The APWC-AWS300M is a residential water softener system. It is 90,000 grain electronic metered water softener. The system removes minerals and salts from hard water that can reduce the overall quality of water and its taste. This also helps to optimize the water heater's efficiency and prevents loss of water pressure caused by scaling in the pipes. APWC-AWS300M has a fully-automatic operation. It also monitors usage of water and regenerates only when necessary. This helps in minimizing use of electrical energy, wastage of water, and concentration of salts in water. The softener can resolve more hard water issues like soap curding, spotting on glasses, and formation of rings on tubs and sinks. It is made from FDA CFR-21 compliant materials, setting a benchmark in the niche of water softening. The softener is now approved by the Food and Drug Administration.
