I was basically the HEPA filter in the unit important because I mainly a problem have dust mites. So Fellowes ordered, unpacked, plugged. The device works as it should, 4 steps and an auto mode. However, I am not really satisfied.
*** The included HEPA filter has an indentation in the vertical direction, which means that my activated carbon filter does not fit correctly and bulges outward. Fail. But I'm not quite sure if that would not have happened without the dent. Also, I would have hoped that the HEPA filter (such as on my vacuum cleaner) has a rubberized statements and then somehow be harnessed so that the system is tight and the air are actually 100% is drawn through the filter.
Now I have just everything moored with tape.
*** The rotor blade on the drive shaft wobbles. In addition, the fan does not run constantly at the same speed. This varies rather sinusoid shaped every two seconds. Have first thought of fluctuations in the power grid, but this through a test run in a different house (hopefully) be excluded. Second thought: The internal power supply normally makes a corresponding circuit (capacitors, etc.) for compensation and a uniform current flow to the motor. That leaves the assumption that the circuit was in the unit rather poorly designed (to do so often times, because each saved component saves money). "Yeah, well, pretty picky this type": Now think of the reader. However, the fan runs with me 24/7 and when one is sometimes in bed, everything is really quiet and the Fellowes on low / medium simulates the swell on the Titanic, then the quite annoying. Will ye that I get seasick?
* The PlasmaTrue technology can not be disabled. Moreover, it could have just passed a green LED, this flashing ion nervous. At this point, a suggestion: night mode, the display panel.
* The life indicator measures so now not the degree of contamination of the filter, but is simply a timer. For these bells and whistles, the basic components would manstatt which can add value.
* The purity sensor is noticed as Garnier, seemingly not a particle. But since I know my not so. Only you have to stop to remember that you need for the car mode an objective air quality measurement in order to control this properly. An air filter is indeed bought primarily not because of bad smell.
All in all the things that you can ignore, but I paid just 200+ euros for this device, and at such a high price, you might wish to consider to make some things better. I have here but rather the feeling that something has been developed to serve a niche to leave no empty field to the competition. Fail # 2
