Not worth it
Style: Medium Room Air Purifier
Disappointed in this air purifier. Doesn't seem to keep the air clean. Air filter needs to be replaced more often than other air purifiers. Unfortunately I can't return this product. Would not recommend this. Buy a Levoit air purifier instead. Works much better and filter doesn't need to be replaced as often.

Excellent Performance and Very Easy to Change Filter
Style: Medium Room Air Purifier
Very happy with this air purifier! It works really well and you can actually feel the air getting cleaner after running it for a while. It’s quiet, simple to use, and perfect for a medium-sized room. What I especially love is how easy it is to replace the filter. No complicated steps — just open, swap, and done in minutes. Super convenient and stress-free. For the price, the quality is surprisingly good. Definitely worth it, and I would buy again.

Works as intended, but is badly designed
Style: Medium Room Air Purifier
This air purifier is great so far. I've only had it set up for about a day, but it seems to me that the air is cleaner so far. I got it for my office, mostly to make sure that there's less dust in the air because my allergies have been going crazy recently. The downside of this product is that the manual is just completely wrong. Both the manual + the box say to turn the bottom lid counterclockwise to open. However, I tried that and literally could not open it for the life of me. When I looked closer, I saw that there were pins holding the lid in place, and that the only place they could move was to the right - which meant turning the lid clockwise, not counter-clockwise. That wasted 15 minutes of my time trying to figure out, because clockwise didn't work either until I wiggled it. Likely the plastic surrounding the air filter was caught in the lid. Like another reviewer mentioned, the bottom lid where the filter goes doesn't really stay on tight, which is annoying. It took me a few tries to be able to put it down without the lid coming loose and the filter falling out. It's light in weight but very loud, at least when it comes to being on high (full blast). Medium is tolerable, low is preferable for whenever I'm meeting with a client. Sometimes I even turn it all the way off. It was maybe worth the price? We'll see if it helps my allergies.

Very strong magnets on both sides.
Size: 12inch
You will want several. I use mine attached to the side of my large metal toolbox to make my frequently used tools easily accessible. But once connected to a large metal surface, it is very difficult to reposition which is a good thing. One surprise though, narrow shafted screws drivers don’t attach very strongly unlike other heavier tools with larger steel mounting areas for attachment. I am purchasing more for other areas in my workshop.
