One of the more expensive models, perhaps the most expensive. Definitely heavier than many other models, because of its stout aluminum construction. Very little or no plastic. This filter is built like a tank. Very large filter area. Very easy to use, cranks out a lot of water. The best thing, if you need to depend on a filter, this one won't let you down. I had a cheaper filter and used it on many trips and it was fine. I moved up to the Katadyn for the peace of mind. This filter is one you can DEPEND on.
There is no doubt, this is the last filter I will ever have to buy. Couldn't say that about many of the other models out there. I use it for 2-3 people on 9 day trips, twice a year, in BWCA/Quetico. Hate the price, love the filter.
