How Whole House Water Filters Work

Whole house water filter systems are an integral part of maintaining a healthy home environment. These systems typically function in four essential stages:

Pre-filtration: This stage involves removing large particles and impurities from the water, which helps prevent clogging in later stages.

Chlorine Removal: The second stage is crucial for removing chlorine and similar substances, improving the water’s appearance and smell.

Activated Charcoal Filtration: This stage catches impurities not captured by the first two filters, significantly improving the water’s taste.

Final Filtration: The last stage captures any remaining contaminants. Here, UV kits can be used to eliminate the majority of impurities, ensuring the water’s purity.


6 Reasons for Using a Whole House Water Filter System

  1. Heavy metals like lead, mercury, and arsenic, common in the Earth’s crust, can infiltrate tap water. Whole house filters effectively remove these harmful elements.
  2. Tap water can contain up to 2100 known toxins. Filtered water reduces the load on your kidneys, aiding in detoxification and promoting optimal health.
  3. Clean water is essential for a strong immune system, protecting against viruses, pathogens, and bacteria. It’s particularly crucial for the healthy development of children.
  4. Filtered water reduces the risk of birth defects like spina bifida in newborns and is safer for preparing baby formula.
  5. Regular consumption of clean water can alleviate frequent headaches and constipation. Since the brain is 73 percent water, clean water is essential for its proper functioning.
  6. Washing and cooking food with filtered water ensures that no waterborne contaminants affect the taste or healthiness of your meals.


Choosing the Right Whole House Water Filter

Testing Your Water: Before selecting a filter, test your water to identify specific contaminants.

Filter Effectiveness: Choose a filter that targets the contaminants present in your water supply.

NSF Certification: Look for filters certified by the National Sanitation Foundation (NSF), but remember that some high-quality filters from smaller companies may not have NSF certification due to the cost.

Filter Lifespan: Consider how often you’re willing to change the filter. Options range from annual to multi-year lifespans.

Installation and Maintenance: Professional installation is recommended for proper setup. Regular maintenance, including replacing pre-filters and carbon filters every six months to three years based on usage, and disinfecting the system, is crucial for optimal performance. Water softeners in the system may also need periodic replacement.
