I have 2 Ideas for enchantments.

One is that it would have compatibility with Robotic Parts (A Filter Implant)

And another, which might be there, is that pollution is trapped by blocks. Meaning that if pollution gets bad enough in you basement, you might not be able to breath, but you won't affect the rest of the world (A solid block is stone and the likes) Or you could make a massive wall around your base that will protect it, but has to go from bedrock to Height Limit.

Thanks!
