indoor air qualityIndoor Air Quality is an extremely important aspect of being a homeowner. A not so fun fact; the quality of the air inside the four walls of your home is often worse than the polluted outdoor air itself. The potential sources of air pollution are lurking in nearly every room in your home and possibly interfering with the health of you and your loved ones.

Keeping Pollutants Out: First and foremost, do not allow smoking inside of your home. If you haven’t already, installing a carbon monoxide detector outside the bedrooms is a very effective way to protect you and your family from the invisible and odorless gas that leads to carbon monoxide poisoning. If you do have fuel-burning appliances, you should have a qualified technician inspect the devices at least once a year. Testing for radon and avoiding paints and household cleaners with high levels of chemicals are also best practices for keeping a safe air quality level in your home.

However, when it comes to household irritants such as dust, dander and mold, protocol is different. With proper education and care, keeping out these common allergens is simple to do. Follow these methods of keeping your air as clean as possible.

Ventilate: One of the main reasons that indoor pollution is often so much worse than outdoor air is because the contaminants in the building have nowhere to go. Once they are inside, they become trapped and continuously circulate through the air. Flowing fresh air is important, but also be wary of common outdoor pollutants, especially when pollen counts are high. Keeping thick screens in your windows – that can let cool air in but keep outdoor pollutants out – is key for circulating fresh air. It lets new, clean air in while keeping unclean air out. Fans are also great sources of circulating fresh air. Window fans especially, offer versatile air flow. rdhvac air ventilation

Clean: Regular dusting, vacuuming and overall cleanliness of your home are the best ways to keep dust and dander at bay. If you have pets, be sure to bathe them regularly to reduce the amount of dander released into the air. Combing or brushing is another way to remove excess hair and dead skin cells, but make sure to do this outside so that you aren’t bringing new irritants indoors. rdhvac cleaning

How Did I Get Mold In My Home?

Molds are part of the natural environment and can begin reproducing quite easily. All it takes is for some spores to land on a wet surface and it will begin replicating. Mold can enter through many different passages such as your doorways, vents, windows and central air systems. Mold can even be tracked in from outside when it attaches itself to clothing, bags, or even pets. The mold tends to grow and thrive in places with an abundance of moisture such as leaky roofs and windows, or where there may have been some flooding.

How Serious Of A Problem Is The Mold Potentially?

Some mold is totally harmless – like *cosmetic* black mold or Ophistomoid fungi. These harmless black molds are often found on framing lumber and sometimes plywood. However, Stachybotrys Atra is a toxic mold and notorious mycotoxin producer. Some symptoms of exposure to toxic black mold include dermatitis, sinusitis, conjunctivitis.

Aspergillus is commonly found in house dust or areas of water damage / extreme dampness. Whether you have mold that is relatively harmless or a serious health concern, it all does one thing which is lead to more mold breeding so your situation can always get worse. It’s best to handle any signs of mold as soon as you uncover them.

What To Do When Mold Is Uncovered

The key to mold control is having control over moisture and humidity levels within your home. There’s no practical way to eliminate all mold spores, so the way to control it is to control moisture. Upon finding a mold issue, you must immediately eliminate the source of moisture. If there’s a leak or flooding, the first step is to resolve those issues. Next, reduce indoor humidity so that it rests at a level between 30-60%. Ways you can reduce the humidity are venting bathrooms, using air conditioning systems / de-humidifiers, and using exhaust fans whenever cooking, dishwashing, and cleaning.
