I couldn't see it under CA carb-certified-air-cleaning-devices.
Does any one know if it is ionizing or just hepa filter?

Can you set a schedule for it to turn on and off at a specific time or does require the 400s?

I swear by this air purifier. I have 2 and the price for this is tempting me to buy a 3rd.

You will need the 400S model to schedule in the app. I have the 300 and 300S and I can connect with the app to schedul withe the 400S model. I agree with the poster that said never touched the app as I run both 24/7.

Not good to over purifier your air, lowers oxygen in the air! Placing them in strategic areas is key.
I feel like you probably don't understand a lot of life, science, the universe and reality.

This was the dumbest thing I've read in a while.

This is the dumbest thing I've heard today. Congrats. HEPA filters don't magically remove oxygen. They remove PM particles

It's wilder than that. Then he says place in strategic areas....like you can have different concentrations of oxygen within your household
