HEALTHY SAFE WATER: SpiroPure polyphosphate filters utilize a slow dissolving media made from clear, food-grade polyphosphate beads to assist in minimizing common water quality problems such as discoloration, staining, scale, corrosion, and bad taste and odor LOW MAINTENANCE FILTRATION: A salt-free scale inhibitor conditions your water to prevent hardwater buildup and corrosion without the use of messy salts, electricity, or regeneration cycles. Simply replace the filter cartridge every 6-12 months INHIBIT SCALE AND CORROSION: Polyphosphate filters “sequester” problematic minerals such as calcium and magnesium (responsible for scale and hardwater) and iron and manganese (responsible for rust, discoloration, and staining) by surrounding them in a coating that prevents the minerals from sticking and causing unwanted buildup and corrosion on plumbing pipes, appliances, and fixtures EFFICIENT AND ECONOMICAL: Along with lower maintenance costs than traditional water filters, polyphosphate filters are the more water efficient choice, resulting in zero wastewater. Traditional water softeners release brine wastewater after each regeneration cycle, rinsing the resin beads of contaminants BETTER TASTE AND ODOR: Unlike salt-based water softeners, polyphosphate cartridges adapt to changes in water quality without changing the chemistry of the water. As a result, the odorless phosphates won’t add any flavor or odors to water. In fact, you may notice an improvement in taste and smell as certain metals are treated SpiroPure Polyphosphate Anti-Scale Water Filters employ the use of food-grade, clear polyphosphate beads to improve water quality by minimizing discoloration, staining, scale, corrosion, and bad taste and odor. The slow dissolving beads “sequester” problematic minerals like iron, magnesium, calcium, and manganese by surrounding them in a coating. This coating prevents the minerals from sticking to surfaces to cause hardwater buildup or rust and corrosion. 10x2.5 hard water filters preserve healthy minerals like calcium and magnesium in water while protecting the shower, bathroom sink, bathtub, kitchen dishwasher, washing machine, and more from scale deposits. Because our anti-scale filter cartridges are salt free and the polyphosphates are odorless, the taste and smell of water is preserved. Economical polyphosphate filters require less maintenance than traditional water softener systems. No salt or electricity is required; simply replace the water filter cartridge. These filters also are more water efficient than traditional water softener systems, with zero wastewater.
