Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews
Rated 5 out of 5 by from Guardian Gravity Purifier Bought this purifier for a basecamp location with stream water in North Wales mountains. Quickly got an efficient system in place filtering 10 litres every day for next days use. This product, when used as demonstrated on the MSR website is a game changer for our camp, saving time and fuel boiling water for drinking and cooking. Used every day for 5 weeks so far. Just back in civilisation and Wifi for a few weeks so about to sterilise it.

Rated 5 out of 5 by from Grand Canyon in January. 25 days in the Grand Canyon. We settled the sediment, filtered through fiber and .5 paper filters then purified about 10-15 leters per day. Simple, predictable, easy and effective.

Rated 1 out of 5 by from Super slow!! - promised to be 2X faster than other bags, no, it’s 5X slower - its super heavy and not clean bag included - the filter unit never dries even though i leave it on my dish rack.

Rated 5 out of 5 by from Works perfectly and is quickly becoming one of the most important items in my kit. With the increasingly more common water issues ongoing in parts of the country, it would be a smart idea to invest in this purifier. All I can say is that I am very happy to have not just a water purifier, but this model specifically.

Rated 3 out of 5 by from Effectice purifier with one big drawback The MSr Guardian Gravity Purifier is a great, effective filter for backpacking or car camping. The one major drawback is that the hose leading out from the purifier is way too long. Once filled, a 10 liter purifier is extremely heavy, and in order to hang it up high enough to easily use the hose means that you much have some who is REALLY tall or through use of a stepladder or some other such contraption. If the hose was a little bit shorter, it would be the perfect purifier. As it is, the purifier is only a 3 star produce.

Rated 4 out of 5 by from Intuitive and easy to use Very intuitive to use, although the top doesn't seal very well (which means it works best if it is hanging somewhere very high up and not moving at all). Flow is decently fast (like a pot of boiling water, it goes faster when you aren't watching it). Needs to be hung pretty high up though, which can be hard if you are vertically challenged.

Rated 5 out of 5 by from Best filter on the market I’ve used it three times now and this thing filters quick, I go over landing all the time and use it to replenish my water wife was a little skeptical at first but after reading about this filter she was perfectly fine with it like I said one of the best on the market

Rated 5 out of 5 by from Solid Product Purchased this about 6 weeks ago and have been camping/backpacking three times with it. It has worked well, it really filters water faster than other gravity filters I've used. I really like that you don't have to backflush with this filter. It packs down nice and compact so it doesn't take up a lot of room in my pack. Overall, MSR makes quality products and this one is no different.
