ndd EasyOne Filter SP for Spirette and Easy-on-PC Spirometer

The ndd EasyOne Filter SP's patent-pending design ensures highly accurate spirometry measurements while maintaining a clean environment and preventing cross-contamination when used with ndd's Easy-on-PC spirometer.

This filter meets the 2019 Update to the ATS/ERS spirometry standards for accuracy and provides an optimal fit with minimal resistance.

Testing Information:

1. Waveform tests passed the ISO 26782 standards as required by ATS/ERS. The 13 waveform testing is the new standard, replacing the previous 24-waveform testing. They simulate different patient groups, including COPD, asthma, obstruction, restriction, smaller and larger lungs, and high and low flows.
2. Filtration efficiencies were tested at Nelson Labs, United States.
3. The resistance of the entire system, including the ndd Spirette and EasyOne Filter, is smaller than 1.5 cm H₂O L/s "up to" or "at" 14 L/s.
4. The accuracy of FEV₁, FEV₆, and FVC are demonstrated in the 13 waveforms tests performed according to ISO 26782:2009/Cor 1:2009 with applied ATS/ERS 2019 Spirometry Standards limits.
