The water from the APEC ROES-50 system gave me a sore throat after a few seconds of drinking. Tested with a PPM meter and showed under 10 (which is normal compared to when I first got it and the water was great). I knew these couldn't be the first 3 levels as they were recently changed. After replacing the 5th stage, my throat doesn't itch anymore. Also, installing the 5th stage was easy.
