In this comprehensive guide, we delve into the details of whether the water dispensed from your refrigerator is filtered, how the filtration process works, and the benefits of consuming filtered water.
How Refrigerator Water Dispensers Work
Refrigerators with built-in water dispensers often also come equipped with ice makers. These innovations not only provide convenience but also ensure you have access to cold water and ice in one simple appliance. But how does this system function when it comes to water filtration?
The Water Supply Connection
Most refrigerator water dispensers are connected directly to your home’s plumbing system. The water is typically sourced from your municipal water supply or a well. Before reaching the water dispenser, the water passes through a filtration system designed to improve quality and taste.
The Filtration System
Not all refrigerators filter water. However, many modern refrigerators come equipped with built-in water filtration systems, often referred to as “water filter cartridges.” These cartridges are designed to remove contaminants and improve the taste of the water.
Here’s how the filtration process generally works:
Pre-filtration: Water first enters the filter cartridge, where a mechanical filtration process may occur. This cuts down larger particles like rust, sediments, and dirt.
Activated Carbon Filtration: The water then passes through activated carbon, which adsorbs chlorine, odor, and various other impurities, thereby enhancing the water’s taste and smell.
Post-filtration: After passing through carbon, the water is further filtered through a micron filter that ensures even the smallest contaminants are removed.
The Importance of Water Filtration
Water filtration is essential for several reasons, as it can significantly affect your health and your home’s plumbing system.
Health Benefits
Clean water is vital for your health. Some potential contaminants that can be found in unfiltered water include:
