EDIT: Misread the title :smacks head:
I have a couple of the Coway 250S (also wifi connected) and like using the scheduling feature. The best way to use these is to set it to a fixed speed, and forget it. The "smart" fan setting will react to changes, but after a certain amount of time, it'll turn off and go into energy saving mode (turning on periodically after that.) In this mode, if they dont sense air changes, they may barely run at all. Since they sit in a portion of a room, the quality of the air around the sensor may not represent the room. I wish there were a way to set a minimum speed for the smart setting versus the purifier turning off completely.
With the S-model schedulers, I force all of the purifiers on mid-day for a couple hours (at max setting), and at night (10PM - 9AM); they sit in the "smart" setting (ie barely running) for the other periods of the day. Since its also wifi connected, you can also go back and see the history of the air quality. If you are into data, its cool to see how the air quality can deteriorate when doing certain things (cooking, 3d printing, etc etc); you can set up push notifications for this as well. The 250S has more detailed metrics than the 300S, so I wonder if the 400S is the same (the 300/400 may be a generation older than the 250S - not sure.)
All that being said, at $340, buying two of the smaller air purifiers (like the Coway Mighty or Winix) will perform better (and be cheaper) than this.
While not smart it does remember the settings and on/off so you can put it on a smart plug and time it that way. This is nice because many digital control devices (eg fans) don't turn back on, but this does.
The thing you miss with a plug vs the smart version is you can't set specific power settings on a schedule. Just on or off. But I have had it on the lowest setting (non smart/sleep) and schedule it to run through the day and it has met my needs.
Being able to set it to the highest when I need it (cooking, etc) and setting it back down has been convenient enough.

Should I return this new purchase, and buy a smaller one? Beside helping w/viruses, my area is dry and dusty plus I'm on a major hwy. any thought are appreciated!

ConsumerAnalysis has a good explanation on this:

Why and how? It has to do with the fact that one AirMega at approx. 430 CFM is still only one air purifier representing a single location in the room where dirty air can be taken into the air purifier and clean air is outputted back into the room. Our testing showed that multiple lower CFM (250 CFM) units spread out around a large room are much more effective than a single high CFM air purifier like the AirMega.
Ignoring that, I think the smaller units have more placement options. The 300/400 require both sides to be open while the smaller units only need the front to be open.

I keep checking it and moving things around the room to see the light change, it stays blue more than anything. Now I have it on just the high speed setting. It's in a back bedroom and there's a treadmill, and odd/ends junk.
My living room 400 is always turning purple when people walk by or such. (I most definitely took the plastic of the filters too! haha ) Any thoughts? There are only two of us here. No pets. Any thoughts? Thank you!
