I live in the California dust bowl. Yes, Bakersfield. Indoor air quality is dependent on what YOU make of it because opening a window for fresh air is out of the question. I bought this on a recommendation from a health provider. After evaluating ALL the pros and cons, this was my choice because of OVERALL use, effectiveness, maintenance. The filters are both permanent and washable . Static is stored in the filter and you will discharge it by touching. Does not hurt, but surprising. This product works. The air is lighter, you can feel stuffiness being removed on the first day. It is quiet. The unit is aesthetically well built. Even the ambient light has a pleasant glow to it has two settings of brightness. The air being given off is strong to even be "cooling" in the summer. If you are a germ-a-phobe , get one with UV. If you want a great air purifier that cleans the air including germs with no filters to buy, THIS IS YOUR UNIT.
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.
Hands down it is a good product, well built and designed. My issue is that the ionizer is always on and creates a very very distinct smell. I wish that this feature could be turned off. I would say purchase it if you are okay with the ionizer type smell but avoid it if it irritates you.
The product does a great job of reducing my place of allergens and reduced dust build up I've noticed.
