Air Quality Monitor Professional PM2.5 PM10 Particle Counter Formaldehyde Temperature and Humidity TVOC AQI Tester Indoor Outdoor Air Pollution Detector w/Data Export

Yes this a very good device well made and accurate. But it requires some expertise to get usable data. I don’t have the skills. But yeah if you know what you’re doing it’s high quality not for amateurs

Moved into a house with a log burning stove and was concerned about air quality. This gives a really good idea of what particles are in the room. Usually fine but lets you know if something is wrong.

Did what it says it does. Very useful

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.

Ready to go in the bin after 3 months. One before this was the same. Even another temtop model that just measures PM 2.5 and 10 broke down and stood charging after 2 months. So three temtops at over £300 in total which didn't even last 10 months. I would avoid this make. I concede it is very difficult to find a reliable quality air monitor but it may be worth looking for a commercial grade one in my opinion. These are exorbitant given they barely last 3 months

It is very good and very accurate. Amazing product and covers all as mentioned.Would definetly recommend this model.

great value for money seems very accurate and easy to use.

Poor quality stoped working after few days

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: 1063Et 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 176Cela 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.

My measurement is correct; I confirmed it. It’s a pretty good product.

This is a great gadget that reminds you when to ventilate, especially if you recently installed Ikea furniture, PVC or laminate flooring, or a new sofa that might release formaldehydes. It also detects dust particles if your AC isn't using a filter. On the plus side, it's a good, reliable measuring tool. Easy to use, charge USBC runs long enough or just add powerbank or direct to charger if you need 24\7 control. Little pricey hope it will last long. There is internal "ventilator" moving air for measurements but you can bealy hear it. Compact hand light weight gadget.

Does what it says. Use it for my bedroom after installing new wood floor. Easy to operate

Accurate
