Yes. 660nm red light is a low-level, non-thermal wavelength — it does not burn, cut, or damage tissue. It has been studied extensively in clinical literature under the category of Low-Level Light Therapy (LLLT). At the energy levels used in Nolux Aero, there is no radiation risk, no UV exposure, and no known adverse effects from regular use. Your eyes are the only area to keep away from direct exposure — the nasal application keeps the light fully contained.

Sprays and antihistamines work by either shrinking blood vessels temporarily or suppressing your immune response chemically. They address the symptom, not the tissue. 660nm red light works at the cellular level — research suggests it reduces inflammatory markers in nasal mucosa and supports the tissue's own repair process. It's a different mechanism entirely, which is why people who've failed every other option often respond to this.

Most users notice a meaningful difference between day 7 and day 14 of consistent use. Some see it sooner, some take up to 3 weeks. If you use it irregularly — skipping days, doing one session instead of three — results will be slower or absent. This is not a spray. It works cumulatively, not instantly. If you complete 21 days consistently and notice zero change, use the 30-day guarantee.

Nolux Aero is a wellness device, not a medical treatment. If you have a diagnosed structural condition like a deviated septum or polyps, those are physical obstructions that red light cannot resolve. For inflammation-based congestion — triggered by allergies, pollution, dry AC air, dust — research suggests meaningful benefit. If you're unsure whether your congestion is structural or inflammatory, ask your ENT before purchasing.

No. Dependency with nasal sprays (called rhinitis medicamentosa) happens because decongestant sprays cause rebound swelling when they wear off, making congestion worse and creating a cycle. Red light therapy has no chemical mechanism and no rebound effect. You can stop using Nolux Aero at any time without withdrawal or worsening symptoms.

Compare it to what you're currently spending. A bottle of Otrivin costs ₹150–₹200 and lasts 2–3 weeks. Cetirizine strips, ENT consultations, steam machines — most people dealing with chronic congestion spend ₹400–₹800 a month on temporary fixes, every month, indefinitely. Nolux Aero is a one-time purchase. If it works — and for most users it does — it pays for itself in under 3 months. If it doesn't, the 30-day guarantee covers you completely.

The device is built for daily long-term use — the LED components are rated for thousands of hours of operation, far beyond what daily 10-minute sessions would consume in years. If you experience a defect or malfunction, reach out within 30 days for a full refund or replacement. Beyond 30 days, contact support and we'll assess on a case-by-case basis. We'd rather resolve it than lose a customer.

Yes. Nolux Aero features soft medical-grade silicone sleeves designed to fit most adult nostrils comfortably. The lightweight design allows the device to stay securely in place during your 10-minute session without creating unnecessary pressure.
