Based on the provided information, you can determine when to change the filters on your reverse osmosis system by measuring the total dissolved solids (TDS) in the filtered water. If the TDS reading starts to rise significantly, it's time to change your filters. The video shows a TDS reading of 327 parts per million, but doesn't specify what reading would indicate it is time to change the filters.
However, the video snippet doesn't provide exact guidance on specific timeframes or TDS levels. Therefore, a complete answer requires more information. Generally, here's how you determine when to change the filters:
General Guidelines for Reverse Osmosis Filter Changes
While the video shows how to measure the TDS, here's a more complete explanation of filter replacement schedules:
- Sediment Filter: Replace every 6-12 months. This filter removes particulate matter like dirt, sand, and rust, protecting the subsequent filters.
- Carbon Filters (Pre- and Post-): Replace every 6-12 months. These filters remove chlorine, chloramine, and other organic contaminants that affect taste and odor, as well as protect the RO membrane.
- Reverse Osmosis Membrane: Replace every 2-5 years. The RO membrane is the heart of the system, removing a vast majority of dissolved solids. A noticeable increase in TDS or a significant decrease in water production indicates it's time to replace it.
- TDS Meter Readings: Regularly test your RO water with a TDS meter. A reading above a certain threshold (consult your system's manual, but generally above 50 ppm may indicate a need for replacement soon) or a significant increase from a previous reading suggests the membrane is failing.
- Water Taste and Odor: If you notice unpleasant tastes or odors in your filtered water, even after replacing the carbon filters, the RO membrane might need replacement.
- Water Production Rate: A significant decrease in the amount of filtered water produced can indicate clogged filters or a failing membrane.
In summary: Regular monitoring of TDS levels and adherence to recommended replacement schedules are essential for maintaining the performance of your reverse osmosis system. Check your RO system's manual for specific TDS targets and replacement schedules, as these vary based on the model and water quality.
