What people are saying
4 quotesDirect organic buyer opinions about Waterdrop K19 Countertop Reverse Osmosis Water Filtration System, filtered for spam and ads.
The main reasons why I love this Waterdrop RO is that you get instant RO water with no need for a reserve tank . It's a lot faster
The waterdrop might look nice, but when choosing a RO system, it's important to put stability and performance first.
Loved the filter at first, especially the instant hot water. However, after a couple months of use my wife started saying water smelled “fishy”
The unit works well for about a month , but then starts to fail— either not dispensing water at all or dispensing as little as 100ml over 15 minutes
