SCULE-0400 Semi-Commercial Alkaline Filter System

The APEX SCULE-0400 filtration system does more than simply filter water. The SCULE-0400 uses four stages of water filtration to create pure 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 best part is the water does not taste bitter or chalky! The APEX SCULE-0400 makes refreshing water the whole family will enjoy.

The APEX SCULE-0400 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 and ultra low energy membranes are available from APEX Water Filters.

  1. Clarence

    Our bore well water is quite rusty to be honest. Simple purifiers did not work much. But this one is working great and also made the rusty color go away

  2. Melida

    My friend was recently diagnosed with cancer and the source was his contaminated water source coming from industries. So , I bought this just because it has carcinogen removing feature

  3. Ramirez
