Bests & Worsts Reviews from Amazon

HTTAccessory sold the 6 pack and some of them are empty and water sprays out of the filter like a jet sprayer on a garden hose. HTTAccessory refuses to contact me to replace the defective filters. they are down to 65% positive feed back for the last year. so beware of HTTAccessory. the filters that do work seem to be correct, but who knows for sure what's inside of them.
