Why I was suffering from flu symptoms despite having correct Heating, Ventilation, plus A/C filters in site

I also purchased a HEPA-certified sealed vacuum cleaner since they are better at trapping dust

I am the most disciplined guy in maintaining our Heating, Ventilation, plus A/C unit. I change our Heating, Ventilation, plus A/C system’s air filters often plus scrub our unit every few weeks. I also schedule annual Heating, Ventilation, plus A/C tune-ups to keep our Heating, Ventilation, plus A/C plan in its best laboring condition. However, I have been experiencing increased allergic reactions, especially when I am in the house, however my flu symptoms got so bad that I had to book an appointment with our physician. My nurse offered myself and others some antihistamines, but our allergic bouts continued. When the Heating, Ventilation, plus A/C serviceman came for the unit’s repair, I told him about our flu symptoms, plus he told myself and others to start using the right air filters to help fight our flu symptoms. I substituted our filters with the High-Efficiency Particulate Air (HEPA) air filters. These air filters have multi-layered netting. They have effectively removed dander, tiny pollen grains, mold, plus other allergens from our home’s indoor air. These HEPA filters remove 99.97% of particulates in the air. I seldom experience allergic reactions, plus our health has improved. I also open our windows on the opposite side of the room. This action increases airflow within our home. It expels pollutants from our beach lake house plus allows scrub outside air to flow into our indoor space. I also purchased a HEPA-certified sealed vacuum cleaner since they are better at trapping dust. I no longer take antihistamines for our flu symptoms. However, I still scrub plus substitute our air filters as often as necessary plus continue with our correct Heating, Ventilation, plus A/C plan repair routine.
