When I need a lot fast, I use the water that I bottled. For a glass of water, it's fast enough. It's a 2 stage filter system and this is an improvement over the 1 stage filter I had previously. I've used it about a month. I hope the water quality holds.
This filter got good reviews for removing harmful bacteria and chemicals from the water. The water tastes so much better than city tap water. The only complaint I have is that it's difficult/impossible to unscrew the housing to replace the filters especially side B (outcoming water) and side B leaks.
Pros: Easy to install, Good Capacity, Good Filtration, Removes Chlorine Taste, Slim Design
It is fine for my requirements and the water tastes better than the Britta. The drawbacks are: the stream is slow, the bathroom faucet is the only place where the plumbing would work.
