1) How long does shipping take?

Typically 3–5 business days within the U.S., depending on model, season, and destination.

2) How can I place an order?

Order online or by phone at +1 (786) 755-8063.

3) Can I fly with a portable oxygen concentrator?

Yes—most models are FAA-approved. Bring enough charged batteries for total flight time plus possible delays; carry spare batteries in cabin and check your airline’s policy.

4) How long do the batteries last?

Typically 3–5 hours with a standard battery and 8–10 hours with an extended battery, depending on model and flow setting.

5) What’s the difference between pulse dose and continuous flow?

Pulse dose delivers oxygen when you inhale (better battery life). Continuous flow provides a constant stream and is used for higher oxygen needs per prescription.

6) What warranty do new vs. certified pre-owned units include?

New: usually 1–3 years (brand/model dependent). Certified pre-owned: 6–12 months; all units are tested and refurbished to perform like new.
