Review: Arrived in perfect condition - It's exactly what it describes. The purifier draws in air from below and expels clean air from above. Even He even warned me that when I left a pot on, the purifier would mark the air as unhealthy.
Review: Surprisingly quiet. - This Xiaomi Smart Air Purifier 4 Compact has surprised me in a few ways. First is the price. I haven't seen another major brand air purifier as reasonably priced as this unit. Second is how quiet it is. I have always rejected the idea of an air cleaner/purifier because of the noise. Well, this has NO noise, seriously in automatic mode, this unit is quieter than the quietest whisper. I am one of those people who needs complete quiet and darkness to sleep. This unit, well, you can't even hear it until you put your head by it when it's in automatic mode. And the touch screen can be completely turned off (no light!). I had an issue with a dead thing in a part of my attic that could not be reached, which the exterminator guy said was most likely the reason it couldn't escape and expired. Well, air purifier to the rescue. In a few hours' time, the odor was gone. I felt that the air was then clean of whatever bacteria was floating around with the odor. This is easy to use. It immediately paired with my home wi-fi. There aren't many instructions, because it is so easy to use. It's nice looking, not a utilitarian vibe. It is really sturdy and heavier than it looks, which for me, shows the quality of the build. I don't have experience with air purifiers, so I don't know how this compares in size with others, but it's sturdily made. Feels like good quality and being from Xiaomi, I'm sure it will last for many years. I can highly recommend this to everyone.

### ⭐⭐⭐⭐⭐ Easy to Use 360° Air Filtration
*by R***K on September 7, 2025*

Air purifiers come in assorted sizes and shapes. This compact model features an ample filtration surface, an automatic sensor, and a sleep mode. About 14 inches tall, the purifier is well suited for dresser or countertop locations. An approximate footprint of just over 8⅝ inches facilitates placing it on surfaces that have minimal space available. The primary requirement is to have sufficient space on all sides for the 360° filtration to work. The accompanying instruction manual recommends at least 8 inches of unobstructed area. I use mine in the living room on a sofa table with 12 inches of open area in the back and completely clear on all other sides. With the purifier having a small footprint on the table, there is plenty of room for other items. The intuitively designed controls on the top of the purifier are easy to use. Pressing the controls is not necessary since they function via a capacitive touch system that responds to a light finger movement. Cycling through the fan modes is simple. The manual mode, signified by the “heart” shaped symbol, adjusts via a downloadable app, sleep mode is a low speed, and auto mode selects fan speed based on air quality. There is a “particle sensor” at the rear of the unit to determine air quality. Included with the purifier is a three-stage HEPA filter. The outer pre-filter captures larger airborne particles, the second stage provides HEPA filtration, and the inner activated carbon filter removes odors, smoke, and fumes. I use this purifier in the living room, and it seems to perform well there, but I have not tested it in a location like a kitchen where smoke or cooking odors would be more of an issue. I do have another purifier with a similar filtration system in the kitchen that works well for those purposes. The filter in this purifier is small. Around 6¾ inches tall, it occupies a bit under half the purifier interior space. A filter replacement indicator on the top should light up as a reminder to replace the filter. Final Thoughts: Compact and portable, this purifier is easy to set up in one room or move from room to room as needed. Although this is a small HEPA filter, the fact that it allows 360° airflow increases the filtration surface area. Placing it in a location that allows air intake on all sides will maximize its effectiveness. I don’t like to download many apps to control devices and did not do so with this filter. The additional functionality provided by the app may enhance manual mode operation, but I prefer to let the purifier operate in auto mode. My specific use for this purifier is living room air filtration. It seems to perform well in that setting and should work equally as well in a living room or an office. If I were using it in a kitchen to remove cooking odors, I would probably place it close to the area that requires air purification. Overall, this is a nice, compact air purifier that is both functional and simple to use.
