Mitsubishi Chemical Cleansui CSP901. I purchased this but it didn't fit my faucet at home, so I'm selling it. I opened it once to try to install it, but it's unused. *As you can see in the fifth photo, the box was partially crushed when it arrived, but there is no problem with the product itself.* When shipping, I will remove it from the box. If you want the box, I will fold it and ship it.
