3M Home Water Filtration 3M IAS430SS - Appliance Protection System

It really works. Effective to the extent of 75% in removing calcification.

I live in a place with fairly hard well water, a septic system and no storm sewer. I've struggled with hard water scale build up for years. I can't put in a tradition salt-based water softener as I can't back flush. My research (as a chemical engineer) brought me to opt for a polyphosphate system. They are very affordable and super easy to install and manage. I have high hopes for this unit from 3M. It's downsides: 1) It seems very expensive for what you get. There's a metal Tee junction pictured above; it has some very fancy internals. There's a cartridge that you screw onto it. That's it; that's everything in the package. You can buy replacement cartridges for ~$40, so you're paying at least $60 for this metal Tee. 2) The price is highly variable, depending on when you look at it on Amazon. I've seen it as high as $130 and as low as $90 from this supplier. 3) The supplier ships via UPS and half the time, UPS can't find my house (they couldn't for this one). If you reliably get deliveries from UPS, this shouldn't be an issue for you. It was for me. 4) Polyphosphate systems aren't supposed to be able to handle "really hard" water. But there's no indication what the maximum hardness is to install this particular system (and I don't know how to measure the hardness of my water) The benefits, so far: 1) On day 1, there was a minor odour in my well water, but that went away by day 3. 2) I find softened water "slimy" somehow. This has not affected how soapy my showers are, or how the water feels. 3) In my short time using it, there appears to be a lot less scale forming on things like kettles. But it is early. Scale takes time to deposit and build up. I know how much I have been descaling various things in my house. Call me in 6 months. 4) It's super easy to install (or retrofit). Just make sure you have isolation valves on each side and a drain valve, too, as you need to shut water off around it and depressurize the line to replace the cartridges. 5) It's super quick and simple to change out a cartridge; 6) Replacement cartridges are widely available, and you can even get them from different manufactures, for about $30. I'm happy to spend $60 a year to get rid of scale. There are other copycat systems available (that use identical cartridges) that are cheaper. Given that what you're really paying for is the metal Tee, maybe they could be considered.

Installed a hot water on demand at the cottage, installed the aqua pure in the plumbing going to the tank. Since this is the first year it will be a while to see if there will be a difference. The filter does not impede the water flow, had a little issue threading the filter on the fitting (supplied), easy to cross thread, a little flimsy.

Este producto de 3M, en un par de semanas, me libro de las escamas de carbonato de calcio que se forma, al calentar en agua en el boiler. Una maravilla. Ahora aver cuanto me dura, porque dice que solo dura por un año... Espero que sea mas!

Be sure to flush the filter with something that doesn’t have a fine filters for 5-10 mins or so after installation. I have those electric smart toilets and it filled the bowls with little pieces black plastic and clogged their inline filters. Game changer in water quality. My showers and appliances are as grateful as I am. ZERO spots on the shower doors or sinks.

Excelente and easy to install
