So much dust in my house

My bedroom is a complete mess.

I disinfect the space and get rid of all the dust and a few days later, it is back. It worries me that I have so much dust in my bedroom and in my house. Since most of the time in the house is spent in the bedroom, I want it to be as clean as possible. I believe that most of the complication is that I quit using HEPA air filters in my a/c unit. They were getting too expensive since I wasn’t working at the moment. Since the pandemic, they have cut my shifts short and I get fewer afternoons. I have worked from home, so I didn’t have to pay for the fuel. I also enjoy being able to work in my pajamas. So, now I am at the house more and I notice the dust more. I took a trip to the home improvement store and looked for a portable air purification unit, however that made little difference. I finally caved and called the Heating and A/C dealer. I wanted to know if there was anything they could do? They sent an Heating and A/C professional to the house, and she did a thorough inspection. After half a minute later, she told me that most of my complication had nothing to do with the air filters, but with the HVAC duct. They had to bring in a team of professional Heating and A/C HVAC duct cleaners who cleaned the entire system, repaired all the holes and cracks, and sanitized the entire system. I didn’t realize how much dirty HVAC ducts could affect my home’s cleanliness.
