What Is the NDD EasyOne Air Spirometer?

The NDD EasyOne Air (Model 2500-2A) is a professional-grade medical spirometer manufactured by NDD Medical Technologies, a Swiss company with decades of expertise in respiratory diagnostics. This digital spirometer measures key pulmonary function parameters, including FEV1, FVC (Forced Vital Capacity), FEV1/FVC ratio, PEF (Peak Expiratory Flow), and more — all aligned with ATS/ERS spirometry guidelines.

What sets the EasyOne Air apart from other spirometry devices is its patented TrueFlow™ ultrasonic technology, which eliminates the need for calibration while maintaining measurement accuracy that meets or exceeds standard requirements.

Who Should Use the EasyOne Air Spirometer?

This medical spirometer is ideal for a wide range of healthcare settings and professionals:

For Healthcare Professionals:

• Pulmonologists — performing diagnostic spirometry for obstructive and restrictive lung disease
• Primary Care Physicians — routine PFTs for COPD, asthma screening, and pre-surgical assessments
• Occupational Health Clinicians — OSHA compliance testing and workplace respiratory surveillance
• Respiratory Therapists (RTs) — Lung function monitoring for both inpatients and outpatients
• Family Practice & Internal Medicine — Spirometry in the office without a pulmonary lab

For Healthcare Settings:

• Small independent clinics looking for the best spirometer for small clinics (no calibration technician needed)

EasyOne Air Spirometer for COPD & Respiratory Disease Management

Chronic Obstructive Pulmonary Disease) is diagnosed and staged using spirometry — specifically the FEV1/FVC ratio. The EasyOne Air provides the precision needed for COPD staging per GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria. It is also widely used for:

• Asthma - assessing bronchodilator reversibility 
• Pulmonary Fibrosis - detecting restrictive patterns via FVC decline
• Occupational Lung Disease - serial monitoring of at-risk workers
• Pre-operative Assessment - Surgical Risk Stratification

When used under a doctor's supervision, this spirometer is also recommended by many clinicians for home monitoring of COPD. However, clinical-grade testing in a professional environment remains the standard of care.
