I've also suffered from indoor allergies and Sick Building Syndrome on several occasions in my life. I am passionate about sharing my expertise and lessons learned in hopes that it helps you to live a longer, happier, and healthier life. The many pages of this site share my best insider's tips and proven strategies guaranteed to help you cost-effectively reduce your family's exposure to indoor air pollutants (such as mold and toxic chemical gases), as well as help you avoid many other allergy triggers and hidden household dangers.Homes are complex systems with many interacting variables.

So potential causes of indoor allergies and home injuries are often not obvious or easy to predict or eliminate. But by applying these basic tips you can greatly reduce much of the risk... Indoor Air Quality Testing is a good starting point because it will help you to identify possible sources of indoor air pollutants so you can remove or control them. Some examples of common airborne hazards difficult to diagnose unless you test for them are: Deadly Radon Gas (the 2nd leading cause of Lung Cancer deaths!), Formaldehyde Gas (from household chemical products, adhesives, and engineered wood products)...Volatile Organic Compounds (off-gassing from carpeting, furniture, gasoline, ect.)...hidden colonies of actively growing toxic black mold...or particle / fume hazards (such as from third-hand or second-hand cigarette smoke and left-over residues).Source Control / Removal of indoor air pollution causes and hazardous materials (such as lead, mercury, formaldehyde, and asbestos sources).

My extensive household chemical encyclopedia will help identify where in your home many of these hazardous materials may be found, including healthy home advice for each room of your home.Ventilation with fresh outside air to dilute indoor air pollutants and increase oxygen levels. Efficient Air Purification System consisting of the very best HEPA room air purifiers and HVAC air duct filters to capture tiny particles AND chemical gases (but always avoid Ozone Emitting Air Cleaners!)air purifier made in the usaProper Exhaust of toxic combustion equipment gases (such as deadly Carbon Monoxide Gas) and lung damaging particles (such as smoke from wood-burning stoves). where to buy air purifier in shanghaiAlso ventilation fans and ducts to exhaust fumes, moisture, or particles to outside the home, for example while cooking, operating clothes dryer, or while steaming up the bathroom when showering.cleaning airbrush after use

Our ancestors lived in well-ventilated (drafty) homes built mostly of inert all-natural materials, such as locally quarried stone and hand-cut timber.I guess you could say Green building was the norm a hundred years ago. There were far less chemical toxins inside homes back then. But climate control was also more difficult.Contrast that to modern times, when indoor air pollution has become a man-made global epidemic.Our homes are exponentially more air-tight and energy-efficient. But this means they also have the tendency to accumulate off-gassing toxins from the many chemical-based products they are constructed from and filled with.The costs and benefits of the past have been inverted in today's homes.

We have gained energy efficiency, but lost air quality because of all the accumulating by-products from our "better living through modern chemistry".But green building is once again becoming the norm and indoor air quality has become the main focus of creating healthy home environments. No wonder air purifier sales have exploded upwards over the last decade. But is air purification enough? As you can see by the image above, an effective healthy home strategy is not about focusing on one magic bullet, such as an air purification system and room air cleaners as a catch all.Don't get me wrong. An efficient HEPA air purifier able to capture the tiniest of particles and toxic chemical gases found in most homes IS important and I'll definitely help you find the best purifiers.But source control and prevention of biological contaminants and chemical toxins should be the priority because no room air cleaner will filter out 100% of indoor air pollutants in any given volume of air, nor will it be able to always intercept pollutants before an occupant inhales them.

It is always best to control the conditions and sources before hazards result, as opposed to just treating the symptoms after there is already a problem.For example, many homeowners and tenants think that a room air cleaner will greatly reduce or eliminate the potential health issues caused by significant amounts of second-hand cigarette smoke indoors. Nothing could be further from the truth.Sources of the cigarette smoke should be totally removed from inside first and foremost because not even the best air purifier filters can keep up with high volumes of damaging smoke particles and toxic gases (such as Carbon Monoxide and Benzene) that indoor smoking typically causes.I stress source control above all else throughout this site. Air cleaners are more of a stop-gap measure not to be solely relied upon to completely fix indoor air quality problems.Another major take-away from this site is that the majority of your "Human Footprint" and your indoor air quality, results directly from what goes into and comes out of your humble abode.
