The CO Check Pro is a screening device. Blood tests and
examinations are required to validate possible CO poisoning.
The CO Check does not protect property or persons, and should not
be used for industrial or domestic purposes (heating, faulty
fireplace). It does not meet the standards of protection of persons
against CO pollution.
The SafeBreath filtered mouthpieces and regular disposable cardboard
mouthpieces are single-use only. Re-use of these single use mouthpieces
can increase the risk of cross infection and the mouthpiece should be
disposed of after use by the subject.
