Shark 3-in-1 Clean Sense Air Purifier, Heater & Fan, HC450, Grey

This unit is much bigger than I expected. Even though I always check product dimensions, I somehow didn't anticipate a slimmed-down version of R2D2. I also wasn't aware that I was buying a refurbished unit, even after reading all the specs and product details multiple times before making my purchase. That may have been my oversight, and it's working like a champ regardless, and the discounted price for a refurbished unit was helpful. My home smells a lot cleaner, and I'm trusting that the air is actually cleaner, too, because I live in an area with 24/7 vehicle 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 the smell wasn't from the unit itself. It's the actual new, original filter that 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. When it came time to replace the filter, I was unable to find actual Shark brand replacement filters, so I had to buy aftermarket filters, which have no smell at all.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 on 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 would have caused the initial readout to be lower. But despite that, it's been working fine since and appears to now be showing 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 more or less accurate data. The filter also efficiently rids my apartment of cooking smells from adjacent apartments. 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 digital temp gauges in my home, and they all show the same indoor temp as on the Shark unit. So, overall, I'm very happy with the air-cleaning function and fan function on this unit, and the few times I've used it in heating mode, it quickly warmed up my good-sized, high-ceilinged living room. The oscillation function is handy and swivels silently. I've come to really appreciate this this multi-function air purifier/fan/heater, and considering it's a refurbished unit, it's been reliable and efficient, and has more than overcome my concern about its not exactly unobtrusive presence. That said, I've had this unit for just under an year, and haven't used the very effective heater function often enough to determine how costly it would be to use more frequently in the winter months.

This is a must have I actually bought more !!!This has really helped my heating and air-conditioned bills out !!!It circulating is perfect for the whole room or if you just need it on you you can stop it from rotation.The air is cool when you need it and warm when you need it !!I live the heated option because when my nephews come in from the pool I can turn it on for them LOLOr in the winter after playing in the snow I can have it ready with hot coco for them !!Even on rainy days it's perfect I just absolutely love it .Or if you want to get a bathroom nice and toasty for soaking spa experience it's perfect for that too .Or if your racking leaves in the fall and you have a sunroom you can use this so you don't have to keep running in and out .I also love the settings 1 to 6 it really blows out alot of air !!! So much so that it can even dry your hair if you want it too LOLI love waking up and seeing the 100! Blue circle knowing all night long I have breathed the best air possible and I don't wake up all stuffed like I used too and no more headaches either !!! This is why I have one in every room now !!! It's definitely an investment but we'll worth it !!!Even fixes the air in the kitchen when you accidentally burn something it quickly cleansing the air and you can watch it go from red circles or yellow circles back to blue circles providing clean air again .

so when I first bought this, I loved the idea of getting rid of multiple devices for one especially as I live in a home about 250sqft so every inch matters.However I was starting from 2 stars as it arrived with dead batteries in the remote and without the remote there is no real way to control any of functions other than on/off and not keen that if something ever happened to the remote it will become useless. So that automatically made it so I thought less of it.Once I got batteries, still only gave it 2 stars as it didn't feel as if it had any fan power, the same as some other less than stellar reviews. However, stupid me hadn't taken it apart where the filter was to remove the plastic around the filter which is why it felt like it had no air flow. Once that was fixed it went up to 4 stars (still loss of 1 star for being fully remote).However 24 hours later it earned it's fifth star. I live in a detached garage turned tiny house. However the owner's didn't exactly make things to code, and it gets musty smell and my sinuses are always having issues. Less than 24 hours and my breathing was MUCH better. Still have small issues due to allergies, but mainly only after I've been outdoors or when smoke from the fires here in Cali get too bad. But it's enough of an improvement it makes up for the remote issue.

So, I wanted this for quite some time and waited until it was on sale. I like it as I do feel it helps clean the air inside the home. However, one of the main features I wanted it for was the heat. It will not replace a space heater. When you first turn on the heat function, it heats up and does its thing. It didn't seem like it would maintain the proper temperature though. The fan speed goes down and will go back up when it tries to get back to the temp you set it to. Still, I do love that it cleans the air quite well.One thing that I did have happen was when I plugged this in for the first time, I plugged it into the power strip I had that was older and it instantly blew the strip. My bad. Now I know to plug it directly into the wall outlet. Lesson learned.I guess I should mention that it might be a little heavy if your smaller but the weight isn't too bad, it's more awkward to carry. And it is pretty quiet on the low fan speed.

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.

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

I’ve had this nearly two years now and it is my favorite purchase to date. Auto detects odors instantly and cleanses right away. I’ve never slept better and no longer wake up stuffy. Would 100% recommend. I use it daily and on auto during the night! Filters are easy to pop in

El mejor difusor que se an fabricado para mi un 10 de 10 tiene buen alcance y abarca bien los espacios llevando el aroma a casi toda la casa y la mía es grande créanme .

Nada que pedirle a dyson, se siente muy diferente el aire y sin olores! Lo recomiendo en espacios pequeños como recámaras

Just bought this 3 in 1 Purifier with heater & Fan for our bedroom actually,(change of plans lol)! An absolutely Great Purifier from Shark! The heat is not a joke it keeps us toasty warm,the cooling fan cools fabulously if that is what you are needing. The air purifier mode makes short work of restoring clean air when it is required. It oscillates. The remote is so great,no jumping out of bed in the am. to warm the room before getting ready to start the day. We find it quiet enough to not disturb our sleep,also the light on the info dial can be turned off or dimmed at night while sleeping. This item makes me happy! A 10 out 10 Highly recommend! We also have a smaller unit from Shark in our Family room also 10/10. :)

Works very well! Much better than the previous popular brand I had.

After 8 months, the ceramic heater will turn on and the fans do not, that is a FIRE HAZARD.And when contacting Shark support instead of giving me a replacement heat+purifier, they just sent a purifier, which I do not need. And to top it off, their support is so slow at responding (10+ days) and want you to waste your time on a video call with them instead of just answering their emails.Video shows literal smoke coming out of the unit.
