Product review (5 stars): Be careful if you buy recycled filter containers
I bought replacement filters from ANOTHER company last time, and when I went to use it, the inside of the cylinder was cracked, which would have led to a flood in my kitchen. You couldn't see the damage until you took of the seal, and I might have missed it had I not looked inside. That other company obviously tore open old cylinders to replace the filter element.  Thank you JFL for sending filters really quickly that weren't brokenand work really well.  Learned my lesson to go for good value (these were a good price) and not just the cheapest.
