Fiberglass Test Kit
Fiberglass Test Kit – Fiberglass is mostly used as insulation material. It is listed as an irritant, causing potentially serious harmful health issues. The fibers can make their way into your homes living space and hangout in the indoor air when tiny holes occur in your air ducts. These tiny holes expose insulation in the ceilings or walls to forced airflow stir up the the fibers. Also, pieces of a deteriorated duct or insulation within an aging air handler unit frequently get swept through a HVAC system into the living space. Fiberglass particles suspended in the air eventually fall to a surface, usually collecting as a shiny looking dust.
How to Test for Fiberglass in the Air

When we’re asked “how do I test for fiberglass in the air”, we say, now it’s easier than ever with the Fiberglass Test Kit. It’s ideal for screening for the presence and identifying fiberglass fibers and other synthetic and man-made fibers in your home, workplace or other indoor space. Since airborne fiberglass can have serious adverse health effects, and it’s propensity for particles suspended in the air it’s important to test when you suspect it may be present.
Fiberglass Dust in House
Airborne fibers settle on furniture and surfaces, collecting on clothing, bedding, and causing irritation and potentially health problems. Fiberglass can be tested for in the air and settled dust. Your Fiberglass Test Kit uses settled dust as the sampling source. This is the primary testing method for fiberglass is phase contrast microscopy (PCM), which is also the primary method for testing asbestos in the air.
What Does Fiberglass Dust Look Like?
What does fiberglass dust look like? It looks like shimmering dust. It can be suspended in the air or settled on surfaces. Check the top edge of a TV, the unused corner of a desk, or when fiberglass is present in high concentrations it can be seen on cloth surfaces like sofas.
Fiberglass Contamination
If you see shimmering dust, are experiencing eye irritation, rash, or upper raspatory irritation, it’s time to test for fiberglass in your air. Collecting a surface sample is quick and easy and acts as a snapshot of what is present in your indoor environment. Included lab analysis provides world-class results at no additional cost with no hidden fees.
Step-by-Step Fiberglass Contamination Testing
First, read the provided instructions and identify the area of concern. Where do you suspect fiberglass may be present? What location are you noticing your manifestations? Where might fiberglass get in the air? Fiberglass insulation in you air conditioning can degrade get spewed through the system. Do you suspect this may be happening?
Next, use the Bio-Scan to collect your sample. After collecting the sample, re-seal the Bio-Scan and complete the chain-of-custody. Place the sample in its case into the provided postage-paid envelope.
Then, your sample is analyzed by an accredited laboratory to provide their accurate and detailed analysis. That’s how to test for fiberglass in air, simply and cost-effectively.
Lab Analysis Included, No Hidden Fees.
WTI laboratory services will provide a final report included in the cost of the Fiberglass Screen Check. Your lab report includes the identification of the presence of and the concentration levels of any fiberglass or other fibers identified. Measurements are reported in Counts/cm², and will have guidelines for what is considered to be a normal manageable level, as compared to the total level of each pollutant found in your sample.
Test Kit Lab Results Sent to You
Once the lab receives your sample for analysis, your lab report will be available in PDF format and emailed to you within 3-5 business days. Accredited lab analysis is included in the cost if the Fiberglass Test Kit, there are no hidden fees.
Common Signs of Fiberglass in the Air and Environment
- Shimmering dust on surfaces
- Itchiness
- Eye irritation
- Coughing
- Scratchy throat
- Sneezing
- Respiratory issues
- Sinus headache
Exposure to Airborne Fiberglass
When non-occupational fiberglass exposure occurs in your home, office, or school, it’s most frequently due to the condition of your home’s ductwork and air handler unit. As a furnace or air conditioner ages, the components can breakdown. Pests can damage ductwork in the attic by chewing holes or nesting. When this occurs, the integrity of the system can be compromised. Insulation from the duct linings, and from the attic, as well as other debris can now enter the airflow of the system. That debris and insulation can then be distributed throughout the air of the house.
Breathing in Fiberglass Particles
The next most common way fiberglass gets into the air is through the movement of fiberglass-containing materials within and airflow within the building or room. If work is being done on your home for example, there is a high probability that insulating material will be used, the materials can shed fibers into the living area of the home.
Once fiberglass is installed in buildings and is maintained appropriately (aging materials replaced, pest-damage prevented and repaired), exposure to fiberglass and breathing in fiberglass particles is unlikely. The best way to avoid fiberglass particle exposure is to avoid damaging, disturbing or contacting insulation material in attics, walls, ductwork, and HVAC and furnace systems.
Health Effects of Fiberglass
The health effects of fiberglass primarily consist of skin and eye irritation. When it touches the skin, fiberglass can cause a skin rash also know as contact dermatitis. Eye irritation, redness and itchiness are common. Exposure and inhalation of fiberglass particles can also cause upper respiratory irritation which causes sore throats and noses.
vollballer79 –
My eyes were getting very irritated at night. I purchased this test and it was instrumental in determining my reaction to fiberglass in my home. Since using the test I have been able to take the proper steps. Without this test I would have never know what was the problem with my indoor air.
