Filters water faster than any pump I've ever used with the exception of the Timberline but with better results, 0.3 microns compared to 1 micron for the Timberline. Glass fiber filter element, depending on use, lasts for many seasons. Durable & easy to assemble. The only downside is it's weight, 11oz dry & 14oz after use. Still a small price to pay for good, clean water in a flash.
