If you have a common under the sink or above water filtration system that includes Active Carbon (granular activated carbon) filters and Reverse Osmosis. Most contain both, they are highly effective in removing PFAS.

> Most contain both Most installed water filters are not reverse osmosis because it takes up too much room, wastes a bunch of water, needs to be remineralized, is more expensive than a non-RO 3 stage filter, and is not significantly more effective than a 3 stage that includes carbon.

  What are the stages in a 3 stage filter? Do they really even remove anything? Think about it- if they aren’t removing minerals they aren’t removing things like lead, arsenic, chromium… It’s like a glorified Brita filter and doesn’t even lower the ppm of the water that comes out of it.
