Coway Air Purifier
When you unbox the Airmega 300, you immediately sense the time and care that went into the design. It feels like unboxing an Apple product. The materials were lovingly chosen and it all slots together in a satisfying way.
When you switch it on, it automatically detects how much filtering is required for your air. It'll run on high until your air is clean, and then back off to a quieter mode. I put it right by our front door. When Seattle was slammed with wildfire smoke, each time I opened the door the Airmega would kick into high gear for a minute before settling down again. It really makes you feel like your air is clean. Immensely satisfying.
Internally, it has a couple of high quality HEPA filters to strain out the dirty wildfire smoke. If you can afford it, definitely pick one of these up for wildfire season. Don't wait until fire season, because you won't be able to find one!
We also bought a couple of smaller Coways for other parts of the house. The build quality is just as good and they seem to run the same software, but they are built for fewer square feet.
