We have two of the same gauge large filters: composite 20 micron fiber with 10 micron carbon/coal.
I think you need a 2 micron filter as the last filter in addition to the UV light. While many recommendations is to change the UV bulb every 6 months, one place in Hilo said that once a year is fine. But, I've read that the bulb still may not purify the water as well after about 6 months even though the bulb still lights up. The effectiveness decreases with age.
