The APWC-AWS100M is a 30,000 grain electronic metered water softener. This is the best choice if you face the nuisance of hard water on a regular basis. This APWC-AWS100M softener removes scale-causing minerals that are commonly found in hard water areas. This includes hardness caused by minerals and salts dissolved in water. The APWC-AWS100M is a smart operator. It has appreciable water heating efficiency and prevents the loss of water pressure that is often the result of large-scale scaling in water pipes. It uses a fully automatic operation, monitoring water usage and regenerates only when necessary. This minimizes the use of electrical energy and cuts down on wastage of water. The APWC-AWS100M scrubs the ion exchange resin during backwash. This helps to maintain maximum resin and system performance. It uses a fully-automatic, highly-efficient design. It is made from FDA-compliant, CFR-21 materials.
