## CleanAirNav beta

On the map, zoom to a place that interests you or tap on the button on the bottom right:

Orange: outdoor seating available or takeaway

Black: no outdoor seating available

Grey: outdoor seating unknown.

You can choose to show all restaurants ad hotels with unknown outdoor seating.

Additionally shown: drinking water fountains, toilets, picknick places, vending machines.

### **Advanced settings / OpenStreetMap**

I contribute to OpenStreetMap by adding missing information about outdoor dining options.

To support this, the app displays all restaurants and hotels on the map — shown in gray if no outdoor seating data is available.

For each location, the OSM object ID is visible.

I use this ID to update missing tags like [outdoor\_seating = terrace](https://wiki.openstreetmap.org/wiki/Key:outdoor_seating)

### **Apple: Supported OS Versions and Devices**

Starting with iOS 16: all iPhones since 2017 are supported, including iPhone 8 / 8 Plus, iPhone X, and newer.

iPadOS 16 or later:

- iPad (5th generation) and newer
- iPad mini (5th generation) and newer
- iPad Air (3rd generation) and newer
- All iPad Pro models (starting from 1st generation)

visionOS: All versions of Apple Vision Pro are supported.

### **Android**

An Android version of the app would have to be developed by someone else.

## I want to know where HEPA filters are in use and where ventilation systems operate with a high rate of outdoor air.

Me too.

Unfortunately, this kind of data is currently not available in OpenStreetMap.

## If you’re familiar with OpenStreetMap:

I would love to define and promote tags for things like HEPA filters, high-quality ventilation with strong outdoor air exchange, or hotels that offer outdoor breakfast options.

If you’re interested in contributing to that effort, please contact the author.
