Our Number One Goal Is To Provide Accurate Testing And Cleanup Directions With Excellent Customer Service.

American Air Testing is a small family business comprised of indoor environmental professionals who are qualified by experience and skill of over 20 years in the industry as well as continuing education, training, and certifications. 

Our team is able to perform assessments of the condition of structures, systems, and contents at a job site. Based upon our client’s concerns, the history of the building, and what we encounter onsite, we develop a sampling strategy that is discussed with our client prior to collecting any samples. Once samples are collected, they are submitted to a certified laboratory. Laboratory results are reviewed and interpreted along with the information gathered through the onsite inspection. If a hazard is found, then an abatement/remediation protocol is produced outlining any applicable next steps for the project. The goal is to return the job site to a healthy indoor environment.

With current industry standard knowledge and equipment, we provide consulting and testing of indoor air contamination for a wide variety of contaminants.

Everyone responds differently to mold. Mold becomes “toxic” when the spore count level in the inside ambient air is greater than outside. Some people are very sensitive, while others don’t respond to high levels of mold. High levels of toxic mold spores have been linked to asthma and other respiratory issues.  Please consult your physician or health professional for personal guidance.

Your physician may want to run allergen tests before giving you guidance. If you are concerned that you have been exposed inside your home or office, we recommend a Peace of Mind Mold Inspection. 

If no elevated levels of mold are found inside your home or office, your allergic reaction may be caused by another allergen

The laws around asbestos sampling are complicated. Basically, we need a minimum of 3 samples for each material identified on the EPA asbestos list. The sampling number may become higher depending on the amount of removal needed. More info here

First wash and thoroughly dry the stuffed toy. If it is not suitable for laundry, the toy should be removed and replaced.

Once the toy is dry, gently remove stitching that will allow removal of all stuffing. Discard all stuffing inside a plastic bag that is tied or sealed. Wear a mask and gloves while doing this work. Is possible do this work outside in a mild breeze.

Resuff the toy with new stuffing and see the smile on your child’s face!

Formaldehyde is used in building materials, primarily as an additive to wood glue because it requires a low-cure temperature and is resistant to abrasion.  Formaldehyde is a carcinogen.  Formaldehyde was listed by the State of California  in 1988 as a chemical that causes cancer. There is a new bill under current review that will ban formaldehyde in beauty products, especially baby shampoo. Formaldehyde off-gasses quickly to the point where it is not smelled by most, but the chemical still remains in the air.
