Installing or Replacing the 3-in-1 HEPA Filters

This Honeywell HEPA Professional Series™ Air Purifier takes two 3-in-1 HEPA Filters (HRF-Z2). Please see below for the replacement filters for this product. Follow these simple steps to replace your Z filters:

  1. New filters are wrapped to ensure purity, and are labeled to help identify the proper replacement filter. Before using your new air purifier, you must remove the wrappers covering the filters.
  2. Make sure the air purifier is OFF and unplugged.
  3. Open the rear door to remove the filters . Remove the HEPA Filters from the two sides of the unit.
  4. Remove the filters from the plastic bags.
  5. Install the filters into the unit with the red pull tabs facing outward (this will facilitate filter removal later). The side of the filter with the carbon
    granules (black side) and foam seal should be facing in to the purifier housing.
  6. Close the rear door and plug the unit into an outlet. You are now ready to use your new Honeywell Professional Series™ True HEPA Air Purifier.

The Z Filter Replacement Pack includes 2 filters. This is a 1 year supply.

NOTE: the 3-in-1 HEPA Z Filters are not washable. DO NOT immerse them in water.


When to Change the Filter

Most Honeywell Air Purifiers have a “Filter Check/Reset” indicator that alerts you when it is time to change the filter. For the Bluetooth® Smart HEPA air purifiers, you can set your mobile device to receive a reminder when it's almost time to change the filter.

As a general rule:
Pre-filters should be replaced every 3 months.
HEPA filters should be changed every 12 months.

Note: These replacement intervals are intended as guidelines only. Performance of any filter media is dependent upon the concentration of contaminants going through the system. High concentrations of contaminants such as dust, pet dander, and smoke will reduce the useful performance of the filters.


How to Reset the Filter Light

This Honeywell Professional Series™ Air Purifier has two electronic filter checks to remind you when it is time to replace the 3-in-1 HEPA Filters and vacuum or wash the Permanent Mesh Pre-Filters, based on the air purifier’s hours of use. When it is time to replace or clean the filters, one of the indicator lights will illuminate to identify which filter needs to be cleaned or replaced at that time.

When the “FILTER” light is illuminated, you should replace the 3-in-1 HEPA Z Filters. Please note this Honeywell Professional Series™ Air Purifier requires two 3-in-1 HEPA Filter Z Filters. It is recommended the 3-in-1 HEPA Z Filters be replaced every 12 months.

  1. After the HEPA filters have been replaced and/or the pre-filters cleaned and re-installed in the unit, plug the unit into the power outlet.
  2. TAP the Power icon.
  3. Press and hold the reset icon next to the illuminated filter indicator for 2-3 seconds. A chime will sound and the indicator light will flash for 3 seconds and then shut off to show the timer has been reset.
  4. Repeat step if the other Check Filter Indicator is illuminated.

How to Clean the Washable Pre-Filters

The Permanent Mesh Pre-Filters trap and capture larger airborne particles that enter the intake grilles. It is important to keep these clean to optimize airflow into the purifier and trap the larger debris before it reaches the HEPA Filters. These pre-filters can be periodically removed and shaken or vacuumed clean. Alternatively, they can be rinsed by hand under warm water to clean. Let the pre-filters air dry completely before inserting them back in to the air purifier. The pre-filters should be cleaned every 3 months.

To access the Permanent Mesh Pre-Filters:

  1. First remove the two HEPA Filters.
  2. Power OFF and unplug the air purifier.
  3. The Permanent Mesh Pre-Filters are located on each side of the air purifier at the air intake. Grasp the plastic tab(s) for removal and gently pull inward and out of the unit clearing the metal retention tabs.
  4. To replace clean (and dry) pre-filters, simply return them to the same location and set them in place by securing them behind the metal retention tabs.
  5. You will need to reset the eletronic filter check light now.


Can I replace the VOC filters or HEPA filters independently?

No, the 3-in-1 HEPA filters have an activated carbon granule layer for VOC/odor reduction built in to the filter. The 3-in-1 Z Filter should be replaced once every for 12 months and the replacement filter HRF-Z2 contains 2 filters so 1 package will last a year.

Product FAQs

My air purifier is starting to make noise and the air output is less. What is wrong?

The filters may be dirty. High amounts of contaminants can block the pores in the filter and stop the air from moving through it. Replace the HEPA filters and clean/wash the pre-filters.


How to long should I run my air purifier?

The air purifier will be most effective when doors and windows are closed. It is recommended that you run your air purifier while you are at home to help clean the air. If desired or conditions warrant, you may run your air purifier 24 hours a day.


My air purifier randomly switches operating speeds. Is something wrong?

Check to see if the unit is in AUTO Sensing mode. The air purifier will automatically adjust the cleaning level to reduce airborne particles or gases that are present in the room.


When I plug my unit in, I don’t see any lights on the control panel or hear any chimes, what is wrong?

Please ensure the rear door is completely closed. There is an interlock switch that prevents the unit from being powered on if the rear door is not completely closed.
