Does pollen lose its ability to trigger allergies?

Question
Does pollen deteriorate or rot? Does pollen lose its ability to be an allergen over time?
Answer

Because it is organic, I would suspect pollen would break down over time. I recommend that you keep windows closed during pollen season. Run the HVAC with filters that can trap pollen and vacuum weekly. A visit with a board-certified allergist can also help. Discuss treatment options so you can live comfortably with allergic rhinitis.
