The MSR Miniworks is a great filter for the price. It is very reliable and easy to maintain. I usually find chemical treatment easier but when that is not a option the Miniworks is the way to go. The Hyperflow will pump more quickly but you definitely sacrifice durability and ease of cleaning. The ceramic filter can be used several times before it needs to be replaced.
