Katadyn Exstream/MyBottle Virustat Kit

rated 5 of 5 stars Great filter. Only imparts a slight iodine taste. I've used this setup for a few years to filter water on hikes up to a week long. I have filtered water from disgusting cow ponds and have never gotten sick. The flow rate is on the slow side, but it's a small price to pay for a great filtration system. This kit gives me enough confidence to drink water from pretty much any source if necessary. I find that the slow flow rate actually makes me drink more often and keep hydrated as opposed to chugging… Full review

Sawyer Cleaning Coupling

rated 4.5 of 5 stars A simple and brilliant accessory for the Sawyer Squeeze filter that allows one to improve back-flushing success with a device that is smaller and weighs less than the syringe provided for this purpose with this filter. At a price just south of USD $9, it's doubtless overpriced but still well worth it for any Squeeze users. Background Sometimes less is more, and sometimes experience allows one to "smooth it" in the woods, to borrow a phrase from nineteenth century outdoorsman and conservationist… Full review

Katadyn Carbon Cartridge

rated 4.5 of 5 stars This is a fairly inexpensive, simple, upgrade/add-on for filters such as the Hiker, Hiker PRO, and even the older PUR models. I recommend this product for anyone using those models, especially if you are getting water from a source that is used by recreational watercraft, or the source water has a bad taste or odor. Trailspace has two (2) group headings for this product, under different names. This product is currently called the "Katadyn Bottle Adapter with Activated Carbon" on Katadyn's website. Full review

Katadyn Hiker/Hiker PRO/Base Camp Replacement Element

rated 4 of 5 stars REVIEW/REPLACEMENT WALKTHROUGH: A simple, easy to replace cartridge. With replacement, this will upgrade your Hiker model to the Hiker Pro! Added field serviceable filter protector extends filter life in murky conditions. 4 stars only because I think the replacement element is pretty expensive. Servicing my 20-year-old PUR Hiker this weekend, I decided to post a walkthrough of the filter cartridge replacement. This kit will maintain all PUR and Katadyn Hiker/Hiker PRO models. This model of element… Full review

Sawyer Water Filter Squeeze Pouch

rated 4.5 of 5 stars Light, easy to use, we came up with a few solutions to some of the downfalls Weak bags and dripping bags in rivers. We found the  Filter Squeeze Pouch system easy to use, But dripping the bag in to the cold stream first thing in the morning was not fun. We found storing the system into a 1 gallon heavy duty ziplock bag allowed us to fill the bag and pour the water into the filter bag. The other downfall is we have had the squeeze bags break. Sawyer does not support this failure of their product… Full review

Sawyer Water Filter Squeeze Pouch

rated 3 of 5 stars Great concept of a system. Water filter itself is amazing. The bags lack strength and durability. They are the weak link in the system. The bags work fine and as advertised, until...At least for the 32 ounce size, both my daughter's and my bags failed when dropped when full. She dropped hers onto a snow bank from about 2 feet, full, and mine -- essentially brand new -- slipped from my hands at about 4 feet. They both failed at the top seam next to the bottle neck. Filter, I love, but Sawyer is hands… Full review

MSR Sweetwater Silt Stopper II

rated 2.5 of 5 stars I use this in a gravity-filter system before my Sawyer filter, to prolong the life of the Sawyer filter. I have mixed feelings about this thing. It works, in that the filter pulls out lots of sediment so that it doesn't get through and clog the main filter. But it almost works a little too well. I always pick the cleanest water I can find, and even after about 8 liters (4 plattys full) it becomes so clogged that water stops flowing. I suppose without this inline, I would just be clogging my main… Full review
