Every time I use this, after a few hours I notice dust is all over everything in my home. Instead of blowing the purifies air up and around, they should reverse direction and it should be blowing from the bottom. Either that or it just doesn’t work very well
No, I would not recommend this to a friend.

Let's see how we can help! To get the most benefit from our air purifiers, it is recommended to place them in an enclosed room for a couple of hours. To more aggressively purify the air, try turning the unit to its highest setting. Please note that the unit is not able to pick up dust that has already landed on a surface. Do not hesitate to reach out if you have any further questions.
I’m really satisfied with my purchase and would highly recommend the Core 400S. I did a lot of research for an air purifier with deodorizer. I have allergies plus 2 cats. Within a few short hours of receiving and setting it up my runny nose stopped and the house smelled fresher. I purchased a Core 300S right afterward for my bedroom. Great product, easy to use and set up the app, and attractive as well.
Bought the 400S Smart True HEPA Air purifier to be able to control it from my phone. It is quiet. I like the feedback with the PM2.5 comparing indoors to outdoors. I also like the ability to program according to the day of the week or daily.
