The price includes the vapor sampler, return shipping, laboratory analysis, and a final report detailing the formaldehyde concentration along with any other aldehydes detected. If high levels are detected, we provide detailed suggestions to help lower these levels.
This sampler is especially useful for evaluating aldehydes in indoor air, including home indoor air quality concerns related to formaldehyde and other aldehydes. These compounds can be released from building materials, furniture, flooring, cabinetry, adhesives, coatings, and other indoor sources, so testing can help determine whether elevated concentrations are present and whether corrective actions may be needed. Please see our aldehydes in indoor air page for details, and our blog explaining why it is important to measure more than just formaldehyde.
We use EPA TO-11A to measure formaldehyde and related aldehydes. This method provides highly accurate measurements for formaldehyde and other aldehydes in air.
To use the sampler, place it in a central location and expose it for 24 hours. Please note that all aldehyde samplers are sensitive to heat, so we recommend storing and shipping them refrigerated, especially during the summer months. Exposure to high temperatures can cause decomposition of the sampling media, leading to background signals that may result in false positives.
Our samplers include a built-in media blank to help measure potential decomposition. This allows us to determine if degradation has occurred and apply corrections to our analysis. We are actively working on improving this aspect, so stay tuned for updates. In the meantime, please avoid storing or transporting samplers in hot environments, such as inside a car during summer.
