I recently purchased a 5 pack of atomizers and two of them had a weird taste to them after they were broken in. They almost tasted like the filter filling(blue foam) was burining. but, it wasn't the filter because I changed atomizers and it tasted fine. I tried soaking them in hot water and still have that taste to them. Has anyone experienced this? They work great but just put out that horrible foam burning taste. Any suggestions would be great!!!
