Water Softeners, Water Filtration, & Reverse Osmosis Water Systems

There are many types of water filtration systems & solutions available; however, understanding the different filtration solutions can be daunting for any homeowner to take on. We recommend a water softener with a reverse osmosis system for the majority of homes. But what’s the difference? A reverse osmosis system (or RO system) filters up to 98% of all contaminants from your drinking water giving you high quality purified drinking water versus a water softener that removes all hard minerals from your water. These systems together provide your family the best, highest quality drinking water and hard water protection for your entire home.


High quality water is not limited to houses, we have water filtration systems and bottle-free cooler solutions for commercial applications, businesses, condos, mobile homes, almost anywhere! Depending on the situation we have different sized water filters to fit smaller under sink or whole house applications to filter out unwanted minerals and impurities. Everyone deserves better water quality!


Rayne of San Diego is proud to be a local fixture in the San Diego and the outlying neighborhoods. We’ve been serving our neighbors since 1955 with clean, great tasting water from our water filtration systems.
