Whirlpool was founded over one hundred years ago, on the eleventh day, of the eleventh month, 1911. Since then, they’ve undergone several name-changes, acquired other companies, and learned quite a few lessons. This kind of experience cannot be replaced or faked, and it shows through whirlpool’s products, just how long this brand has been in the game. Today we’re going to be reviewing the Whirlpool Whispure AP51030K air purifier, to see how it measures up to its brands titanic reputation.

Whirlpool Whispure AP51030K

Retailing for about $245.71, the Whirlpool Whispure AP51030K falls roughly into the middle-range of the market, price-wise. With excellent specifications, this unit can perform its duties effectively, however, it does lack a few convenience enhancing functions and features that we would have liked to have seen integrated into the final design. Read our full review below for more information.


Cleaning Capabilities

With possibly the highest Clean Air Delivery Rate (CADR) scores of all of the Purifiers we have reviewed on this site, the Whirlpool Whispure AP51030K is capable of cleaning rooms as large as up to 490 square feet. Providing nearly five air exchanges an hour, all of the air of the room will pass through this device approximately every 12 minutes or so. This means that the Whirlpool Whispure AP51030K will regularly pull pollutants from the air. For this reason, we would recommend this unit for individuals suffering from allergies.

The Whirlpool Whispure AP51030K functions on a 3-stage filtration system, beginning with a pre-filter that removes large particles from the air such as dust, hair, and pet dander. Following this, is a carbon filter which is engineered to remove odours from the air. Finally, the air is passed through a built-in HEPA filter, which is designed to capture even the smallest pollutant particulates.

This system is exceptionally effective, removing 99.97% of airborne pollutants down to 0.3 microns.

See below for this unit’s specific CADR scorings across a range of criteria:

  • Smoke: 316
  • Dust: 325
  • Pollen: 401


Efficiency / Certifications

Pulling 102 watts, the Whirlpool Whispure AP51030K may not be the most energy efficient air purifier we have reviewed, however it is Energy Star certified, which declares that this unit adheres to a set of energy consumption related regulations set out by the Environmental Protection Agency.

Thankfully, the Whirlpool Whispure AP51030K benefits from several other certifications that we commonly look for. These include the AHAM and ARB certifications, and the UL-Listed mark of approval. The AHAM certification indicates that this device received its high CADR scores by following AHAM’s industry-respected testing procedures.

Being ARB certified guarantees that this unit will not damage air quality, while being UL-Listed declares that this unit has been deemed safe for public use by Underwriters Laboratories.

Efficient operation is further encouraged by the inclusion of 6 speed settings in total, consisting of four fan speeds, a sleep mode, and a turbo mode. This allows the user to draw the performance they need from their unit, no more, no less.

It is considered highly admirable for a unit to benefit from this many certifications, not to mention the presence of such certifications allows the user peace-of-mind in that they can rely on their unit to function properly.



The Whirlpool Whispure AP51030K boasts some of the features that we would usually look for, however lacks others. With a 24-hour programmable timer, the user is enabled to program times of operation into their device. This is especially useful if you require your unit to operate while you are away from home.

Further, as mentioned above this unit also avails of a Sleep Mode, a personal favourite feature of ours. This essentially means that the device will not interrupt your sleep at night, functioning at a decreased capacity, therefore making less noise, and saving energy. A turbo mode is also included for heavy operation, should it be required.

However, unfortunately the Whirlpool Whispure AP51030K lacks a remote control, or an auto setting. These features, the wireless remote control in particular, are basic enough that we expect them in nits of this cost.



Weighing 20lbs this unit is certainly one of the heavier air purifiers we have reviewed, however, it is relatively small, and therefore, finding a place for this unit in your home should not prove difficult. With a noise level of 55dB on its highest setting, the Whirlpool Whispure AP51030K is impressively quiet. For reference, the average human conversation usually registers at about 60dB, with a whisper usually registering at approximately 30dB.

The user interface on this product is relatively easy to understand, with a simple display at the top of the front face, over the vent. This interface consists of five buttons, clearly displayed, making the product quite user-friendly.


Help & Support

The Whirlpool Whispure AP51030K is backed by Whirlpool’s impressive five-year limited warranty. This warranty is the largest in the industry, and is something Whirpool should definitely be commended for. For more information regarding Whirlpool’s warranty policies, we recommend that you contact Whirlpool directly.

With regard to customer support services, Whirpool representatives are available via email and telephone. Should you lose your user manual, there are also downloadable user manuals available on the company website, although unfortunately there is not an FAQ’s section provided to solve any small issues you might be having with your device.



Whirlpool certainly deserves praise for the Whirlpool Whispure AP51030K. It’s clear that their teams put effort into the design of this product. With an industry-leading warranty, and possibly the highest CADR scores we have come across at Air Conditioners Rated, this product is certainly one to consider for anyone out there suffering with allergies. Our only issues with this unit are its lack of convenient features, and the lack of an FAQs section online to provide support for the user. However, both of these issues can be forgiven to an extent when the Whirlpool Whispure AP51030K’s strengths are considered.
