Rated 3.0 out of 5.0 by FLGUY I hope it works
This little filter is supposed to reduce calcium build up from hard water. There is no way to tell if it works and no guarantee to replace anything should it fail and your tankless water heater be destroyed as a result. It has a proprietary threading and hook up so you can't easily put something else in line if it turns out to be useless. As a result, I can't really review it. If it protects my hot water heater then it's a good investment. If it doesn't, it isn't.

I bought on my own and gave to my plumber friend to add to my line if he thought it was worth it. He stated it was a good thing to add to help protect my tank less system. I'll do anything to keep that tank clean and operational, glad Home Depot on-line recommended it when I purchased my tank.

Rated 5.0 out of 5.0 by Sbuilder Compact and nice looking.
Although it seems I reviewed this product once before (second one installed) I was once again impressed by the quality an ease of installation. The siphon type tee fitting is stainless steel and will clearly last forever. Time will tell how well the product will protect the water heater but as it is not really a filter but a siphon feed element it will not impede the flow of water when it is used up!

Rated 5.0 out of 5.0 by BumMan Works as advertised...
The Aqua Pure Inhibitor was purchased to minimize the scale buildup on our new tankless water heater. It must be working because our dishes show much less of the white film when removed from the dish washer.
Installation was easy. I can be installed and pointing in any direction.,

Rated 3.0 out of 5.0 by eng99 Hot Water System Protector missing information
This unit works on a siphon principle and depends on a large volume of water passing trough the 3/4" water line to draw the chemical out of the canister. That fact is not found anywhere in the desciption. Gallons used at the necessary and stated flow rate to canister depletion should be provided in the description.
