"Does its job (not for long), and it's expensive."
This is the third year we've used these replacement filters in the Katadyn Base Camp water filter. The Base Camp is an excellent idea; fill the bag and let gravity do the work.
The filters are advertised as: "Provides up to 200-gallon capacity (depending on water quality)" I'm guessing you'd only get 200-gallons with clean, city tap water.
The past 3 years we've gone into the BWCA with 8 people for 4 days. We bring the Base Camp filter with 2 replacement cartridges. Each cartridge lasts for perhaps 25-30 gallons (~ 10-12 refills of the Base Camp bag). The water in the BWCA generally has a red tint (iron?) and there are always a few microscopic bugs, but I would still hope a filter would last more than 25-30 gallons. I follow all the directions that come with the filter with the hope of extending its life, but it doesn't really help.
I'd give this filter 5 stars if it lasted for just 100 gallons or were half the current price of ~ $33 USD.
On the positive side, the filter works - no one has returned home with a water-borne illness.http://tinyurl.com/katadynhikerpro
