Clinical Outcomes & Moisture Data
102,133 readings with detected moisture — a practical clinical framework showing that moisture is invisible, universal, and always worth removing.
Based on 102,133 Redux Pro readings with detected moisture (≥0.1 µL), November 2019 – July 2022. 532 machines at 257 clinical partners (451 locations). Improvement rates based on 33,673 readings with recorded user outcome.
The Invisible Problem
The Redux Pro workflow captures what hearing aid users experience before and after moisture removal — revealing what they didn’t know they were missing.
“Even when hearing aid users said ‘it’s working fine,’ nearly 4 out of 5 heard improvement after treatment. They didn’t know moisture was affecting their hearing.”
User Assessment
Audiologist asks: “How is your hearing aid performing?”
Condition reported by user:
Dead • Weak • Normal
Moisture Removed
Vacuum drying with ±0.1 µL precision
User Feedback
“Does your hearing aid sound better?”
User reports improvement:
Louder • More Crisp • Clearer
“Normal” — Working Fine
Hearing aid user reported their device was amplifying properly
“Weak” — Underperforming
Hearing aid user reported their device wasn’t loud enough
“Dead” — No Sound
Hearing aid completely stopped working
“Not Recorded”
The hearing care professional did not obtain a check-in pre-assessment, however the post treatment check-out assessment was still recorded
The key insight: Moisture degrades hearing aid performance even when hearing aid users don’t perceive a problem. Nearly 80% of “Normal” devices sounded better after treatment.
Three-Zone Clinical Framework
Every reading with detected moisture (≥0.1 µL) falls into one of three clinically actionable zones. Click each zone to learn more.
Every zone means moisture was present and removed. Blue is not “all clear” — it confirms that even routine moisture accumulation is measurable and that the device benefited from professional treatment.
Routine Moisture — Device Benefited From Treatment
The most common result. Measurable moisture was present and successfully removed. Even at this level, hearing aid users consistently report clearer sound after treatment. Blue does not mean “all clear” — it means daily moisture accumulation is within the routine range.
Moderate Moisture — Warrants Clinical Attention
Moisture exposure beyond routine daily accumulation. May reflect environmental factors (high humidity, exercise), behavioral patterns (inconsistent drying), or a specific moisture event. At this level, moisture is actively degrading device performance.
Significant Moisture — May Indicate Water Damage
Substantial moisture presence. For context, completely inoperable (“Dead”) devices averaged 4.33 µL. Readings at this level suggest a significant water exposure event or prolonged accumulation without treatment. Devices may have experienced component stress.
The difference between zones is the urgency of the conversation, not whether one is needed. Every reading ≥0.1 µL means moisture was present and removed — every treatment is a counseling opportunity.
Success Rate by Moisture Volume
Higher moisture levels correlate with higher perceived improvement — because the performance impact was greater before treatment.
Why higher moisture = higher perceived improvement
This pattern is expected: devices with more moisture removed are more likely to show perceptible improvement because the performance impact was greater before treatment. A 75.7% improvement rate in the Blue Zone does not mean treatment was less effective — it means there was less perceptible degradation to reverse. The moisture was still present and still removed. Based on 102,133 readings across all zones.
