Filter set (both 1 & 2) for Revelation 2 and all Genesis models including the EOS Genesis Platinum, the EOS Genesis Platinum 9, the KYK Genesis 25000, and the KYK Genesis 30000.
These filters work for the older KYK Genesis Models as listed above, but the newer model filters sold by KYK do not work with old KYK Genesis products because the older KYK Genesis products were made by EOS and KYK makes the filters for their newer models and not for EOS Genesis Models.
Replacement Filter one is good for about 4000 liters or 1142 gallons and should be changed at least every 6 months. Replacement Filter two was meant to last about 8000 liters or 2285 gallons and we suggest changing it about every 12 months for the best filtration.
When you buy a machine its not a bad idea to order an extra set of filters to "keep on hand" for that unexpected time of need.
