Who Would Buy This: Those shopping for a portable, quiet, true HEPA air purifier suitable for large rooms up to 500 square feet.


  • The Whirlpool AP51030K has a Clean Air Delivery rate of 315 which allows it to purify air in rooms as large as 500 sq ft at a rate of 4.8 times per hour, making it suitable for the largest rooms in most homes. Despite its capability, the unit is compactly sized measuring just 20″ x 24″ x 10″ (W x H x D). The built-in handle makes it easy to carry the unit from room to room.
  • This air purifier uses three stages of filtration which consist of a true HEPA filter plus a pre-filter and carbon filter. The pre-filter and carbon filter effectively capture large particles both via the exterior grill before they enter the machine and then inside via the carbon filter. The HEPA filter captures up to 99.97% of airborne particles sized 0.3 microns or larger. Common particles captured are dust mites, pet dander, cigarette smoke and pollen, to prevent allergies and significantly enhance air quality in your room.
  • Whirlpools advanced Quiet Partner® System has been designed for superior sound reduction so you can enjoy whisper quiet air purification without sacrificing high efficiency.
  • Simple electronic controls make operating the Whispure 510 a piece of cake. Four fan speed settings allow you to set the unit from Low, Medium, High or Turbo at the touch of a button. Additionally, there is a sleep mode that automatically sets the unit to a low speed gradually over an 8 hour period. This mode is ideal for use at night when you desire quietness and want to conserve energy.
  • The control panel features two filter replacement indication lights which inform you via a 5-light display when exactly you need to replace the HEPA filter or the charcoal pre-filter.
  • Energy star rated for environmentally friendly efficiency.


  • Replacement filter maintenance costs are rather steep at about $100 a year for the required HEPA filter and pre-filters.
  • The Turbo speed setting makes a quite a loud noise. However, this setting is only needed when high speed air purification is required.
  • The charcoal pre-filter has a limited amount of carbon so it can only capture lighter odors, not the likes of VOCs and strong gases.

Guarantee: 5-year limited warranty plus 30-day money back Quiet guarantee.


Those after a user-friendly, flexible, portable air purifier which is a proven performer for getting cleaner air in large rooms need to look no further than the Whirlpool AP51030K.

This unit excels in capturing particulates which makes it ideal for the removal of dust, smoke, and pollen so it’s suitable for asthma and allergy control. It isn’t so effective at capturing strong odors due to the limitations of its pre-filter, so keep in mind what you want from it before deciding whether it’s right for you.
