Easy to use and mail-in the sample. Report came promptly and was credible. I appreciate that the report said we do not have PFAS in our water, since they could make money selling us filters, etc.

The process was so easy from collecting the sample to sending it back with included UPS shipping label. They say results will come within 10 days and mine came in 9.

Really excited to be using the DEXSORB PFAS test kits. We have done thousands of PFAS tests and this test kit is going to be a game changer for the industry.

Reasonably priced PFAS test The test is easy to handle, and the results came in pretty fast. No way to calibrate the results, since we didn't do a second equivalent test, but we expect they were largely accurate. The cost is several times lower than the local people who do the same testing, albeit not "certified" by whoever does that.

Easy product to utilize. Simple and clear process. Fairly quick results (less than 10 bus days.) Very nice person called me when they received my sample back and they had a few questions.
