These filters are new and never installed. The original packaging was opened/damaged so I removed them from the over size package to reduce shipping cost. I wrap them in shrink wrap and ship in box.

Made of white plastic with a carbon/charcoal filtration method, this filter is capable of removing chlorine taste and odor, ensuring clean and fresh water for your household.
