excellent water filter and seems very robust

arrived quickly This filter is used extensively by backpackers etc. you can take questionable water from puddles, streams, ponds etc and run it through this filter and it will be drinkable I like that in can backflush to clean it out and prolong the life I like that any standard plastic soft drink bottle or shop bought water bottle can be used to collect the water to be filtered and screwed on to this filter, squeeze the bottle upside down and clean drinking water comes out the filter. This does filter out cryptospiridium to 99% which is as good as any filters claim to achieve, and this is a fraction of the cost of many others A huge advantage of this is that it is so small and portable. ideal for home backup or emergency use. Highly recommend backflushing this to clean it every time its used to clean dirty water. eg always filter 500ml more than what you need and backflush it with the extra 500ml to keep it clean. let it dry thoroughly after use so inside doesnt grow mould and bacteria dont let it freeze, though this seems bombproof, freezing will destroy the filter. so if you find yourself in freezing conditions, keep it close to your core body warmth, perhaps in a ziplock bag in your pocket

Amazing water filter. I've used this water filter all over the UK with no issues. As long as you are following the general ways of what water to use and not (use fast flowing water from the highest point possible), I've found it to be perfect. I've used it without issue with heavily polluted Peak District water and with visibly polluted Fenland river water. 6 months into mild use and no issues.

I have been using a sawyer mini for about 8 years now so replacing it was a revelation. Much much better flow rate. I mostly use it as an online filter on my hydration bag. This filter has screw in adapters, and they do not really fit that well. It is hard to get a seal, so you either suck air, or it leaks a bit. I feel like it is only a matter of time till I get a backpack full of water, so I will be using some silicon to seal the adapters in place. A great filter with poor design and engineering.

Excellent bit of kit. Really good flow rate (puts the mini to shame) and easy to use. Definitely recommend this filter.

Used this for a 3 week trek in Nepal last month. Very glad I chose this over the BeFree/alternative options in the end — it's extremely light to carry in a day pack (and comes with a light drawstring bag to carry the different bits and pieces), filters pretty fast, and most importantly should last a long time with proper care. Note that many other filter options need to be replaced after a certain amount of time, so theoretically this is the more sustainable option. Oh and I didn't get ill from a multitude of water sources — so the filter most likely did its job! In the UK you can find a few plastic bottles that pair with the Sawyer thread (search Reddit for this if needed). However, I found the plastic pouches that came with the filter to be much more convenient. These roll up flat and take up much less space than a water bottle would in your bag. Highly recommended!

I’ve used this a couple of time now using water from Scottish mountain streams. In that respect it works well & I’ve not been ill from drinking the filtered water. However the bag leaks from the cap end. I’ve tried a couple of different caps with the same results. So if you are not going to filter the water immediately into another bottle, be careful about storing the full 16oz bag in a rucksack as any pressure on it will push the water out. Also, better to keep the 16oz bag upright if full, this helps but not so much. Will try other caps to see if there is a better seal. Or screw the filtration device on the bag, and put a cap on that. That might help too.

Great filter, I already own a mini and micro squeeze and fancied something with a faster flow rate. Good size, easy to use. An excellent and portable filter. I have no doubt it will give me good service.
