It works very well in automatic mode. Just in automatic mode, it doesn't go into night mode. It doesn't have a light sensor, in short, like its bigger siblings. Anyway, Winix guarantee.

I have it since yesterday. It worked for a few hours in a room of about 15 square meters with closed windows. It doesn't clean odors, I didn't feel a difference in air quality, but I could breathe freely, I have allergies to dust and my nose is almost always stuffy. So it works, but it would be nice if it also collected odors.

I expected it to be a little quieter. I have had the Zero for 2 years now. It is reliable and has significant indoor air purification and odor elimination. It would be ideal if it were a little cheaper, a little quieter, and had cheaper replacement filters.

I have purchased it twice, initially for professional and then for personal use. It is extremely quiet and it seems to clean the air very well. With Covid at home, without paying attention, the other members did not get infected. The same happened with type A flu. Plus, it is very elegant.

I mainly have it in my bedroom and I have noticed a significant difference when I have it open in the room. Initially, I stopped sneezing constantly, and I feel that the air is cleaner in terms of odors. The only negative is that if you have it on for many hours, it makes the room dry, but this also applies to dehumidifiers, so I use it for specific hours. It's worth its money, even though I bought it with a gift voucher redemption of 80 euros and got it for 70 euros instead of 150

Used for a 55m² room for 2 years. You can really feel the air being cleaner and it creates a gentle breeze when you stand close to it. It is not bulky and takes up minimal space.
Simple sturdy construction with hard plastics and a touch screen on the top. There is no air quality display, only 3 color indicators: blue for clean, orange for moderate, and red for bad air.
For air flow, it has manual operation with 3 levels or automatic. In automatic mode, it responds immediately when it detects smoke or particles. It makes a loud noise when running at full power. It also has a night mode.
It has a plasma function which you can deactivate, I don't know if it is effective or even measurable.
To access the filter, you unscrew the white frame at the bottom. The filter is not for odors and don't expect it to collect floating dust particles.

I bought it for Christmas for the children's room (13.5 m2). The goal, besides what is mentioned, was to have a sense of clean air in the room and especially to eliminate any odors, mainly those from fireplaces during the night hours (Athens area). The room is generally well-ventilated (high ceiling) and airy.
Regarding the functions, everything seems to be working correctly as stated by the manufacturer. However, there is no sense of clean atmosphere whatsoever, and most importantly, it is NOT effective at all in eliminating odors.
I have had an old good Philips Naturis 100 for many years (23 years), and I can say that it is clearly more effective compared to the Winix Zero Compact.

For anyone who has a pet and faces allergy problems, this device will be their magical solution. Only when this is present in the space, I don't get congested from the allergens in the atmosphere.

I paid 200 € for a smaller cleaner due to lack of space, but I made a mistake. It's not worth it, better to get the larger one. I didn't feel any difference in my space, and I live in an area where air pollution is 350% above the limits for PM2.5 and PM10 particles. It's a relatively nice small device, but construction-wise, it's overly simple for its price

I have it in my kitchen 55 square meters and I am satisfied with its performance, very good construction and with a top filter that will be on the market for years. Also, the plasma wave technology is the icing on the cake. At 150 euros, I don't think you will find anything better with so many certifications
