Made in USA Waterdrop Alkaline Water Filter - Comparable to Multipure Aqua Pura

Made in USA Waterdrop countertop alkaline water filter. NSF/ANSI 42 & 372 certified, faucet-mounted type.

This is a popular model that is currently sold out on Amazon. I personally imported it from eBay for over 20,000 yen including shipping.
It was opened and water was run through it once for a function check, but it has since been dried and stored, making it almost unused.
I am selling it because I no longer have a use for it.

It is a countertop, faucet-mounted type similar to the Multi-Pure Aqua Dome, so installation is easy. A lever attached to the faucet allows you to switch between tap water and filtered water.
Multiple adapters are included, so it will fit most faucets except for specialized ones like the one shown in the 3rd image.
Here is the manufacturer's product description:

[For Your Health]
The filtration process adds beneficial minerals like calcium, magnesium, and potassium, which is normal for an increased TDS reading (tested by a third-party lab).

By using only safe materials, you can obtain clean and healthy drinking water.

Using advanced filtration technology, the water flow rate can reach up to 1.6 gallons per minute.

[Multi-Stage Filtration System]
The 5-stage filtration system can effectively reduce up to 99% of colloids, sediment, and chlorine, as well as common impurities found in tap water.
It also reduces heavy metals, hydrogen sulfide, and fluoride, providing safe, delicious, and fresh drinking water (tested by a third-party organization).
