Katadyn Exstream Cyst Filter
Where to Buy
Here's what other sites are saying:
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.

The Cyst Filter attaches to the middle of your Exstream ViruStat microbial water purification cartridge and can be replaced repeatedly throughout the life of the ViruStat microbial water purification cartridge. It removes pathogens such as protozoan cysts (Giardia and Cryptosporidium) and particulates larger than 1 micron. A must for extended travel in regions with questionable water quality.
