Humidity-Sensing Fans Prevents Mold or Mildew Build-Up
There is no practical way to eliminate all mold and mold spores in your home. According to the EPA, the way to control indoor mold growth is to control humidity and moisture.
By reducing indoor humidity (to 30-60%) you can decrease mold growth by venting bathrooms, dryers, and other moisture-generating sources to the outside. Using air conditioners and de-humidifiers, increasing ventilation and using exhaust fans whenever cooking, dishwashing, and cleaning also help in humidity build-up.
Humidity-sensing fans make a lot of sense for homeowners and especially rental property owners. With standard fans, you are relying on the user to turn the fan on or off. Too many times the fan is not turned on, and proper ventilation does not happen. This can lead to problems such as mold or mildew, and poor indoor air quality in the home.
If you only remember to turn on the fan after you've stepped into the shower, or if the kids can't be trusted to remember at all, this QTXE110S Ultra Silent humidity-sensing fan from Broan offers a convenient solution. It also works well for busy families that need to leave the house before all the humidity is properly vented. Equipped with Broan's exclusive Sensaire technology, the fan detects when steam and humidity levels quickly increase at the ceiling, then it turns on automatically to help return the room to normal humidity levels, which in turn helps prevent mold and other cosmetic and structural problems associated with excess moisture. Even more, it turns off automatically when the job is done (auto shut-off time is adjustable from 5 to 60 minutes).
Broan Sensaire technology is a hands-free solution to fighting excess humidity and possible mold problems. It detects rapid increases in moisture levels at the ceiling, where steam do humidity naturally rise, and automatically turns the fan on. With a fan this quiet, we included automatic shutoff to save worry, and money. Broan Sensaire technology is a perfect solution for high traffic bathrooms, the kids' bathroom, or for anyone who leaves the house before humidity is properly vented. Detects a rapid rise in humidity.
Imagine 40 pounds of dust spread throughout your home, pushed into the air for you and your family to breathe up to seven times a day, via your heating and cooling system. Pretty gross thought, right? Well, unfortunately there is a high possibility that this is the exact situation in your house right now .
Through normal occupation in a home, a sizeable amount of contaminants, such as dander, dust and chemicals, are generated. In a typical six-room home, up to 40 pounds of dust is created annually through everyday living, according to NADCA: The HVAC Inspection, Maintenance and Restoration Association. These contaminants are pulled into the HVAC system and re-circulated five to seven times per day, on average.
Your heating and cooling system can be considered the lungs of your home, taking in air and breathing it out. Generally, the cleaner the lungs, the cleaner the air in your home. That's why it's important to get a quality HVAC cleaning done on a regular basis. But beware, not everyone claiming to be an HVAC cleaning professional can do the job the right way.
There are some important things you need to consider so you avoid companies with unethical business practices or bad cleaning techniques: Read more...
A home air check test will give you a total assessment of the indoor air you breathe in every day. It is available to the home market, and gives you an affordable, comprehensive air quality audit of the airborne chemicals in your home...such as volatile organic compounds (VOCs) and mold VOCs (the chemicals emitted from actively growing mold).
Indoor Air Quality Test | Health Reasons You Should Test Your Home
1. Elevated VOC levels in the home can lead to both short-term and long-term health issues. The U.S. Green Building Council's recommended healthy building level is 500 ng/L. In research however, data from hundreds of homes measured by homeowners show the median value is 1,200 ng/L, more than twice the recommended level.
2. High VOC levels can trigger asthma attacks in the more than 20 million US adults and children who have the disease. Asthma is also the most prevalent chronic illness among children. Therefore, finding high VOC levels and their sources can be beneficial to homeowners and tenants.
3. Babies, young kids, pregnant women, seniors, and people with respiratory or cardiovascular ailments can be more vulnerable to indoor air pollution. If your family is made up of any of these groups of people, then an air quality assessment would be highly recommended.
4. Asthma prevalence and severity continue to rise and are at all-time high levels. At the same time, outdoor air pollution is declining. It's a well-known fact that most people spend about 90% of their time indoors. Therefore, many experts suggest there is a strong association with the increase in asthma illnesses and indoor air quality.
5. Common household and personal care products contain VOCs and off-gas continuously, leaving home occupants constantly exposed to airborne chemicals. A home indoor air quality test can predict the sources of VOC contamination.
6. Many newer, more energy-efficient homes do not "breathe" correctly. A home indoor air quality test can potentially discover HVAC issues before they become more of a problem.
7. Carpeting, vinyl and laminate flooring, cabinets, countertops, and other similar building materials use adhesives that “off-gas” continuously over time, even for years. Many of these materials are manufactured using hazardous chemicals, some that can even cause cancer. Testing for harmful toxins that could be lurking within the framework of the house would be a good idea.
8. Soil gas from environmental contamination can seep into the basement similar to radon. A home air check test can spot this contamination.
Lawsuits are becoming more common in the hospitality industry due to the potential hazardous health effects of employees and patrons exposure to secondhand tobacco smoke.
Recently, a group of ventilation experts hired by ACGIH and OSHA made a discovery that dilution ventilation, which is something used in just about every mechanically ventilated building does not control secondhand smoke in the hospitality industry, which would include nightclubs, restaurants, bars, casinos, and so on. With this finding, it quickly became apparent that a new and more advanced form of technology was needed.
Although many states now have strict rules about smoking in restaurants, other hospitality industries still have unlimited smoking, which means non-smokers either cannot visit those places or they have to accept that they are placing their health at risk by going. Not only is secondhand smoke a serious problem, but when you consider that proper ventilation is not routinely enforced nor are all codes followed, it is no wonder that people become sick.
The problem is that even with special sections designated for non-smokers, the smoke still flows in the air breathed meaning the risk of lung cancer, respiratory infection, asthma, and other major illnesses is still very real.
The air nicotine levels for bars, restaurants, casinos, smoking lounges, bowling alleys, and nightclubs is still a huge problem. In fact, even with improved ventilation and new means of control technology, it is still estimated that the risk of lung cancer and heart disease for workers in the hospitality industry is between 15% and 25% MORE than the significant risk level established by OSHA.
Unfortunately, for the individuals working in the hospitality industry, a large majority are stuck. Within this industry, you often find workers that do not have a college degree, single parents that need flexible hours, college students, and other individuals that are not afraid of hard work but unable to work in other industries. For these people, while they love the work they do, they have no choice but to go to work every day and breathe in secondhand smoke.
The good news is that many of these hospitality workers are now fighting back through lawsuits or lobbying to change laws. While there have been a number of unsuccessful lawsuits over the years filed by smokers against tobacco companies, today we see more and more non-smokers standing up for their rights to enjoy public places without having to put them or their family at health risk.
One such lawsuit was filed that soon became the “mother of all tobacco lawsuits”. With this case, the trial began on September 21 in Washington, DC and after five years, $135 million dollars of public money was spent just in gathering evidence. This lawsuit consisted of the United States Government facing off with the big tobacco companies. However, smaller lawsuits have been cropping up more and more in the past few years from individuals tired of breathing secondhand smoke.
For example, in 1998, there were lawsuits filed from 46 of the states against tobacco companies, resulting in a payout of more than $256 billion. Because more people are speaking out, the U.S. government is paying attention. In fact, governmental lawyers are now supporting non-smokers, trying to prove that tobacco companies committed fraudulent acts by deceiving the public for the past 50 years about the dangers of smoking, let alone secondhand smoke.
The challenge with secondhand smoke and the hospitality industry is that lawyers for major tobacco companies say intent to mislead or defraud non-smokers sets the bar way too high. Although this challenge is massive and will take many years to resolve, what it does show is that workers in the hospitality industry, as well as people that enjoy frequenting these types of establishes are in fact tired of having to breathe polluted air.
In addition to government backing, many organizations have been formed to educate the public about secondhand smoke and to change the rules for public smoking. The new bans that are going into effect here in the United States along with other countries around the globe include tobacco advertising, sponsorship, and promotion. This includes changing the packaging and labeling on tobacco products, rewording deceptive terminology, establishing smoke-free areas within the hospitality industry, fighting tobacco smuggling, increasing tobacco taxes, promoting public health, and other measures to protect non-smokers in the hospitality industry.

In most houses, externally vented central furnaces fueled with natural gas pose no indoor pollution problem when properly designed and maintained. However, if there is a faulty exhaust system (like a blocked flue), or if there are cracks and leaks in the pipes or improper adjustment of the burner, or if there is lower air pressure indoors than outside, the furnace can create serious indoor air pollution. If you suspect incomplete combustion or leakage in a gas furnace or other appliance, call your local utility company or a heating contractor who can test carbon monoxide levels. Here are some things you can do to ensure gas furnace safety:
If you have an older gas furnace, install a supplementary induced-draft fan that reduces the possibility of backdrafting. There are also automatic shutoff devices that turn off the furnace if it begins to backdraft. You may want to think about buying a new, energy-efficient furnace.
If you're installing a new gas furnace, choose one of the more efficient models that uses an induced-draft system or brings outside air directly into the combustion chamber.
Have your furnace inspected and your chimney cleared of debris in the fall before starting up the heating system. Among things to look for are holes or open joints in the metal pipe and such obstructions as birds' nests, heavy accumulations of soot, or even pieces of masonry that have broken loose in the chimney flue.
Have a separate flue for each combustion device. Many chimneys are partially blocked because the pipe from a wood or coal stove has been brought into the same flue that vents the furnace. This dangerous arrangement could send gases from both furnace and stove into the house.
