The air purification system helped our flu symptoms

Does anyone else have flu symptoms? I never had much of a concern before I moved to this town.

I assumed it was just the time of year, & there was excess pollen in the air, however they are persistent. I even started taking flu symptom medication every afternoon, & while it does help a little I still think itchy & sick almost all the time. My mother ordered myself and others something nice on Amazon to help with our problem. It is a small however powerful air purification system, which she recommended myself and others to leave next to our bed when I sleep at night. The air purification system actually has made a difference in how I feel, however the flu symptoms still persist! Finally I decided to call in the professionals, & had a certified Heating & A/C tech come over to test the air quality of the house. The Heating & A/C tech asked if I had any pets, & I said I couldn’t have pets because of our flu symptoms. That was the solution to the concern laid bare, because she said there were high trace amounts of pet dander in the ventilation system, & that is what was bothering myself and others so much! She requested a full cleaning of all the ductwork & scrubbing out the air vents. That repair cost a little bit more than I wanted to pay, despite the fact that I couldn’t sacrifice our health, so I asked her to clean the ductwork for me. The following afternoon our HVAC ducts were sparkling clean, & I was breathing much easier than I had in a legitimately long time.
