Good
Beautiful. In many parts of Tasmania background PM2.5 is less than 5 and hard to beat.
Summaries are built by the nightly rollup, so today does not appear until tomorrow.

| PM2.5 (µg/m³) | What the conditions are like | What this means |
|---|---|---|
|
0 - 12.5 Good |
Beautiful. In many parts of Tasmania background PM2.5 is less than 5 and hard to beat. |
|
|
12.5 - 25 Fair |
Generally good, it might appear a little hazy. |
|

25 - 50 Poor |
The air is likely to be smoky. Generally, you are able to see or smell smoke in the air when PM2.5 is over 25. |
|
|
50 - 150 Very Poor |
Visibility will be poor, and conditions may be unpleasant. It will likely be very smoky if PM2.5 is over 100. |

150+ Extremely Poor |
It will be very smoky and unpleasant for everyone. |

In general, if PM2.5 levels are higher, at poor or very poor and have been for more than a day, it is important to take action. Poor air quality for several days has a greater health impact than a brief episode lasting a few hours. The higher the PM2.5 the more likely this is to happen.
Beaumaris-weather.com hosts a PurpleAir PA-II-SD air quality sensor on the east (ocean) side of the house. The results are automatically sent to the purpleair.com website for aggregation and analysis. The readings above are from both sensors in the PA-II-SD sensor unit. We also store our Air Quality Data in onsite Databases, which is the source of the readings and charts on this page.
PurpleAir PA-II, dual laser counters, A/B averaged. PM2.5 uses the ALT conversion (cf=3.4) computed from particle counts, matching the Tasmanian scale used on the PurpleAir map. Health categories apply to the rolling 1-hour average.
