The factory box was in tatters when I received this filter head. I saved the label that was on it for identification purposes. The bad box had no effect on the item; it is still in new pristine condition.
It comes with a four-language information, use and care manual.

Everpure 433991 Details

Designed to fit all Everpure Claris filter cartridges, this Everpure EV4339-91 Claris Gen 2 single filter head can be used with your hot beverage, steam, or iced tea brewing equipment. This filter head is constructed of durable, corrosion-resistant material and comes with a 3/8" NPT connection. Its tamper-proof bypass is adjustable between 7 different positions with the use of a setting key.

This filter head has a valve-in-head design that allows it to depressurize itself during cartridge change out, while its automatic shutoff ensures that water doesn't spray everywhere when the head is opened. This system can be installed and operated horizontally or vertically, depending on available space, and comes with a mounting bracket.
