For air purifiers, if cost is no constraint, my IQAir GC has worked like a champ. The lower three speeds are reasonably quiet, and speed 6 cleans out the room in no time when my partner burns the cooking. Comes with a 10 year warranty.

Keep in mind air purifiers are just a fan with filters in front of it. A box fan with a furnace filter strapped to it, while ugly, will do similarly for reducing the amount of particles in the room.

What you're paying for is basically three things: a design that looks acceptable in a room, a fan that's reasonably quiet, and ability to source filters in the future.

Check, check and check. And also a filter quality and seal design that's been tested and proven to work (they do a QA particulate test on each individual unit before it ships https://imgur.com/a/exTrjU7).

IQAir are really good. My only complaint is that they are expensive and that their fan uses too much energy.

I wish they would release a smaller machine that was a bit cheaper and could compete in price and energy usage with mid-sized Coway models.

I have a few, just wish I could link them with an air quality sensor.
