LOL, you know so little. We sell thousands of products that customers ask for. Our magnetic modules are built in the USA, but thanks for knowing my business better than me. Somebody has obviously not been feeding the troll lately.
Since I work for one of the larger magentic water conditioning manufacturers, I will tell you the same thing we tell all of our customers. If you are looking for an inexpensive high quality water conditioner, not softener, the carbon tanks with hydromagnetic modules are the lowest cost alternative. Magnetic water conditioning is contreversial but it has been shown in some applications to be somewhat effective. My recommendation is if you do not want a softener, dont like the "Slimy feel" and you do not want to deal with 50 pound bags of salt, these units are fine. They will not soften the water, but they will make the water taste great, and they may help with some of the scaling, but we do not guarantee it. I highly recommend using a teaspoon of Lemi-Shine in the dishwasher for every load, and rain-x on the shower doors, faucets, etc once a month.
Electromagnetic water filtering for iron is not used that I am aware of.
