Whirlpool Air Cleaners - How do they work?

The Whispure from Whirlpool uses a True HEPA Filter to capture 99.97% of airborne particles as small as 0.3 microns from being released back out into your room. Just how small is that? 1,100,000,000 would fit in an area smaller than one square inch.

Whispure is one of the quietest high efficiency True HEPA purifiers you can buy. It works night and day to constantly circulate the air through its True HEPA Filter, releasing only pure clean air back into your room.
Whirlpool Whispure air purifiers give top quality performance - efficiently and quietly.

Whirlpool Whispure air purifiers combine an advanced airflow design and the True HEPA Technology to provide whispure quiet operation. In fact, Whirlpool guarantees that you will not find a quieter high efficiency air purifier- anywhere, or Whirlpool will buy your unit back.

Whirlpool Whispure air purifiers use TRUE HEPA Filtration technology to remove harmful particulate from the indoor air you breathe every day.

The Whispure Air Purifier uses a two filter system to clean the air. The deodorizing charcoal pre-filter should be changed every 3 months, while the True HEPA Filter should be changed once every 12 months depending on use.

How do you know when it's time to change filters?

The Whirlpool Whispure is a high performance air purifier, meeting or exceeding the industry standards.

What is HEPA?
HEPA stands for High Efficiency Particulate Air. In order to earn a HEPA rating, an air purifier must collect air particles as small as 0.3 microns. Exactly how small is that? 1,100,000,000 would fit in an area less than a square inch. But that's no problem for the Whispure? Air Purifier. It uses a True HEPA Filter to capture 99.97% of airborne particles as small as 0.3 microns from air passing through the filter, preventing them from being returned to your breathing environment.

What is CADR?
CADR is the Clean Air Delivery Rate, or the amount of clean air that an air purifier can deliver to a room. When choosing an air purifier for a specific room size, remember a higher CADR is better. If someone in your family is more sensitive to airborne particles, select a higher CADR rating than your actual room size.

Place your Whirlpool Whispure unit anywhere in the room, even against a wall!

Whispure air purifiers have a front to top air flow, letting you place the unit anywhere in the room for the same quiet efficient operation. On some models, you can control it's operation with electronic controls while on others you will have rotary controls. Either way, your Whirlpool Whispure will be working hard to keep the air in your home or office healthy and clean.
