I have consistently been someone who coughs. Winter, Springtime, Summer as well as fall, I have a phlegmy cough. There never seems to legitimately be anything wrong with me, however the cough is discouraging. I have had this kind of persistent cough for years, as well as I just figured it’s the way I am. Then, I discovered that the cough is really pollen irritations! I had never thought of that before. The dentist asked myself and others if I have an media air cleaner, as well as I looked at him like he was from Venus. No, I live in a rented house. I am blessed I have cooling system much less an media air cleaner. My property owner is nice, however he’s not going to get a bunch of HVAC extras for me. So, then, I found out that the cooling system air filters I have consistently used legitimately aren’t any good; You know, I use those yellow one’s, as well as I figured an air filter is an air filter, right? Well, no. It turns out that those yellow fiberglass cooling system filters are essentially useless for people. Their purpose is to help protect the cooling system unit, not the people in the house. And they don’t legitimately do all that much for the cooling system, either. My dentist commanded that if I don’t want to get a whole beach house media air cleaner, I should at least get great cooling system air filters. He commanded that I get HEPA filters as well as just see if I seem to cough less. Well, I still cough sporadically, but I do manage to sleep all night without waking up from coughing all night long. My flu symptom symptoms do indeed seem to be reduced by HEPA air filters.
