UltraPress® Replacement Spout Cap

Safer than not filtering and reduces bottled water.

Safer than not filtering and reduces buying bottled water. I haven’t tested all that it filters. I have used it sometimes at work when the water tastes funny, during boil water notices, and when hiking/backpacking. I do question on the purification part. I tested the water post filter with a TDS tester and the result is the same as tap water pre-filter. Not sure if that should be the case. I would still use and recommend the product with questionable waters. Especially if traveling in other countries.

Great to have a spare

Great replacement cap. Lost one once, now no worries!

You need to design a cap that stays attached to the lid. Overall a great product with a serious design flaw. If you lose that cap on the trail it’s big problem.
