Testing My Drinking Water for PFAS: Cyclopure’s New Test Kit

Testing My Drinking Water for PFAS: Cyclopure's New Test Kit

Do you want to know if your drinking water is safe?

Cyclopure has a home PFAS test kit that can help. It includes everything you need at a very reasonable price. They provide an analytical report for 17 PFAS compounds so you can be sure your drinking water is safe.

You don’t have to worry about the safety of your family anymore with this simple and affordable solution from Cyclopure!

I was concerned about PFAS in my drinking water. So, I bought Cyclopure’s DIY kit and tested my home’s tap water. Continue reading to learn all about their PFAS sample kit and my experience using it.

Read my article – How to Test Your Drinking Water for PFAS for a comprehensive discussion about testing.

Why is PFAS a Concern

PFAS (per- and polyfluoroalkyl substances) are a group of chemicals that have been in use since the 1950s. PFAS compounds are used in products like Teflon, Scotchgard, firefighting foam, and many other common consumer goods. They can be found in drinking water near industrial sites or military bases where these products were manufactured.

The Environmental Protection Agency has detected PFAS in public water supplies around the country because PFOS and PFOA – two types of PFAS – resist breaking down once they enter our environment.

PFAS compounds have been linked with a range of health problems, including cancer and birth defects. They can cause developmental issues in children, reproductive issues for women, and liver damage for anyone who drinks contaminated water over an extended period of time.

Cyclopure’s newly developed test kit will help you determine if your home’s drinking water is contaminated with any type of PFAS compound so you can take action to protect yourself from these harmful chemicals. The DIY test kit arrives with everything you need to collect samples from your home’s water supply and submit them for testing to their lab.

Cyclopure PFAS Water Test Kit Pro

Cyclopure’s PFAS Water Test Kits make high-quality, laboratory water analysis available to consumers. Their system uses the DEXSORB+ adsorbent to provide a water test procedure that does not require the collection and return of actual water samples. As a result, they are able to simplify all elements of the water test experience.

They do all analytical testing at their laboratory using sophisticated mass spectrometers. This allows them to provide part-per-trillion levels of quantification for PFAS.

What is included in the Cyclopure PFAS test kit?

I purchased the PFAS Water Test kit on a Wednesday afternoon. It arrived at my house two days later.

Here are photographs of what is included in the Cyclopure PFAS test kit.

Cyclopure has a very efficient sample kit that fits neatly into a single box. As you can see from the photos, they provide the sample collection cup, detailed sampling instructions, gloves, and a pre-paid shipping label. You use the same box the kit comes in to ship the sample back to them.

Collecting a PFAS water sample

On Monday morning, I collected a water sample from my kitchen sink. The process is really simple.

  1. Wash your hands
  2. Put on the gloves
  3. Turn on the faucet at a low flow
  4. Fill the sample cup to the line
  5. Allow the water to filter through the cartridge (middle photograph)
  6. Put the cap on the jar and place it in the box
  7. Complete the sample information card
  8. Mail the sample to Cyclopure

Start to finish, the entire process took less than 30 minutes.

Cyclopure even has a YouTube video explaining how to use their test kit.


What PFAS compounds does Cyclopure test for?

The Cyclopure Water Test Kit Pro analyzes the drinking water sample for 17 chemicals. These are:

  1. Perfluorobutanoic Acid (PFBA)
  2. Perfluoropentanoic Acid (PFPeA)
  3. Perfluorohexanoic Acid (PFHxA)
  4. Perfluoroheptanoic Acid (PFHpA)
  5. Perfluorooctanoic Acid (PFOA)
  6. Perfluorononanoic Acid (PFNA)
  7. Perfluorodecanoic Acid (PFDA)
  8. Perfluoroundecanoic Acid (PFUnA)
  9. Perfluorododecanoic Acid (PFDoA)
  10. Perfluorotridecanoic Acid (PFTrDA)
  11. Perfluorotetradecanoic Acid (PFTeDA)
  12. Perfluorobutane Sulfonic Acid (PFBS)
  13. Perfluorohexane Sulfonic Acid (PFHxS)
  14. Perfluorooctane Sulfonic Acid (PFOS)
  15. N-Ethyl Perfluorooctane Sulfonamido Acetic Acid (NEtFOSAA)
  16. N-Methyl Perfluorooctane Sulfonamido Acetic Acid (NMeFOSAA)
  17. Hexafluoropropylene Oxide Dimer Acid (HFPO-DA)

This is a very extensive list of compounds for a DIY test kit. Other kits don’t include this many.

PFAS Test Kit Number of PFAS Compounds
SimpleLab – Tap Score 14
National Testing Laboratories – Water Check 3
Freshwater Future – Test and Response Kit 14

What Do the Test Results Mean?

Once you have the full laboratory report with your results, what should you do?

Compare the PFAS results to federal and state standards. If any single compounds exceeds the limit, or if the sum total of PFAS compounds exceeds a threshold, you should be concerned.

What can you do? Drink bottled water or install some type of PFAS treatment system on your drinking water supply. Read my article about how to treat your drinking water.

Health risks of PFAS

A growing number studies have found that there is potential adverse health impact associated with exposure to PFAS chemicals including:

  • cancer
  • liver damage
  • thyroid disease
  • decreased fertility
  • high cholesterol
  • obesity
  • hormone suppression

Further research in pregnant women has shown increased risk for birth defects due to exposure during pregnancy.

Health risks of PFOS

Exposure to PFOS is known or suspected to cause:

  • cardiovascular disease
  • hepatotoxicity
  • immunotoxicity
  • neurotoxicity
  • pulmonary injury
  • renal toxicity
  • reproductive toxicity
  • thyroid disruption

Health risks of PFOA

PFOA health risks include:

  • kidney cancer
  • testicular cancer
  • thyroid disease
  • high cholesterol
  • ulcerative colitis
  • pregnancy-induced hypertension
