Under-sink filters clean the water you drink. Whole house systems clean every gallon that enters your home — showers, laundry, appliances, ice makers, and all taps. If you're concerned about chlorine exposure through skin and inhalation during showering, a whole house system addresses what a drinking water filter can't.
Hot water opens pores. Chlorine absorption through skin and inhalation during showers can exceed what you'd drink in a day.
Kitchen, bathrooms, laundry — every water outlet in your home runs through the same filter media.
Sediment and scale damage water heaters, dishwashers, and ice makers. Whole house filtration extends appliance lifespan.
Chlorinated water degrades fabrics faster and fades colors. Filtered water is gentler on clothes and preserves elasticity.
