  • Saved Me THOUSANDS of $. Hire a Plumber to Install
Style: 6-Year Whole House Salt-Free Descaler
Making sure the water coming into my home faucets, showers, hoses, and sprinklers is as pure as possible is very important to me. All city and well water has either chemicals for treatment and/or minerals that can reduce the life of appliances like dishwashers, water heaters, washing machines, and these chemicals and minerals are not good for your skin, hair, sinks, showers, and clothes. I originally called 5 different plumbers to quote me to install a whole house system that could address these issues. Prices ranged from $3000 to $10,000 installed. I did EXTENSIVE research including talking to my city water department to determine exactly which chemicals were added to treat my water. I also had the water tested to determine the amount of chemicals, minerals, and sediment that I was trying to remove from the water. After a week of research I found this product on Amazon that would filter most of my concerns for only $329. Because I have brand new appliances including two tankless water heaters, I wanted extra purification features. For this I bought separately the GOLDEN ICEPURE 3 Stage Whole House Water Filter System for $299. I'm fairly handy but was not comfortable installing on my own. I hired a plumber, and for $600 and they installed both units for me in about 4 hours. So, out the door I only spent $1200 for a great system! My family immediately noticed a difference in the shower. Everybody noticed their skin was softer and not irritated, soap and shampoo washed off easier, and clothes came out cleaner and softer. I like to wash/detail my cars at home and I noticed the water spotting was much less and easier to clean than before I had the system installed. PROS: 1. MUCH CHEAPER than a whole house water filtration system even when adding on additional filtration system. 2. Low profile for space saving installation 3. Works great and water tested showing chloramine, sediment, and water hardness removed 4. Saves money up front and long term by extending life of appliances that use water and are normally damaged due to mineral deposits 5. Skin feels better and not irritated 6. No salt to refill 7. If the power fails the system will still function as apposed to electric descalers 8. My wife is happy! CONS: 1. I would not attempt to install this on my own. Its not really supposed to be a DIY for the average home owner. My plumber said it was easy to install and I'm happy with that. This has been installed for 9 months without any issues. I will update the review if something changes. ... show more

  • Good filter housing with inexpensive replacement filters
Style: Pre/Post Filter + Timer
I purchased this to replace a Filtrete whole house filter. The price kept going up on replacement filters for the Filtrete unit, so when it got to the point where I could buy this filter housing and two replacement filters for about the same cost as one replacement filter for the other unit, I decided to just go with this AO Smith unit, and I'm very happy with my decision. A benefit of this unit is that you can buy replacement filters from many different brands, and that competition seems to keep the price for replacement filters down. This unit is rugged and comes with large diameter inlets and outlets. I had trouble finding threaded reducers to step down from 1" to 1/2" pipe from my local hardware stores, so I ended up buying the fittings on Amazon as well. Installation was easy once I had the right parts. My old Filtrete unit had a positive "stop" that prevented overtightening when installing the filter, but this one relies on you not overtightening. Apply a light coat of silicone grease on the o-ring before screwing the clear plastic housing back in. And only hand tighten the housing. Use the wrench only for removal, as you could easily overtighten it when installing. So far, I'm quite happy with this purchase. ... show more

  • Works fine for now, no build up but not a 100% cure for water spots and rings
Style: 6-Year Whole House Salt-Free Descaler
I just purchased the Descaler to see if it works without buying the rest of the system. We have very hard water with a PH of 8.2. We live in Florida in a brand new built home. The directions advise to also buy the pre-filter by the same company at Lowes. Look online for the PDF directions so you know what I mean, search ao-wh-dsclr_ownersmanual.pdf online. If I knew that I would have purchase the pre-filter as well but I did not install the pre-filter and figured I can install that later if I feel I still need it. This was just a test to see if it works or not and now that it is installed and I have tested it... I may go back and install the pre-filter to see if that gets me to 100% No watermarks instead of 90%. First impression after it was installed: PROS • Water feels GREAT! My son has sensitive skin and noticed his skin feels better after a shower and he is not itchy anymore. Great! it solved my sons skin problems. • Washing my crystal glasses shines like it never did before • Water has no odor • Water PH dropped to 7 range from 8 range. I was very happy to realize that after testing PH. My aquarium fish like lower ph and I have been trying to get the PH to drop for a long time with chemicals or Reverse Osmosis but neither was great long term). I was hoping the Descaler would drop the PH and it DID. My fish are happier and yes I can tell when my babies are happier. CONS • not easy to install if you have yellow pipes instead of PVC white pipes • Water has a weird taste - We don't care since we don't drink faucet water and only drink bottled water. • Not a 100% cure for hard-water and build up but helps about 90%. For the price It's good for now. It does not cure the water-spots 100%. If water sits on the granite too long it still drys with minimal water rings. Maybe nothing cures water-spots and rings, or maybe a full expensive system would cure 100% water spots and rings. idk. Installation was not easy. We had to configure pipes with elbows and two types of piping sizes. Our house was built with the yellow/creme color pipes which withstands heat better then the white pvc pipes. The problem was our builder put the inline pipes for the water-softer at the bottom by the floor and so we had to configure it going up and then into the tank. It was a puzzle to figure out LOL! Even though the yellow and white pipes state the same size they do not fit together and are off size, that was so frustrating and took a lot of trial and error in buying all sorts of pipping before we figured out what will fit together and how to do it. The directions are very vague and terrible!! No help to figure out what type of adhesive to use or how to fit the yellow pipes to the tank. Also the yellow pipes use a different adhesive than the white pipes. If you have the yellow pipes you need to make sure the adhesive you buy supports both pipes or it won't bond the pipes. ... show more
