Reverse osmosis (RO) water filtration systems provide your home with clean, great-tasting water by removing impurities and contaminants.
To keep your RO system functioning effectively, it's essential to replace the filters regularly. In this comprehensive guide, we'll show you how to change a reverse osmosis filter for several popular brands and provide general instructions that apply to most systems.
If you're unsure or need professional help, WaterSmart Systems is here to assist with all your reverse osmosis filter needs.
How to Change Reverse Osmosis Filter
1. Why Change Your Reverse Osmosis Filter?
Regularly replacing the filters in your reverse osmosis system is essential for maintaining both the quality of your water and the efficiency of the system itself.
Over time, the filters become clogged with debris, sediment, and other impurities, which can lead to a variety of issues if not addressed. Here’s why timely replacement is so important:
1. Ensures Clean and Safe Drinking Water
Reverse osmosis systems are designed to remove harmful contaminants such as chlorine, lead, arsenic, and other impurities. When filters become saturated, they lose their ability to effectively remove these substances, compromising the safety and taste of your drinking water. Replacing the filters ensures that your water remains pure and free from harmful pollutants.
2. Maintains Optimal System Performance
A clogged or overused filter forces the system to work harder, which can reduce water flow and put unnecessary strain on the unit. Over time, this can lead to increased wear and tear, higher energy consumption, and even system failure. Regular filter changes help the system operate efficiently and prolong its lifespan.
3. Prevents Bacterial Growth
Filters that aren’t replaced on time can become a breeding ground for bacteria and other microorganisms. These contaminants can re-enter your water supply, negating the purpose of having a reverse osmosis system. Routine maintenance keeps your system hygienic and safe.
4. Improves Water Taste and Odor
Old filters may allow unpleasant tastes or odours to seep into your water. This is particularly noticeable when carbon filters, which are responsible for removing chlorine and improving taste, are overdue for replacement. Fresh filters ensure that your water remains crisp and refreshing.
5. Protects the RO Membrane
The pre-filters in your system, such as sediment and carbon filters, play a crucial role in protecting the RO membrane by trapping larger particles and chlorine before they reach it. Neglecting to replace these filters can lead to damage or clogging of the RO membrane, which is expensive to replace. Keeping the pre-filters in good condition helps avoid costly repairs.

2. How Often Should You Change Reverse Osmosis Filter?
Filter replacement schedules vary based on usage and water quality. As a general rule:
Sediment Filter: Every 6–12 months
Carbon Pre-Filters: Every 6–12 months
RO Membrane: Every 2–3 years
Post-Carbon Filter: Every 12 months
How These Filters Work Together
The sediment filter and carbon pre-filters prepare the water by removing larger particles and chemicals that could harm the RO membrane.
The RO membrane performs the heavy lifting by removing the tiniest impurities, leaving you with purified water.
The post-carbon filter finishes the job, ensuring the water tastes and smells its best.
Regular maintenance of these filters keeps your system working efficiently and ensures your family always has access to high-quality drinking water.
