@ameliar I was reading about the red tide several weeks ago. The articles all pointed to it being the cause of the 20% increase in pulmonolgy visits. It had suggested that people stay indoors as much as possible until the red tide is over. You may want to buy a free-standing air filter. I have one that I run in my bedroom during heavy pollen days. It has a hepa filter. That may help with air quality. It is sad about the loss of marine life.
