"Bought this filter to outfit a guiding group in 2016. Out of the three that I bought all of them are still in operation after heavy use. As in most classic filters backflushing is a necessity and MSR did a good job describing how that process works with this one. Flow rate is slower when dirty water is present, but we connected them directly to the drom bags and would have 10L in about 10 minutes with clean filters. The weight and reliability is something that I respect from this filter. The bag and attachments are all wonderfully designed."
