Whirlpool Whispure AP51030K Air PurifierWith a three-stage filtration system the Whirlpool Whispure AP51030K really packs a punch. In a large 500 sq ft room this air purifier will filter the entire room almost 5 times per hour. Three components help to achieve the best air quality, a pre-filter, a carbon filter for large particles and a true HEPA filter that will remove over 99.97% of particles in the air that are over 0.3 microns.

The carbon filter also helps to remove odors form the air and protect larger particles from damaging the HEPA filter. Whether it’s mites, mold spores, dust or pet dander your air will be clean and free of the particles that may irritate your allergies or cause asthma.

Whirlpool manufactures and markets home appliances including fridges, freezers, cooktops, rangehoods, dishwashers and of course air purifiers.The company was founded in 1911 by Frederick and Louis Upton. Headquartered in Michigan, the company aims to continually produce innovative appliances and to keep a step ahead of the competition.

Controls Are Simple To Use

The front control panel gives you easy options for quickly powering on the air filter and changing the fan speed. Pick from low, medium, high, turbo and sleep modes. You can also easily see the filter status for the various filters. The controls are quite simple and there’s really nothing more to worry about except turning it on and choosing your fan speed.

“The controls are simple to use. I find there to be plenty of options for fan speed (noise control). On the lowest setting I can watch TV at normal volume levels with the unit sitting three feet from me. After leaving the room it’s easy to ratchet it up to the TURBO mode which I leave it on most of the time when not using the living areas. I appreciate the indicators which tell you when the filter needs replacing, and roughly where it is at in terms of its lifespan… more

Quiet Air Filter

The Whirlpool Whispure operates quietly and comes with four fan speeds. If you’re sitting nearby you can reduce the speed for quieter operation and when your not at home turn it full blast to clean the air as quickly as possible. The unit doesn’t even make much of a noise apart from the sound of rushing air which can’t be helped. It’s a white noise that should help you to sleep.

Use this in my babies bedroom and it circulates air really well. It’s powerful with a relaxing sound that helps her go to sleep! It isn’t even noisy just the sound of rushing air… more

Fresher, Cleaner Air

Having good air quality indoors is of paramount importance. This is due to the fact that most people spend over 90% of their time indoors and indoor air quality is between 2 to 5 times more polluted then outdoor air. With the Whispure you’ll notice the air is immediately fresher, making living indoors much more comfortable.

After 2.5 months of use I find that there is a noticeable difference in the quality of the air. It feels fresher, smells cleaner, and I can’t see dust flying through the air. I don’t have allergies, but feel that the investment is well worth the reduced dusting, potential health benefits, and… more

Affordable Price

This Whisper air purifier is pretty good on price considering it operates with a true HEPA filter. Many cheaper models will only filter out particles no smaller than 3 microns. The AP51030K will filter out anything bigger then 0.3 microns and the difference is astounding as dust and bacteria will get caught in the filter, reducing the potential for allergies and sickness. As far as price vs quality goes this is one of the most affordable.

So is it worth it? Absolutely. As of today, the best all-around filtration is a true HEPA…and you need a sizable filter and a sizable motor. Therefore, any good filter will have a larger form-factor. The AP51030K is pure performance and while it is by no means cheap, its performance outclasses many filters that cost significantly more. For the home user, it is arguably the best choice on the market in terms of cost versus performance… more


It doesn’t matter how good the air purifier is if it doesn’t work, or work for long. This air purifier is made from top quality materials and should last for at least a few years. Depending on where you purchase you may be able to buy the unit with a 3 or 5 year warranty. An extended warranty is probably not necessary though as the purifier seems to be quite durable.

After nearly 3 years both of my units are still going strong. After many button presses the plastic on the control panel of the unit has bubbled up in certain places. I still highly recommend this product and would purchase again for my self… more

Pros & Cons

Pros – It’s quiet, effective and lightweight. It will do a good job of clearing the air of dust and pollen making your home allergy free. Easy to replace carbon and HEPA filters with indicators letting you know when they need to be changed.

Cons – The HEPA filter can be fairly expensive and you may need to order online. At the highest setting the purifier is quite loud and has a fan like effect on the room, although some people consider this a plus.

What Others Are Saying

First, this purifier seems to work. Before the air purifier, my boyfriend had to use his asthma inhaler 5 times in one night. The purifier arrived yesterday. Last night, after running the purifier for less than 12 hours, my boyfriend did not have to use his inhaler once, and he could tell the difference between the room with the purifier and the room without it.

Second, it’s not loud. My hearing is so sensitive that I rarely turn on my heat and I can’t sleep with my heat on. By contrast, the air purifier is softer than a box fan, way quieter than my heating or air conditioning, and I can easily sleep with it on the high setting.

Third… more


I did my research before buying an air purifier, and this had the most recommendations, so I gave it a try. I’ve had it for over a year now, and use it every single day. The definition of a five-star product so far: has never… more
