I stand corrected. Thank you for pointing this out.
I do think that the comparison should be based on the power consumption without the UV wattage since the FX6 and AC110 do not have these as an option but even then you are right. There would be a $54 difference per year in running each of them. This would equate to a slightly longer recoupe period of a hair under four years but definitely not as long as I originally thought.
Thank you for pointing out the electricity calculator. I have never thought to check for one of those online before.
I do still think the SunSun filters are a good choice, especially if startup costs are limiting but as you have shown, the long run cost effective option would be the FX6 and AC110. You just need the startup money to put into them.
This does bring me to the question of why the SunSun filters use so much power vs other filters with similar characteristics.
