I've been in the country for less than six months. Previously where I lived, the air pollution was sometimes so bad that you couldn't make out skyscrapers a kilometer away. Friends would come down with asthma attacks after a day out, and they were not asthmatic.
So I move to Sydney and the air is, in comparison, just insanely clean. The only thing that gets me here is all the bloody pollen from the damn nature that I'm surrounded by.
But every time I check this forum, there's a post or a deal about air purifiers- why?
Far as I can tell, unless someone is living next to some illegal and unregulated coal burning power plant that's managed to fly under the radar (/s) or there are active bushfires nearby, the air here is crazy clean. I'm not just making this up, out of habit I ran particle counters for years, then after a couple months here realised there was no longer any point even turning them on. And if you've got a problem with pollen like I do, air purifiers do sweet FA unless you otherwise hermetically seal your house and don't go outside.
So why are people buying these $500 or more devices (which in themselves consist of nothing more than a fan and a cheap HEPA filter)? Is it something that came out of the bushfire seasons years past, or has there been some other source that's caused so many people to worry about air quality?
Don't get me wrong, I am not against them per se. I currently own four (use none) and have over the years rotated through at least a dozen, some DIY. But Australia is one of the cleanest countries on the planet, and this forum has constant mentions of purifiers.
The air here is clean to you and I. Have you considered others may differ?
Lots of people struggle with pollen or dust or odors or pet dander or other allergies etc.
