Product description
Have you gone nose blind to household odors or dust?
Take control of the air you breathe—because your health starts at home. This air quality monitor provides real-time insights into invisible threats in your environment. With a built-in fan for active air sampling, it delivers fast, accurate readings of key factors: temperature, humidity, formaldehyde (HCHO), total volatile organic compounds (TVOCs), and fine particulate matter (PM1.0/PM2.5/PM10). Whether you’re improving comfort, protecting family, or avoiding long-term exposure to harmful pollutants, this device puts powerful data at your fingertips.
Many indoor pollutants are silent and invisible—yet they can seriously affect your well-being. Formaldehyde, a known carcinogen, often off-gasses from flooring, furniture, and paint—odorless and undetectable without a sensor. VOCs from cleaners and plastics can linger, while fine particles can enter your lungs and trigger asthma, fatigue, or worse. This monitor reveals what your nose can’t—so you can act before it impacts your health.
See the Air You Breathe—Take Action with Confidence
Know exactly when it’s time to change your home’s air filter. Watch harmful indoor pollutants like total volatile organic compounds (TVOCs) and formaldehyde drop in real time the moment you open a window. Discover which rooms have poor air circulation or hidden pollution sources—so you can target the spaces where your health is most at risk.
If you or your family experience unexplained coughing, congestion, or shortness of breath, it could be more than allergies—it may be sick building syndrome, caused by prolonged exposure to poor indoor air. This smart air quality monitor helps you uncover the invisible triggers behind symptoms you can’t explain.
Whether you’re managing indoor air for children, seniors, or allergy sufferers, or simply creating a cleaner, healthier space, this compact, easy-to-use device gives you the clarity and confidence to breathe easier each day. Perfect for bedrooms, nurseries, offices, and any room that matters—because the air you can’t see matters most.

Tips on Use:
Calibrate on first use, esp. if 0.000 indoor readings noted. If the HCHO, temp, or PM2.5 is inaccurate, use the “Sensor Set” Menu found under SET (press D), then SENSOR (press A) to further calibrate device readings. Large variations & 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.As the only US based retailer of this item, we have a chemist on staff to answer any technical questions.
MULTIFUNCTIONAL & SCIENTIFIC – As our newest model, this indoor air quality monitor accurately assesses temperature in Celsius, 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 anywhere or leave device on for continuous monitoring. This easy-to-carry air quality tester 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 test air quality including 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.
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.

Mobbiest of all Mobby Dogs –
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 schemaThis 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!

Not accurate especially with worse air quality and follows China standards chart not US
** Update 12/8 ** I’ve updated from 2 stars to 4I had to post an update because of the amazing customer service.. it wasn’t immediate but it was efficient. I honestly didn’t expect much at all and was planning on returning my device. I did not and here’s why..I purchased during the CA wildfires so I could not calibrate the device and it was inaccurate. So, if you are buying during bad air quality outdoors it will not be accurate, though will still show you if things get better or worse until you can.Once I calibrated to the “fresh” outdoors a couple weeks later when our “hazardous” (worst in the world) air became “fresh” I could spend more time working on calibrations.. it took several attempts and did this over several days (2 weeks) in an effort for consistency. I did have to adjust manually but the online eBook was helpful through the process.I’m not sure I totally believe all of the HCHO are totally accurate as I know some essential oils that actually aid in respiratory health and if nearby will set the monitor off, then dissipate over 10-30 min and the machine is happy again. So, some things heavier than air will register.. know what is nearby and make your own conclusion as to your safety of the air.The PM2.5 which is huge for CA wildfires and to me, with a respiratory medical disability is most important. It is quite accurate though once you finally calibrate. Because of the time it took me to calibrate and believe the unit, I didn’t want to return the unit. What I found out was that it’s difficult to find machines that will show US guidelines so you will get a green, yellow, or red face on your machine. Just know, it is still green when it should be yellow/orange in US guidelines. I was willing to keep the unit for a discount for all of these difficulties and the company came through and compensated me more for my troubles.I’ve upped my rating from 2 to 4. My reason for not a full 5 is because of the time to actually get things working as they should and the fact I basically have the US standards memorized, I can’t always count on the happy green smile to be good for my own health. The readings however, are pretty much dead on now (outside) with EPA reports. I do believe your results will be accurate, however you may need to decipher them to US standards or your own personal sensitivities. The company is very receptive to questions and offering a response.—————————————————ORIGINAL POSTI purchased this during the CA wildfires when the air quality was in the “Purple/Hazardous” zone on the US charts (see my last photo for US PM2.5 values). Our air quality PM2.5 was over 300 ug/m3 but this tester showed a yellow “poor” face. Since you can’t calibrate it indoors, I had to wait 12 days to get a good air quality day. I’ve recalibrated the machine at least 5 times. The time apparently resets each time you do this too so the time is always back in 2015.I give the unit 2 stars because after calibrating is is moderately accurate. Not enough to use to measure actual air quality standards, but it will fluctuate when put near harmful products enough to know there are VOCs around. The fact it tests for formaldehyde is cool too, but I’m not sure about the accuracy as it jumps from green to poor and back for no apparent reason.Photos in order:The first photo is show what my unit looks like purchased at $109. I clicked in the link to review earlier today and this model ( https://www.amazon.com/dp/B074FTVHFN/ref=dp_prsubs_1) showed up with all the same reviews and comments as the model I have. Hmm As I review this afternoon, the image again shows my model purchased. Just be aware what you are purchasing.Second photo is after all of my calibrations on another day the PM2.5 was reported by the EPA here as 57 which is unhealthy. The unit read 54, not too bad. The PM10 was off considerably. The biggest issue I have is that after reading the manual, I finally realized why the unit kept saying “normal” when it was “unhealthy” by US standards. The unit goes off the China air quality chart (see photo 4 from manual). Photos 3 and 4 show air quality taken at the same time as the monitor indicated in photo 2. For this reason, the unit is not useful to me as someone with respiratory issues that needs the US air quality results. See last photo 6 for US standards chart and compare to what you will actually see with the unit on photo 5 China standards chart.It’s just too far off for me and I’m not going to figure it out on my own, though one could. I contacted the seller 3 days ago as their email said to do that before posting a negative review but have heard nothing back. My request was asking how to change the unit to US standards if it’s possible at all. If that can’t be done, I will be returning it. I’m hoping this review will prompt a response, otherwise the unit is going back.

Las lecturas de PM 2.5, PM 10, PM 1.0, temperatura y humedad no concuerdan con los valores verdaderos. En la calibración manual se puede ajustar la sensibilidad del sensor de PM 2.5 hasta mas menos 33%, pero en el equipo que recibí no fue suficiente. El otro ajuste disponible es básicamente sumar o restar un valor constante y se puede lograr que la lectura concuerde con el valor real, pero al poner una muestra de aire con PM=0 en vez de indicar cero muestra el valor que se sumó o restó. No hay ajuste de sensibilidad para la temperatura y humedad, sólo se puede sumar o restar un valor constante a las lecturas.No tengo medios para verificar si la lectura de concentración de substancias volátiles es exacta.Es posible que se trate de un defecto de fábrica, pero decidí pedir un reembolso en vez de un remplazo

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

I purchased a few different models from Amazon and had to send them back because they were so in accurate. This model has a fan which draws air across the sensors making the instrument respond faster to changes in the air. I’m a certified master inspector and use this as part of a preliminary air quality check. I would definitely recommend this product. As with any tool the user needs to understand how to use it and the principles behind what they are measuring.

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.

Firstly, concerning the accuracy, I am uncertain about how it is supposed to function. Each time I power on the machine, it requires calibration, and this process entails leaving the machine outside for a few minutes. If it were a one-time requirement, it would be acceptable, but the initial calibration process takes an unusually long time. The frustrating aspect is that this occurs every time you open the machine. Who has the time to consistently place the machine outside for calibration whenever they wish to check the air quality?Secondly, on their webpage, it is stated that returns are accepted within 30 days. However, when I requested a return on January 1st, it was rejected. After ongoing arguments, they responded on January 7th, claiming that it was already beyond the 30-day return period. Isn’t the issue that they consistently rejected my request, prolonging the process until it expired? From the seller’s perspective, this is absolutely unreasonable.Moreover, everything is in Chinese, posing a challenge for those who do not understand the language. Additionally, they essentially do not permit returns unless there is a product failure; dissatisfaction with the product is not considered a valid reason for return. Consider this a cautionary note about the product.
