A pollen count is a measurement of the number of pollen grains in a given volume of air. Pollen counts, and forecasts of pollen conditions, are routinely produced and reported to the public because high aerial pollen concentration is associated with increased rates of allergic reaction for those with conditions such as hay fever and asthma .
On Saturday, the pollen index will spike to a 8.1, and Sunday’s pollen index will be at a 7.9. Monday and Tuesday are expected to hit 10.4 on the pollen index. Where is the pollen coming from?
Additionally, plants that cause contact allergies (such as rashes or itching), or that are highly poisonous when ingested even though their pollen does not cause respiratory allergies, are never given low ratings. [1] Low allergy ratings are considered to be 1 through 3 on the allergy scale.
The defined particle size ranges are 0.09–1.0 μm for smoke, 0.5–3 μm for dust, and 5–11 μm for pollen. AHAM recommends following their '2/3' rule. Air filters should be chosen for rooms so that the value of its smoke CADR is equal to or greater than 2/3 the room area in units of square feet (valid for rooms up to 8-foot (2.4 m) in ...

Pollen grains are the largest bioaerosols and are less likely to remain suspended in the air over a long period of time due to their weight. [1] Consequently, pollen particle concentration decreases more rapidly with height than smaller bioaerosols such as bacteria, fungi and possibly viruses, which may be able to survive in the upper troposphere.
