What water filtration to get?

[AllTheToddlers]

I have a water distiller but appreciate that only runs if I have mains power and I have an atom battery power bank but I don’t think that will lower the 4hours heavy drain the distiller users. I’m looking for something that can filter water reliably and easily for drinking water if needed. Life straw sufficient or something similar? Also wang to buy form somewhere genuine and not end up with a temu knock off

A LifeStraw or Sawyer Squeeze type filter is fine for personal use, but they're slow for a whole household, so a gravity bag or jug version is easier if you'd be filtering for several people. Worth knowing that these hollow-fibre filters remove bacteria and parasites but not viruses or chemicals, so for anything that might be contaminated (floodwater especially) you'd want to boil it or use purification tablets too. Buy from the brand's own site or a big outdoor retailer to avoid fakes. Alongside that, stored tap water is the simplest backup: about 3 litres per person per day.

Which purification tablets work? I’m a bit confused and don’t want to buy stuff that doesn’t work!

@Seriestwo there are two main types sold in the UK. Chlorine-based tablets (sodium dichloroisocyanurate, e.g. Aquatabs) kill bacteria and viruses in about 30 minutes. Chlorine dioxide tablets (e.g. Katadyn Micropur MP1) also deal with Cryptosporidium, but need a longer wait, up to 4 hours. Whichever you buy, follow the dose per litre and waiting time on the pack, strain cloudy water through a clean cloth first, and check the expiry date. Neither removes chemicals, so they're for doubtful water, not floodwater. Pharmacies and outdoor shops sell the genuine ones.
