The Modern Filtration Essential 4-Stage Municipal Water Filtration System is loaded with features the higher-end systems have, yet still modestly priced. You’ll enjoy spring-quality, alkaline drinking water from every faucet in your home – with no maintenance at all.

The Essential water filtration system removes hazardous contaminants such as chlorine, trihalomethanes (THMs), Volatile Organic Chemicals (VOCs), heavy metals, herbicides, pesticides, and numerous pharmaceutical residuals.

The Bi-Polarity Anti-Scale Ionizer prevents hard water scale build-up without using synthetic materials like polyphosphates, which are commonly found in many salt-free, multi-tank systems. The ionizer reduces hard water scale inside your pipes, on plumbing fixtures and increases the life of costly appliances. Ionized water also provides healthy pH-balanced drinking water.

You can choose the appropriate size for either up to three or five bathrooms, too.

If you’re searching for an economical, superior-grade water filtration system that delivers pure, alkaline water, the Modern Filtration Essential 4-Stage is for you.

4 Stages of Water Filtration



KDF55 removes heavy metals, chlorine and volatile organic chemicals (VOCs). It also raises pH*, reduces bacterial growth, controls hard water scale and algae growth by killing waterborne bacteria, parasites, cysts and viruses.


Coconut Shell Carbon

Our carbon is certified by the National Sanitation Foundation (NSF). It is a highly adsorbent material used to remove water contaminants. Activated carbon removes unpleasant tastes, odors, color, chlorine and volatile organic chemicals (VOCs). Activated carbon is approved by the Environmental Protection Agency (EPA) to remove a variety of dangerous and possibly carcinogenic chemicals in drinking water. This includes PFAs (“Forever Chemicals”), pesticides, herbicides and trihalomethanes (THM), which are a group of suspected carcinogens.


Quartz Mineral Stone

Water passes through a bed of quartz mineral stone removing suspended solids and sedimentation. It also boosts water distribution and efficiency.


Bi-Polarity Anti-Scale Ionizer

This reduces hard water scale formation considerably and extends the life of expensive appliances and plumbing fixtures. It also provides better lathering of soaps and detergents, reduces water spotting and is environmentally friendly.

*pH levels vary based on geographic region and contaminants removed from the water supply.
