Temtop Air Quality Monitor PM2.5 PM10 Particle Counter, Formaldehyde, Temperature, Humidity, TVOC AQI Tester for Indoor/Outdoor Air Pollution Detection w/Data Export

The monitor was recommended to me by an environmental health professor at the University of Tennessee. It works great, and the instructions are very easy to understand. I have mass cell activation and need to have consistent and reliable readings for my environment. The battery life is very good as it lasts quite a while before needing to be charged. There are no batteries which I like, and charging is easy. The readings are clear and I would suggest reading over the instructions as humidity can cause fluctuations that are inconsistent with correct numbers. I would definitely recommend this product for anyone who has chemical sensitivities or does not want to breathe air that is toxic. We have had some remodeling and it has been a lifesaver, knowing which environments were safe. I highly recommended it!

Sometimes ya get what ya pay for. Not disappointed by performance of this quality device. Readings agree with my Davis AQI monitors. Quick to update results on the display. Especially in the home, a reliable handheld device that displays Accurate AQI, TVOC, HCHO Readings let you know "How Much" so you can address unhealthy levels of contaminants in your personal space. A little work to monitor can help you improve your indoor air quality. Have a high AQI reading in your home from high pollen or neighbor's smoker going all night? Turn on a box fan fitted with a MERV 13 air filter and monitor the result. Have an unhealthy TVOC HCHO reading in the home and much lower reading outside?? Position a fan to exhaust (suck) inside air one one side of the house and open a couple of windows on the opposite side (and monitor the TVOC HCHO readings. Yes, the AQI may go up while the "fresh" air is flowing from outside but the MERV filters will take AQI readings lower when the TVOC HCHO exhaust process is complete.

This does not give accurate readings. Have used it near areas with high toxic chemical smells, mold smell etc. and it does not register how bad the air is. It was reliable outdoors as well. Sometimes the temperature is not accurate either.

Purchased this to monitor the air quality in my home. It comes with great instructions and is very easy to use. It displays consistent readings so I've found this monitor to be very reliable and sensitive to factors that could impact the readings. The battery life is sufficient especially is using it for several hours but could be a bit longer. It comes with a charging cord, readings are easy for us non-air quality professionals. It's great value for the money and works very well. We use it several times a week both inside and outside. Easy to travel with as well to take along on trips to monitor air quality various places.

Super was to use and very accurate.

When you live in a neighborhood with, mixed income let's say, eventually you find yourself having to deal with seedy people When the neighbor "cooks" it's never the particulate matter that's the issue, it's some type of "VOC" that is produced, that, over time, will not be conducive to overall health BTW, law enforcement should buy these by the pallet

I'm very happy with the particle and VOC measurements that I'm getting from this thing. The numbers seem reasonable and they update with only modest delay relative to the triggering event (e.g., lighting a match). It even tipped me off to unhealthy particle concentrations in the air coming from outdoors---which I found out after the fact was being reported in the news, I think because of wildfires from Canada blowing south toward NY. And it showed that my car has unhealthy VOC levels when I first start it and that it takes a good 5 minutes of airflow for them to drop down to healthy levels. I had no idea. But the main thing I got this for is still coming up: tracking the particle and VOC concentrations while soldering to check if my relatively cheap fume extractor is working as advertized (looking at you, Weller) or whether I need to cough up the big ponies for a more proper model. I do have some complaints: the plastic feels super cheap for this price point and it smudges easily, the screen display is super basic, and the supporting flap in the back that allows you to set this vertically on the table opens far too little to provide decent support---the end result being that this thing is constantly tipping over. Who on earth approved that flap design? It makes zero sense and it's almost useless. Overall this thing feels like it was designed way back in the 90s with just the bare minimum updates done to keep selling it year after year. Not saying that is the case, just saying how I perceive it. I think the bright orange and black looks awesome and they should keep it, but the plastic needs to be higher quality, the supporting flap needs to be redesigned to pull back more for support, and the digital display needs to be refreshed to convince us consumers that it was designed in this decade. The battery life is not super impressive for a device this small and basic though it seems to last 6+ hours between recharges. I'm not familiar with the sensor electronics so I don't know if they are just expected to consume that much battery, but, you know, modern portable devices get far better battery life than this on far more demanding tasks than this. I love that the device does what I need it to do very well---to track particle and VOC levels over time in a package that I can trust. But I think at this price point they need to do better on the packaging, display, and battery life. So I'm giving you three stars, TemTop.

The AQI meter seems pretty accurate in measuring air pollution. I put it outside when I want to measure the air pollution and in a couple of minutes I get a good measurement. It's pretty close to what I get from my local airnow readings. The airnow readings are much more precise and accurate because they use a very expensive machine but the airnow readings are an average of the last hour or so and my meter measures the moment I am looking at it. Plus the airnow machine is 6 miles away and may not be accurate to my local area as it is in the area it is measuring. It is supposed to be 91 percent accurate as opposed to the purpleair meter which is a little higher in accuaracy. All the purpleair readings I see on their website comes up much higher than airnow and my meter because there are two settings on the purple air and the default setting is much higher. As a result, it is hard to compare the TemTop meter with the purpleair meter. Overall, I like the TemTop meter as it measures air quality well.

good

Livré dans une belle boîte en carton, bien emballé, parfait état. L'instrument m'est parvenu déjà calibré, mais j'ai effectué 1h de mesure en extérieur au cas où. En intérieur, l'appareil semble fonctionner, les mesures en PM2.5 et 10 semblent cohérentes. Un exemple, dans une pièce propre et bien ventilée: PM2.5 = 6.1 (ug/m cube) PM10 =10.5 (ug/m cube) Nombre de particules: 1063 Et si je fume une cigarette dans la pièce les valeurs dépassent les 300. PM2.5 = 307.3 (ug/m cube) PM10 = 553.8 (ug/m cube) Nombre de particules: 46 176 Cela me semble d'autant plus cohérent qu'un autre appareil: le QingPing air Monitor affichait 315 pour les PM2.5 dans la pièce où j'avais fumé. Par contre! J'avais acheté cet appareil dans l'espoir d'obtenir une mesure élevée des particules dans l'air à cause d'une odeur en particulier qui me pourrie la vie au travail, de temps en temps, c'est irrégulier. L'appareil ne semble pas détecter cette odeur, y compris sur les mesures en COV. Reste un très bon objet. Dommage il ne mesure pas le CO2 (comme le QingPing), il faut prendre un modèle supérieur. ATTENTION cependant: l'écran se micro-raye facilement.

Buen servicio,aparato perfecto.

Hervorragendes Produkt. Ich kann nicht beurteilen, ob die Werte für wissenschaftliche Arbeiten herhalten könnten aber für meinen privaten Gebrauch ideal. Das Gerät merkt sofort Veränderungen z.B. durch meinen Kamin oder Räucherkerzen oder kochen. Es hat mir gut geholfen, meine Raumluft zu verstehen. Einziger Nachteil, dass man es nicht im Stehen laden kann, da der Anschluss unten an Gerät ist. Aber ein Punkt Abzug dafür, wäre dem guten Produkt nicht gerecht.

Brilliant piece of kit. Every home should have one. Highlights where the pullants are- kitchen surfaces, extractor fan not working, dust build up. Also brilliantly it reacts quickly - like opening windows. If you have allergies get one of these. As it’s portable it’s great because you can walk around with it to check areas.
