I'm pleasantly surprised how well this performs. I can quickly tell the difference in air quality in just a short amount of time. It's made a big difference to the air quality in my home.
We are enjoying the purifier but are trying to change the filter. We have ordered several and they are all the wrong size. There is no number to help us. Any advice???
What I like about it:
1) It's aesthetically pleasing (i.e. it looks nice).
2) It's simple, easy, and straightforward to operate.
3) PM2.5 light indicates the quality (or lack thereof) of the air. Green is best, Blue is good and Red is the worst.
4) Even better than the light indicators referenced above, a panel display indicates the PM2.5 index. PM2.5 stands for Particulate Matter that is 2.5 microns (or less) in size. It is a measure of the quality of the air. A lower number indicates a better quality, while a higher number indicates poorer air quality. A sensor of the machine measures these particles in the air near the vicinity of the machine. So, for example, a reading of 5 would indicate there are 5 micrograms of particles 2.5 microns or less in size per cubic meter of air. The PM2.5 index gives you a more specific indication of the air quality -- whereas the colored panel lights give you a general, relative range.
For example, on my machine, a green light indicates air containing anywhere from 0 to 15 micrograms of 2.5-micron particles per cubic meter of air. But the PM2.5 index display tells you exactly where you are in that range -- for example 5 or 13 micrograms per cubic meter of air.
5) Machine has a timer. 5 time periods for 1/2/4/8/12h or always running.
6) It has 4 working modes that will meet different needs. So you can also sleep in an ultra-quiet and soothing indoor environment.
Overall, I would recommend this air purifier. It's easy to use, it performed well.
It is very portable and I can take it with me anytime. Because my skin is prone to dryness, I need a humidifier that is easy to carry around to replenish the skin's moisture at any time.
