Understanding the Air Quality Index (AQI)

The AQI is a standardised scale used by monitoring agencies worldwide to communicate daily air quality in terms everyone can understand.

0–50

Good

Air quality is satisfactory. Safe for all groups.

51–100

Moderate

Acceptable, but sensitive individuals may notice mild effects.

101–150

Unhealthy for Sensitive Groups

Elderly, children, and those with heart/lung conditions should limit outdoor exposure.

151–200

Unhealthy

Everyone may start to experience health effects. Limit outdoor exercise.

201–300

Very Unhealthy

Health alert — everyone should avoid prolonged outdoor exertion.

301+

Hazardous

Health emergency. Stay indoors with air purification running.

When Outdoor Air Quality is Poor — Protect Yourself Indoors

When your local AQI rises above 100, indoor air quality becomes critical. Research shows indoor PM2.5 levels can track outdoor levels within 30–60 minutes in homes without filtration. A quality HEPA air purifier running continuously reduces indoor PM2.5 by up to 90%.

HEPA filtration

Removes 99.97% of particles ≥0.3 microns including PM2.5, smoke, and allergens

Run continuously

Air purifiers work best running 24/7 — modern units cost less than £0.50/day to run

Frequently Asked Questions

How do I check air quality near me?+

You can check air quality near you by using this page's geolocation feature, or by selecting your nearest city from the list below. UK data comes from DEFRA UK-AIR monitoring stations. European data uses the European Air Quality Index (EAQI). USA and Canada use EPA AirNow and Environment Canada respectively.

What is a good AQI reading?+

An AQI of 0–50 is considered Good and safe for all groups. 51–100 is Moderate. Above 100 is Unhealthy for Sensitive Groups including children, elderly, and those with asthma or heart conditions. If your local AQI is regularly above 50, using an indoor HEPA air purifier significantly reduces your exposure to pollutants.

Why is air quality important indoors?+

Studies by the EPA and Public Health England show indoor air can be 2–5× more polluted than outdoor air. Even when outdoor AQI is low, indoor sources like cooking, cleaning products, candles, and building materials generate harmful particles and VOCs. Running a HEPA air purifier reduces indoor PM2.5 by up to 90%.

What causes poor air quality in my area?+

Common local air quality issues include traffic emissions (NOx, PM2.5), industrial sources, wood burning, weather inversions that trap pollutants, and seasonal factors like pollen or wildfire smoke. UK areas near motorways, industrial sites, or dense housing with wood burners typically have the highest pollution levels.
