Features

  • Physical Anti-Scaling & SofteningSpecial alloy anti-scale stuff, included in the water softener, can fundamentally inhibit limescale formation to provide healthy water by preventing calcium and magnesium ions from precipitating and combining. The surface tension of the fluid after the water descaler system is reduced, can dissolve the aged scale and achieve the purpose of descaling.
  • Energy ConservationThis scale inhibitor inline water softener can protect your water heater, dishwasher, boiler, downstream pipe plumbing fixtures like faucet and shower head from scale buildup while improving the efficiency of electrical appliances, and extending their life. (Please choose the quantity to purchase according to your house equipment)
  • Safety & EfficientHelps to resolve hard water issues without the use of salt, chemicals, electricity or magnets. Retains the original normal minerals in the water, safe and healthy. Scale inhibition rate 86%, which helps to maintain high efficiency of water heater and avoid unnecessary electricity consumption.
  • 3-Year Long-lastingThe scale-removing and scale-inhibiting effect lasts for 3 years, maintenance-free. No need to replace the inner core of inline water descaler and no subsequent investment, save money and no annoy.
  • Rust PreventionTo form a certain thickness of ion protective layer on the water heater's wall surface, protecting the inner container and heating element, thereby avoiding safety incidents such as water leakage or electric leakage due to corrosion caused by scale rust. Same anti-rust effect on water pipes and water-related appliance.(1/2 inch connector, please confirm the size of the fittings for your device.)

  • Really works
Style: Q1
We have tried everything to filter our the calcium/magnesium in our well water. We didn't want a water softner. It's only been 2 weeks, but noticing no trace of these minerals on our equipment. We are pleasantly surprised that this item is working. Will update after months of use, but for now, this is an item you should try if you have had similar water problems. ... show more

  • A must have for RV
Style: K1
I live nomadically 6 months out of the year and many campsites have very hard water so this is a lifesaver for my water heater and certainly an inexpensive way to get a lot more years out of it. Inexpensive and very easy to install.

  • Nice And Simple Descaler
Style: K1
This little device can help save some big repair bills (due to lime sclae) down the road! Pros: 1. Multiple installation methods to provide descaling locally (at sink, toilet or tub) or whole home by installing on the cold water intake line for your water heater 2. Easy installation for the local applications 3. Doable installation on water heater install. This (working with water heater) is just one of those things that getsx3asier with experience. 4. Provides a noticeable differently in water quality pretty quickly 5. The cost benefit of this device is off the charts in a good way considering how effective it is when compared to larger filtration options and home appliance upkeep if you don't have anything at all. Cons: 1. Instructions are a weak point here but if you take your time this issue can be overcome All-in-all, I am very satisfied with this device and would recommend it to others even with the less than stellar instructions. ... show more

  • Q1 Whole House Descaler: Poor documentation
Style: Q1
The documentation for the Q1 Whole-house descaler was lacking, I had to contact the seller to determine what kind/size of pipe threads/fittings it connected to (3/4" NPT).

Literally took about a minute to install. So far appears to be preventing white scaling in my shower.

  • Defective Product
Style: Q1
This product does not work, the filter allows does not remove hardness ( I sent the sample to certified well water lab ) . They should have an option to return after 30 days allowed by Amazon since it takes a few months to see the results.

This filter is just one of those things where time tells how great it is at it's function. As far as installation goes... It was super easy.

  • Good Quality and solid feel
Style: K1
This scale and lime filter appears to be made of quality and has a solids feel about it. This inline scale filter does appear to be made of stainless still and nickel plated brass. At first glance for its size you may not think much of it until you pick it up. It has a wright a about it that tells you it is a quality piece. This filter appears to be easy install just place in piping running to you single spout faucet, whether that is a shower head, kitchen sink, bathroom sink and ect.. The filter comes in box as a one piece unit with instillation instructions. I will update this review over time once installed to describe the performance of the this piece. ... show more
