I like it. I set it up as per instructions and it works just fine as expected.
I am a thorough and thoughtful shopper, comparing features, design and pricing. I finally decided on this unit and am very glad I did because it appears to be a quality product. It is quiet and yet it moves a large volume of air. The HEPA filter is large and thick with several layers. It takes air in through the large front area and disperses clean air through the top of unit. The warranty inside the user manual states it is a 4 year warranty and if you register within 30 days they will include an extra year and that makes it a 5 year warranty. I really feel that this is the best deal so I am buying a second unit today.
I love the modern styling, most especially the timer feature and that there is just one easy step for filter installation and replacement. The unit is quiet when turned on.
It's really a nice unit (and it looks good too). It's so quiet it is ideal for a bedroom. Speaking of that, when you select "sleep-mode" all the indicator lights go out except for one and it only emits a soft glow. Changing the filter is a snap the pre-filters are bundled with the HEPA filter. There's no mess to clean-up afterward. I really enjoy this HEPA Air Purifier.
