Unlike traditional water softening options, our Salt-Free Conditioner helps you reduce scale build-up on appliances, without monthly upkeep or the addition of salt pellets. The built-in pre-filter reduces particulates; while the Conditioner works to minimize the scale-producing minerals often found in municipal water supplies and plumbing lines. Note: This product is meant to be used on a standalone basis and includes a pre-filter. Click here if you are looking for a Water Conditioner to add on to the HomeWater Whole Home Filter.
