2. Reverse Osmosis (RO) Filters
Some modern refrigerators utilize reverse osmosis systems, which are more complex and typically found in higher-end models.
How do they work?
– Semi-Permeable Membrane: Water is pushed through a membrane that only allows certain molecules, like water, to pass through while blocking larger impurities and contaminants.
– Dual Filtration: This may also include a pre-filter to remove larger sediments before water reaches the RO membrane.
How A Refrigerator Water Filter Works
Understanding the operational mechanics of a refrigerator water filter involves breaking down the filtration process into distinct steps.
Step 1: Water Intake
The filtration process begins when you access your refrigerator’s water dispenser or ice maker. When you press the lever, cold water flows from the household water supply into the refrigerator’s water line.
Step 2: Flow through the Filter
Once the water enters the refrigerator, it encounters the water filter. Here, the incoming water moves through specific filtration components based on the filter type:
- For activated carbon filters, water is drawn through the carbon block, where harmful substances are captured and eliminated.
- For reverse osmosis systems, the water is forced through the semi-permeable membrane, effectively separating contaminants from the clean water.
Step 3: Filtering Process
As the water flows through the filter:
- Impurities, sediments, and chemicals adhere to the filter medium (like activated carbon) or are blocked by the RO membrane.
- Water molecules pass through, emerging clean and purified.
Step 4: Clean Water Output
Finally, the filtered water is routed to your refrigerator’s dispenser or to the ice-making component, allowing you to enjoy fresh, clean water or ice at any time.
