Edgar asks a crucial question. If you are thinking of dipping water from streams, you need a purifier, not a simple filter like the Brita.

I'm a fan of the Grayl ultralight bottle filter. I've used it primarily while backpacking and find it to be easy to use and effective. It's also rated to function as a travel filter when in places where it's recommended to avoid drinking tap water.

What do you use when hiking in the US (if that's where you're from)? There's nothing unique about the pathogens in stream water in Ireland. Go to an REI if you have one near you or any camping supply store for advice.

I'd only invest in either a filter or purifier - and I personally don't know if I'd trust the 2 linked examples for outdoor use - if doing VERY long 1-day hikes or multi-day backcountry camping that involves water from streams, lakes, etc. Tap water, which I read is perfectly safe in Ireland, is fine for your day-hiking supply; no filter needed.

We've done quite a number of long day hikes in much warmer climates than Ireland and done fine with just our tap-filled bottles (at least 2 liter-sized bottles apiece depending on length of hike and aridness).

Well to be technical, yes, there can. Different regions have different bugs, some have some rather nasty pathogens that may or may not be removed or neutralized by one method or another. But yeah, Ireland...probably nothing too exotic.

Different regions have different bugs....

If livestock are upstream, giardia is a possibility.

Chief pathways of human infection include ingestion of untreated
sewage, a phenomenon particularly common in many developing countries;
contamination of natural waters also occurs in watersheds where
intensive grazing occurs.

Mammalian hosts also include dozens of species, including cattle,
sheep, and goats.

And there is crytosporidium.

Zoonotic subtype families of C. parvum implicated in human infections
are commonly associated with cattle, particularly calves.
