Many reviews picked this one not high exhaust function though
It’s a pretty good fan and I’d like the fact that it has multiple settings however the strong settings, the highest settings not very high and so if you’re going to use this as an exhaust fan or a small space, you probably should for getting something a little bit more but if you just need it as an every day, this is OK this is a great little quality fan but if you need to do heavy duty work, you should find something else. Cost point is good airflow is good but the power is low even on the high setting if you were going to use it for exhaust. But it’s really great for at night if you’re just using it in your room, the sleep setting is really comfortable and it’s quiet so you can get to sleep without hearing so much noise and having a cool breeze.

Yeah, there’s a hum…
Needed to replace a previous fan from a different manufacturer. That fan did not last that long until bearings in motors started to go after less than a year. This model had the requirements I was looking for- intake/exhaust WITHOUT having to turn the whole thing around. It also had good size fans for a good flow rate, and would fit easily in a window. There was one ‘semi-major’ downside, which I will get to. Airflow/Fan noise is pretty quiet- however the fan motors do have some hum. Pretty standard for an electric motor at a relatively budget price point. It isn’t distracting in my situation- it is in a kitchen window and not noticeable from any other room, so that’s a moot point. It is more powerful at the medium level that the last one was on ‘High’, so I don’t need to run this one as hard, which keeps that hum down as well. One little problem is that it is JUST a bit too narrow- even fully extended, for that window. So when it is running it would buzz a bit since it vibrated against the frame. No big deal, a strip of foam on each side fixed that as well as any draft from outside slipping past the edges.The “Semi-Major” issue is, what I think is a design flaw. The AC cord exits the unit WAY TOO LOW. Put it in the window track, and there is a conflict with that cord. It just doesn’t fit right when trying to settle the upper window against the top of the unit. It tilts forward which then means it won’t fit in the lower track very well. Again, I needed to find a strip of dense foam to raise the fan up a bit so the cord clears the bottom track and will sit vertically. (I will take a photo and update in a bit, not at home at the moment)Remote is a bit cheap looking and feeling (no batteries supplied), but it DOES have one. Probably never use it, but hey… Otherwise it is a good replacement for the previous fan at a reasonable price.

Has wifi
Updated review:I’ve gone back to using my original fan. The Bionaire one. You’ll see it if you search for it on Amazon.So here’s a quick comparison and why I decided to go back.The fans on the bionaire can be louder than this fan, but the hum of this fan is louder than either fan while on low setting. I had hoped I would just get used to it, but it actually gets more annoying over time.Voice assistant function is basically pointless. I very rarely turn my fan off or on, or change speed, after all. Most of the time I want to change something, it’s the air direction, and that has to be done by app, which is less convenient than a traditional remote. In order of convenience, best to worst: voice assistant>traditional remote>walking over to the fan>phone app.That all said, it could be better in other applications like, if it was in my attic or garage where its extra inconvenient to get to and I don’t care at all about the hum, then this would be superior to the bionaire.Original review:Bought this for it’s wifi connectivity mainly. Aesthetically not very nice. Looks like cheap plastic, all one color, bad design, looks fragile. Blister buttons are covered by big cheap looking stickers. Mine has bubbles in them.Also, it hums. At it’s lowest speed, the hum is louder than the actual fan.But. It does connect to wifi. With the proprietary app, you can control all the settings. With voice assistant you can only control speed and on/off.I am on the fence whether or not I will keep it at the moment.

The sides could extend longer. Moves hot air quick

 

I purchase this Comfort Zone Cz310R Twin Window Fan because I wanted to get some fresh air from outside into my house and make a draught or some nice cooling breeze I saw it on Amazon.co.uk so I thought everything else I buy on this website is usually made to use in the UK I’ve up by batteries or plug sockets or television’s anything really so I trusted Amazon and I usually always get what I purchase we keep having heat waves here in the UK so I finally had enough and I wanted to get a window fan I looked on Amazon and this one looked like it was the best I didn’t really look at the reviews I was just excited by the picture and what you can do then I purchased “Comfort Zone Cz310R Twin Window Fan” and I was excited because it came earlier than expected but when I open the packaging and got the product out I notice something unusual the plug socket was not made for the UK after looking it up I realise it’s for the American use I’m not quite sure about Europe because we have different plugs there too but obviously I cannot use it in the UK I emailed the product supplier and they said they apologise and I could send it back and if the product I’m sending back I had to pay for to return it cost more than 20 pounds I could get my money reimbursed I went down to my local post office to send it back and they said becausr it came from America and it was so heavy it will cost £170 just to return it and I bought this for £95 so obviously it wasn’t worth it. I had to look up on Amazon a plug socket what can do USA to UK plug adapter an I purchased it and hopefully it will arrive tomorrow obviously I can’t be sending it back because it costs far too much compared to what I paid for it. I will not be buying from this supplier again it’s just way too much hassle to return it an too much hassle just to look up its mistakes when I should be enjoying my product.USA to UK Plug Adaptor/Chinese to UK Plug Convertor
