what is the best water softener

The first thing that you need to do is get a test kit  so that you can determine how much hardness and iron your water contains. This will help you to figure out what type of water softener will best suit your needs. Water softeners can remove a limited amount of dissolved iron from your water supply. Aqua-Pure NWS100 NWS Series Water Softener System from Faucet Depot is one of the best  water softeners that you can buy.
Features:

• High capacity, long life ion exchange resin
• Motorized piston control valve
• Rust purge turbulator
• Safety brine valve
• Salt support shelf
• Timer-initiated regeneration control
• Decorative insulation jacket
  

This water softener will prevent the reduction of water pressure which is caused by the scales in the pipes. Kenmore 370 Series Water Softener is another good water softener that you can find at Sears.
