KKMOON Portable Air Quality Detector Indoor/Outdoor Digital PM2.5 Gas Monitor LCD TVOC Tester Instrument Meter Air Analyzers with Rechargeable Battery

We have allergies, mold, dust, viruses, and maybe radon—every time someone in our family gets sick, it’s hard for us to figure out what’s going on. With this device, I found dangerous emissions, or chemicals, or items that are too old, which are not needed in the environment. I think what I want to say is that I am worried, and after testing the environment, I feel relieved. I hope this does not sound like these false comments, because I am impressed with the technique and the entire explanation of this manual (which reminds me that it was a mistake to give up my science major).

This device is so useful! Make sure you follow the instructions; before you calibrate the device in real fresh air, let the monitor exhaust for the time in the manual state. Test with doors and windows closed. In addition, before testing, make sure that your building has been closed for a period of time. Do not test during or immediately after cooking, as this will cause your TVOC readings to be higher. If you do not follow these instructions correctly, you will get inaccurate readings. This monitor proves that we do have the problem of high formaldehyde content and high TVOC content in indoor air, which makes us more and more sick. The cost of conducting an aerial test with a disaster relief company we verified will exceed $500! On the other hand, the agents said that their monitor was similar to this one. After testing our air, we researched many air purifiers and decided to buy a Molekule air purifier, which proved to be a purchase that we are very grateful for, so we purchased the second one about a month later. Preliminary tests conducted with this air quality monitor showed that our numbers are very high and are red, which indicates that the air pollution is serious and toxic. In addition, we have an unbearable smell, which will not disappear, even though we keep opening the windows for a period of time to ventilate the house. After running the purifier for a few days, we tested it again. This time it is green, indicating that the content of formaldehyde (HCHO) and total volatile air compounds (TVOC) in the fresh air is much lower. After using Molekule, the terrible smell disappeared! Then we can go home. Don't be fooled into buying more expensive indoor air quality monitors! This really works!

I don't understand why some people say they have a hard time figuring out how to use it! It comes with quick instructions, and I also received an email link directly to the complete user manual. A piece of cake! I like to take it around the house to see how I deal with Aspergillus in the damp basement, because I patched a loophole there, and in the attic, I was worried that there would be volatile organic compounds from the spray foam insulation , Just for fun, in the kitchen, when VOCs pass through the roof when we cook. But really, for a layman who is allergic and anxious to dust, mold and other terrible garbage in the air, this is a perfect DIY thing that can be used to measure, appease or inspire action!

The air quality monitor works very well-I wish I knew it sooner. I used this on a new house I bought in 2018. Since moving into this house, my wife and I have suffered from headaches and other reactions. Various products used in new buildings have exhaust. We have been able to accurately determine the areas with high exhaust volume and ventilate these areas so that the readings fall to a good air range. We already feel better. Thank you for providing this product.

My 6-year-old daughter always wakes up in the same morning with a bad cough. The discussion between my wife and I considered this to be an environmental issue because it started shortly after we started using central outdoor natural gas heating. She has used a humidifier to sleep to help keep moisture in the air. We think that there may be gas or exhaust gas passing through the exhaust port. I searched the Internet for a reasonable and user-friendly air quality monitor and found this. I am not an expert, but it seems easy to operate and set up. Although the accompanying user manual is a bit lacking in details, it is enough to get you up and running. Fully charge, calibrate, and be ready to see what causes my daughter to wake up and cough at 3am every day. After letting it run all night, I immediately checked it the next morning. There is nothing to see here except the fresh green air. Except for some dust, there are no other pollutants. I knew I must be doing something wrong, so I called an HVAC/Air Quality Professional. He came to check up and down the house. He also found nothing. I showed him the air quality monitor I used, and he was happy to tell me that I have a good monitor to use. After reading the log, he said that this coincided with his findings. We are still looking for the cause of the cough, but we know that thanks to my purchase of this air quality monitor from EG EVERHOLD LLC, our air is clean and I have a great tool to help keep it that way! No problems, no complaints, either way I am glad I bought one!
