A single-use antiviral and antibacterial filter consisting of a housing made of medical polypropylene and a highly specialized filter element. The filter is used in spirometry testing, protecting the device from contamination by the patient - pathogens and aerosols generated during air inhalation into the device. It also increases the hygiene of the test by protecting both the patient and the device from cross-contamination. Different product variants ensure compatibility with most spirometers on the market (including Lungtest, Spirolab, Microlab, Aspel).

A disposable paper mouthpiece, non-sterile, is an accessory for the spirometer. The mouthpiece consists of 4 layers of paper rolled into a tube shape. The outer layer of paper is additionally coated with PE to increase user comfort. Different product variants ensure compatibility with most spirometers on the market (including Lungtest, Spirolab, Microlab, Aspel).

The clip is used in respiratory tests to prevent airflow through the nostrils and to ensure that air is conducted only through the mouthpiece to provide accurate measurements. It also serves as an element to increase the hygiene of the test by protecting the patient from cross-contamination.
