Final thoughts on Whirlpool AP51030K

We strongly recommend the Whirlpool Whispure AP51030K air purifier for someone associated with allergen or bacteria allergies. Comes with a 5 years warranty, it is capable of providing silent filtration throughout the whole process, a wide coverage area, neat electronic control buttons, convenience features such as internal cord storage system and filter replacement indicator. The only thing that I would dislike is probably the outdated aesthetics look which I guess it shouldn’t be a problem for most people.

In conclusion......

  • Wide purifying coverage area.
  • True HEPA-filter.
  • Silent operation throughout sleep mode to turbo mode.
  • Built-in cord storage system.
  • Separate filter change indicators for both pre-filter and HEPA-filter.
  • 5 years manufacture warranty.
  • Charcoal pre-filter not strong enough to deal with heavy odors and gases including certain notorious VOCs.
