Xiaomi Smart Air Purifier 4 Compact - Trusted Review (+ Smoke Test)

[@AirPurifierFirst]

Buy the Xiaomi 4 Compact on Amazon: amzn.to/3gL6XpF If you have any questions, please feel free to comment below, and I will do my best to answer as soon as possible! 😊

[@TrevorPhilipsBro]

I got one in my room when our baby came. I like it so much I just ordered another one for my office. One thing I will say, it is acurrate about the air quality.

[@tl11316]

I have also a one year old baby and I have just ordered it. How often do you change the filter? Can you feel the difference in the air quality after using it? :)

[@MithrilArtsandJewelry]

i just ordered this and will get it in a couple of days. My neighbors are heavy smokers and it's quite dusty here in the area that i live in. So I always get migraines from the smoke especially at night and have to turn on the AC for it even if it's cold. Hopefully, this works out. Thank you so much for the reviews!

[@kelvinvera5777]

Hello, how has it been with the equipment you already purchased, does it help to have cleaner air?

[@MithrilArtsandJewelry]

@@kelvinvera5777 hi! I've been using it for a week and I would have to say it has helped a lot. The first night I've had it, I slept so well and didn't have a headache the next day even if my neighbors are smoking the whole night. It took me a while to figure out where I should place it though. So for now, especially in the evening, I keep it in my kitchen since it's nearest to the front door. Nowadays, I don't smell cigarette smoke as much and I'm really happy about that. I got it for 68 usd where I'm at and I think I'll probably buy another one next time or I'll get the bigger one for my room when I have extra money.

[@cptnmrvl1357]

hello how's your experience using the product?

[@Metdaex]

Would love to see comparison between new series 4 of Xiaomi's air purifiers and how they stack up against last series and against competition. Keep up the great reviews!

Thank you for the great video! Would you suggest it for a flat's kitchen for eliminate cooking smells, if any other solutions are off the tables (of course filter needs more frequent change)?

[@Mzimasi]

Hey! So I own one of these and live in a small apartment. So when I cook, the smell travels through the house. It instantly picked up the poor air quality after cooking and ramped up the fans for like 3 minutes until it stopped. It did eliminate the smell

[@yildiraykomurcu]

How does it perform compared to Levoit 300s ?

[@AirPurifierFirst]

I see many likes on your comment, but the problem with why I don't have the answer is that I haven't tested the Levoit Core 300S yet. I will do my best to buy the Core 300S asap and then test it and compare it to the Xiaomi.

[@feelgeorge]

@@AirPurifierFirst can't wait for that video. We all want to see the Xiaomi air purifier 4 compact vs the Levoit 300S

[@Marc_AD]

Very insightful review. Currently the compact is available at a shop near me and not the 4 lite. What would I be missing when buying the compact over the 4 lite? Thanks!

[@jeremylim123]

honestly there is not much difference between any of the models besides covering a larger area. The 4 and 4 pro just has a few more extra features which personally i feel you wouldn't require for a home setting.

[@7prudent]

​@@jeremylim123can you vacuum the filter of the compact one?

[@jeremylim123]

I believe so. have been doing it once every 2 months with no issues though it is still safer to change your filter at least once a year or when prompted if you want the proper protection against airborne pollutants. Vacuuming the dust that collects on the outer layer only helps make it easier for your air purifier to function but it does not properly remove the trap particles in the inner layers of the filter which the vacuum is not capable of doing. @@7prudent

[@7prudent]

​@@jeremylim123thank you! One more question. Does it also work on mold in the air?

[@jeremylim123]

@@7prudent air purifiers in general are not very effective against mold in the air. It can trap mold from the air in the filter but it does not remove the mold spores which does not solve the problem completely. If mold is a concern, you should get a dehumidifier as well. Moisture and a humid environment are what make the mold thrive. To fully protect yourself, invest in an air purifier and a dehumidifier. However, if your room has air-conditioning, you can use that to be the dehumidifier although it may not be the best energy cost-wise. If you're not encountering any issues with mold presently, occasionally using your air conditioning should help to prevent it somewhat.

[@sabrigasmi4679]

I have an issue with this product. The air quality indicator keeps switching from "very good" to "good", causing constant mode changes when set to automatic. I've cleaned the sensor and checked if it was related to a pollution issue using another device, but no luck. Am I the only one experiencing this problem?

[@MamaMia-mf7ei]

No

[@7prudent]

How can I learn if it really does not have an ionizer? The official website has no informations stated about it.

[@Nonameforme12355]

Have you found any information yet?

[@muliadyamrose]

How about Xiaomi smart scene, can we do something like; If the air purifier detect bad air quality, it can trigger something or other devices... ok thanks

[@gtamyths96]

You should make a comparison between this and the Levoit Core 300, they look similar

[@AirPurifierFirst]

Thanks for the suggestion, I will!

[@Katarina-vh2wq]

Is it safe to use around parrots? Should we choose LV-H132 instead?

[@Katarina-vh2wq]

For everyone who asked, Xiaomi support team said it is ozone free and does not produce ions, since that was our biggest concern for our parrots. We emailed them and this is what they said in response.

[@yeng9241]

Which one is better this one or smartmi air purifier p1?

[@makunpi]

Hey, i just wanted to ask, does it work for places with high polution? I live in the center of a huge city, will it work or do i need another device with different filters?

[@gonkong5638]

The 3H is almost beat the 400s.

[@BuleCintahIndonesia]

Good review but it would be helpful if you could test the accuracy of the sensor. If I put mine outside on hugely unhealthy day in Jakarta, it says the the air quality is good or moderate at worst.

[@aliffdanial7924]

hi. i have the same issue, have you solved this issue? If yes, can u tell me how?

[@BuleCintahIndonesia]

@@aliffdanial7924 Hi, I think the only way is to switch to manual mode and turn it up as possible. The sensor is useless.

It's not recommended to use an air purifier in high-humidity areas. However, placing a Xiaomi Humidifier in another corner of the room wouldn't make such a large difference in humidity, so I believe using those two devices together would be fine.

Dam. I was considering buying it...I have pollen allergy too. but it didnt work at all? PLEAse respond !! And where do u live?

[@AndreasRP.]

@@RITechNews I live in Denmark and it didn’t work for me at all. I left it running at full speed for an hour and then left it at sleep mode the entire night. When I woke up I still had itchy eyes, I proceeded to let it run throughout the day but I would still get itchy eyes every now and then like I used to have before I bought it, therefore I decided to return it. Note that throughout the time I had the machine, I put clean sheets on and had my window open for max 10-20 minutes at a time to avoid getting too much pollen in my room but it didn’t make a noticeable difference to me or my allergy. It’s not dusty in my room as I clean it daily because of my pollen allergy. I read somewhere that if you want one that truly helps with allergies you need one with a true Hepa filter, but they are quite expensive and big, so for now I guess eye drops will have to do for me. You can always buy it and return it if it doesn’t help you.

I am also new to the purifiers so that's all I know so far. I will also get one of them =)
