I have this philosophy about my family’s home and life. If the best is the best and the second best is just good enough, I’ll go with the best. With our HVAC system, the best is a HEPA air filter. I love our family and I always want them to have the best. With the HEPA air filter, I think our air quality is always going to be scrub and healthy. My family is going to have less chance of suffering from dust irritations and asthma. My youngest had always had drastic dust sensitivity reactions. Once we got the current HVAC unit and installed HEPA air filters, his dust sensitivity symptoms waned. We soon added the air cleaner, and it was like a miracle. I will not use anything other than HEPA air filters in our HVAC system. Last week, my sister called me and told me she didn’t know what to do. She was in a panic because her newborn was coughing and sneezing and she couldn’t stop it. She said the symptoms are just getting worse and yet the doctor said there wasn’t anything wrong. When she had her baby at the doctor’s office, he wasn’t showing any signs of dust sensitivity. I told her that maybe she was using the wrong air filters in her HVAC system. She thought I was crazy. I told her I only use HEPA air filters and our entire family has been feeling better ever since. I got to babysit our several month old nephew while my sister and her spouse went to town to purchase a portable air cleaner for their home and HEPA air filters for the Heating and A/C system.
