Frequently Asked Questions

How do I maintain the HyperFlow filter in the field?

The filter can be cleaned repeatedly without tools for flow recovery. The field-maintainable design allows you to restore performance when flow rates decrease during extended use.

What containers work with the Quick Connect adapter?

The Quick Connect bottle adapter connects directly to all MSR hydration products and a variety of wide-mouth containers, allowing you to filter water straight into your bottle or reservoir.

Does this filter remove viruses?

The HyperFlow removes bacteria and protozoa but does not filter viruses. It meets NSF Protocol P231 testing standards for removal of bacteria (99.9999%) and protozoa (99.9%) throughout the filter life.

How fast can I pump water with this filter?

The HyperFlow pumps more than 3 liters per minute, or approximately one liter every 20 strokes, making it one of the fastest pump filters available.

What does the prefilter do?

The advanced prefilter screens out larger particles and sediment before water reaches the main hollow fiber element, extending the life of your filter and maintaining flow rates longer.
