The motor in this air purifier turns on a ball bearing, this is a lot better than a standard fan motor, which turns on a lubricated hub. The electrostatic collecting filter is not made out of aluminum, which is what I had suspected, but it is made out of plastic, making it completely washable. I did not even know that plastic could be statically charged. The buttons on the top of the unit are all touch style buttons, except the power button, which is a press button. The bottom of the fan has an illuminated LED light strip which can be turned off. The fan motor has 5 speeds, of which the motor is stable on all 5 speeds, it does not start to make creeking noises on any of the higher levels. This air purifier is more efficient than a Hepa style of air purifier, that is because air freely flows through the electrostatically charged collecting grid, compared to a Hepa air purifier, in which air is forcefully pulled through a Hepa filter, requiring more power to operate.
