Straight answers to what people ask us most before buying an oxygen concentrator. Can't find it here? Call 1-786-658-5217, Monday–Friday 8am–8pm ET, or email longbreeze.support@gmail.com.

Do I need a prescription to order an oxygen concentrator?

No. Long Breeze machines are sold as general wellness devices for everyday breathing comfort, so you can order directly. They are not FDA-cleared prescription medical oxygen equipment. If you are managing a diagnosed health condition, talk with your doctor first — they can tell you whether supplemental oxygen suits you and at what setting.

How fast does it arrive?

Orders are processed in 1–2 business days, then arrive in 3–5 business days within the US. Shipping is free on every order, with no minimum.

What do the oxygen concentration figures (33%, 90%, 93%) mean?

It is the oxygen concentration a machine delivers at its rated settings, measured under standard test conditions. Room air is about 21% oxygen. Our 33% models add light enrichment; our 90–93% models deliver high-concentration oxygen closer to the purity of prescribed home oxygen. The delivered figure usually drops as you turn the flow rate up. The figure for each machine is on its own product page.

Can I use an oxygen concentrator overnight?

It depends on the machine — check the specifications on its product page — and on you. Ask your doctor whether overnight use is right for your situation and at what flow setting.

What is the difference between the machines for people and the machines for pets?

The three portable models for people (33% and 93%) are built to be carried and used day to day. The two veterinary units (SH-O1 and SH-O5) are the oxygen source for home or clinic care of dogs, cats and small animals; the SH-O5 goes down to 0.5 L/min for very small animals and the SH-O1 has a built-in nebulizer. Use the veterinary units under guidance from your vet.

What if the machine breaks?

Call us at 1-786-658-5217. Inside the first year we repair or replace it under warranty, and we will tell you which on the phone. After the first year we repair at a flat rate. Phone support is free for as long as you own the machine.

What is the return policy?

You have 30 days from delivery to return an eligible item. Unopened items returned within 30 days carry no restocking fee. Opened items returned within 30 days may carry a restocking fee of 15% of the product price. You are responsible for return shipping either way. If we sent the wrong item or it arrived defective, that is on us — we cover the return and send the right one. Full terms are on our refund policy page.
