Review: I have asthma and have this unit monitoring air quality in my living space 24/7 (connected to wall outlet via usb port adapter). Particles count seems to be accurate since it agrees with my air max 320 HEPA filter. VOCs sensor sensitive to any strong smell (food, paint, dish soap, etc). In order for unit to be accurate you need to leave it where you need to measure for at least an hour or so. Compared to other units on the market this is probably the best bang for the buck for instant readings. I also have an air wave sensor but that one seems to be better for longer term averages than instant readings. Battery life on unit is very short so I just keep it plugged in. Does not feel cheap, appears well built but user interface could use a refresh or update.
Review: Es un excelente equipo. Lo único es que es muy pequeño por la pantalla que despliega los datos y las mediciones. El manual explica de manera muy oportuna y comprensible. Me hubiera gustado que viniera en un estuche para evitar riesgos de uso.
