I am a dealer for high end industrial air purifiers and also have air particle counters that I sell to labs, doctors, dentists, and consumers who have a an IQ above room temperature. I can tell you firsthand that the average home has air that is at least 2x as dirty as the outside air. What is in your air that you and your kids are breathing?
1. car exhaust from your garage and/or from the street
2. cleaning products
3. a myriad of toxic substances kicked up when you vacuum (all of us have Dupont stain protection in our bloodstreams) Isn't this a nice gift you are giving for your baby to start his/her life?
4. smoke from fireplace, your neighbors fireplace
5. every synthetic item in your home will shed particles and of course it enters your bloodstream
6. Particles from other parts of the world including China. And of course the hot radiation particles from nuclear power plant releases (ooops not supposed to talk about that little factoid)
If your kid gets asthma it is almost certainly your own fucking fault for being complacent.
Typical particle count outside in an area without much pollution is about 200,000 per cubic foot. In Los Angles it is typically over 1,000,000. An LA freeway or busy road is about 2,000.000 to 3,000,000. People actually jog along busy roads thinking they are improving their health.
Every time you drive down a busy road or freeway you are breathing in elevated levels of particulate and that particulate is certainly not good for your health to say the least. People who spend long periods of time in bumper to bumper traffic on a daily basis might be better off sitting home smoking Marlboros.
The average drug/vaccine pushing whore doctor won't tell you these things because there is not way for them to make money. Just like there is no money to be made in telling you to stop cooking your food to death.
Also every year people spend hundreds of millions of dollars on completely bogus air purifiers. Almost none of the air purifiers do jack shit other than take out the large particles such as pollen. So if you are allergic to pollen then buy a cheap Honeywell at home depot and you are golden. If you are trying to actually purify your air then you need to buy a hight end system that filters out nano particles. It is the nano particles that stay suspended in the air indefinitely and enter every cell of your body. But of course Americans love buying infomercial garbage so I guess the way to make money is sell them garbage and focus on marketing instead.
Scientists and doctors have known about the true dangers of air pollution for several years and more recent studies by UCLA have shown that you are just as fucked if you live several blocks from a busy road but like I said, pharmaceutical companies have no way to profit from this so they don't pay their whore doctors to warn you.
