Review on 💧 Efficient APEC FILTER SET ESPH Capacity Replacement Water for Clean and Purified Drinking Water by Jonathan Abreu

This is the first time I have replaced these filters in my APEC ROES-PH75 system. I used my system for 14 months before changing the filters. The total exchange time was about 20 minutes. Make sure you are prepared for a water leak when replacing stages 1-3 as the filter housing is completely filled with water at each stage and cannot be drained beforehand. I took out the entire filter unit from under the kitchen sink and worked on the bath towel on the kitchen floor. APEC recommends replacing these filters every 6-12 months and the reverse osmosis membrane and stage 5 filter every 3-5 years. I was surprised at how much rust was caught by the first stage (I'm guessing that's the paint) since I filter city water. Water flows through this filter from the outer surface to its hollow center and then to the next stage. The inner column was as white as the new filter, so it definitely caught it all. I can't wait 14 months before swapping them again. Picture 1 shows a 14 month old Stage 1 filter next to its new replacement. The second picture shows stage 1-3 filters at the age of 14 months.
