• Radon

Is a naturally occurring gaseous element that escapes from granite as other natural elements like uranium break down. Once it is a gas it's inhaled and after a short while it breaks down into Polodium, Bismuth and Lead where it releases radiation, mutating your cells and causing cancer. The EPA's Citizens Guide to Radon can be found here.

Radon is second leading cause of Lung Cancer in America.


Identifiable Traits: Colorless, Odorless, Tasteless
Method of Detection: Air Sample Test

  • Formaldehyde

Just a simple corrosive, colorless carcinogen.


Identifiable Traits: Colorless, Pungent Odor, 
Method of Detection: Air Sample Test

  • Low Level CO Exposure

Did you know most CO Detectors only alert you at levels of 35 ppm, but are hazardous to your health at 7 and 8 ppm?

Identifiable Traits: Colorless, Odorless, Tasteless
Method of Detection: Carbon Monoxide Detector (of which can detect to 0)

  • High Level CO2 Exposure

Identifiable Traits: Colorless, Odorless, Tasteless
Method of Detection: CO2 Monitor

  • Mold Spores

Identifiable Traits: Visible Growth on walls, Mild to Extreme Odor, Tasteless
Method of Detection: Air Sample Test if not clearly visible

  • Mildew

Identifiable Traits: Surface fungi that can easily be identified as a patch of gray or even white fungus that is lying on the surface of a moist area.

Method of Detection: Air Sample Test if not clearly visible

  • Dust

Identifiable Traits: A visible particulate matter comprised of a variety of: smoke, pet dander, dust mites and bacteria and viruses.

Method of Detection: Visible on surfaces and in rays of light

  • Odors

Identifiable Traits: Pungent, may be able to be tasted

Method of Detection: Whether it be you after mowing the lawn, the cat's litter box or something in the fridge that's gone bad, initially odors should be fairly easy to detect.

  • Pollen

Identifiable Traits: Pollen is a fine to coarse powdery substance, 

Method of Detection: Pollen may be detected by those with allergies, an air sample test, or visible buildup -normally around puddles, bird baths and other small collections of water.

  • Pet Dander

Identifiable Traits: Pet dander is a protein found in the very tiny particles of skin that had been shed from animals with fur or feathers. In addition, the protein is also found in the urine and saliva of these animals as well.

Method of Detection: Allergic reaction, hair that has been shed, 

  • Chemical Cleaners & Aerosols

Identifiable Traits: Strong chemical smells, residue, can be tasted in the air

Method of Detection: If someone's house is "very clean" it's likely they use cleaning products to achieve that. A mixture of 50% water and 50% white vinegar is also an effective, and non-toxic, cleaner as well.

  • Smoke

Identifiable Traits: Due to difference in temperature between the studs or screws and the interior wall smoke -like moisture- attracts to these points and are commonly visible. Other places where the carbon in the smoke builds up is on the ceiling above the device that is using combustion often. Be it candles, a wood stove or pellet stove or a propane stove or fireplace.

Method of Detection: Generally speaking, smoke is fairly easy to smell or see. Small amounts from candles however, may be harder to detect without equipment.
