The HVAC solution to pollen is to maintain positive pressure in the building, good filtration, and implement some good cleaning practices. That however, is not what we’re talking about today. We’re talking about the science of pollen and why we have pollen allergies, because few HVAC Blogs look at this type of science, but we do. Plant Reproduction Most complex life on Earth needs two organisms to reproduce. You have two parents, your dog had two parents, and the tree in your front yard, probably had two parents. The thing is though, trees and flowers can’t walk up to each other to reproduce, they’re just static-things that shift in the breeze. Something has to move genetic material from one plant to the other. Pollen is how plants reproduce. They’re hardy cells that get carried off into the wind in such vast quantities that they’re all but guaranteed to swarm a compatible plant. These cells contain that tree’s genetic material and they’re designed to mix with another plant to produce seeds that will eventually grow into another plant. This is an ongoing process, but it’s worse in the Spring when plants are bursting back to life after a long, dormant winter. Varying weather conditions will cause days with more or less pollen.
