MTEH oxygen enrichers

Good questions. Clear answers.

Questions about the MTEH FYY-01 and FYY-03 portable oxygen enrichers.

How do the FYY-01 and FYY-03 oxygen enrichers differ?

FYY-01 offers a fold-away handle and two continuous-flow settings. FYY-03 has separate Continuous and Breathe controls and a 30 Wh battery. Compare the product details to choose the format and controls that suit your setup.

What does 30% oxygen at the outlet mean?

It describes oxygen concentration at the device outlet, not the concentration you inhale or a measurement of blood oxygen. It is not a promise of a health effect.

Can MTEH oxygen enrichers replace prescribed oxygen?

No. These products are not a substitute for prescribed oxygen therapy or emergency care. Follow the device instructions and advice from a qualified medical professional.

Does the ten-minute screen break describe an oxygen-enricher session?

No. It is our reminder to take a screen break, not guidance for using the device. Follow the instructions supplied with your MTEH oxygen enricher. The blood pressure monitor has its own measurement routine and instructions.

Will the oxygen enricher carry the MTEH label?

Yes. Products retain their original manufacturer labels, as shown in the images. Seravni is the store where you shop for them.

Can I use an MTEH oxygen enricher on a flight?

Do not assume in-flight approval. Check the device documentation and your airline's requirements before travelling with or operating the equipment.

How should I care for an MTEH oxygen enricher?

Keep vents clear, use the specified power supply and keep the equipment away from flames, smoking, oil and water. Switch off before cleaning and follow the supplied instructions for tubing and accessories.
