Could a filter retrofit disturb the pressure relationship of an isolation room?

It can: the filter’s resistance adds to the pressure the system’s fan works against, and the label directs that it is not used where it would restrict airflow beyond the system’s specification; the pressure relationship of a room is set and verified by the people who run that system.

The label prints the rated airflow and the maximum face velocity, and it states: “Do not use where this filter would restrict airflow beyond the system’s specification.” and “The frame edges can be sharp. Improper installation can reduce airflow or damage the equipment.” Results in a building depend on the system, the airflow, and how well the filter fits its track. The label states where to use the filter: forced-air heating, ventilation and air-conditioning systems in homes, businesses and institutions that take its panel size and run at or below the rated airflow and maximum face velocity printed on it. The Terms of Use state that Site Content is not to be used to diagnose, treat, or make a patient-care or infection-control decision.

Would installation require interruption of a critical ward's air service?

Changing the filter means switching the system off at the thermostat or at the unit’s disconnect, and following the label's caution for the used filter.

How long a system can be off is decided by the people who run it.

The label’s directions are: “Switch the system off at the thermostat or at the unit’s disconnect before opening the filter access.” Then the used filter is removed and discarded as directed under storage and disposal, the new filter is fitted into the filter track with the airflow arrow pointing toward the blower, the fit is checked square in the track with no gap at the frame, the access panel is closed and the system is switched back on. The label adds: “Do not run the system with no filter in the track.”
