User Review: MSR HyperFlow Microfilter
Price Paid: $99
I have been using this filter since it was first released. It has been performing perfectly since first pump, and at the first sign of "bogged down" filtering I back-flush as recommended and it resumes excellence. It also states to back-flush every 8 liters, which i also practice considering it only take about 3 mins to accomplish and is very simple.
The speed in which it delivers Poland Spring like filtered water is simply amazing. However, i have read several negative reviews pertaining to the filter becoming completely clogged and unusable. I looked into this dilemma and found that MSR has a phone number you can call to replace these faulty filters, apparently quite a number of them were put to market with sub par filtering performance. If you call them and give them the serial number off the filter, if it qualifies they will replace it with a more advanced filter for no charge.
I called and informed them that mine was purchased right about the time they came out and that i had no issues with the filter, they still sent me a new filter Just in case now that's customer service!
I highly recommend this product.
