UltraPress® Purifier Cartridge

Ran the first cartridge through a full 300 cycles with slightly cloudy tap water and it still kept the taste clean right up to the end. For the price per liter, that's solid value if you're not filtering heavy silt.

We live in a dusty area, so I was curious how long this cartridge would hold up. After about 25 cycles filtering cloudy tap water, the flow is still noticeably strong. The 300-cycle claim feels legit so far.

I’ve run this cartridge through about 20 cycles so far and the water tastes noticeably cleaner. The 40-gallon capacity gives me confidence it’ll last through our camping season without a swap.
