Choosing the Best Water Filtration System: Under-Sink vs. Whole House Solutions

Clean water is essential for every home, whether for drinking, cooking, bathing, or for general household use. If you're considering a water filter system, you may be wondering whether an under sink water filter or a whole house water filter is the best choice. While under-sink filters provide localized purification, a whole house water filtration system offers comprehensive protection for your entire home, ensuring every tap and appliance receives high-quality, filtered water.

Why Filter Tap Water in Australia?

Many Australians wonder, "Should I filter my tap water?" While Australia has high water quality standards, contaminants such as chlorine, heavy metals, sediment, microplastics, and even PFAS (per- and polyfluoroalkyl substances) can still be present in tap water. Filtering your water ensures you get the best possible quality, taste, and safety for your household.

Common Water Contaminants in Australia

• Chlorine & Chloramines – Added to municipal water for disinfection but can cause skin irritation and unpleasant taste.

• Heavy Metals (Lead, Copper, etc.) – Leached from pipes and plumbing, potentially leading to health issues.

• Sediments & Rust – Common in older pipes, affecting water clarity and taste.

• PFAS & Microplastics – Emerging contaminants linked to health concerns.

• Fluoride – While added for dental health, some homeowners prefer to remove it.

Understanding Water Filtration Systems

A water filtration system for home removes impurities like sediment, chlorine, and chemicals, enhancing taste and reducing health risks. The two most common options are:

• Under-Sink Water Filters – Installed beneath the kitchen sink, these filters provide purified water at a single point of use.

• Whole House Water Filters – Installed at the main water line, filtering all water entering the home.

Whole House Water Filters: Comprehensive Home Protection

A whole house water filter is the superior choice for homeowners who want complete water filtration for drinking, showering, cooking, and protecting appliances from scale buildup.

Why Choose Whole House Filtration?

• Removes contaminants from every water source in your home – No more exposure to chlorine and sediments in showers, laundry, or while cooking.

• Protects your skin and hair – Filtered water reduces dryness, irritation, and exposure to chemicals like chlorine.

• Enhances the longevity of appliances – Prevents scale buildup in water heaters, washing machines, and dishwashers.

• Delivers better-tasting water everywhere – Enjoy fresh, purified water in every faucet and showerhead.

• Long-term cost savings – A whole house filtration system requires less frequent filter changes than under-sink models.

• More convenience – No need to install separate filters for drinking and shower water.

Under-Sink Water Filters: Limited Filtration for Drinking Water

An under sink water filter is a compact system designed to purify water at a single tap. While it provides filtered water for drinking and cooking, it doesn’t address contaminants in shower water or appliances.

Limitations of Under-Sink Water Filters:

• Limited filtration – Only purifies water at one tap, leaving the rest of your home exposed.

• Does not protect appliances – Hard water can still cause scale buildup in household equipment.

• Health risks in unfiltered showers – Chlorine exposure from steam and skin absorption remains a concern.

• Frequent maintenance – Smaller filters require more frequent replacements than whole house systems.

Why Whole House Filtration is the Best Investment for Your Home

1. What Do You Want to Filter?

• If you only need purified drinking water, an under sink water filter is an option.

• If you want safe, clean water throughout your home, a whole house filtration system is the best choice.

2. Budget Considerations

• A quality under sink water filter costs between $200 and $600, with annual replacement costs of $50 to $150.

• A whole house water filter system ranges from $1,000 to $5,000, depending on filtration capacity and brand.

• High-end home water filtration systems, such as Puretec Water Filters, can exceed $6,000, including installation, but provide superior long-term value.
