Good air purifier - make sure you actually unwrap the filter lol
Style: Medium Room Air Purifier
I'm an idiot and didn't realize the filter that comes already inside it was in there wrapped in plastic for some reason that surpasses my understanding (the whole unit was already wrapped in plastic, why is the filter, which is inside the plastic-wrapped unit, also wrapped in its own separate plastic?? As if we need more plastic in the world...). Anyway, I didn't look inside cuz I thought the filter would just be installed in there and I plugged it in and cheerfully ran it for months til it told me it was time for replace the filter then bought a second filter and went tk take my old one out only to realize I hadn't been filtering anything all that time 😅 oops. Lol. So yeah, make sure you unwrap the filter. Otherwise it's a good little air purifier. Now that the filter is actually installed right, I notice it kicks up higher when we cook or do anything that would lower air quality, so it does seem to be detecting that properly! My allergies do seem better overall. It's pretty quiet when it's on low, but does get loud when it kicks up. I'm OK with that since it pretty much only happens when we cook or if I just put out a candle or something.

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.
