It's important to replace the pre-filter in your Whirlpool Whispure Air Purifier
every 2 to 3 months to protect and prolong the life of the HEPA filter
. The pre-filter captures larger airborne particles and also helps to freshen air by reducing gases and odors.
Pre-Filters available in:
- Medium-size Pre-Filter fits the Whispure AP250 or previous AP150 air purifier models
- Large-size Pre-Filter fits the Whispure AP450 and AP510 models
4 filters per box.
This 4-pack box contains about a year’s supply of pre-filters, assuming regular replacement every 3 months. In environments with heavier airborne particles or odors, such as homes with pets or smokers, it is likely that you will need to replace the pre-filter more frequently.
Protect the life of your HEPA filter with recommended replacement of the pre-filter every 2-3 months. Be sure to select the appropriate pre-filter for your Whispure Air Purifier and replace it regularly to keep the air purifier performing at its best.
