Replacement Foams for EF-Booster

Bought this three-pack because the old foams were getting clogged unevenly; refreshing all three grades at once made the canister feel like new again. The fit is exactly right and the airflow is noticeably more consistent now.

I was surprised how much better the airflow felt after swapping all three grades at once—definitely a smarter way to refresh the whole canister. The pack makes it super easy to keep everything consistent without mixing old and new layers.

Finally got around to replacing all three foam grades at once, and the airflow difference was immediate—much smoother than staggering swaps. The pack made it easy to do the whole canister in one go.
