Your Rainbow’s Performance Depends on the Right Foundation.

The SRX Water Basin is where the magic happens. It’s where airborne dust, allergens, and particles get pulled in and locked down by water — so they can’t fly back into your home. This official Rexair part is designed to work in perfect harmony with your Rainbow SRX system, ensuring maximum filtration, proper airflow, and a tight, leak-free seal.

Crafted from durable, impact-resistant material, the SRX basin is easy to remove, rinse, and reattach — making it simple to keep your system (and your home) running at its best.

✅ Original factory-made basin for the Rainbow SRX
✅ Engineered to support optimal airflow and suction
✅ Crystal-clear design lets you monitor dust and water level
✅ Built tough to resist cracking, staining, or odors
✅ Easy to clean, easy to click into place

A generic basin might not fit perfectly — leading to leaks, poor airflow, and dust escaping.
