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.
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.
Use this all the time
This is the second Whispure air purifier I've purchased; the first one was the less expensive model, and both have been fantastic. They also take the same size filters which is very convenient.
This one is quieter and less boxy-looking than the cheaper model.
Loud, initially worked well but after 2 3/4 years quality decreased. 3 years I am replacing the entire unit due to the fact that it no longer removes the dust in the air despite changing the filters more than recommended. Dont wasted your money like I did.
I have researched many air purifiers and without going above $500 this is definitely one of the best ones. I own 3.
Whisper quiet . Great airflow.
Different options. Super turbo which is noisy but strong. Lowest setting is quiet. I vacant really feel a difference.
I bought this for my bedroom and didn't look at the dimensions. This is huge. It does a good job of cleaning the air but it isn't particularly quiet. That's not really a problem for me because I run a fan for air circulation all the time but if you want really quiet look elsewhere. Also this is too big for my bedroom so I'm going to move it out to my great room and get something smaller for in here. I'm not thrilled about the cost of the replacement filter which according to the book will last a year give or take. Living in LA as I do it will be the take side by just how much is what I'll have to see. I am replacing 2 Hunter purifiers that did their job admirably for many years but nothing lasts forever. I liked them because they had a washable HEPA filter. You can buy charcoal filters (prefilters) really cheap by the roll and cut them to the size you need. Don't get fooled into spending a lot more on buying a 'brand' name. They're all the same.
