Toshiba CAF-W36USW Air Purifier with UV Light Sanitizer - Eliminates Smoke, Dust, Odors, Pollen & Pet Hair - Ideal for Home, Office & Bedroom Use - Black

I love this filter, but not so much to begin with. Initially I had both the blue and green lights blinking and it wouldn't connect to anything. The filter worked fine for what it was supposed to do with the manual buttons, but once I settled down, it only took a few minutes, turning on a light and unpacking a few brain cells to get everything connected and working the way it was supposed to.I'm sure all this was included in the setup directions, but being male and moderately capable in technology, my wife says I tend to avoid those in favor of having challenges to solve so I can prove my worth around the house. I think it's more that I just hate wading through useless directions telling you 78 ways to not use your new appliance that never crossed my mind. Nope, taking my air filter into the shower wasn't even a consideration, but I'm sure there's a really entertaining story in there somewhere.On startup, the blue light was blinking which supposedly means that the filter needs to be changed. Not likely just a minute or so after initial startup. The solution is to hold that button down for a few seconds till it gives a very faint beep. Don't hold it down any longer than that... as with many things, more than enough isn't necessarily better and might actually hold up or reverse the process.That left the blinking green light to solve. Again while the directions said hold it for 3 seconds, I held it for about 10 seconds just to be sure. At that point it beeped numerous times at me and as it turns out, that was the filter's way of saying, "knock it off". Nope - wouldn't connect to Alexa and the app just gave me error messages. So I went back and just held it down till it beeped once and like magic, then it connected.With everything working, let me tell you about the number of ways that I like this and how great it is, in no particular order.1) This pushes as much air as my old air filter but only weighs about 20% as much, meaning it's easy to move and takes up about 1/3 the floor space.2) It actually kinda looks pretty slick and fits in with just about any decor.3) The Alexa function is spanky. On/off and increase/decrease speed. Also turn on/off UV mode. You can also create a routine with this but I honestly don't plan on turning this thing off till 2020 his in my rear view, and I'm not sure about then.4) Since beginning operation, our required dusting is significantly less. Since we have allergies to dust, this has made everyone feel better. Also of note, dust is a known pathway for various pathogens so it makes sense that reducing the dust could improve health and the immune system less encumbered.5) I don't burn things in the kitchen very often, but general odors from cooking are quickly reduced while running this filter on high, and guests say they can't tell what we had for dinner just a couple hours later. I expect fish fry night may put that to a test and could mean I'll have to change the carbon filter much sooner.6) Super quiet. All you hear is the sound of the air going through the machine. On low setting, you could have this right next to you and not have it interfere with a conversation. We have ours on the far end of the living room with seating in the middle and the television at the other end. On high speed, there's no interference with television sound.There is a claim in this page for [UVA sterilization]. I have serious doubts here as I've not been able to find any corroborative information and in fact several sources say that UVA doesn't sterilize anything. Also, even when UV does sterilize, it depends on how long the pathogen is exposed. This filter pushes air through at a very good rate, and even on low speed, I can't see that anything going through the filter would be exposed to any UV light for more than a split second. Sounds like a gimmick to me, but take it for the opinion that it is and welcome information that tells me how they can accomplish this task and independent labs that would have verified this is what is happening.
