Pollen Count


Two of our AllerVie Health locations (Birmingham, Alabama and Draper, Utah) operate pollen counting stations that provide daily pollen counts to the AAAAI’s National Allergy Bureau™ (NAB™), which certifies those pollen counts for national distribution.

The NAB is the most trusted resource for accurate pollen and mold levels and provides excellent resources to people who like to monitor pollen levels closely. You can easily search the interactive map on the NAB website to find a pollen counter station in your area and click on the station heading to view the allergen report.

You can also sign up via email with the NAB to save access to your preferred stations and receive notification emails with the daily pollen count for your area!

Learn more at the AAAAI’s National Allergy Bureau website.

What Do the Pollen Levels Mean?

Collection stations nationwide report their certified pollen count data to the National Allergy Bureau. The “count” data shows the number of pollen grains or mold spores present per cubic meter of air on that day.

Pollen and mold levels are determined by the National Allergy Bureau and have been translated into these four levels based on the counts for the majority of days:

  • LOW – Concentrations less than the median or 50th percentile (half of the counts were below median)
  • MODERATE – Concentrations between 50th and 75th percentile
  • HIGH – Concentrations between the 75th and 99th percentile
  • VERY HIGH – Above the 99th percentile (99% of the counts are below this level)

Why Do We Count the Pollen?

It is important for those who experience allergy symptoms to stay aware of the pollen levels, even when they are low, so they can begin their appropriate medications and precautionary measures (like avoiding outside activities, bathing before bed, etc) as soon as possible. While the pollen count measures the concentration of pollen in the air, it is not a measurement of, or correlated, with an individual’s possible symptoms.

A “low” pollen count does not always correlate with a low level of symptoms, just as a very high count does not necessarily mean a higher level of significant health effects. The higher number of pollen grains in the air, the more precautions patients should generally take. We encourage all allergy sufferers to consider seeing an AllerVie board-certified allergist for accurate testing and the right, most effective treatment plan for them.

What Is Pollen?

Pollen is the male fertilizing agent in plants and consists of microscopic, lightweight, powdery granules. The two main modes of pollen transfer are wind pollination and insect pollination. Plants bearing large amounts of pollen distributed by the wind are the main culprits for causing allergy symptoms because the pollen is light and travels in large quantities for many miles in the air. Wind pollinated plants are not particularly colorful or fragrant, and include grasses, many trees, and weeds.

Insect pollinated plants such as fruit trees and ornamental flowers attract insects with odor, nectar, and brilliant colors. Insect pollinated plants usually pose fewer problems for allergy sufferers since this type of pollen is too sticky and heavy to be transported very far by air.
