How does dust affect the efficiency of a heater?

"Dust can accumulate on the heating elements and in the air filters of a heater, reducing its efficiency. This can cause the heater to work harder to produce the same amount of heat, leading to increased energy consumption and higher utility bills. To maintain the efficiency of your heater, make sure to clean it regularly and replace the air filter as needed."

The dust lamp lights up and won't go out. The dust was blown away nicely. It says to replace the air filter, but where can I find it? Can I replace it myself?

This heater does not have air filters to clean, or spare parts?

How to open up metal front cover. I found two screws, but the boys were fast. Where is the T-10 screw that I read about so I can get inside and clean this thing?
