I've been using these filters for over 8 months now and they work fine when they work but the last 2 orders have been of poor quality. They don't seem to last as long as they originally did and the last order had to be returned due to flow issues. They got clogged and stopped working after a few weeks. Please note that I filter bottled water to remove fluoride so the water is already very clear. It can be seen that the quality has deteriorated. And now replaceable filters drip very slowly. These are expensive filters apart from the cost of the jug which was also expensive. I am very dissatisfied with this product and would not recommend it to anyone. There are doubts in the practice of service. Possible damage due to missing filling material in the box. Filters just bounce in the box. I am currently looking for an alternative. Don't buy from Revain!
