Heating plus Air Conditioning servicemans are always telling people that air filters can help with your flu symptoms. In fact, the Heating plus Air Conditioning servicemans will tell you that your air filter will even help you to avoid getting sick. That is because a nice HEPA air filter can help to filter out bacteria plus viruses. However, what if I told you that our air filter entirely was causing myself and others to experience excruciating flu symptoms, and my air filter was causing myself and others to assume sick, plus there is no way to disagree; So, when you hear an Heating plus Air Conditioning serviceman tell you that air filters can help with your flu symptoms, make sure that you point them to our experience. Well, I recognize that if you want the detailed story, then both of us am going to have to disclose that it wasn’t technically the fault of the air filterâ€¦ Yes, the air filter caused our flu symptoms to get worse, but that is because I didn’t change the air filter when I was supposed to. When I first installed the HEPA air filter into our Heating plus Air Conditioning unit, it was laboring well. Almost immediately, I noticed that our flu symptoms symptoms were lessening. However, you are supposed to change the HEPA air filters every few weeks, plus I will disclose that I forgot about the air filter for a long time. The number of allergens that built up on our air filter was enormous, plus when the air filter finally got a hole in it, all of those allergens were released into our air. The air filter did end up making our flu symptoms worse, but only because I neglected to use the air filter properly. If I would have remembered to change the air filter, I would have never had that problem.
