Air Filter Recommendation tool

This tool helps recommend how many of the available models of portable air cleaners at different fan speeds will be required to meet current recommendations to reduce the risk of transmission of respiratory viruses like SARS-CoV-2 in poorly ventilated indoor spaces. This is a non-profit public service that receives no commission for sales of any goods or services mentioned on this site

The database includes air cleaners using HEPA 13 filters, but if reliable data or estimates on the clean air delivery rate (CADR) for small particles (Smoke, 0.1-1 microns) is available for devices using filters below HEPA 13 efficiency, these have been included. Devices that have additional electronic cleaning features such as ionisation, plasma, and photocatalytic oxidisation have been excluded.

We cannot guarantee the accuracy of manufacturer claims on device features or performance, nor provide reliable estimates of annual filter replacment schedules which rely on characteristics of the filter and the environment in which the filter is used.
