SAWYER PRODUCTS SP181 All-in-One Squeeze Filter, SP2129 Micro Squeeze Filter, SP129 Squeeze Filter, SP131 PointOne Squeeze Waterfiltersystem (SP131 PointOne Squeeze Waterfiltersystem)

This item did not live up to my expectations and the seller does not respond. This is a very expensive piece of plastic and even with the various adapters that I paid extra for it fits only one type of bottle. The tubing that is supplied with accessories seems hardwearing but is the length of my hand. Dont expect to get creative with this kit. I suggest you look for suppliers who provide higher quality filters at better prices and respond to customers. They exist.

Outstanding filter.Used it on the Coast to Coast walk in England. Wild camping for 17 nights.Filtered dirty, still pond water. And made it perfectly fine drinking water.Removes about 75% of the taste.Easy to clean too.Much better than the Kataydn Hiker I used last year. Which couldn't filter dirty still water.MSR Miniworks is also an outstanding filter.Filters dirty water.But much more on the heavier side.

The product seems be well made but I feel is somewhat over priced. I cannot comment on it's performance as we are in lockdown and I haven't been able to test it in the field. Other reports show it to be excellent though.

I gave up on my MSR Trailshot filter as it was painfully slow. This is much better in every respect! Filters so fast there's no hanging around! Not tried it as a gravity filter yet but I expect it won't disappoint. Highly recommended 👍

Bought these for use with our Scouts, they love using them and as leaders we loved seeing all the rubbish it filtered out when we flushed them out!

Quality product well made and easy to clean quick to filter water and light weight. Only problem is bags are a bit fragile so be careful when filling them up but apart from that a great product all round

Bought for wild camping here in Scotland and it's perfect for my needs

This is a must have item for clean drinking water, light weight, easy to use
