Hi there! New member here, and have a possibly unique question for you. We had a black mastic asbestos abatement done at our home. It was completely botched because the company had someone doing this who didn’t know what they were doing. They “couldn’t” remove all of the mastic, they let chemicals sit for days trying to soften it, and they then applied encapsulant before everything was clean and dry…twice. This happened at the beginning of February. The company has been trying to fix things, including air quality ever since. VOC test showed off the charts high in April. Would any of these residential monitors be able to be calibrated to establish a baseline, and let us know if the VOC’s increase or decrease as more solutions are tried? Thank you!
Hi @Django14,
Thanks for joining and great question!
Unfortunately, consumer-grade VOC monitoring is a complex topic (just have a look at this thread!): Air Quality Monitors for VOCs
Most devices use relative indexes, and those that don’t show ‘absolute’ values that usually aren’t very accurate due to cross-sensitivities. You could try a device with an adjustable baseline (like AirGradient), but any device would need to be regularly taken outside to establish a meaningful baseline.
You could get some insight from a consumer-grade device, but I would definitely still recommend proper tests in your case.
