Thank you for you informative video. This is the first winter in our home. I have so much dust on furniture every day! I am having so much trouble with my nose running , sneezing & its terrible. What is causing that? I was going to have my ducts cleaned, but after watching your video i dont know if i should. This HEPA filter whole house might be the answer.
It sounds like your humidity is low. I had that problem. I added a humidifier to a new furnace I had installed. I also sprayed a couch that would cause a shock after sitting on it with a little bit of static guard. I've not had a shock from anywhere since. Granted, it's only been about a month. But it seems like the shock may be gone. Also, the humidity in the house will vary depending on the outside temp (the smart thermostat will adjust the humidity in comparison to outside temp) but I'm usually running about 32% and it has been as high as 40% on a couple of days.
