A true HEPA filter, carbon filter and pre-filter make up the three stages of filtration that are utilized by the Whirlpool AO51020K. Larger particles are prevented from entering the unit by the grill on the outside that serves as the pre-filter.
Particles that get past the grill are gotten by the carbon filter that eliminates odors and protects the HEPA filter’s life. There are over ninety-nine percent of particles removed by the system as it filters the air riding it of 0.3 micron and larger particles. Ragweed, pollen, dust, danger from pets and other irritants are removed out of the air to improve air quality and relieve asthma and allergy symptoms.

Reviews:
The Whispure Air Filter from Whirlpool has a total of one hundred and eight Amazon reviews that give it a total overall rating of four and a half out of five stars.
The negative review that consumers found to be the most helpful gave the unit a rating of three out of five stars. The reviewer found that the unit did what it claimed when it came to removing particles from the air. The pre-filter only kept pet hair out of the unit but was considered to be useless otherwise. The odors were not eliminated from the air although the HEPA filter itself did an amazing job for the reviewer. The quietness and air volume that went through the unit were a plus to the reviewer and the lights were not too bright on the unit. Eventually the reviewer sent the unit back because it put off too much heat.
The positive review that was found to be most helpful gave the unit a rating of five out of five stars. The reviewer was satisfied with the unit’s overall performance and pointed out that the unit had to be set on the highest level in order to achieve the degree of filtration stated in its specifications.
Other reviewers found that the unit was too loud when placed on high and the foam around the fan on the inside helped with the air flow. The fan hitting the foam made the noise worse. The smoke smell from cigarettes took a few days to remove from the air. The majority of reviewers were pleased with the unit’s ability to clean the air.
The fact that the positive aspects of the Whispure Air Purifier from Whirlpool outnumbered the negative aspects with even those giving negative reviews finding positive aspects means that we can recommend the unit to consumers that are searching for a way to remove dust and other allergens from the air. The unit will give you piece of mind as it improves the quality of the air and eases your ability to breath.
