This is a great 3 in 1 for heat and cook with air purifier. It’s great in my office and heats or cools the room during the day. Auto off and on to keep a consistent temperature. plus purified air!!

I'll review this from a few of the most important standpoints. Size: - It's definitely not small! That being said, before I had a heater and air purifier separately and when stacked this is smaller than those two together. I think it's important to recognize the combination. The footprint itself isn't huge, but it's tall. Sound: - Fan Mode: On a moderate speed of 3 (out of 6) it's still very quiet. On 4 it's pretty noticible. Anything higher it's kinda loud. It's moving good volume of air though at those speeds. I find that even at the moderate speeds it was sufficient air for my office. - Air purifier: A little more quiet than the fan modes at the same speeds - Heat: Again on speed of 3, but it's much much louder. I don't find it louder than my previous infrared heater. Air volume: Good in all modes. It can really put out in the high modes at sacrifice for quietness. Oscillation: Nice to have to more evenly distribute airflow. Remote: I like that it docks in the top of the device with magnets, but feel it's a missed opportunity to have it charge as well. At this price point, it would have been a nice value add. Overall: I think this is a solid unit that would do well for use in a variety of rooms. The lights are controllable so would turn off in a bedroom, and I could see the sound being a good white noise for folks that like that. I appreciate the variable options between heat and fan and really looking forward to that in places like my office that fluctuate wildly.

First, this unit is much bigger than I expected. I always check product dimensions, but somehow didn't anticipate a slimmed-down version of R2D2. What I also didn't expect was that I was buying a refurbished unit. I read all the specs and product details multiple times before making my purchase, but did not see any mention of the item being refurbished. That may have been my oversight, and regardless, it's now working like a champ, and my home smells a lot cleaner. I'm trusting that the air really is cleaner, too, because I live on a street with lots of traffic that generates unhealthy particulate matter. Reading other reviews, I was concerned about the product off-gassing an unpleasant chemical smell, but it turns out that the smell isn't from the unit itself. It's the actual filter that smells and emits a toxic fug. When removing the filter from the unit to take off the plastic it's sealed in, the smell was released, and when I went over to check if the unit itself smelled as well, it didn't. But the filter smell dissipated fairly quickly, so it wasn't an issue. Immediately after turning on the unit for the first time, at the highest fan setting, the readout was showing the air quality at 100%, which was highly unlikely, considering that I live next to a very busy street, and hadn't been using my other air purifiers for a while. And I would have expected that the initial toxic filter smell alone didn't cause the initial readout to be lower. But despite that, it's been working fine since and appears to now being giving accurate air quality and temperature readouts. It's said that one of the most common household pollutants is generated when we make toast. I was happy to see that when I make toast, the Shark air quality readout lowers almost immediately (even though I always use the kitchen extractor fan when toasting bread) , so it seems that the air quality gauge is now providing what I assume is accurate data. The filter also efficiently rids my apartment of cooking smells from adjacent units. It does it so well that even if that's all it did, I'd be happy enough to have bought it for that alone. I have other supposedly high-quality air purifiers, but they couldn't cope with cooking smells very well at all. The temperature readout on this unit is always correct. I have several free-standing temp gauges in my home, and they all show the same indoor temp as on the Shark unit. So my only complaint is that the force of the air isn't strong enough to use as a cooling fan during hot weather. But that's not a deal-breaker as my very efficient Dyson tower fan does such a great job that it cools even on the lowest setting. So, overall, I'm happy with the air-cleaning function on this unit, and the few times I've use the heat function, it quickly warmed up my good-sized living room with high ceilings, and I never had to have it in heater mode for more than 10 minutes. My only minor complaint is that the air speed -- even at the max setting -- is a bit weak to offer much cooling in the fan-only mode.

Looks nice in my office, functions as it should, and keeps my office smelling and feeling great. The initial week of use it made my space smell sort of like a dental office, but after that just keeps it smelling clean.

AVOID AT ALL COSTS!!! UNSAFE! SHARK DOESN’T STAND BEHIND THEIR PRODUCTS!!! I’d give this less than 1 star if I could. I had this product in my newborn infants room to keep the air clean and keep it warm. Walked in during the middle of the night and the product had a strong smoke odor and air quality in the room was noted at 60%. This machine was polluting, not purifying!!! I called Shark just trying to get a refund because I am going to buy the Dyson (no longer trust Shark products); they were entirely helpful and I had to escalate my case multiple times to get anyone to engage. Obviously I can’t get my money back from Amazon as it’s beyond the 30 days and now Shark won’t uphold its 60 day product guarantee bc I bought on Amazon. Terrible company… They also asked for details about the cord while I was on the phone with them…I’m speculating this is a known issue, which makes it even n more disgusting

This item is very nice. Heats and purifies the air at the same time. I highly recommend this item.

I love it. Had it for about 4 months now, I have a cat, 2 adult turtles and I smoke flower and I can see, smell, and feel the difference. I like the 3 in 1 utility the most and consider it one of my top buys in years. Improves air quality, heats very well and is aesthetically pleasing.
