The Manor Duo Water Softener + Taste Filter System is ideal for homes that are larger than 1,500 sq. ft. and experience symptoms of hard water and have bad tasting or smelling water in their homes.

NuvoH2O® Salt-Free Water Softener Systems uses a revolutionary technology that stands out in three ways. 

First, the NuvoH2O Manor Duo system retains the healthy ‘hard’ minerals in your water. Rather than removing and replacing hard water minerals (mostly Calcium and Magnesium) with sodium or potassium like old-fashion softeners do, NuvoH2O's proprietary citrus-based softening formula, CitraCharge®, bonds to these minerals making them incapable of sticking to pipes and surfaces.

Second, it further softens water by reducing the pH of your home’s water, bringing it closer to 7.0 or neutral. At this point, scale can’t accumulate on surfaces, in pipes, or water-based appliances. 

Third, the NuvoH2O Manor Duo Water Softener Systems REMOVE existing scale buildup that already exists due to a previous faulty water softener or the absence of one at all.

NuvoH2O Manor Duo Systems not only softens your home's water, but they also filter it, giving you bottled water quality water straight from the tap. With a 10-micron carbon filter, the added Taste System improves taste and water quality by removing sediment and chemicals including 95% of Chlorine, 95% of VOC, inorganic chemicals, and turbidity. The resulting water is soft and healthy for all your household uses, including drinking, bathing, washing, and lawn and plant watering. 

NuvoH2O Manor Water Softener + Taste Filter Systems provide a range of other benefits that extend beyond the taste and purity of your water. It helps you save thousands of dollars by extending the life of water-based appliances and water systems. It also prevents scale buildup and dissolves existing scale, all while being eco-friendly, compact, and backed by a satisfaction guarantee*.

    Just Received

    Published by Bill Livingston on 2nd May 2022

    Just received my initial shipment of Manor Duo Water Softener + Taste Filter. Currently in the middle of a remodel and will not be installing for a couple of months. However, I learned about this system watching Matt Risinger on the Build Show and based on his reviews, I can't wait to put it to use. Additionally signed up for the autoship cartridge program. I think this is a great program and know it will help me to keep my cartridge change out on a regular schedule.

    Published by James Grulkowski on 2nd May 2022

    This water treatment system has improved our water quality greatly. California water is very hard and does not taste good on its own. Nuvo H2o has done everything to make it better, Thank you for a great water filter and softener. James

    Manor Duo

    Published by Tom on 7th Mar 2022

    Love the simplicity. No hauling salt. Water taste & softness is fine. Only negative is some water getting everywhere during filter changing. Probably my fault more then the product.
