Why NObreath®?

Using FeNO measurements to evaluate airway inflammation in asthma represents a significant advance in respiratory medicine2, but until now it has been an expensive test to deliver in everyday practice. Recommended by NICE4 and conformed to ERS/ATS guidelines5, the NObreath® FeNO monitor is the essential tool for asthma.

Features and benefits include:

  • Unlimited FeNO testing*
  • Low-cost device and consumables
  • Easy-to-use
  • Reliable and accurate results
  • Low maintenance
  • Fully portable and handheld FeNO device
  • Colour touch screen
  • Adult and child profiles
  • Ambient NO measuring
  • CE marked

*Subject to servicing and general wear and tear

Integrating a FeNO device into your patient pathway shouldn’t come at a high price; the NObreath® FeNO device price is tailored to your usage levels and we are confident we can beat or reduce your alternative/current FeNO device cost.

NObreath® Consumables

Years of research and vigorous testing ensures our Bedfont® products and consumables are not only safe for consumer use, but compliant with Medical Device Regulations. Use of counterfeit or non-Bedfont® approved accessories and consumables may result in loss of performance and/or damage to your device. This risk of incorrect results could adversely affect patient care. We also remind you that counterfeit and/or non-Bedfont® accessories and consumables do not possess the quality and reliability of the original manufacturer products, nor have they undergone the Toxicology tests to ensure they are fit to be used orally, and therefore their safety and infection control efficacy cannot be guaranteed.
