AquaPure AQUA-PURE-AP430SS Cuno Hot Water Heater Scale Inhibitor System

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!

I hardly ever post reviews, but I must review this item. I purchased this in lieu of a water softener. I have very hard water and really didn't want to deal with salt delivery, so I gave this a shot out of desperation...with low expectations. Over the years, I've tried gimmicks on the market with 0.00% results (electrical coil thing comes to mind). After two months of use, I can say that this in fact does seem to prevent about 75% of hard scale build-up. Instead of hard to remove scale and large sediment chunks in my faucet aerators, I'm seeing more of a white dust. In removal of all my aerators for inspection, I'm seeing about 75% less hard clogging scale. My dish-washer also appears to have a white dust coating inside as opposed to hard scale all over the place. My wife says that the glassware is coming out of the washer much cleaner also. So far, so good. Not sure how long this "filter" will last, but I'm fine with the cost of replacement every couple of months if that's what it takes. Might last longer, not sure yet. Btw...I installed this filter right before water enters my tank-less water heater. Installation is simple...use Sharkbite PTC fittings, tubing and make sure to add a SharkBite ball valve before and after the filter. Pretty simple installation.

Perfect quick delivery and does its job so far no issues with the manufacturer or quality

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.
