BEFORE. DURING. AFTER.

Haze

Usually Jun to Oct

Before

  • Buy N95 masks in the right sizes before the season. Kids’ faces are not small adult faces.
  • A purifier sized for one room, or build the box-fan version.

During

  • Check APIMS. Above 100: windows shut, aircon on recirculate, no outdoor runs. Strava will survive.
  • Above 200: everyone in the clean room. N95 for anyone who has to go out.
  • Above 300: consider going to R3, out of the haze.

After

  • Change aircon and purifier filters.
  • Anyone with asthma or heart conditions: see the doctor early, not at 2 am.
