MR-6075 ALK Reverse Osmosis System

The APEX MR-6075 ALK filtration system does more than simply filter water. The MR-6075 ALK uses five stages of water filtration plus a final pH adjusting cartridge to create pure alkaline drinking water. The process starts by removing tiny particles like rust, silt and insect parts. This protects your family and prevents the filtration systems from clogging. Next, the water flows through two 5-micron activated carbon block cartridges. These compressed carbon block filters remove taste and odor-causing chemicals like chlorine, chloramine and rotten-egg odors. But that’s not all. Did you now that the chlorine disinfection process can create cancer-causing byproducts in the water? The good news is these carcinogens, called THMs, are removed by the carbon filters. The carbon cartridges also remove organic contaminants like herbicides, insecticides and industrial chemicals that seep into groundwater. The next step involves the reverse osmosis (RO) process. Here water is “squeezed” through a special membrane. Heavy metals, like lead and mercury, are removed while purified water passes through. The RO process also removes salts, fluoride, radon and benzene. The purified then flows through a post-filter containing granular activated carbon. This acts as a polishing filter, removing any traces of tastes, odors or gasses, for crystal clear, sparkling drinking water. The last stage conditions the purified water by gently raising the pH to an alkaline condition. Many health benefits are associated with drinking alkaline water including weight loss, antioxidant properties and reduction in bone loss (osteoporosis). The best part is the water does not taste bitter or chalky! The APEX MR-6075 ALK makes refreshing water the whole family will enjoy.

The APEX MR-6075 ALK also includes a water storage tank and designer faucet. As the filtration system makes purified water, it fills the storage tank (up to 75 gallons per day). The storage tank sends purified water to the designer faucet. Your regular sink faucet will provide unfiltered water for washing dishes. The designer faucet provides only purified water for drinking, cooking and washing vegetables.

The APEX MR-6075 ALK filtration system is pre-assembled can be installed with simple hand tools. We recommend installation by a licensed plumber to insure adherence to all local codes. Routine replacement of the filter cartridges is recommended to maintain filter performance. Replacement cartridges are available from APEX Water Filters.
