Patented Anti-Backwash, Dual-Valve Design
Solution can only flow into the sinuses, not back into the bottle
Prevents negative pressure from crushing the bottle, allowing solution to continually flow into the sinuses for efficient cleaning.
Two valves, not a single air valve, must work together to truly avoid backwash.
Working in tandem, the two valves:
- Prevent backwash
- Allow solution to continually flow for more effective, thorough and gentle cleansing
- Allow an easy maintenance; without back-wash caused contamination, a quick rinse is all that’s needed (“backwash bottles” require many steps of cleaning)
