* Mold - Severe mold contamination in homes has now been identified with some serious health issues, and many home owners are understandably worried. However, regular screening and prompt control of damp or moisture damaged areas can prevent a serious problem from developing. The Optima monitor will automatically collect air samples that are analyzed at a certified laboratory. A complete report provides an assessment of your home’s efficiency at filtering mold spores from the outdoors, and a first-level assessment of the likelihood of an indoor source of mold. This test is designed by experts to provide the necessary screening information to help keep a home safe from the costly repairs associated with mold infestation.

* Radon - This gas is found naturally in the earth, but can accumulate in below-grade areas and is health related.  

* Total Volatile Organic Compounds (TVOC) - Usually associated with cleaning chemicals, new furnishings and paints.

* Carbon monoxide - A by-product of combustion, the presence of this gas can mean air intakes too near automobiles, or an underventilated furnace or stove.

* Small particles - These are less than 2.5 microns in size and can come from smoke, exhaust (outdoors) and from a dusty building.

* Large particles - These are less than 10 microns in size and can indicate dirty carpeting or construction activities.

* Ozone - This can come from outdoor pollution, or indoors from copy machines and some air cleaners.

* Pollen - A common contributor to many allergy symptoms. We compare outdoor pollen levels to the levels in your home, to assess your home's filtering efficiency.

* Carbon dioxide - An excellent indicator of ventilation rate. Too little ventilation can be uncomfortable and unhealthy, and too much ventilation may be a waste of energy.

* Relative humidity - Comfort related, and extremely important to control in order to minimize mold growth.

* Temperature -Important for comfort, and data collected during unoccupied times can help save energy.
