What's the air quality in North Devon? NO₂ 3.4 µg/m³
In 2025 the average resident of North Devon lived with background NO₂ of 3.4 µg/m³, Very Low for England and Wales and below the WHO guideline of 10. PM2.5 was 5.5 µg/m³, Very Low for England and Wales and 1.1 times the WHO guideline of 5. The typical area in England and Wales has NO₂ of 7.2 and PM2.5 of 7.4 µg/m³.

All house prices in North DevonIs the air quality good in North Devon?
Background NO₂ in North Devon is 3.4 µg/m³, below the WHO guideline of 10, and lower than the typical area (7.2). That puts it in the Very Low band. Background PM2.5 in North Devon is 5.5 µg/m³, 1.1 times the WHO guideline of 5, and lower than the typical area (7.4). That puts it in the Very Low band. Most of England and Wales is above the WHO guideline for PM2.5, so the bands compare places with each other rather than giving a pass or fail.
Nitrogen dioxide (NO₂): 3.4 µg/m³
NO₂ level is Very Low, on a scale from Very Low to Very High.
Very Low means the lowest fifth of areas in England and Wales for NO₂.
| Very Low | up to 4.7 |
|---|---|
| Low | 4.7 to 6.5 |
| Typical | 6.5 to 7.7 |
| High | 7.7 to 9.2 |
| Very High | over 9.2 |
WHO guideline: 10 µg/m³ (in the Very High band). UK legal limit: 40 µg/m³.
Fine particles (PM2.5): 5.5 µg/m³
PM2.5 level is Very Low, on a scale from Very Low to Very High.
Very Low means the lowest fifth of areas in England and Wales for PM2.5.
| Very Low | up to 6.0 |
|---|---|
| Low | 6.0 to 7.2 |
| Typical | 7.2 to 7.7 |
| High | 7.7 to 8.2 |
| Very High | over 8.2 |
WHO guideline: 5 µg/m³ (in the Very Low band). UK legal limit: 20 µg/m³, with a target of 10 µg/m³ in England by 2040.
The bands split every area we cover into fifths by its level, from Very Low to Very High. The map uses the same colours.
