Quick Answer
The expected lifespan of reverse osmosis (RO) filters is typically around 6-12 months, depending on usage and quality of the filter. Proper maintenance can extend its lifespan. Regular replacement is necessary for optimal performance.
Filter Replacement Schedule
A general guideline is to replace the pre-filter every 6-9 months and the RO membrane every 9-12 months. However, this may vary depending on water quality, usage, and filter quality. For example, a household with 4-6 people may require more frequent replacements than a single-person household. It’s essential to follow the manufacturer’s recommended replacement schedule and monitor the filter’s performance to determine the optimal replacement interval.
Maintenance and Performance Factors
Factors such as water hardness, pH levels, and sediment content can significantly impact the lifespan of RO filters. High levels of minerals like calcium and magnesium can reduce the filter’s lifespan, while high pH levels can cause the membrane to degrade faster. Regular maintenance tasks like cleaning the filter housing and checking for leaks can also help extend the lifespan of the filter.
