Problem Statement
Currently there exists no way to indicate the presence of air filtration at a building or amenity. For those who are immunocompromised or who care for immunocompromised individuals the presence of air filtration at a venue or amenity can be critical information they need to know in advance of attending for their or others safety.
Proposal
This proposal will allow tagging of air_filtration=yes/no on both ways with building=*or building:part=* and nodes with amenity=*to indicate the presence of air filtration as well as the following sub-tags to specify the type of air filtration present
air_filtration:schedule=permanent;intermittent;event_based;on_demandair_filtration:schedule:hours=*Standard OSM Schedule format for intermittent air filtration.air_filtration:pressure=neutral;positiveair_filtration:type=mechanical;electrostatic;UVair_filtration:rating=*Takes whatever the rating for the air filtration system is as a value.
Rationale
These tags both allow the presence of air filtration to be added to the map and the type of air filtration to be specified separately.
The tag format of air_filtration:*=*has been chosen to be easily understandable and as short as possible. filtration:*=*was not chosen as it does not contain enough specificity and may easily be confused for meaning something else.
Tagging
| Key | Value | Description |
|---|---|---|
| air_filtration | yes | Indicates the presence of air filtration in an indoor space, even if intermittent. |
| no | Indicates the absence of air filtration in an indoor space. | |
| air_filtration:schedule | permanent | Air filtration is always active while the space is open. |
| intermittent | Air filtration is sometimes active. | |
| event_based | Air filtration is present for some events in a space but is not on a fixed schedule. | |
| on_demand | Air filtration is by request of event organisers, customers or visitors. | |
| air_filtration:pressure | neutral | The space is kept at atmospheric pressure or close enough to it not to matter. |
| positive | Air is pumped into the building through the filtration system to create positive pressure meaning outside contaminants like pollen cannot enter. | |
| air_filtration:type | mechanical | Mechanical filtration of the air through some sort of permeable membrane. |
| electrostatic | Filtration through electrostatic forces. | |
| uv | Killing bacteria and viruses in the air by destroying them with UV light. Not technically filtration but fits well enough for OSM purposes | |
| air_filtration:rating | The rating of the air purification system | This key can accept any rating for air purification or air sterilisation, for instance HEPA, MERV and ULPA and the sub-ratings for each are all acceptable. This could also accept the classification of a clean room. |
