I live in China and have a Laser Egg (1) in my home. It's extremely accurate, often matching the AQI reading found by online services. What I'm interested in is learning how to purify the air inside. I knew cooking was a major culprit in raising PM2.5 levels. But even when running two air purifiers sometimes the AQI just can't be lowered too much. I think it's leaky seals in the apartment. We're on the 18th floor and on a windy day can feel a huge draft from the front door and hear the wind escaping the balcony windows.

- martian 10y agoI bought a top rated air purifier a couple months ago off of the recommendation from Wirecutter. I live in SF, not China, but it's dramatically improved quality of life in my apartment. It cleans out smokey air from cooking very quickly, and cuts down dust/particulates especially in the spring months when pollen is everywhere. Highly recommend.
- cglace 10y agoJust curious, which purifier?
- chdir 10y agoProbably Coway AP-1512HH Mighty. http://thewirecutter.com/?s=air+purifier http://thewirecutter.com/?s=air+purifier redirects to http://thesweethome.com/reviews/best-air-purifier/ http://thesweethome.com/reviews/best-air-purifier/
- martian 10y agoYes, the Coway. I've had it for a few months now and just leave it on all the time on auto/eco mode.
- Sukotto 10y agoIf you haven't seen it, this TED talk on using plants for air purification is pretty cool: https://www.ted.com/talks/kamal_meattle_on_how_to_grow_your_own_fresh_air https://www.ted.com/talks/kamal_meattle_on_how_to_grow_your_...
- derefr 10y agoOne thing I've never figured out about air purification is how to keep air both particle-free, and oxygenated. I don't want to seal all my doors and windows to run an air purifier—I immediately feel suffocated by the CO2 buildup from my own breathing. Is there a best of both worlds?
- TheRealPomax 10y agoMore plants in your house. It makes a surprising difference.
- eightysix_four 10y agoFresh air systems are what you are looking for. They purify and bring in outside air (be warned, they lower HVAC efficiency), a lot of them with a high enough CFM to pressurize your house to, exhausting all of the air inside outward so that the leaky seals aren't an issue.
- seanmcdirmid 10y agoThe problem is that these don't fit into most Chinese apartment rentals. Landlords could make some big bank by installing an HVAC, but they are missing even in new buildings where 90sqm apartments are going for more than a million bucks.
- derefr 10y agoYep. My little apartment (400m²) in a low-rise in Canada, built just five years ago, has no in-unit ventilation whatsoever. If I want a cross-breeze (and I always want a cross-breeze), I have to open the outside windows and the door to the hallway, and let a ton of dust and pollen flow into the unit from outside. I have no idea who thought building an apartment building today like this made sense, but it seems to be a common perspective.
- seanmcdirmid 10y ago400 sqm is a "little" apartment? Sheesh, first-world problems :)
- seanmcdirmid 10y agoYou need good Windows. We switched our apartments in Beijing, and it made a world of difference in indoor air quality with our big blue air running. The problem that "purified air" becomes stagnant enough to be uncomfortable, even if clean, so we open the windows whenever the AQI is below 170 as long as a dust storm isn't going on.
- lisivka 10y agoI have purifier with large HEPA filter, purifier with water filter, ultrasound humidifier, but the best result so far is by vacuum cleaner with water filter (Thomas with Auquafilter). Water works extremely well against tiny particles, much better than HEPA.
