I almost got one in woodwork too!

I could have put all that, I got my O' Level Biology too, but went for the short version :-)

Hey Phil, in that case bring your tools and you can build new bridges across burns for us all as we go! (Payment in liver-damaging liquid, of course)

I have never filtered water West of Tarfside on the TGOC. But avoid any water where there is evidence of livestock or it is not fast moving.
I currently use either a Sawyer http://www.superdelios.co.uk The Delios has a finer filter but the Sawyer is easier to use.

With the Sawyer and Delios you squeeze water from the bottle you filled up in the stream. Be warned you can still get cross contamination. Wipe down with a rag the whole thing before filtering to prevent contaminated water dripping into your clean water. I used a Sawyer in the USA and still got ill. Also never blow the back end with your mouth to flush out excess water. As that is contaminated water potently. Use the squeeze bag to blow air through the filter to clear it out.


The Delios cleans peat stained water better I found. But has a slow flow rate. The Sawyer is way better all round and not expensive.

I currently use either a Sawyer or Delios if I think water may need filtering. Especially in the East, or Peaks.

According to the info on the web sites, the Delios has a 0.2 micron filter and the Sawyer (mini and squeeze) a 0.1 micron filter. Both are good, but as Andy says, the Sawyer is easier to use and has a faster flow rate. It also lasts longer and can be back washed with a supplied syringe. Recommended.
