Real‑World Insights from Users

• Reducing cabin or hotel noise: Many users appreciate the Zen‑O Lite’s whisper-low 37 dB, making it even quieter than some home units caremedisystems.in+3reddit.com+3reddit.com+3reddit.com+5reddit.com+5bookyourmedidevice.com+5theoxygenstore.com+3caremedisystems.in+3oxyrent.com+3hospitalstore.com+9bookyourmedidevice.com+9cpaptoday.in+9cpaptoday.in+3reddit.com+3reddit.com+3respikart.com+11oxyrent.com+11cpaptoday.in+11theoxygenstore.comrespikart.com+2biotronix.in+2reddit.com+2reddit.com+1reddit.com+1amazon.in.

• Continuous vs. pulse confusion: Reddit users remind us that pulse-dose settings aren’t equivalent to continuous flow—setting “5” on portable ≠ 5 LPM continuous. This is why Nuvo Lite’s continuous delivery is preferred for prescribed flows .

• Beware of non-medical devices sold online—they often don’t truly enrich oxygen. Stick to FDA-approved models like Zen‑O or Nuvo .
