Xiaomi Smart Air Purifier 4 Pro and VIOMI Smart Air Purifier Pro UV REVIEW

There are so many air purifiers in the market! And the xiaomi is one of the more well accepted brands in singapore for two reasons. The aesthetics and price point. I will share some of the features and my opinions in the video. And why I prefer the Xiaomi Smart Air Purifier 4 over the Pro versions.

The 4 is a good choice, but you can't remove the grill to clean the fans like the 4 pro. If you watch videos, you'd see people having a fit because of the fans gathering dust that they can't clean off, so I think overall the 4 pro is a more solid choice in the long run.

[@roberthaydn837]

What are you saying bro? If you go on the website it literally says the 4 and 4pro have removable grills

[@Angry-Lynx]

yes he confused with lite version which doesnt have that removable grill on top, they have lot of models so its easy to mistake@@roberthaydn837

[@kiyoponnn]

The sweet smell could be from ozone produced by the negative ions. Try switching that feature off to see if it helps

[@Angry-Lynx]

also i think its very immportant to remember about airflow. i dont think purifier alone can clean whole room air if you dont have something that creates airflow; i mean purifier standing in room corner probably won't clean air on the opposite corner of room unless you use it on max setting that will create airflow in whole room; you can use just regular fan set somewhere in room to assure air in whole room mixes for best result ; its not purifier fault, its just basic physics ; air NEEDS to be moving in room

[@Systemat]

Great content as always. Just got the Xiaomi Purifier 4. Integrates well with Google Home too; able to select the different setting from Manual to Auto on the screen. Thanks!

[@fxrisxmxli]

Most in depth & best review I can find so far! Thank you!

[@Poraqui]

You have to be mindful that running this (and most) air purifiers on auto mode delivers sup par purification results. It might be due to the accuracy of the built in sensor, the way that it is coded to measure air quality and how it cross-references measured air quality to its own embedded quality chart (in some countries 35μgr/m³ PM2.5 is acceptable air quality whereas in others it's considered poor) conducing to not ideal activation and deactivation purifier times. And this might be one possible cause why the air purifier is not attaining the results needed in your daughter's bedroom. On auto the level of purification might not be good enough for her needs. The way to potentiate this and others purifier performance is to use rules. For instance, in the app set: if PM2.5 is higher than 20 then switch to manual mode. Manual mode can be set to maximum level. Then you can also set another rule that when PM2.5 is lower than 5 to switch to Auto mode. This rule is necessary because after 2-4h on manual mode the mi airpurifier will switch to auto without it. Hope it helps.

[@SuperMan19867]

also the sensor to much close to the wall xiaomi manual said need at least 20cm\6inch from the wall

[@N1rOx]

Awesome post, I've set mine to this. Thanks!

[@Angry-Lynx]

yes we in Europe have much higher standards for what is considered good air quality; btw thats why there is pm2.5 indicator, so you can decide for yourself if you need more 'power' ; also i think its very immportant to remember about airflow. i dont think purifier alone can clean whole room air if you dont have something that creates airflow; i mean purifier standing in room corner probably won't clean air on the opposite corner of room unless you use it on max setting that will create airflow in whole room; you can use just regular fan set somewhere in room to assure air in whole room mixes for best result ; its not purifier fault, its just basic physics ;

Thank for Rezession.... greetings from Germany ❣️

[@Angry-Lynx]

i choose xiaomi air purifier 4 for my caravan because its already big and expensive, lite version would probably enough for my small room but since i could afford better one with more airflow and ionization then why not. pro version is even better but its just to big for my caravan, its huge. my main concern is reliability, pm2.5 sensor accuracy and overall quality, since its known Chinese company. i considered that against levoit core 400s thats way less popular, its smaller, same airflow, looks better but i read abour noisy motors in them a lot of people complain and that bottom closing housing is made with cheap and weak plastic and could be easy to break, that eliminated it for me, as i need sturdy stuff, im not good with delicate stuff ; overall not big choice in this price range, all Chinese purifiers, if you want something higher quality for that price it will have very weak features, like half airflow, no even mobile app etc; and since most people are happy with xiaomi i went with that, well see if its worth anything, itll come yesterday ; cool video, i love your accent cheers ;

[@monarch8188]

Thanks for review! It was helpful for me. I would choose 4 Pro

[@thk38]

Thanks for ur review, I wonder if the Smart mosquito repellent features actually work????

[@abdsalamelkhamlichi6677]

[@bokbokeh]

Thanks for the informative vjdeo!

[@JustHumor]

thats a very good review, i am planning to buy Viomi air purifier, but filters are hard to find, can you please make a video or suggest if we can use Xiaomi airpurifier filter in viomi ? if yes then which model xiaomi air purifier filter is compatible with viomi air purifier ? thank you

[@friend116]

Where i can buy the viomi filter , do xiaomi filter instead??

[@gabrielitos13]

Any luck on finding a suitable filter replacement from Xiaomi for the Viomi purifier?

[@rougestan]

Doesn’t state if it uses a true hepa filter which is the basic gold standard for air purifiers

[@s-u-m-a-i-r]

in the manual it says don't put that air purifier close to wall, it must be at some distance to work effectively?

[@1986Redfield]

Negative ion generator is really work? Smells like in the woods? Fresh?

[@awh85]

where di you get that from? i want. the 2 to 3 pin plug converter.

[@AzfarHashmi]

is the negative ion thing always-on or switchable?

[@Jamesx9]

Any top 3 push pull digital lock you recommend under 1k? Thanks :)

[@nenadpiperkoski6523]

Does it clean the dust?

[@user-eq3kj8mj2g]

Hi, did you try Sterra air purifier ?

[@bentom2993]

Hi Does the Viomi device need the same filter as the Pro 4?

[@madsncakes]

Don’t think it’s the same.

[@GostFlash]

Anyone knows what alternative filters I can use for viomi?

[@user-ow8fh8tx6y]

Do u need to use VPN to use miHome and Xiaoai?

[@1MW9]

electricity consumption?

[@madsncakes]

honestly it is very little... I would say same as an average fan

[@ptxarptxarov3830]

What is suite smell ?

[@JustHumor]

i think she means sweet

[@wretchedworm]

really got catch mosquitoes?

[@madsncakes]

my house is sealed with mosquito nets and I hardly open the windows so I can't demo this

[@wretchedworm]

@@madsncakes thanks. is the viomi filter the same as the 4 pro? i just got the viomi in the end because of the uv and was thinking of where to get the replacement filter

[@JustHumor]

@@wretchedworm i am also thinking to buy Viomi Air purifier, the question is which xiaomi air purifier filter is compatible with viomi? because viomi filters are really hard to find. if you have any information please share thanks

[@kyiphyushwe]

I am looking to get an air purifier because I have 2 cats and a toddler but my living room is open plan meaning the living room opens to dinning room then to the kitchen so it's a pretty large space (around 500 sqft at least) and I usually keep my balcony door open instead of running the AC. I can't decide between xiaomi air purifier 4 and 4 pro. I want 4 cos it's smaller and probably smaller to move it around in case I want to use it in the bedroom. I want 4 Pro cos it is more powerful and probably can handle the open plan layout of the living/dinning/kitchen. So confused still

[@madsncakes]

I like the 4 for its size. Like you said, so you can move it around!

[@AhmadNazirAfiq]

Hopefully a filter comparison too. I have lots of cats so not sure which is the right filter to get.

[@omegatextilome733]

All brand are same, the filter is important base your choice of Filter Minimum H13 True Hepa filter and above, and CADR must be as much is possible bigger. That is rest is useless extra

[@dyako1588]

I have cat allergy does this help me ? As I have a cat

[@madsncakes]

I doubt sooo

[@giovanniturco6428]

I am going for the xiaomi air purifier 4 because it’s small just checked on Amazon UK 🇬🇧 not available shame

[@madsncakes]

Try aliexpress

[@nanthiny8634]

Actually ah you would not be helping your daughter with her allergies by using the purifier , might to an extent exacerbate it when she goes into environment without purified air (aka outside of home) the flare up may be way worse. Just sharing, nice vid btw !

[@joshua01]

Actually…Indoor air can be 100 worse than outdoor air. Indoor air can have buildup of mold, bacteria, viruses, voc (cleaning products, etc) and depending on whether you have plants or pets, pollen or pet dander can all be found in indoor air. So purified indoor air is actually really important as with most people this is the time they spent most and the air you breathe matters. In early childhood, poor air can lead to asthma and a host of other problems. You’re point has a different perspective but its not a way to justify breathing bad air.

child room without windows? ok :/
