Hi everyone,

just wondering if anyone can tell me about the chances that a proper water filter could be damaged by sub zero temperatures, e.g. get microscopic cracks which let water bypass the filter itself, without the damage necessarily becoming apparent, thus endangering the user?

What do the manuals say about this issue?

Has anyone experienced this – and realised?

What do you do with your water filter if you’re transporting it in sub zero conditions? It’ll be next to impossible to always keep it above freezing, and even on summer trips in higher altitudes you might well encounter freezing temperatures!

Additionally, that would probably mean that you can’t safely put a water filter in checked in air travel luggage, as you don’t know what temperatures the luggage will see throughout the trip…

That seems to be a serious concern and weak point of water filters that I never thought about before.

Cheers,

Matt
