak squeeze or compatible gravity microfilter system. Similar branding does not make Go-bottle cartridges and purifier filters interchangeable.

02

Keep the clean side separate.

Filter into a clean receiving container. Keep untreated water away from its rim and from the outlet; clear-looking water alone does not establish safety.

03

Gravity uses the same replaceable membrane.

The filter connects below a compatible Peak gravity reservoir. Keep the reservoir and hose if they are in good condition; neither comes with this replacement.

The membrane is replaceable in Peak squeeze and gravity systems. It filters bacteria and parasites, but its microfilter is not a virus-removing purifier.

LifeStraw

Manufacturer fit and filtration limits · summarized

Reduced flow can come from trapped air, sediment or a dry membrane. LifeStraw advises its cleaning and backwashing procedures before treating every slowdown as a failed filter.
