Why Does My Reverse Osmosis (RO) Water Have Air Bubbles After Installation or Filter Change?

What Are Air Bubbles in RO Water?

Air bubbles in your RO water occur due to trapped air or dissolved air being released during the filtration process. When you install or change the filters in your system, the water pressure changes, and this can cause small pockets of air that were previously dissolved in the water to form visible bubbles.

Why Does This Happen After Installation or Filter Changes?

1. Disruption of the System: When a new RO system is installed or filters are replaced, air is introduced into the system as it fills with water. The air that was trapped in the filter housing or in the tubes may escape during operation.

2. Water Pressure Adjustment: After filter installation or a change, the water pressure in the system can vary. If there was air dissolved in the water, it might come out of solution (just like opening a bottle of soda), causing bubbles to form.

3. Fresh Filters and Membranes: New filters may not be fully saturated with water initially. As the system starts running, the water fills the filters, pushing air out. This can result in some air bubbles, particularly in the first few gallons of water you use after installation or a filter change.

Is It Harmful?

Absolutely not! The presence of air bubbles in your water is entirely safe and does not affect its quality. RO water is purified and filtered thoroughly, and the air bubbles are simply a side effect of the system filling with water or adjusting to its new filters.

How Long Will the Air Bubbles Last?

The air bubbles should dissipate quickly. Once the system stabilizes and fully fills the filters, you’ll notice the bubbles will gradually decrease, typically within a day or two. If you continue to see bubbles after this period, it may be worth checking the system for air leaks or contacting your service provider, but in most cases, it’s nothing to worry about.

Tips to Reduce Bubbles in Your RO Water:

• Flush the System: After installation or filter replacement, it's recommended to run several gallons of water through the RO system. This will help expel any trapped air and ensure proper operation.

• Check for Leaks: If you're experiencing excessive bubbling beyond the initial period, double-check your RO system’s fittings and connections to make sure everything is sealed tightly.

• Wait for Stabilization: Give your RO system some time to stabilize after installation or filter change. The air bubbles will eventually disappear as the system settles.

Conclusion:

Air bubbles in your RO water are a completely normal and harmless occurrence after installing or replacing filters. It’s simply a natural result of the water system adjusting, and it should resolve itself shortly. If you're ever uncertain, always feel free to consult the manufacturer’s instructions or contact customer support to ensure everything is functioning properly.
