All migraine sufferers need one of these!
I have really bad allergies. I also have chronic migraines that are triggered by allergies and certain smells; specifically smoke of any kind, exhaust from a gas engine (car or leaf blower for example), and random foods when cooking. I’m also sensitive to grass and dust; either getting allergy symptoms, itchy skin, or migraines. I’ve had air purifiers before this, but I always avoided ones with disposable filters because of the cost for the replacement filters. My previous purifiers worked well enough, they were just a pain to clean all the time. When I found this one that had the app to go with it I decided to give it a try. I got the unit almost 2 years ago and use it almost 24/7. I don’t vacuum the filters in between switching them out. I simply keep an eye on my filter life in the app and replace it when it’s indicated there. So far I’ve only had to replace the filter once, my first replacement filter still has about 15% life left, that should last another month, maybe 2-3. So for me I’m changing the filter about once a year. Not bad when I’m using it 24/7 and the replacement filter is only $35. I spend most of my time in my bedroom/office (probably about 800 sq feet), so I haven’t felt the need to purchase a second purifier. I do on occasion, when I know there are triggers in the air, move it into the living room for movie or game night. I’ll also take it into the kitchen when cooking smells are bothering me. It never takes more than 10 minutes for the purifier to clean the air in the new room and make it comfortable.I was willing to spend more when I purchased this, but decided to give this one a chance because it was on sale. From the reviews and comments here and on Reddit I think this is as good, if not better, than brands and models twice the price of this unit. The fact that it’s so simple to move around to rooms I’m in, and it cleans the air in the new room so quickly, has made it unnecessary for me to purchase a second or third one.I am finally purchasing a second one for my teenage sons room because he’s started having a lot of allergy issues. He has a cat that stays in his room 90% of the time and he’s a stinky teenage boy. I put my purifier in his room for a week to see if it helped with his allergy symptoms and that stinky boy smell (that’s almost impossible to find the origin of), and unsurprisingly it worked just as well for him as it has for me.I can’t say enough how much I especially recommend this to anyone with migraines. Smell sensitivity can be extreme for some people during a migraine attack. Since having this I have never not been able to sequester myself next to my purifier and at least get relief from that part of the attack. Even beyond the smells it works great as a preventative allowing me to open my window at night for cool air without the allergens triggering a migraine.If you’re on the fence with this one I suggest going for it. It worth paying a little more if it’s outside your budget, and it seems to be just as good, if not better, than units in the higher price point (according to those who have both). The filter replacement cost is not nearly as much of an issue as I thought it would be. $35/year is a very small price to pay to be able to function without a bed ridden migraine.

Absolute value for the price
I've been using air purifiers in my house for at least 15 years now. Every room has one, and it has kept me from having to really dust. Being a single father for most of those years, until my kid graduated and moved out a couple of years ago, not having to do a lot of dusting is a high priority for me...All of them are way oversized for what I need, since I have large smart ones in each bedroom that claim the ability to support like 1500 square feet. But I like the smart, wifi connected ones. I also like the ones with the auto sensing feature so they can adjust their own speeds as needed. So I went for features rather than sizing correctly for each room.Thus, when it was time to get another, and I looked around, this seemed to be a good fit without getting models that cost way too much. I have an Air+Health, and an Aeris, both which are like 3 or 4 times as expensive. And neither of which has ever justified that cost in my experience. Especially now that Aeris was bought out by iRobot and the app won't even work anymore... One more reason to go this route.I got this one a day before I also grabbed a Core 200S for my bathroom - the only one I have that is not capable of auto sensing.This one is dead silent on auto. On speed 1 of 4, it's a very quiet fan noise, even from 5 feet away, which is how far it is from my dining table chair. 2 is not much worse, and even 3 is more than acceptable. 3 sounds like many other ones I've seen would be at a lower setting. 4, of course, is loud, but again, it's loud compared to itself. Compared to, say, my Aeris, Winix, or my Air+Health purifiers, this one has the least obnoxious sound level on the highest setting.I like the ability to schedule things. I let it run at a higher level at night while I sleep since the noise will not bother me at the total opposite end of the house. And even if I did her it, at that point it would be white noise, which I often sleep to anyway due to obnoxious neighbors.The auto setting seems to be spot on with the other ones I have that cost three or four times as much as this. I really never notice it going up - until I cook burgers on the stove. Doesn't matter what else I do with ground beef, tacos or anything else, nothing cares. I cook hamburgers? Suddenly the purifiers in my kitchen, dining room, and great room (big open concept here so these three rooms are one large room that's half of my house) all spin up, show red and are doing their best to cope with whatever it is that my hamburger cooking is doing to my poor indoor air quality. And this one does not lag behind or anything. So you're not getting a lesser quality detection on this one simply because you are not spending such a ridiculous amount.My only real complaint is that the display is so recessed on the top. So if you're sitting across the room you have absolutely NO visible sign of status. And if it's on auto you can't even tell if it's turned on or not since it's so quiet if it isn't sensing something in the air and cranking up the air filtering.But the app works, unlike the Aeris ones now, and the unit is unobtrusive unless you REALLY make an effort.For the price, you can't beat it. And for the price, it beats ones that cost several times its cost.Update - I threw out the thousand dollar Aeris since the app stopped working, replaced it with this. Now I'm replacing two Winix AM90's that worked fine until recently, and are having app issues of their own. One I had going without issues for about 4 years, the other was just pulled out of the box at the same time I ordered my first one of these. So I'll end up now with my home having 5 of the 7 air purifiers in it all being Levoit...
