The Air Purifier 2 has got it sorted in the looks department. It is white and stands tall at 52cm and has a depth of 24cm . This air purifier has three intake vents that’s present at the front, & at both sides. They’re designed in a way that ‘disappear’ as they flow up. Very sliông xã indeed. The Power/Function button is located at the top while the 3 mode indicators are at the side; Auto lớn, Sleep, Favorite.

Setup was straightforward but there’re a few things to take note off. First, depending on where you order the Air Purifier 2 from, it will likely come with a Chinese manual. This presents a challenge for me as I can’t speak nor read Chinese. Luckily Xiaomày has also an English version available. Link khổng lồ the English Manual pdf here.

The most important component; The filter. Xiaomi has 3 filters for you lớn choose which I will menu below. One of them is a HEPA filter and I will first briefly describe what HEPA means. Most air filters/purifiers in the market these days come with a HEPA filter. Depending on which source you’re referring khổng lồ, you will find slight variations of the HEPA measurements. For this article we will refer lớn new European Standard EN 1822. EN 1822 defines a HEPA filter khổng lồ trap 99.97% of dust particles that are 0.3 microns in diameter. Below is the measurement by EN 1822.

Integral ValueLocal Value
 Filter Class Collection Efficiency %Penetration % Collection Efficiency %Penetration %

The filter class description are:EPA 10 – EPA 12: Efficiency Particulate Air FiltersHEPA 13 – HEPA 14: High Efficiency Particulate Air FiltersULPA 15 – ULPA 17: Ultra Low Penetration Air Filters

Filter – Blue Colour (Economic Version)

This was the filter that came with the Xiaongươi Air Purifier 2. It is an EPA (Efficiency Particulate Air) filter that’s able to lớn trap particles that’re 0.3 microns in form size. Essentially you can consider this as the standard mặc định filter.

Economic Version.Filter – Green Colour (Formaldehyde/Enhanced Version)

The ‘specialty’ of this filter is that its designed lớn target Formaldehyde. According lớn the CDC, ‘Formaldehyde is a comtháng chemical that can be emitted from a number of products in the home. Smoking, pressed wood, và particle board have sầu all been shown to be sources of formaldehyde. Higher formaldehyde levels are usually found in newer homes or homes with new construction.’ On the Xiaongươi trang web, this filter is advertised as a H11-grade HEPA filter that filters up khổng lồ 99.3% of 0.3 microns. If we go by the EN1822 standard, you will see that this filter doesn’t meet the HEPA standard today. This is because the updated EN1822 standard has now categorized H11 as E11 making this filter EPA & not HEPA. Granted, this filter was released a while baông xã in 2015 so the HEPA definition would have sầu stood still then.

Formaldehyde/Enhanced Version.Filter – Purple Colour (Antibacterial Version)

This filter has an antibacterial layer can trap and kill dust mites. It’s able to trap 0.3 micron particles but it doesn’t mention whether its a EPA or HEPA filter.

Antibacterial Version.Filter – Which lớn choose

If you aren’t fussy about filter grading, then you have sầu 2 options; the Economic Version (Blue Colour) and the Antibacterial Version (Purple Colour). Get the Economic Version if you want a standard filter & Antibacterial Version if you want something that targets bacteria and dust mites. If you want a HEPA filter then the Formaldehyde/Enhanced Version (Green Colour) type is your choice. It’s worth noting that all 3 filters come with an activated carbon layer.

Usage & PerformanceUsage và Performance – Air Quality Index

The app’s interface is minimidanh mục & straightforward. Once launched, you will be able to lớn see environment conditions such as Temperature và Humidity. Also recorded is the Air Quality Index, Filter Running time (days and hours) and the amount of clear air delivered (cubic metres). All these are made possible by the PM2.5 sensor that’s embedded in the Air Purifier.

You’ll be able khổng lồ see the air unique recording.Other environment conditions are also recorded.

Usage và Performance – Aukhổng lồ Mode, Sleep Mode, Favourite Mode

Using the Air Purifier 2 was simple. Once turned on, you can either press the physical Power/Function to lớn toggle between modes or select them via the Air Purifier 2 tiện ích. There are 3 modes provided in the app; Aulớn, Sleep & Favorite.

Aukhổng lồ Mode

The tự động hóa mode automatically switches modes according khổng lồ air unique condition. Which means if it detects that the air quality is getting worse, it will increase its work rate.

Sleep Mode

Sleep mode should be used if you want a quiet night’s sleep. Which means it goes inlớn low setting to minimize noise. As the air purifier is stationed in my living room, there wasn’t any need to use this mode.

Favorite Mode

In this mode, you select the total coverage area of the room where you plan to place the air purifier. Which means you first need to lớn measure the width(metres) x length(metres). In my opinion this is the best setting khổng lồ choose because the air purifier will operate at a level which is relative lớn the area it’s covering. It should be that way as you wouldn’t want it to lớn be on low setting while trying khổng lồ cover a large area & vice versa.

Available selection of modes.

Usage và Performance – Automation & Scheduling

One great feature I lượt thích about using the app is the ability for creating your own automation task & scheduling. Let’s talk about the automation first. With the automation task, you can create ‘if-then’ statements. Pretty geeky i know. An example of automation you can create; If the air purifier detects the air chất lượng at a certain level, the air purifier will turn on. Another funny one you can create; Trigger the air purifier when receiving a phone Gọi. With scheduling, you can create multiple schedules for the air purifier to lớn operate. Personally I have sầu created a schedule to lớn turn on 15 minutes before I reach home from work.

Usage và Performance – Air Quality

Now many of you can’t wait to lớn find out how’s the air quality lượt thích after using the Air Purifier 2. To phối expectations right, I didn’t have any scientific testing method lượt thích the Clean Air Delivery Rate (CADR). Instead I only relied on the second best thing, my nose. I qualify for that because the area I live sầu in is an industrial area và partly surrounded by factories. In addition, there’re also constant open burnings that result in short periods of haze in the middle of the night.

So based on my sense of smell alone, I’m pleased khổng lồ inform that the Air Purifier 2 works impressively well. There have been numerous occasions where the air outside was filled with either a burning smell or a chemical odour. After turning on the air purifier 2 for about 5-10 minutes, the air in the house was clean, fresh and khổng lồ a degree crisp. This was of most importance not only lớn my health but also to our newborn. Plus the fact that I have a dog và cát, ensuring good air quality in my house was high priority.

Smart Home Integration

Xiaomi has got you covered with Amazon Alexa và Google Assistant integration. And both works like a charm. Just tìm kiếm for ‘Mi Home’ as the service lớn connect lớn when setting it up. I did find that using the Google Assistant was slightly faster by 1 lớn 2 seconds compared khổng lồ Amazon Alexa.


Some may be wondering how loud is the Air Purifier 2. Well, the màn chơi of sound emitted depends on how hard it works. The higher work rate, the louder it gets. Nothing too distracting khổng lồ be honest, và after a while its just like trắng noise.

Final Thoughts

One of the main reasons I got the Xiaomày Air Purifier 2 was for the display of the air chất lượng index. As far as I know, this is the only filter that has this ability. Other brands like Sharp in their mid tier khổng lồ high kết thúc models only give indication whether the air chất lượng is ‘Good’ or ‘Bad’. I’ve sầu been using the Air Purifier 2 for about a month now & I’m very happy with it. The air in my living room remains clean & I’ve sầu not been disturbed by the occasional air pollution in my neighbourhood.

Another point lớn note; As much as it is an air purifier, don’t expect it khổng lồ clear the air from heavy duty cooking that have ingredients like garlic or onions. You need an exhaust người for that. One minor gripe is that I would have hoped for another physical button to lớn adjust the output level. Other than that, the Air Purifier 2 is an elegant sản phẩm that does its job well. Highly recommended if you have sầu a entry level air purifier & are looking to upgrade & also khổng lồ try the Xiaomi brvà.
