Hey guys. I've been reading up a lot on water filters and it seems to be even more "important" to get a shower filter too. Surprisingly, they aren't too expensive. Does anyone have any brand recommendations? Something which doesn't break after the first month? Currently I'm looking at one from Berkey (http://amzn.to/11YxZyb), which seems to be a very trusted brand and one from Pelican (http://amzn.to/1wg6MkL). The Pelican one has "three stages" of filtration, so it seems to be better, but I've never heard of the brand. Thanks for the input.
