Humidity And Mold Build-up

Indoor air pollution is a serious issue among home owners. The level of contaminants indoor is said to be quite a few times higher than outside. There are many sources for these contaminants to find their way into your living space. They are household products, building materials, formaldehyde, and/or respirable particles. Molds are one of the airborne microorganisms that badly affect the quality of indoor air. These are part of the natural environment and can be found everywhere indoors and outdoors. They are not a problem unless they start breeding and growing indoor. They cause serious respiratory issues and allergies to people living in the house. The best way to control mold is control moisture. They need moisture to grow. No moisture no molds!

Molds produce spores. These can be called tiny encased "seeds," that drift in the air. A contaminated house will have millions of these suspending in each cubic foot of air. The main source of molds in the house is the HVAC and its duct work. Ducts often turn leaky with time. Sometimes the joints are not tightened enough or they loosen up. Moisture trickles though these loopholes. The air that pass through the ducts bring with it host of dirt particle and debris. With these duct gets infested with matted layer of dust. Moisture also settles in. The result is a fertile ground for molds to breed and grow. Some molds are visible. You can identify them through it its discoloration and odor. You will see the discoloration at the vents that is a sign enough of active mold growth inside the ducts. A musty odor would also come out from the HCVAC.

Get a dehumidifier

If you live in humid climate, then you should get a dehumidifier fitted in the house. It will pull excess humidity from the air that will restrict mold growth.

Buy a powerful air filter

These days there are air purifiers that can combat the multiplying presence of mold. They are equipped with the HEPA air filter that can trap microscopic particles. These are very efficient and capture a minimum of 99.97% of pollutants at 0.3 microns. Mold spores range between one and five microns and will easily fall prey to the HEPA filters. You can fit these filters in spaces which are prone to molds such as basements, bathrooms, kitchens, and rooms with upholstered furniture. Replace the filters at regular interval.

Get the duct work cleaned

Get your duct work professionally cleaned once in every three to five years. The professional will come with shop vacs and motorized brushes and remove a fair amount of dirt with these tools. They will also clean certain HVAC parts which are prone to get dirty. If they are not able snake to remote corners of the duct, they may use fiber optic camera feeds to see the level of gunk in the distant interiors. They may make incisions at these points to remove harmful build-up. These cuts will be restored once the job is accomplished. However molds cannot be terminated just by cleaning. You cleaner may recommend using biocides to terminate their growth. But spraying biocides in the ducts can cause health hazards. Do enough research before you opt for them. Always go for EPA approved biocide. Ensure that they are used according to the instructions on the label. Also remember any black patch in the duct is not a sign of mold. You should send a portion of it on a sticky tape to microbiological laboratory to confirm that the black patches in your duct are mold indeed.
