What Are Whole Home Water Filtration Systems?

Whole home water filtration systems, often referred to as point-of-entry systems, are designed to treat all the water entering a household, ensuring that every water source inside the home, from the kitchen faucet to the shower, provides clean, safe, and high-quality water. These systems can be categorized based on the source of water they treat: city water filtration systems and well water filtration systems.

City Water Filtration Systems

City water, supplied by local municipalities, typically undergoes a primary level of treatment before reaching your home. However, this water can still contain various contaminants, such as chlorine, lead, and other chemicals that can affect water taste, odor, and safety. Whole home water filtration systems for city water are designed to remove these residual contaminants, providing an additional layer of purification to ensure the water’s safety and improve its quality for drinking, cooking, and bathing.

Well Water Filtration Systems

Well water comes directly from the ground and, while rich in minerals, can contain sediments, bacteria, and other contaminants that may pose health risks or cause water hardness. Whole home water filtration systems for well water are specialized to tackle these unique challenges, often incorporating sediment filtration, UV purification, and water softening technologies to make the water safe and pleasant to use.

Benefits of Water Treatment Systems

Investing in a home water filtration system offers many benefits. As a homeowner, they can ease your concerns about water safety, health, convenience, and the overall quality of life. Here are several reasons why a homeowner might consider installing a water treatment system:

  • Enhanced Water Quality: Removes contaminants, improving the taste, odor, and clarity of water.
  • Health Benefits: Reduces the risk of exposure to harmful contaminants and bacteria.
  • Appliance and Plumbing Lifespan: By removing minerals that cause scale buildup, these systems extend the life of plumbing fixtures and water-using appliances like washing machines, dishwashers, water heaters and pipes.
  • Eco-friendly: Reduces dependency on bottled water, minimizing plastic waste.

Types of Home Water Treatment Systems

There are a few different types of home water treatment systems available today, each serving a different purpose to solve water quality issues. Below is an overview of the primary types of water treatment systems available for homes.

Filtration Systems

Home water filtration systems are designed to treat all the water coming into the home, removing contaminants like sediment, chlorine, and other organic or inorganic substances. These filtration systems are typically installed at the point where the main water line enters the house, and aim at improving water quality for drinking, cooking, and bathing. Filtration systems can also protect the lifespan of appliances and plumbing by reducing mineral buildup.

The cost of a whole home water filtration system varies widely based on the type of system, the specific water concerns it addresses, and the size of the home. On average, these systems can range from $1,000 to $4,000, excluding installation fees. High-end models with advanced features, such as UV purification, can cost more.

Water Softener Systems

Water softener systems are specifically designed to address water hardness, a common issue caused by high levels of calcium and magnesium in the water. These systems work through a process known as ion exchange, replacing hard minerals with sodium or potassium ions. This not only prevents scale buildup but also enhances the efficiency of soap and detergents, resulting in softer skin and cleaner, brighter clothes.

The cost of a water softener system largely depends on the system’s capacity and whether it uses salt-based or salt-free technology. Prices typically range from $500 to $2,500. Installation costs can add $200 to $500 or more to the total expense, depending on the complexity of the system and the layout of the home.

Reverse Osmosis Systems

Reverse osmosis (RO) systems offer a high level of purification by forcing water through a semipermeable membrane, effectively removing up to 99% of waterborne contaminants, including salts, bacteria, fluoride, lead, viruses, and chemicals. These systems are typically installed under the kitchen sink to treat water at a single point of use, and are most commonly used to treat drinking and cooking water. For this reason, most homeowners use RO systems in conjunction with a whole home water filtration system.

Reverse osmosis systems that are used for point-of-use water purification typically cost between $150 and $1,500. Professional installation costs can vary from $100 to $500, depending on the complexity and whether additional faucets or plumbing modifications are required.

Ultraviolet (UV) Systems 

Ultraviolet (UV) purification systems specifically target the deactivation of bacteria, viruses, and other pathogens by exposing them to UV light, which damages their DNA and renders them harmless. These systems are often installed as part of a larger home water treatment system, and typically used at the point where treated water enters the home or at the point of use. 

UV filtration systems are known for providing a chemical-free way to disinfect water, ensuring it is safe from microbiological contaminants without altering the taste or odor of the water. It’s helpful to know that UV systems do not filter out chemicals or minerals, but rather ensure the water is biologically safe to drink.

UV water purification systems are generally priced between $200 and $1,500. Installation might add $100 to $300 to the overall cost.

Low-Cost Water Filtration System Options

If you are concerned about the price tag that comes with installing a whole house water filtration system, there are low-cost water filtration systems offer an affordable and easy way to enhance your drinking water’s taste, smell, and safety. Suitable for any household, they’re a smart choice whether you’re dealing with known water issues or just want extra peace of mind. These systems are a great starting point for healthier living and can lead to more advanced water treatment solutions later on.

Sink Water Filtration Systems

Sink water filtration systems, including both under-sink and countertop variants, provide a practical solution for accessing purified water straight from your kitchen faucet at a cost ranging from $50 to $150. These systems excel in enhancing water quality for cooking and drinking by eliminating dangerous contaminants such as lead, chlorine, and pesticides. 

Besides their health benefits, they boast an easy DIY installation process. Under-sink models, which tend to be more discreet, and countertop models, which may suit those with more space or simpler installation needs, cater to different preferences and kitchen layouts. Their affordability and straightforward setup, combined with the significant improvement they offer in water taste and safety, make them a valuable addition to any home seeking a convenient and effective water purification solution.

Showerhead Water Filters

Shower head water filters, priced around $20 to $50, easily attach to your existing shower head, instantly improving water quality to protect skin and hair from chlorine and other harsh chemicals. They also reduce the risk of respiratory problems linked to volatile organic compounds in hot showers. Simple to install, these filters not only offer health benefits but also enhance your shower experience, making water feel softer and more pleasant for personal care.

Hiring a Professional Water Treatment System Installer

Working with a professional water treatment system installer is crucial for several reasons, ensuring that the system functions effectively and provides the maximum benefit. Here are the key reasons to hire a professional:
