How essential is an air purification system to all?

I live in a small home right next to a very dusty street in addition to our home is consistently dusty despite me not opening the windows throughout the day, and a mile down the road is a papermill factory that is consistently releasing some black smoke that I think is toxic.

I used to guess that the coolness gave by the heat pump was enough to keep the air within our home clean enough to breathe until I started suffering from respiratory troubles. A neighbor of mine who worked at the local company recommended that I get an air purification system to help improve air quality. This was a good proposal 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 proposal gave by the company to enable homeowners to own air quality systems. They had introduced this proposal when Covid hit. I only needed to pay for the installation process in addition to the labor. The servicemans came the following week to install the media media air cleaner. I had bought 1 that came with air ducts in addition to so they had to put up the HVAC duct in addition to proceeded with the duct sealing process. I got a basic dial temperature control that could do the work. The servicemans took me through the process of cleaning the washable filters to maintain clean 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 position in healing our respiratory troubles.
