Review on High-performance Reverse Osmosis Filter System: APPLED MEMBRANES 50 GPD Replacement Filters and Membrane for 5-Stage Water Filtration by Julie Smith

I mentioned it (no problems yet) because we replaced them in just three months. Skeptical because the system is at least 10 years old and we couldn't find exact filters anymore. After extensive research they were the closest thing to our system and we wanted to risk changing the filters again to see if it was time for a new system. Well, as long as we keep our old system, the water flows great, the water is clean and tastes fresh. If the situation continues like this for the next three months, I will have no problem buying these filters again.
