"My clinical research on asthma and COPD happens at the point of care in some of the most remote, resource limited places in the world. Because of this, I need highly portable, very durable diagnostic devices reporting consistent and accurate results even under the toughest conditions. I use NDD’s devices because I know no matter the condition, the device will report accurate results."
William Checkley, MDAssociate professor at John Hopkins Bloomberg School of Public Health
"Our academic activities related to trainings and continuous learning for the specialists that take care of the respiratory health in our region, are supported by new technologies. Our experience with NDD devices has been very positive because they adapt to our necessities, they are always updated regarding new standardization and technological advances."

Infection Control
NDD inline filter solutions provide additional COVID-19 protection for those who wish to include a filter when performing tests. Filter options ensure reliable “double protection” from infection:
- The filter keeps the ambient environment clean for technicians and patients
- The Spirette protects the flow sensor from contamination
- Fully passes 24 Waveform tests as required by the ATS/ERS standard
- Available for all testing environments where filters are required
Avoid cross-contamination and reduce cleaning to an absolute minimum:
- All parts exposed to the patient's breath are single-patient-use
- Only simple surface cleaning required of the device
- No humidity can enter the device
- No special storage conditions required for single-patient use Spirettes and adapters
Visit our COVID-19 Infection Control page for more information.

FAQs Easy on-PC
Assembling the filter and adapter components is simple and easy. To add a filter (2) to the Easy on-PC, insert the Spirette normally. Then attach the (1) filter adapter (SP) to the back of the spirette and connect the filter to filter adapter (SP), as shown in the diagram below. If you have questions about how to connect or use NDD filters, please contact ndd customer support in North America at [email protected] and internationally at [email protected].
You can find the product specification on the respective product pages. The specification contains a list of all supported normal values.

No. All EasyOne products are designed to not require calibration. NDD’s patented TrueFlow technology is the only technology proven to remain stable over its lifetime. A number of independent papers have been published that confirm this long-term stability.
For organizations like NIOSH/OSHA or Social Security/Disability, where calibration checks are required, ndd offers a 3-Liter calibration syringe. A calibration check (cal-check) is not to be confused with calibration. A cal-check simply validates that the device is within calibration limits. Unlike calibration, a cal-check does not adjust the calibration values.
Yes, NDD’s products are all completely HL7 compatible through EasyOne Connect, the free companion PC software, enabling connectivity to virtually all EMRs. We would be happy to work with you to configure an interface for your particular EMR system. We are also constantly working to expand our library of dedicated integrations. For more information on connectivity with your particular EMR contact our Technical Support team.
