Are you concerned about indoor air pollution in your home?
If you are, a good place to start would be to clean heat and cooling vents in your home.

What exactly is all this dust?

 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 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…

How it works

Self-propels deep into your vents


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.

In these 2 pictures below, you can see our blue flex hose in the vent with the dome tilted on its side so you can see what is coming out. Homeowners are very shocked when they see what we are getting out of their heat ducts. 
That's why we call it the
