The filter media is Hollow Fiber with a pore size of 0.2 microns. It has a flow rate of 3 liters per minute or 20 strokes per liter, and the cartridge lasts about 1000 liters.

Using the MSR HyperFlow Microfilter is a breeze. First, connect the filter to a water source. You can use the Quick Connect bottle adapter to connect it directly to MSR hydration products or other wide - mouth containers. Start pumping, and with just 20 strokes, you'll have a liter of filtered water. Since it pumps at a rate of 3 liters per minute, you can get a large amount of clean water quickly.
When it comes to maintenance, the good news is that you don't need any tools. You can clean it in the field multiple times to keep the flow rate up. Just follow the cleaning steps to ensure it works well for a long time.
However, there are some things to keep in mind. This filter is effective against protozoa, bacteria, and particulates, but it won't filter out viruses, chemicals, or toxins. So, if you're in an area where these are a concern, you might need additional treatment methods. Also, the cartridge has a lifespan of about 1000 liters. Although there's no cartridge replacement indicator, keep track of how much water you've filtered to know when it's time to replace the cartridge.
