User Review: MSR HyperFlow Microfilter

MSR HyperFlow Microfilter
Above: The current HyperFlow Microfilter, which may differ slightly from the version reviewed.

Rating: rated 5 of 5 stars
Price Paid: $99

This is the first water filter I have ever owned. I bought the only one in town, and based on all the reviews I have read of other products, I would not trade.

I took the HyperFlow to the Flat Tops Wilderness Area for 4 days. It was so fast that after the first trip to the creek for water, everyone in camp thought I had just dipped the bottles, bladders and a pot into the creek and returned to camp. I did not try to test the 3 liters/minute pump rate for speed, but it only takes about 20 pumps to fill a nalgene bottle.

After several days the pump action got harder indicating it needed to be backflushed. After backflushing, it seemed to develop a pressure leak at the end of the stroke on the intake backflow valve side. I need to check the seating of that valve to make sure I got it back in place correctly, but the pump continued to work well.

This pump is easy to use, and comes in a nice compact little package with the instructions for operation and backflushing sewn neatly into the bag. I have not seen a replacement cartridge for it on the market yet, but I should not need one for a long time. Thanks, MSR.
