I've never experienced an air purifier, what's the general consensus?

Do they make a difference? Perhaps a placebo? A must have?

Genuinely interested if I'm missing out - For what it's worth I do live right on a main road in the UK, so I expect there is some level of pollution in the air.

I (in London) bought one recently (a COWAY Airmega) to try and improve the air quality in my apartment, specifically, the dust which has been reeking havoc on my breathing because of allergies.

There is a noticeable improvement but it has not solved the problem by any stretch: so while I don’t regret the purchase, and will keep using it, I am not how sure I’d recommend them for the someone without breathing difficulties / allergies etc.

PM2.5 particles are considered harmful, ingest at your own peril. Some air filters will also include an air monitoring device, so you can just for yourself how many of those particles are present (partially burnt food is an extremely common source of these).

I was so skeptical. Living in SF in 2018(?) during the wildfires, my apartment was drafty and I’d come home from work to a hazy indoor environment. I’d wake up with a sore throat and that’s what got me to take action (can’t sleep with an n95 on)

I got the cheapest air purifier from Amazon and just put it on my bedside table. After one night my sore throat was gone.

As simple as these machines are, they do work.

My parents live in a very old house (~1700s) and it reduced the dust significantly. Not perfect but maybe it's on the model too. Like it's not an $1000 one which would probably work much better

It really depends on where you're coming from.

I have one of those air purifiers from Ikea (Förnuftig). It's cheap but not the cheapest. On any high dust/polen concentration level day, a minute or so with the device turned on at full blast is enough to make any problem go away in that particular room.

We live in the city and always are struggling with allergies. The whole family is always coughing or sneezing. We bought a xiaomi air purifier like in the article last week, started using it in the bedrooms for a few hours in the evening, and the allergies cleared up overnight. The particulate sensor is mostly useless, a known problem with the xiaomi models, but running it at a fixed setting seems to clean the air quite effectively.
