This is my second under counter water filter and I can say it is an improvement over my 1 year (3 month old) cartridge. The pressure is about the same as without the filter, and the overall taste is much better. I didn't do a test in between, but I suspect this one filters out more. Overall I think the value for money is reasonable for a good filter so I would rate it a solid 4 star purchase. Just my thoughts, AK
