What is a Reverse Osmosis drinking water system?

A reverse osmosis drinking water system treats water at the point of use, typically under the kitchen sink. It uses a high-precision RO membrane and multiple filtration stages to reduce dissolved contaminants that are difficult to remove with standard filters.

Depending on the model, additional stages may restore essential minerals, improve taste, and allow control over water alkalinity. These systems are designed specifically for drinking and cooking.

How Reverse Osmosis Purifies Drinking Water

Reverse osmosis systems purify water through multiple stages:

  • Pre-filters reduce sediment and chlorine
  • The RO membrane removes dissolved salts and many dissolved contaminants
  • Post-filtration improves taste and clarity
  • Advanced models restore minerals and adjust pH

Together, these processes deliver clean, balanced drinking water directly from your tap.

Is a Reverse Osmosis System Right for Your Home?

You may benefit from a reverse osmosis drinking water system if:

  • Your primary concern is drinking and cooking water quality
  • You want advanced reduction of PFAS, heavy metals, or dissolved contaminants
  • You prefer purified water with optional mineral restoration
  • You want a dedicated drinking water faucet at the kitchen sink
  • You are looking to reduce bottled water use

Because drinking water needs vary by household and water source, a professional water test helps determine whether reverse osmosis is the right solution for your home.

What Contaminants Can Reverse Osmosis Reduce?

Reverse osmosis drinking water systems are effective at reducing:

  • PFAS ("forever chemicals")
  • Lead, arsenic, and other heavy metals
  • Chlorine and chemical residues
  • Total dissolved solids (TDS)
  • Certain dissolved inorganic salts and compounds
  • Unpleasant taste and odour

Advanced filtration stages further enhance water quality after purification.

Advanced Features Available in Select Kent Reverse Osmosis Systems

Some Kent reverse osmosis models include advanced post-filtration stages designed to enhance water quality beyond basic purification. Depending on the system selected, features may include:

  • Mineral restoration to improve taste and maintain balanced drinking water
  • Alkaline pH adjustment, allowing homeowners to choose a preferred pH level
  • Hydrogen-enriched water, generated through specialized post-filtration technology
  • Reduced oxidation-reduction potential (ORP), often associated with fresher-tasting water
  • Bacterial reduction, when combined with UV or advanced filtration stages
  • Reduction of organic impurities that can affect taste and odour

Not all features are included in every system. A water test and consultation help determine which options are appropriate for your home and drinking water needs.

Reverse Osmosis vs Whole Home Filtration

Reverse osmosis and whole home filtration serve different purposes and are often used together, depending on how water is used in the home.

Reverse Osmosis Systems

Reverse osmosis systems are designed specifically for drinking and cooking. Installed under the kitchen sink, they provide high-level purification by reducing dissolved contaminants such as PFAS, heavy metals and total dissolved solids.

Whole Home Water Filtration Systems

Whole home filtration systems treat water at the main entry point, improving overall water quality throughout the house. These systems enhance water for bathing, laundry, and cleaning but are not intended to provide the same level of purification required for drinking water.

Many homeowners choose to combine both solutions using whole home filtration for everyday household water and reverse osmosis for premium drinking water quality.
