 Dust in your home, What is it? clean vents

What is all this dust in my home?

 Dust that collects on your TV, tables, windowsills, kitchen countertops,  and on those picture frames that are so hard to get clean is made mostly from dead human skin cells. In other words,
your home is filled with former bits of everyone who has lived in your home.
This then will collect in your air ducts and be recycled every time your system runs. 
You'll shed more than 8 pounds (3.6 kilograms) of dead skin each year. It gets even grosser: Your home is also filled with trillions of microscopic life forms called dust mites that eat your old dead skin.

This is why we recommend adding disinfecting air ducts to all our clients.

Disinfecting Air Ducts
Best air duct cleaners are Fast, Efficient and Affordable

With RamAir, We blast debris from ducts with highly compressed air, this method has been endorsed by the National Air Vent Cleaners Association. This system has been lab & field tested to do a better job of removing the dust and debris from duct walls and will not damage any type of ducting. The 1” diameter Teflon Blasting Ball will go and fit deep into and slip around the corners of ducts with incredible ease. The powerful air blast reaches into corrugations of flex ducting that brushes can miss, doing a better job of cleaning. As an added bonus, you will be absolutely shocked when you see all the debris swirling through the clear Vacuum Box… 

Comet's better and faster than our competition resulting in better prices for our customers
Here are 2 heat vents we did recently in a house less than 4 years old. What you're seeing is lots of construction debris. This is normally painted overspray, Sheetrock dust, insulation, and sawdust. When your furnace turns on, this is constantly being forced into the air you breathe, the main reason the environment in our homes is the most contaminated.
