Air filtration devices to enable spirometry?
Is anyone using an air filtration device to achieve the required room air change rates to run a spirometry service? Or has anyone looked into these devices and has an opinion on them?
We are running an integrated care service and are going round in circles between planning to use highly-ventilated rooms, in-car Spiro, and a few other options. In theory it seems like an attractive idea to use a device like this:
which would enable us to use a normal clinical room for spirometry. My big question is whether these types of devices can filter COVID-19.
Any ideas / opinion / experience?
