Hiker Water Microfilter

Good filter - heavy

This is a good filter but the only downside is the weight. It’s heavy

Dependable when it counts

Understanding the limits of this filtration system (and how it differs from a water purification system) is essential. Within its limitations, this filtration system is something I’ve trusted for years on various long outings in the wilderness. Having safe, potable water is essential and this filter has proven itself to me time and time again. I would recommend the pro however, due to its extended lifespan.

Great pump water filter. Replaced the one I had for ten years.

Reliable and Functional

Not as compact or lightweight as a lot of other "ultralite" filters out there. But this one can handle a lot of use and is simply more reliable. Before this, I used a simple screw-on model from a different company that would screw onto a disposable water bottle, but as soon as the threading on the water bottle got warped or damaged, I was stuck without clean water. Now I primarily use this one since even if certain parts break in the future, functionality will remain. Just a better design.

Great

I have used this on a lot of backpacking trips. It's so much more convenient than carrying tablets (which don't remove grime/particulates) or excess water. No matter what type of water we have put this thing in, the water always comes out clear and none of us have gotten any parasites or anything. Lightweight and doesn't take up much room in a pack. Great product.

workhorse

my last one broke... but after 15 years of solid service. no question to get a new one.

Solid but failed- might be operator issue.

105 miles on TMB, tour mount blanc, pumping water for 3. The “hiker” held up until the last day (9 days backpacking). I’m not 100% sure it was not me, or the glacier water I was pumping. It’s amazing how the taste of the water is maintained while keeping us safe. The pump side of the filter got some reside or dirt and we went from easily filling multiple Nalgene bottles in less then 5 min., to filling one every 5 min. That aside I would have done more research on expected capability and duration of trip. Many on the trail were using the single soft bottle / filter top from same company. Looks convenient, except for cooking etc. Overall I would use the product again, just be better prepared and educated.

Worth a little extra bulk for extreme efficiency and durability. When I was growing up, my Dad had one of these - it’s probably as old as I am and still works great (super easy to replace the filter at recommended intervals). Excited to carry on the legacy with my own now.

Another convert.

Can’t be beat- simple, easy, my young kids were able to master and use quickly.

Issue with leaking around seal.

I have had slow leaks around the seal from the beginning of use. I reached out to Katadyne, and they sent me a new housing and recommended I don’t over-tighten (the tightening does not take significant force before bottoming out) and lubricating the o-ring, but the issue continues. This makes me think it is an issue with the design. The product is still workable, but as one might guess, filtering water is already a two or three handed operation, so also trying to make sure the leaking part, which is untreated water, doesn’t leak onto something you’re trying to keep clean, is an annoyance. I’ve reached out to Katadyne again to see if they will replace the hiker housing with hiker pro, which I hope is more stiff (my guess as to why is leaks).
