WYZEAir Purifier with Allergen Filter(Standard), for Home Large Room, HEPA 13, 21db Quiet Sleep Mode, 550 sq ft, Remove 99.97% Pet Hair, Pollen, Dust, Dander, Smoke, Smart WiFi Alexa Google, Black

My husband has poker nights and some of them smoke cigars. The last time I think 4 people were smoking at once and the smell never came inside my house even with people going on and out. Before we got this when him and one friend smoked the smell came inside and they barely went in and out of the house. Totally worth it!

I was very disappointed that this was sold to me as someone based outside the US when it clearly cannot function even with a voltage converter.

My experience with WYZE products has been hit or miss. Speaking of which, WYZE, if you guys ever stumble on this review, please, you really need to make a wireless outdoor camera that's solar panel powered. 'Nuff said.Now back to the air purifier. Simply put, this is a 5 star winner.BUILD: Solid. Sturdy. All black (except for the orange colored replacement cover at the bottom). Has front and back air inlet grills. Used round cylindrical HEPA filters with 3 level filtration.APPEARANCE: A rectangular tower. Nothing eye catching. Though I do wish it came in a white or grey color option. Control panel is at the top. Doesn't seem to have a child lock.AIR QUALITY DETECTION: Currently, particle detection monitors use either infrared sensors or laser sensors. Though the laser sensor is the superior option, the portant thing is that your air purifier has one alongside a display to convey to you the values in real time.This Wyze air purifier has this (laser). It's front facing display not only shows you the PM2.5 numerical value, it also has the color code that indicates air quality: Red-bad air, green good air etc.NOISE: This is where it takes the prize. Most of the competitors have a 24dB sound level at Sleep mode. A few have 22dB - 23dB range. But this baby is even lower than that. Honestly, for now, there's practically no more than two or maybe 3 other brands out there that match this.Now there's a brand I recently stumbled on that claims a 10dB level (I'll believe it when I see it). I just ordered it to see if that's true.Anyway, there's an Auto button and 4 fan speeds. I leave it at auto so I don't need to manually adjust the speed when the air quality changes.I most definitely recommend this brand. IfI could give it more than 5 stars, I would.

Not bad. It could use another "level" between levels 2 & 3 in my humble opinion, volume wise. The first 2 are very quiet, then there's a massive jump in noise level moving up. Other than that, it's a pretty great air purifier. Buying endless filters moving forward is the only real negative, but, like an inkjet printer keeps forever needing ink cartridges, it's just the nature of the beast.

Our children have terrible asthma but we still like to take them places and do activities which means we're staying in hotels sometimes and we decided to buy a pair of these to travel with us and they're fabulous! We absolutely love these filters, they're light weight and they pack up in the car well. Our children have done just fine staying in hotels and rental properties when we have these with us. We have a bunch of filters for home already but I'll be slowly replacing them with these over time. Love these filters!
