How essential is an air purification plan to all?

I live in a small house right next to a really dusty street in addition to our house is always dusty despite me not opening the windows throughout the afternoon. A mile down the road is a papermill factory that is always releasing some black smoke that I assume is toxic. I used to think that the coolness gave by the heat pump was enough to keep the air within our house wash enough to breathe until I started suffering from respiratory complications. A associate of mine who worked at the local supplier recommended that I get an air purification plan to help improve air quality. This was a great idea however the only issue was that I did not have the funds to get the new system. I visited a particular company in addition to explained our predicament. The kind salesman introduced me to a financial idea gave by the supplier to enable homeowners to own air quality systems. They had introduced this idea when Covid hit. I only needed to pay for the installation process in addition to the labor. The specialists came the following week to install the media air cleaner. I had purchased a single that came with ductworks in addition to so they had to put up the ductwork in addition to proceeded with the duct sealing process. I got a basic dial thermostat that could do the work. The specialists took me through the process of cleaning the washable filters to maintain wash air filters. They also tied up the first duct cleaning which was to happen 3years after installation. The new heat in addition to A/C products played a big career in healing our respiratory complications.
