Low Dust Mite Allergy Risk

Lower dust mite habitat risk scores higher using indoor-equivalent relative humidity and damp-hour proxies.

Scale0-100

Higher values rank better for this score.

How It's Calculated

The latest published score is normalized to a 0-100 scale. The method below explains what the score rewards, with technical source metadata available for audit.

Scoring Method

How the ranking is built

Low Dust Mite Allergy Risk is an environmental proxy for places less favorable to indoor dust-mite humidity conditions.

  1. 1

    Dust mite burden is a weighted blend: 32% indoor-70F hours at 50% RH or higher, 23% indoor-70F hours at 60% RH or higher, 20% indoor-70F RH excess, 15% hours at 80% RH or higher, and 10% warm hours at 60% RH or higher.

  2. 2

    The burden is confidence-shrunk when station evidence is weaker.

  3. 3

    The score is inverse percentile-rank normalized over the full scored distribution, so lower proxy risk scores higher.

What This Score Means

Low Dust Mite Allergy Risk is an environmental proxy for places less favorable to indoor dust-mite humidity conditions.

Statistics Feeding This Score

  • Indoor-70F hours at 50% RH or higher

    Outdoor moisture converted to a 70F indoor relative-humidity proxy.

    Source: NOAA U.S. Climate Normals, hourly
  • Indoor-70F hours at 60% RH or higher

    Stronger dust-mite habitat signal from indoor-equivalent humidity.

    Source: NOAA U.S. Climate Normals, hourly
  • Warm hours at 60% RH or higher

    Annual count of warm outdoor hours that are also humid.

    Source: Derived from NOAA hourly normals

Source Data

Source: NOAA U.S. Climate Normals, hourlyNOAA NCEI 1991-2020 hourly station normals used for dew point, muggy-hour, and heat-index humidity proxies.

Known Limits

  • Hourly station normals are environmental proxies, not forecasts or indoor-environment measurements.
  • Nearby stations are weighted by distance and elevation fit, then lower-confidence estimates are shrunk toward the all-place mean.
  • Allergy-risk scores do not include local spore counts, medical outcomes, building ventilation, or indoor humidity.
