Give your pool an additional layer of protection and sanitation beyond the capabilities of chlorine or salt-based chlorine generators. Water circulates through the Ultra UV2 chamber and the UV-C lamp immediately inactivates 99.9% of micro-organisms such as crypto, giardia and algae which are resistant to chlorine. This provides a cleaner, clearer swimming environment with zero harmful by-products. Plus, dramatically reduce the amount of chlorine needed to maintain an adequate level of residual sanitizer (a minimum residual level of chlorine or bromine should be maintained at all times). Paramount’s eco-friendly, Ultra UV2 – Ultraviolet pool system for clean, healthy water in new or existing pools.
