Features:

  • MULTIFUNCTIONAL & SCIENTIFIC – This indoor air quality monitor accurately assesses temperature (in C/F), humidity level, and multiple measures of air quality including concentrations of formaldehyde, total natural & synthetic volatile organic compounds causing most odors (TVOC), and fine particulate dust matter (PM2.5/PM1.0/PM10) which travel deeply into the respiratory tract, reaching the lung alveoli.
  • PORTABLE TESTING – Spot check indoor air quality or leave device on for continuous monitoring. Built-in stand allows air monitor to be placed unattended anywhere. This easy-to-carry device can help monitor air quality at home, in the car, and in hotel rooms. The lithium battery provides portable power when DC 5V micro USB charging is not available. Information is displayed on a clear 2.8” 320 x 240 pixel color LCD display.
  • ADVANCED FAN & SENSORS – This air quality monitor has a built-in fan to quickly draw in ambient air to allow REAL-TIME measurements. It incorporates a laser sensor to measure levels of dust particles and has a second electrochemical semiconductor sensor to measure formaldehyde and natural/synthetic organic compound levels. Air monitor also auto calibrates in fresh air.
  • HEALTHY HOME? – Is your family suffering from sick building syndrome? This air quality tester detects organic compounds like formaldehyde which has suspected links to nasal cancer and lung cancer emitted from many household materials. By measuring particulate pollution, an air pollution monitor can also help you know when asthma may worsen and when to change your home’s air filter.
  • ORIGINAL DESIGN & USA BASED SUPPORT – We have Midwest-based technical staff including a chemist to answer any questions you have. Also included will be a 20+ page eBook on Gas and Air Quality Hazards. We have worked with the supplier that holds this air quality detector’s design rights so you can be confident this item is tried and tested.
Works as described on Amazon

We bought this product because of the air quality problems in Western Washington during August of 2017 and 2018. Global climate change has changed our environment forever. Forest wild fires are all around us. During August these fires have made the air quality in Seattle one of the worst in the world. We bought an Air Scrubber for our furnace to clean our indoor air from particulate matter. It seemed to work but did it really? So I bought an air quality monitor from EG Air through Amazon. The device works as described on Amazon. This is just what I wanted it to do. So, this is high praise from me. I compared air quality readings from inside and outside the house and yes our indoor air quality was better. As an added bonus I measured the VOCs (Volatile Organic Compounds) in our bedroom with EG Air's air quality monitor. This is usually out-gassing from different products into the air. We found that just opening our bedroom window reduced the VOCs when it is not smokey outside. Thank you EG Air for your product.

Amazing Device No Home Should be Without!

My 6 yo daughter keeps waking up around the same early morning time with a very bad cough. Discussion between my wife and I thought it to be an eviromemtal issue since it kicked up soon after we started using our central outside natural gas heat. She already sleeps with a humidifier to help keep moisture in the air. We thought possibly a gas or exhaust coming through the vent. I searched online for a reasonable user friendly Air Quality Monitor and found this one. I'm no expert but it seemed easy enough to operate and set up. Although the enclosed user manual is a wee bit short on details, enough is there to get you up and running. Fully charged, calibrated and ready to see what could be causing my daughter to nightly wake up at 3 a.m. coughing. After allowing it to run all night I immediately checked it the following morning. It showed absolutely nothing but green and clean fresh air. No contaminates other than some point 003 dust. I knew I must have done something wrong so I called HVAC/Air Quality professional in. He came and checked the house out top and bottom. He found nothing also. I showed him my Air Quality Monitor I had used and he was glad to inform me that I had a good one to use and he said after looking at the logs that it was spot on with his findings. We are still searching for the cause of the cough but we know thanks to my purchase of this Air Quality Monitor from EG EVERHOLD LLC that our air is clean and that I have a nice tool to use to help keep it that way! No issues, No complaints and if I did have any I'm sure customer service would help immediately. A plus is that you can check the air quality anywhere also. Use with the enclose ac charger or with the self contained battery, either way I'm glad I bought one!

Actually Works

I have to confess that I had a dubious outlook when I was contemplating the purchase of this product. But what a surprise, the product actually works. Quickly: I had allergy problems stemming from the air in our apartment. By using this product I was able to determine that I was reacting to the VOC's emanating from the two new chairs that we had recently purchased. Chairs went back, eyes cleared up. I wouldn't have had a clue what the source of my problem was without this product.

Helped me track down multiple sources of air pollution in my home.

I was having trouble with severe eye irritation. It would go away if I slept with the window by my bed open. I left the windows open in the house overnight to clear out the pollution. By the end of the day the gunk in my eyes would make it impossible to read or use the computer. I used the air quality monitor to "sniff" out the sources (there were several) of the TVOC and formaldehyde and got them out of my house. Plastic containers (not food grade) and garden chemicals...laundry detergent in a plastic bottle. All were stored in the laundry room, which made it easier to find them. Life is much nicer now!

Peace of mind with this nifty gizmo

I don't get why some people say they had a hard time figuring out how to use this! It comes with quick instructions plus I got an email link directly to the full user manual. Piece of cake! I love taking it around my house to see how I'm doing with the aspergillus mold in the damp cellar room as I repair a leak there, and in the attic where I feared there's VOCs from spray-foam insulation, and just for kicks, in the kitchen when the VOCs are through the roof when we're cooking. But seriously, for a layperson with allergies and anxiety about dust and mold and other scary crap in my air, this is the perfect DIY thing to measure and reassure or inspire action!

WORTH IT'S WEIGHT IN GOLD

I purchased this due to the fact of air quality in my town due to refinary's and also the multitudes of fires burning in California at any given time lately. What I was surprised to find that my own house was polluted due to the fact that due to the fires we were keeping our house shut down tight. Due to all the products that gas off (I'm just learning this) in any persons home, it is best to have a fresh air supply available via open windows "daily" with fresh air or a good quality air purifier to clean a shut up house when avoiding pollutants outside. This meter has been a true life saver to me. The best part is that you can pretty quickly discover how good or bad air quality is anywhere you go. The one improvement would be longer battery times, but it does have a USB charging plug and can be run while plugged in. I'm not easy to please, this monitor has really helped.

accurate and useful

we used this monitor in many places. Do you know that the HCOC are super high in your car? Use this then you will know

Regardless of it's shortcomings, I give it 5 stars!

Upon my initial observation of the box that this device was shipped in, I was kind of amazed at the quality of the packing and the device itself. I've been using this device for the past couple of days and am fairly impressed with the accuracy and sensitivity of the device. An absolute must for anyone with allergies, or if the household is getting sick for no apparent reason. I highly recommend you follow the directions, especially during the initial unpacking of the device. As recommended, you should leave the device outside in open air for at least 30-60 minutes before turning it on to allow all sensors to vent. Some sensors contain heating elements within it thats necessary for it to function. For best results, let everything air out before applying power. Once I got the device working, I was utilizing it to measure various areas. I took it to work to measure the air quality in one of the datacenter labs and had HCHO of 0.000, TVOC of 0.001, and PM2.5 of 000. The device pretty much provides real time stats because as I was working in the lab, every time I walked by the device, the readings changed very slightly (i.e. TVOC 0.001 increased to 0.005, PM2.5 went from 000 to 002, etc). Numbers all went back to zero after a few moments. This device is so sensitive, as I walked around my home, the measurements showed up in real time. When I walked into the hallway, readings dropped fairly low. Reason is we have a HEPA air filter in the hallway situated near the cat litter. This device is so sensitive, it can tell a difference when I drive down I-280 and I-101 with my windows down. Where I live, I-280 is a freeway completely surrounded by trees, whereas I-101 is mostly industrial. Readings are much lower when driving along I-280. See? Trees are very beneficial to help keeping our air clean! This device is so sensitive, it kinda makes going #2 fun. Because fecal matter releases VOCs due to the sulfurs, and many other chemicals used in your body for digestion, it will register a higher TVOC value on the device. Stinker the poop, higher the TVOC value! You or someone smokes? While smoking, run this device and see how detrimental smoking does to your air quality. Second hand smoke is no joke! Live in California like me? Take this device (rechargeable battery and portable, so convenient!) with you when you go outside to check your air quality due to the many wildfires going on in the state. Although this device will tell you your Air Quality Index (or AQI), it won't be able to do anything more than tell you. Very helpful to allow you to take extra measures to protect yourself (especially if you have asthma, such as myself). Because this device measures the separate AQI values in real time, use this device to check the effectiveness of your air purifier! Bought a new car? Take a reading with this device in your new car's interior. That new car smell, believe it or not, is the emissions of formaldehyde caused by glues and resins curing. Bought new furniture? Use this device to check the HCHO levels that new furniture has the potential of giving off. Most furniture is made of MDF, or particle board. Particle boards are bits of wood bonded by chemicals and glues that emit formaldehyde. What I thought could have made this product cooler: * Ability to save histograms when measurements is started. You have to be on the graphs page and leave it there to get historical graphs. If you leave the page and go back to it, you won't be able to view past measurements. * Ability for the device to save calibration data across power cycles. When you calibrate the device and zero it out, next time you power cycle the device the readings may be a bit different. * Ability to export results over time * Ability to change the user interface color schema This product is perfect for taking spot measurements to get a good idea of present environmental conditions. You won't be able to see past readings. I highly recommend getting this product!
