my water produces an almost unbelievable amount of scale. I have several misting systems; I decided to try a couple of other calcium inhibitor brands for a better price. One by one they all failed. most of the time they just scaled up or clogged. many times the threads on other brands were defective or did not match for some reason (made for other countries specs?). In the meantime, the system with the Water Sentinel filter kept working, no scale, no clogs. I wasted my money on those trials. Still wish that the price was not so high but I am back.

We'll see if it works
It makes promises that I hope it can keep.....Unfortunately it took a number of re-installs and a lot of professional teflon tape to keep it from leaking around the threads. I gave it 4 stars because I still have hope it will perform and the leaking could have been caused by the "made in china" fittings....

Better than the ones from the Big Box Hardware Stores
Bought one new from a Big Box hardware store and it never did cut down on the calcium stains on the plants and lawn furniture when the misters were on. This one works a little better, not as much on the stains.

Made in the US and saves my Outdoor furniture!
This works very well. I will not use my misters again without this. What a mess before I had this filter. Minerals everywhere! Since I attached this filter it’s not a problem any more. Plus! It’s made in the USA! Yea!

Works fairly well to extend the lifetime of mister nozzles ...
Works fairly well to extend the lifetime of mister nozzles in my very hard water area. Without it, the leaves of cuttings become covered with minerals & mist heads must be cleaned in hot vinegar very frequently--& it's impossible to completely clean them every time, so the hard water eventually ruins them.This typically lasts from spring until fall, when I most need it, before mineral deposits become noticeable again.

Works great
So far it is working with our mister on our back porch and helping with the hard water that would usually leave white marks on patio furniture. Will be getting another for sure

Works as stated
Great idea to keep the spray nozzles open.
