Review on Holmes Small White True HEPA Air Purifier by Danish Affndy ᠌

If you know why you need it, then this cleaner is your choice. In Hong Kong, peat bogs are burning in 2022-2022, smog is very common on the street, the PM2.5 level is from 50 to 300. If you close the windows, then, due to their small size, dust particles of this size settle only after 4-6 hours, most of them settle in your lungs. So, at the maximum level, this purifier in 15 minutes in a closed room of 16 squares reduces the level from 50-100 to 5. At night it maintains 0-3, at a time when it is more than 100 outside. this particle size is not a hindrance. That is, you can "ventilate" with smog, and in 15 minutes there will be clean air at home. At home there is a Qingping Air Monitor Lite dust detector, it confirms that the air is being cleaned in all corners of the room, and not just above the purifier (it mixes the air very much). Immediately after the purchase, I made additional filter protection with a HEPA cloth from AliExpress, and also set up automation not using my own PM2.5 sensor, but using an external Qingping Air Monitor Lite. Because, it is logical that your own shows the air cleaner due to the proximity of the filter. In general, for those who are in the subject - a must have!
