Whirlpool Whispure is a great air purifier for those suffering from respiratory problems or allergies, as it removes pet dander, pollen and dust mites from the air. If you are looking for a large purifier, the Whispure AP51030K might be the best choice, due to its incredible cleaning capabilities without releasing ozone into the air.


The Whirlpool Whispure AP51030K gets top scores in tests, exceeding expectations for filtering cigarette smoke, pollen, and dust on either high or low speed. The air purifier significantly reduces the particles in the room, even in large spaces where you might think it would fail because of its petite size. This model is great for eliminating asthma and allergy symptoms as it captures dust particles in the room. However, the filters are not equipped to remove airborne pathogens. At its highest setting, the purifier has an airflow of 347 cubic feet per minute, much higher than many large room air filters. The Whirlpool Whispure is great for people with breathing-related problems. Although this air purifier is Energy Star qualified and has an affordable initial price, the replacement filters cost about $100 per year.

Design and Ease of Use

This air purifier has a modern, simple design that can blend in any room. The machine is easy to use, as it has a nicely-labeled dashboard and electronic controls. A convenient five-stage filter status indicator lets users know when it is time to replace the filter. According to most user reviews, the controls are easy to use and the various options for spin speed are very useful, as it aids in noise control. Furthermore, it is quieter than similar air purifiers on both low and high setting. It is one of the quietest portable air conditioners we tested. Therefore, you will have no problem watching TV at normal volume levels even if it is sitting next to you. When you are not in the room you can ratchet it up to the turbo mode and lower it when you return.

Other Features

While most air purifiers available on the market use UV lights and ionizers to sanitize the air, the Whirlpool Whispure AP51030K relies only on its filters. If you have breathing-related problems, this ozone-free model is an excellent choice. Although it has great safety features, this model lacks some convenient features such as a remote control and an air-quality sensor. However, there is a filter monitor and a sleep mode most users will find very useful. After you get used to the air purifier, the missing features will become a non-issue, although we would have liked to see it offer more flexibility. There are also 4 fan speeds, including a turbo setting and electronic controls. Its True HEPA filter removes 99.97% of particles, including dust, tobacco smoke, pet dander, pollen, mold spores and fabric fibers. This model is AHAM Certified CADR.
