Yes, I've used one. The cost is about £30 sterling. They are maintenance free. They are claimed to last forever, as long as the magnetic field is present. They are not as good as a traditional water softener. I have found that they don't totally soften the water (they don't remove any chemicals). They work (I seem to remember) by aligning all the ions in the water the same way which some how stops the hard water chemicals from sticking to anything. If you need to remove the hard water chemicals use a traditional water softener (Resin type) ===== Original Message from [log in to unmask] (TechNet E-Mail Forum.) at 15/06/99 20:10 >Has anybody heard of, or used a device that is basically a magnetic type >filter (so I'm told) that is used in line to soften water. > >If so I would appreciate any info: > - approx cost compared to typical water softner > - maintenance > - life expectancy > - efficiency > >Ted > >################################################################ >TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c >################################################################ >To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: >To subscribe: SUBSCRIBE TechNet <your full name> >To unsubscribe: SIGNOFF TechNet >################################################################ >Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information. >For technical support contact Hugo Scaramuzza at [log in to unmask] or 847-509-9700 ext.312 >################################################################ Mark Austin (Process Engineer) ACW Technology Limited Hylton Road Petersfield GU32 3XX ENGLAND TEL - +44 (0) 1730 300000 FAX - +44 (0) 1730 266045 Email - [log in to unmask] ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
