The Whirpool Whispure A510 is the BEST Air Cleaner!
We have owned two Whispure AP510's for over five years now. Both units have run practically 24/7 at the TURBO setting, and are still operating beautifully. Over the years, prior to buying our Whispures, we have had Sharper Image tower air cleaners, a Honeywell whole house electronic air cleaner on the furnace, and the comparable Honeywell Envirocaire air cleaners. These two Whispure's have them all beat. We used the Envirocaire in a different, smaller home, and replaced it with a new one when the motor burned out at approx. three year's continuous use. Both Envirocaire's made progressively more noise with age, to the point of being completely unacceptable even with impeccable maintenance. In my opinion, Whirlpool's Whispure design is preferable over the Envirocaire because (1) you can place the unit unobtrusively against a wall or in an unobstructed corner and (2) cleaned air vents out the top of the unit instead of the very noticeable floor draft produced by the Envirocaire (that can be significantly uncomfortable in the winter months), and (3) there are five different air speeds: Low, Medium, High, Turbo and Sleep Mode vs three fan speeds on the Envirocaire. I like the reminder lights on the control panel that keep track of your filter changes and/or your need to replace the carbon or HEPA filter. (The control panel also features a "Control Lock" function to prevent curious little ones from changing your settings by irresistably pressing the "buttons" on the touch panel.) The HEPA filter easily lasts a year with the minimum recommended carbon filter replacement. Maintenance is a breeze: The front cover comes off in one single motion-just grasp the cover at the easily located tabs high on each side and depress gently, the cover lifts right off. The tab-lock mechanism is so well made, it should never break. The carbon pre-filter has slots cut into the fabric that fit onto matching tabs on the inside of the front cover. The slots/tabs design situates the pre-filter exactly where it needs to be to fully cover the HEPA filter and holds it in place while you snap the cover back in place. The HEPA filter is sturdily made with an approx. 1" Wide plastic frame as integral part of the filter. The side facing the rear of the air cleaner has an applied seal that ensures incoming air passes through the HEPA filter and not around it. Our Whispure's were not only worth every penny we paid for them, the pre-filters (4 per pack) and once a year HEPA replacement (at maximum), is every bit worth their cost when you get such a high level of quality. Both of our Whispure's are almost as quiet as the day we bought them (over five years ago, running on TURBO 24/7) and still provide a high CADR (clean air delivery rate). (Note: Allergies, pets and used during use of oxygen concentrator.) In my opinion, this is the best portable home air cleaner.

Display stopped working
The display no longer works and Whirlpool gave me a major runaround over the phone even though their warranty is supposedly still in effect. The unit is less than a year old.
