The large surface area and thickness of the filter are excellent. The unique easy in/out cleanable pre-filter makes it so easy to clean it (with a vacuum cleaner). The best for keeping clean.
I also like the colored air-quality indicator light, which can be seen and understood from anywhere in the room, but it is too bright, and turning it off is not what I want, so I had to put a white sticker over the colored light to reduce its brightness. Problem easily solved. Amazon sells the LED brightness-reducing stickers.
As with other air purifiers, the Auto mode is unusable due to going asleep automatically. I leave it set on 1, which is fine; no real complaint about that. The only thing I like about Auto mode is that it provides an auditory indication when the air has become polluted, so it would be nice if the purifier makers could figure out how to make Auto modes really work right, like not going to sleep automatically, and allowing the user to set the minimum Auto speed, and prevent the Auto from turning off the air-quality light.
They should provide a sticker to reduce the LED brightness along with the unit, so users don't have to find one themselves. Or maybe even a variable brightness setting.
Even with the small negatives, this is the best air purifier I have found for the price. I bought a second one after liking the first one. However, I also bought and use multiple Winix 5500-2 and Winix 5300-2 purifiers, because they have better air-quality sensors, and even though the Winix filters are not as large, and the Winix pre-filters are not as easy to clean, it's good to have both, because the Winix units let you know when the air is polluted way more often than the Coway does.
If you can afford it, it's better to have many air purifiers operating at low speed, than to try and rely on one for a large area operating at higher speed. The lower the speed, the better the filtration, the less often the filters need cleaning, and the lower the fan noise.
