NORTHSTAR Pre & Post Conditioning Filter Review

I have reverse osmosis water for the refrigerator and a drinking faucet in the sink. I've been using these filters since 2014, the last ones are ok. 8-9 months depending on the number of people consuming drinking water. No problem, just uninstall in the right order and install in the right order.

Worked perfectly every time until the last time there were no black particles on the outside of the filter, I thought everything was fine, I was wrong, now I'm out of water for those Holidays and the weekend after. Be sure to have extras on hand, but they're expensive. Where's the quality control, mass production 🤔!

I have a Northstar reverse osmosis system at home. I replace both of these filters every six months when the orange light starts blinking. There are 2 adults and 3 children living in my house. Our water tastes great. Unscrewing and screwing in the filters is easy. Changing both filters and the battery takes less than a minute. My plumber told me to buy and install these filters myself. It's easy and it works.
