Filter lands can refer to two different sets of dual lands.[1] Their name describes the ability to take one mana and turn it into a combination of two colored mana.
Odyssey filter lands[]
The original filter lands were a cycle of lands that appeared in Odyssey. They each have an activation cost of and produce two mana of different colors of an allied color pair.
Shadowmoor/Eventide filter lands[]
Newer filter lands were previewed in Future Sight. The cycle of ten dual lands was finished in the sets Shadowmoor and Eventide. In Shadowmoor the cycle of allied colored lands were printed, while Eventide had the cycle of enemy colored lands. They each take one mana of two possible colors and produce two mana of any combination of the two colors that can be paid. They can also tap for mana.
They were reprinted in Oath of the Gatewatch: Zendikar Expeditions and Double Masters
