Air cleaners and purifiers
Canonical HVACentric knowledge for residential questions on this topic.
DIRECT ANSWER
Air cleaners can reduce some airborne particles, but no unit removes every pollutant and they do not replace source control or appropriate ventilation. Match a portable cleaner’s capacity to the room and consider noise at the operating speed you will actually use. For central filtration, confirm that the HVAC system can handle the filter without harmful airflow restriction.
