Air Formaldehyde (HCHO) DIY Test kit - Know What's in The Air That Surrounds You (Pack of 5)

I have not submitted a review on Amazon before but I am so impressed I really need to do that now.I ordered two of these kits and they arrived on time, in good shape. There was a date of 03/19/2018 printed on the plastic overwrap on each package. I assumed, like many products, that this was an expiration date. Because formaldehyde is a very serious issue, and a known carcinogen, I was dismayed that I received what I thought was expired products. I submitted a question to the seller via Amazon and was satisfied and impressed with their immediate response. Even though the package does have a statement about “Production date: see package” this is ambiguous particularly for something this important. The seller confirmed that the date stamped on the package is the production date, not the expiration date. So I am able to use the kits with confidence regarding the product viability. In addition, the most critical color range is on the lower end particularly around the “safe” threshold of 0.10. The colors on the low end are very light and similar. So, I exchanged additional emails with the seller regarding possible improvements such as changes to the sample container and color card. They were very open to feedback and as before, we exchanged a series of emails about possible improvements.I actually trim the excess white off the color card and lay the color strip across the top of the powder box to take the reading. This enables me to get the color card as close to the liquid without touching the liquid inside the powder box. I’ve included an image of two samples side-by-side along with the color swatches. I found it difficult to discern the score for the sample on the left and sent an email to the seller. It’s not in the yellow/brown range (0.01), and it’s definitely not blue (0.15). To me it looks like it’s in the green region but I could not distinguish between the 0.08 and the 0.10 score (safe threshold). I asked the seller if they would tell me what they thought and they quickly replied saying they consider this to be a 0.09. This makes sense to me and I agree.This seller met and went above and beyond my expectations. It was very clear that the seller has thought through a variety of options regarding the ease of use of this product for a person at home, as well as the ability of someone to properly use and interpret the results. They are very open to improvements and are currently investigating improvements in the color card for future versions of the test kit.I originally gave this 3 stars due to the ambiguity when scoring the sample at low levels. But, I have been repeatedly impressed with this seller’s attention to detail, their quick responsiveness, and thoughtful replies in our somewhat lengthy email exchanges. While I do think photographic examples of control samples would help reduce ambiguity, the seller explained the difficulties and cost associated with this approach. Based on my experience with the kit and the seller, and given the low cost, I do think this is a 5 star product and provider who has a genuine interest in the quality, safety, ease of use, and ongoing improvement of this product.

Was easy to use and was acurate.

Only two of the three kits in the pack had the developing chemicals. Luckily I had only planned to test two rooms. Otherwise relatively easy to use.

The seal on the absorbent cannister was broken with signs of moisture inside. Most of the powder had leaked out of the cannister. The color developer liquid bottle had brown stains at the top. The other reviews mentioning old and/or improperly stored tests are correct.

I had order 3 boxes of it, but one of the brown tube is empty or dry. Therefore I just can use two of it.

The cup that it comes with is what you put it in, the instructions make it seem like it wants something else, but the cup has powder that will be used, other than that, it is accurate to my monitors as this monitor was the only one I've tested that does not say I am dying, and this test shows it.This takes around 45min or 75min based on the examples.

TBH it's hard to tell the accuracy without any reference. Mine came back with within healthy range so I'll not contact any 3rd part to do the test. I'd prefer to believe it is roughly accurate. :-) It's pretty easy to use. No complaint.

I bought a desk in March for my home office (after the stay at home guidance went into effect) and realized, over a period of light use, that the smell from the desk was irritating my airway, causing headaches and dizziness. My husband wasn't bothered by it at all (he also didn't spend as much time in there) so I kept ignoring the 'symptoms'. Two of my plants in the same room ended up dying over a period of weeks so I started researching and learned that formaldehyde could be a culprit. The first test kit I ordered had a punctured cylinder and the powder had leaked into the box so there wasn't much to be used. I tried it anyway and the results came out normal but I wasn't convinced. Upon contacting Air Steward, they promptly sent me another kit which had the cylinder in tact. The results from this test kit are attached and I've included a comparison to show that the photo to show the color difference.Really impressed with Air Steward and their customer service!Am on the phone with the company from where I ordered the desk to see if they will take it back and will definitely take the Prop 65 warnings more seriously now when buying additional items for the home. Don't know how much damage the exposure to these levels of formaldehyde has done but hoping this review will alert others to the harmful effects of chemically treated furniture as well.

Easy to use kit! Revealed we had no formaldehyde but did the job.

2 of the 3 kits were not useable as the solution had leaked out of the containers. Incredibly disappointing. Will be returning.

Worked very well!

Two tests arrived in good condition, and worked well with clear results. The other two arrived damaged - the first one had an issue with the powder in the container - it appeared to have been wet previously and the test did not work; for the second, the absorbent in the brown bottle had leaked out and I could not complete the test. I guess take your chances and order a spare or two. I am returning the defective tests I received.
