OK so this device is fantabulous!! OK you MUST calibrate it correctly!! Follow the directions for the first callibration ever - I think that might be 20 minutes outside. Don't ever callibrate it inside. So each time, I set it outside in the clean air and let it do it's countdown in the fresh air. Now, I take it where I want to go and set it in the room for about five minutes. It has helped us SO MANY TIMES! We bought furniture from "The Cannery." It came with quite a smell. I am sensitive to some odors, what was the smell? Was it Mahogany or was it something else? This device told me that the odor was NO PROBLEM at all, so the smell was probably fresh mahogany!! Next, we were kitchen cabinet shopping. Didnt want to spend an arm and a leg. Went to to Kitchen Cabinet store in which the prices are AMAZING. They only sell like five colors of cabinets. The cabinets really looked amazing, even saw that the boxes were made of plywood. The cabinets were shipped in, and then the company would put them together - or you could yourself. We were very close to making an order but before hand, I just had to wonder... Why were they priced so well? I sat out in my car with my device callibrating up through my sunroof on the top of my car in the fresh air. It was time to go in the store... Hiding my device, I went into the store... Only moments later heading over to the cabinet section - "BEEP BEEP BEEP!!!" My device was sounding! Quick, I stuck it in the drawer of the cabinets - it was in the RED!! A little longer and I set it in another cabinet (it doesn't keep beeping) TALK ABOUT TVOC'S!! The formaldahyde was also elevated. OKAY SO YEAH. So just the AIR in that warehouse had elevated TVOC's and formaldahyde, I was concerned for the safety of the workers. They were mostly young and most likely naive to what they were breathing. I did a little research and after speaking with someone knowledgeable on the levels, I learned that the levels in the air shouldn't harm the workers, and that if I bought the cabinets, I'd probably need to air them out or run a fan on them - sound like for weeks or months to help bring those levels down. We've used this multiple times, and let a friend use it... It's fascinating, a great tool to help steer you in what you want to buy. DON'T BE ALARMED and freaked out - understand it's not PPM's - it's a different measurement. Be careful not to freak out and become a "Karen" when something reaches a high number, orange or red color and starts beeping. But, know it's helpful for you to help you make healthier buying deciscions.

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 just did some try outs today. Works perfectly fine, i got kind of concerned from people’s reviews saying the battery sucks or you can’t put out the alarm or change indication of where the alarm should go off. I literally changed those in 1 minute and it’s really easy to go into the menu. The battery life i don’t have any problem with since i use it in specific areas like at work or at home just out of curiousity for a 15 min and i put it off. There’s people complaining about a noise because of the fan. Mine makes zero noise, i’ve put my ear at the device to hear the fan ( because that’s a part of what it uses for measuring the air quality ) and until then i heard the fan. I think this is a good device, if i put it into a smokey area it obviously turns red, if in clean areas like forest it shows green, there’s people that wrote they started comparing with other devices showing different numbers, imho you will always get different numbers that way. I like this one it’s easy to take not too big. I think the only thing i don’t like is that it’s kinda light feeling and the plastic feels cheap, but overall good deal 👌🏼

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.

I bought both types to compare readings from this supplier and the reading for VOC is ready 4 x more on this one then the other! So something isnt right. Im going to buy another identical to the other one to compare the 2 against the original....will update. And PM10 & PM2.5 never differ from each other which seems odd.
