The Water Test Kit is intended for individual or household testing only. This includes using the Kit for tap water, surface water, and well water testing.

Important Notice: Use of the Water Test Kit for research and development purposes, especially with samples containing high PFAS concentrations, can damage our laboratory equipment and disrupt testing operations. Please contact us directly before ordering if you intend to use the Water Test Kit Pro for purposes other than household/well water testing.

Cyclopure tests for 55 PFAS analytes.

No, Cyclopure only tests water sources.

Yes. Please send a photo of the defective cup along with a description of the issue to wtksupport@cyclopure.com.

All components of the Water Test Kit are pre-conditioned and validated to be trace clean, analytical grade for accurate PFAS sampling, including the filter cup, glass fiber membranes, and the DEXSORB®-loaded PFAS extraction disc. No leaching of any other contaminants like plastics occur during the PFAS sampling activities using our WTK.

Our 1.0 ppt LOQ is based on the entire 250 mL water sample passing through the cup. When we calculate the LOQ for a sample, we are taking the mass of PFAS in the lowest standard we use to calibrate our equipment and then dividing that by the amount of sample in liters that went through the cup. When the sample amount changes, the LOQ changes. When we have the ideal amount of 250 mL, we get our usual LOQ of 1.0 ppt. When less sample passes through the cup, we get LOQs that are higher than the ideal sample. Whereas if someone were to pass 500 mL of water through the cup, our LOQ would be lower than the ideal sample.

In addition to PFAS removal, Purefast is also certified by NSF for chlorine (taste and odor) removal.

Purefast does not remove (leaves intact) inorganic ions like fluoride and healthy mineral ions.

Internal testing has shown that our filter offers some lead removal, but this has not yet been certified by a certification agency.

Each Purefast filter comes pre-conditioned for smooth filtration. You may find some moisture or a small amount of water when you open the packaging. This is normal.
