I've been running this air purifier every single day for about a year and three months or so, had to replace the filter twice, and I've been using it as the primary heat source in my room whenever it gets cold in the fall, through winter, and into spring. It runs every day otherwise on air purifier+fan mode, until I need to switch it back over to the heater setting. It's got a few quirks to it in my situation and where I have it, and I've had to move it around and away from where it probably works best, but it still does a great job for what I need.
So, for some backstory, I live in a house that is about 110 years old, and it just about has old everything; Old windows, old duct work, old unfinished basement, old plaster walls in some areas. I can seal the windows when it gets cold out, at least to the best of my abilities, with shopping bags in the cracks and the seals, and caulking rope on the outside of those to keep more cold out, but they're still single pane windows. I can run the furnace at a higher heat, but I won't get much of it on the second floor, because it doesn't throw far enough. Because of that, I could just use a space heater, but they can be bulky on their own, and I like to run an air purifier too, because being a house that's over 100 years old, it's a dusty shack that doesn't know how to keep clean no matter what you do.
This does both jobs almost perfectly, and it's improved my quality of sleep, breathing, and just life in general. I don't have to fight a chill every cold day any more, the air is cleaner and fresher, it circulates air good on its own on the fan mode, and having a remote for it means that if I start getting too hot in bed, I don't need to get up and go adjust things in the middle of the night. Now, like I said, it's almost perfect, but it has some quicks. For one, in my room, if I want it to be about 73 degrees, I can't leave it at 73, it won't reach that temperature in the room, it'll usually stay at 71. Not bad, but it's not quite enough. If I go higher, like at 75, then it'll get it to 73 pretty easily; and then it keeps on climbing, until it hits about 80 degrees and finally understands "hey, it's 75 degrees, shut off".
This used to be an issue for me, until I realized that if I just kept a second fan on, like the one I run in my window during summer, it'll spread the heat a little more evenly around the room, keeping it more evenly warmed, and actually cause the sensor to realize sooner that it's 75. Well, 75 on the unit, not the room, but it stops at 73, which is actually what I want it at anyways. Maybe this is just because of the room I'm using it in, or the house I live in, or even the location in the room for it; I can't have it where it probably should be, that being a little farther from the walls. Unfortunately I just have too much stuff in just one room, but all things considered I have it working just fine for what I need. All in all, this is an amazing combination unit, and if you need both a heater and an air purifier, this will more than fit that bill.
