The Calcium Inhibitor Filter protects your misting systems by preventing potentially clogging solid sediments from passing through the system. It filters our particles as small as 5 microns, which is smaller than a human hair. Additionally, the filter coats smaller particulates with polyphosphates that enable easier passage through nozzles without forming blockages. Annual filter replacement is recommended and will prolong the life of mist nozzles.

  • Keeps mist cooling system operating at its best
  • Prolongs nozzle life by preventing solid particles from clogging nozzles
  • Helps eliminate clogging when used with auto drain valves
  • Recommended for use with all outdoor mist cooling systems

Rated 3.8 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by It does a good job I've used this product several times. It prolongs the amount of time that I can use the misting system before I have to remove the nozzles and clean them. I use a new one at the beginning of every season. July 31, 2012
Rated 4.0 out of 5.0 by System works perfect with the new filter Great product. Easy to install. significantly increased the flow on the mister system. August 17, 2013
Rated 5.0 out of 5.0 by Not just for misting This is a replacement. We live in an area with VERY hard water and our drip lines got calcified to the point that the heads were constantly clogged. I replace this filter yearly and have no problems. Saves time and money not having to replace drippers. September 16, 2014
Rated 5.0 out of 5.0 by Product Fit Perfectly Product Fit Perfectly! That is part of the battle! I won't know if it prevents clogging of mister jets until some time has gone by, however..... June 25, 2011
Rated 1.0 out of 5.0 by Misting nozzles clogged despite using filter Applied this filter suppllied with a new high pressure (1000 psi) misting system. Mist was great for the first two days, then misters began to clog with calcium traces along their edges. July 16, 2013
