I've been looking for a good ozonating air purifier for a while. They've gotten a bit hard to find, so I was excited to find this one. It's not merely an ozone generator; it's intended as an air purifier that happens to generate ozone. That's good.
It is effective at its job. The ozone smells a bit funny to me; I'm not sure why. It's the real stuff and it's definitely there, but it smells a little different than what I'm used to. The fan moves lots of air, and it has an impressive stack of particulate filters. I like that all of the filters seem to be regarded as cleanable and reusable rather than disposable, and guidance on the proper way to clean each one is provided.
Not quite a five-star, because there are a couple of rough edges. The sleep mode is kind of pointless; it dims the screen ever so slightly, but it's still too bright by far to keep in my bedroom, and why have it as a timer? Just make it a toggle so I only push the button once to turn it on rather than several times to boost the timer high enough to go overnight. I don't keep packaging and manuals, so stop telling me to and instead give me a little pouch on the bottom that a card with all of the relevant information like button functions and filter cleaning procedures stows into.
This thing is nice, and it's definitely what I wanted. I'm happy with it, but for the price, a bit more polish is needed to make it a five star.
I would recommend this product.
