Hoover Air Purifier 500, HEPA Air Purifier with Diffuser, Removes 99.97 Percent of Allergy Particles, Pollen, with Fast-Acting H-TRIFILTER Filtration System, Bluetooth Connectivity, White and Silver

The air purifier seems to purify well. Looks OK - the info screen is clear (and can be dimmed).On setup, with the App, you can register the hON app using google or facebook signin. If do you that, the device will refuse to register. You must use an email address and password to sign into the app. I've made the manufacturer aware of this bug - it may be the issue others have been finding with it.I do dislike the lack of fine grained control. There are only 3 modes: "Auto, Max or Sleep". You can't set fan speed (albeit, sleep is low speed, max is high speed).The Auto mode is too sensitive under its "VOC" category. Use of an air freshener at the other end of the house will cause it to think that air pollution is at a dangerous level. As do other cleaning products and it sometimes reacts when someone farts in the room! It appears not sensitive enough on the particle detection. I can smell ash in the air from my woodburning stove, but the increase in level doesn't trigger the purifier to come on (this smell of ash was the reason I bought it). Ideally I'd be able to set thresholds.I do like, that in "Auto" mode, it turns fan off when there is no pollution after a certain time (30min?) (the app says fan is "low" but it is clearly off).So generally positive, but a little bit of finesse would help.

I don’t usually leave a review unless a product is really good or really bad. I am really impressed with this purchase. I am not interested in the humidifier / dehumidifier / Oil diffusion functions. So they may or not be great too but I suspect they would be. I am upgrading from a levoit purifier which has stood me well for a couple of years, and this blows it away (pun intended). Its massively more powerful and is super easy to use and program via the app which connects easily (contrary to other reviews) and via alexa (contrary to other reviews). It you want to use it manually it has clear buttons on top as well as a light ring and other info regarding air quality. Mine is hidden behind a L shape settee and hard to get to so I really appreciate the extra automation and control you can give it.My favourite so far the automatic mode. It just kicks in whenever it senses the air needs a clean and powers up accordingly, then goes back to a minimal quiet mode. There is a sleep function though I’m not quite sure what it does special as the automatic mode seems to put it in a very sleepy state already. I reckon this uses less energy than my use of the levoit as I ended up just leaving that on 24/7 at max, whereas this only pops on and off if its detects cigarette smoke for instance. The downside for this is the device is quite big. My old levoit is say the size of a waste paper basket. This is more the size of a kitchen bin. Its light enough to move but a bit awkward if like me you hide it behind a settee or such.Chuffed with it. Overloaded with features, and as far as I can tell very good value compared to others with similar. Great quality build too. The filters are expensive to replace but thats the main sting with any such device.OK after 6 months of use. The 700 is still working quite well and have had to vac the filter a couple of times…….So I bought a 300 for upstairs. 70 quid off warehouse and had obviously been returned already a couple of times but works great and is in mint condition….. that is until I tried to add it to my hOn app…. Same story as everyone else. Tried everything and every permutation of setting up. Watched videos, googled to hell. It just will not set up on the app despite seemingly connecting to wifi.Its a damn shame as it looses half the functionality being now a dumb device , having said that its still a superb machine and i can park it on auto and forget it. But the hOn app really is terrible. Its awful to use with the 700 for various reasons and the hoover website and support is terrible. I own a hoover dishwasher which is thankfully dumb but that is not their forte either…. Worst dw ever! Hoover needs to get its act together… maybe go back to making dysons.It’s a 5* device with a zero * app…

Was suffering from passive smoking from a neighbor, and bought this, seems to work as expected. A light on the top of the machine lights up in different colors depending on the level of contaminants, strangely the cigarette smoke smell did not seem to register, so I started it on the high setting and then the sleep mode setting. I gave up with the connectivity to the wi-fi when the QR code and product code were not recognizedby the hOn app and just use it manually, I might try setting it up using a different app at a later date, it should not be this hard.

The fanspeedis auto or max.Max is very noisy. Auto is dead quite hardly any aor coming out.It comes alive when cooking for a few minuteand dies down.It wulould have been more useful if it had 3 fan speeds which you could control.

I was almost put off buying this due to all the poor reviews about people not being able to link it to the app. I've had previous problems with some of the early and cheap smart plugs, so thought if I managed to get them to work, this should be ok too.I knew it would need to be paired from a wifi router only giving out 2.4ghz and I do have a separate one just for smart thing like this. I also read to turn off mobile data when trying the set up. I did all the above and still had problems, so I deleted the partially added product from the app and started again. On the 3rd attempt I got it working and now it's paired works perfectly every time.I must say for the price I paid, with all the features it has, plus can be controlled by a pretty decent app, it's an amazing deal. I've had a few other purifiers over the years for around this price, and this one blows the rest out of the water. So much so I'll be ordering another one for the bedroom.
