## Description

Have you gone nose blind to household odors?Check multiple measures of your home's air quality. This air quality monitor has a fan onboard that allows REAL-TIME accurate monitoring of formaldehyde (HCHO), total volatile organic compounds (VOCs), and <2.5 micron-sized fine particulate dust (PM2.5). Formaldehyde is an environmental carcinogen yet odorless at lower concentrations that can off-gas from various building materials. Detect low levels of airborne organic compound and odors or VOCs emitted from biologic and synthetic sources such as plastics not perceivable to the human nose. Check microscopic inhalable dust levels with PM2.5 levels.Problems with allergies?See when you may need to change your home’s air filter. Watch the levels of formaldehyde and VOCs drop when the windows are opened. Learn where air quality is poorer and where your allergies can worsen. Allergies that are difficult to control with unexplained coughing, runny nose, and shortness of breath may indicate sick building syndrome. Tips on Use:-PM2.5 reads in μg/m³, not AQI; search AirNow AQI calculator online for conversion.-Large variations or 9.999 TVOC readings do not indicate an error as this instrument is a sensitive electronic nose; environmental TVOCs vary much and high TVOCs often can result from interference from benign fragrances or odors.-Calibrate if 0.000 indoor readings noted or with new device.Specifications:-2.8” 240 x 320 LCD-2200 mAh Li battery; DC 5V micro USB charging-HCHO Range: 0 - 1.999 mg/m3-TVOC Range: 0 - 9.999 mg/m3-PM2.5 range: 0 - 999 μg/m3; PM10 calculated from measured PM2.5-Adjustable alarm for various HCHO levels and auto-shutoff timing (up to 2 days).As the only US based retailer of this item, we have a chemist on staff to answer any technical questions. We also email our 20+ pgs eBook on Gas & Air Quality Hazards after delivery.

Review: 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!
Review: There was nothing I disliked about this.... Once calibrated, it showed me that I had a big problem with my air quality due to VOCs from an item I had purchased .. I removed the item..I removed the problem...not confused, headache gone, coordination back to normal, asthma clear...if in any doubt as to what you're breathing is safe...GET ONE...I was a novice in these matters...this cleared my mind and also my breathing.. EXCELLENT

## Features

- MULTIFUNCTIONAL & SCIENTIFIC – This indoor air quality monitor accurately assesses multiple measures of air quality including concentrations of formaldehyde (HCHO), total natural & synthetic volatile organic compounds causing most odors (TVOC), and fine particulate dust matter measuring <2.5 microns in size (PM2.5) which travel deeply into the respiratory tract, reaching the lung alveoli and can worsen asthma.
- PORTABLE TESTING – Spot check indoor air quality anywhere or leave device on for continuous monitoring up to 2 days. This easy-to-carry air quality tester can help monitor air quality at home, in the car, and in hotel rooms. The 2200mAh battery provides portable power when DC 5V micro USB charging is not available. Information is displayed on a clear 2.8” 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.
- 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.

## Questions & Answers

**Q: Does this detector work for checking for mold?**
A: It can check for TVOCs (organic compounds dissolved in air) and PM2.5 (micron dust levels) which can indicate presence of mold but it does not specifically check for concentration of mold spores.  Thanks for asking.

**Q: In testing for formaldehyde & you have a certain product do you place a plastic bag around the product and insert the tester inside?**
A: That is a very good question:
1.  What I would do is place the tester in the bag without any product to get a baseline and then place the item to be tested in the bag for about 1 day to achieve equilibrium.  
2.  Then you can put the tester in the bag for at least 30 minutes or until readings stabilize.  
3.  Subtract the tested item reading from the baseline reading to get the formaldehyde emission amount from the tested item.  

Hope this answers your questions, take care!

**Q: Does anyone know how to get the ebook?**
A: I just received my new detector and no ebook or directions on how to get it. It doesn’t look like Amazon is very responsive.

**Q: Can this monitor be used for outdoor air quality monitor?**
A: The monitor can check for outdoor particulate matter (PM2.5) levels; TVOC and HCHO levels are generally negligible outdoors as they are from synthetic sources.

*by G***Y on 2 September 2022*

I have never bought or used a product like this before, so this review is only relevant to this being my first air quality monitor. Having said that I have no reason to 'disbelieve' the data it's presenting to me. I bought this after being hospitalised due to a rare bacterial infection which, possibly coincidentally, occurred after I had removed some tiles in my bathroom after spotting a leaking toilet seal. For peace of mind, once I had returned home, I thought I'd buy an air quality tester to see the state of the air quality in my flat. I'd already covered the open tile area with pvc sheeting. The air quality in various rooms, including the bathroom area, was of good quality. I placed this monitor inside the pvc sheeting (and re-sealed it) to see what it said about the air there (that had been open prior to my hospitalisation). It came up as 'unsatisfactory' - which may have been the cause of my illness. I would say this gives you peace of mind if you suspect the air in a room is not of acceptable quality, or gives you the evidence to take corrective steps. After replacing the tiles and re-grouting the bathroom that had the missing section, the air quality is reading 'good' again. I would recommend this to give an indication if something may need further investigation.
