I have done research for 11 years in indoor air quality and healthy living technologies. You will find that most doctors and health professionals will treat the symptoms and not pay attention to the cause.
Are you aware that according to the E.P.A., about 1/3rd of the allergies are caused by the residue of laundry detergent in our clothes! go to your search engine and type in fabric softeners and do some research. You will come to a page from the E.P.A. that will list the chemicals in Laundry Detergent, fabric softeners and laundry sheets. It also gives the side effects. This will scare you.
There is only one company that has addressed this problem and solved it. No Laundry detergent, softeners, drier sheets and no hot water. The technology is certified through the space administration. Kills 99.9999% of bacteria, whites come out whiter, colors more vibrant, towels more fluffy, less lint in the drier and does not contaminate the ground water when it drains.
There is another problem that causes allergies and even asthma. Indoor air pollution. Dust, pollen, dander, dust mites droppings, etc... Up to now the "EXPERTS" say dust more. WRONG! Use filters. WRONG! Increase air flow. WRONG! Remove the source. WRONG! We have been told to follow these instructions and watched asthma increase by over 1200%
Don't believe the commercials you see on T.V. These units are very ineffective. You would need many of their units in your home and they would still be doing a poor job.
There is a product on the market that will do what they say and is so effective that the Space administration user their technology that was developed in cooperation with N.A.S.A. It's not cheap but it does what they claim.
Through University studies it has been proven to kill over 99% of staph, strep, e-coli, bacteria, and mold on surfaces. Lastest studies by a University showed 99.99% reduction in the Avian Influenza in just 12 hours on surfaces.
One system will purify the air in a home up to 3,000 square feet. It will also drop the dust, pollen and dander from the air. Over 5 million people have seen the effect of this system. It even purifies the air at the Twin Towers Musium and some units were placed in the Pentagon after 911.
Do more research and tell your doctor you are tired of just treating the symptoms as you watch you childrens health get worse.
