I got a laseregg 2, and highly recommend it or a similar monitor. It's been very eye opening to see how various scenarios affect air pollution:
* frying indoors generally swiftly puts things in the unsafe range. Especially if it led to browning.
* a neighbour's bbq would do the same if the window was open
* idling truck on the street for construction? Unsafe range
* surprisingly, the toaster would raise levels if it was on high enough to brown toast
Really helped me make better decisions about when to open/shut windows and how to cook.
I got the laseregg after reading reviews of air quality monitors used in china. Apparently it holds up well to specialized lab sensors. It has a battery and can be moved around
- nsporillo 8y agoSeems like the laseregg 2+ at best detects PM2.5, but something like the PurpleAir sensor can detect PM1.0 for roughly the same cost. Have you or anyone else used it? I'm interested in purchasing one.
- Forbo 8y agoAre there any of these types of devices that don't need to phone home or be connected to the Internet? The fewer "smart" devices I can have in my home the better.
- graeme 8y agoIirc the laseregg works fine with no connection. It can be connected, but isn't necessary. My co2 sensors have no connection either: https://www.amazon.com/Hydrofarm-Autopilot-Desktop-Monitor-Logger/dp/B01FYWU2IS/ref=mp_s_a_1_3?keywords=co2+monitor&qid=1557334844&s=gateway&sr=8-3 https://www.amazon.com/Hydrofarm-Autopilot-Desktop-Monitor-L...

- salex89 8y agoI've recently borrowed a similar device, and this one also measures formaldehyde. To be honest I'm quite anguished by it, because I can't find any indoors object with formaldehyde concentration less than 0.1ppm, which is the "safe" (by some legal standards) margin. Only outside or in a room with a wide open window it comes down under. It's even borderline higher in buildings not recently renovated. I've tried researching how dangerous is 0.3ppm or such, or how to keep it under control, but no luck. All sources are very academic...
- jspash 8y agoI'm now curious enough to want to get one of the meters. The reason being that everyone at work swears by the new wave of "mattress to your door" mattresses that you can buy online. Buy I insisted on getting a "real" mattress filled made of cotton, wood and springs. I'm still looked at like a caveman because I didn't go for the extruded oil hipster mattress and would like to be vindicated by evidence from an impartial electronic device. If only for the rights to say "i told you so". Equally if my so-called 100% natural mattress is giving of fumes, I'd like to know about it! Because I'm certain the living room furniture is doing so.
- jly 8y agoI was also curious, as an owner of a box mattress and laminate flooring. I used https://acsbadge.com/ https://acsbadge.com/ to do a highly-accurate one time test of my home and was happy with the results. Piece of mind to determine if you have a potential issue or not. They also give guidance on how to interpret the numbers and what 'safe' means (results are in ppm concentration accurate to 0.002 ppm).
- clairity 8y agoi bought a wave-plus[0] on a whim, and it's also been eye-opening. it doesn't measure particulate matter directly, but has a VOC meter (and radon, which is their strength) that similarly spikes for all sorts of things, including closing the windows at night. it's battery-operated and connects to a phone app via bluetooth (which then can sync to their cloud dashboard if you choose). i may buy a foobot[1] one day, as it was highly rated in recent studies on pm measurements, and has an api.

- graeme 8y agoRe foobot, did you see this? https://mobile.twitter.com/dhh/status/928661125327069184 https://mobile.twitter.com/dhh/status/928661125327069184 Airthings looks interesting. I'm curious to know of any reviews of their accuracy.
- clairity 8y agothanks! i had not seen that particular tweet, though i'd heard dhh was into this stuff generally. i'm a little less concerned about accurate co2 levels, since mitigation is straightforward (open a window). even imperfect co2 readings are good enough to signal when to open a window (around 800-1000 ppm, or ~2x ambient co2 levels). voc's and particulate matter are more my nemesis, as my lungs are more sensitive to that stuff. beyond knowing generally how bad the air is, i'd like to be able to figure out what is causing the bad air and how to mitigate it. information there seems lacking right now. i'd trust the radon sensor in the airthings more than the voc/co2 sensor, since radon is what they're known for. the voc/co2 sensor is probably the cheaper type used in most consumer air quality monitors, so it's good directionally but is not strictly accurate/precise.
- graeme 8y agoThanks! Got a link to that report you mentioned on the foobot, incidentally?
