This Essential Certified Series whole home filtration system by Tier1 is ideal for smaller homes, condominiums, and offices. The Carbon and KDF filtration system by Tier1 provides clean water to all connected outlets making maintenance a breeze and cluttered supply rooms a thing of the past. Designed with the whole home in mind, the system reduces sediment, herbicides, pesticides, and chlorine taste and odor. The carbon and KDF media reduce a vast amount of microorganisms, small alloy particles, and even turn harmful contaminants into harmless components through electro-chemical reactions.

The Tier1 5-Stage Reverse Osmosis System is the complete package, using 5 stages to deliver up to 50 gallons of filtered water per day. The 5 stages include a first stage sediment filter, to remove particular contaminants, followed by a carbon filter for bad taste and odor, and a third stage sediment filter to remove any remaining contaminants, prolonging the health and performance of your system. The 4th stage is our Tier1 RO membrane which removes 99% of all Total Dissolved Solids, and lastly an inline carbon block filter to polish the water. Once processed, the water is transferred to an automatic shutoff valve equipped storage tank where it waits for you to turn on the tap!
