In the past, NDD Medical’s spirometers required the use of filter adapters to attach a filter to the unit. Now, NDD have developed their own EasyOne Filters that are device specific and don’t require the use of an adapter. The EasyOne Filters come in two versions: the SP and the FT. The EasyOne Filter SP is for the Easy on-PC unit with the spirette mouthpiece only. The EasyOne Filter FT is for the EasyOne Air unit with the FlowTube mouthpiece only.
The uniquely designed EasyOne Filter ensures highly accurate test measurements, keeps the ambient environment clean, protects from cross-contamination, and meets the 2019 ATS/ERS spirometry standards for accuracy. See filter properties below:
