I had been having the worst time with my dust sensitivities in the last few weeks when in my home.
After some investigating, it turned out that the reason for this was because the ductwork of my HVAC system had not been cleaned in a long time! Every single time my central HVAC system would go on, it would end up spreading dirt and dust around the home out of the air vents, but once I figured all of this out, I called my specialist to clean the ductwork of my central heating and cooling plan unit.
This was a little more extravagant than your regular ductwork cleaning, because it had been so long. A deep cleaning needed to be done. I got the deep ductwork cleaning done, and then within the same morning, I already observed a difference in my dust sensitivities! I bought a portable air purification plan to clean the indoor air pollen levels from room to room to get rid of all the dust and dirt that was in the air and then all was ok once again. I will keep up with my ductwork cleaning from this moment forward, as I do not want something like this to ever happen again.
