Katadyn MyBottle Exstream Cyst Filter - 2-Pack Kit

Always have clean, crisp water on your extreme adventures.

Be prepared for a clogged filter in your three-part Personal Exstream Water Purification Systems with two extra Katadyn Exstream Cyst Filters. As the cyst filter is the only part that can clog and tends to do so quickly when you frequently filter dirty water, Katadyn offers you two replacements for your Exstream bottle.
