Air Purifier Maintenance

Cleaning Your Air Purifier

Proper maintenance of your Hunter Air Purifier will help ensure years of trouble free service.

Follow these steps to properly maintain your air purifier:

  1. Approximately every 90 days, the outside of the unit should be cleaned with a soft, damp cloth.
  2. If needed, the front grill can be removed from the unit and cleaned with soapy water. Simply remove the pre-filter before exposing the grill to water.
  3. Follow the instructions in Changing the Pre-Filter and Changing the Filter (pgs. 18 and 19) to determine when and how to replace the filters.

NOTES:

  • The air purifier must be unplugged during the cleaning process.
  • Be sure the unit is completely dry before plugging in and using.
  • Never immerse unit in water.

Changing the Pre-Filter

When the Pre-Filter Counter exceeds 2000 hours (refer to Filter Run-time Counters for additional information pg. 11), the display will automatically switch to the Pre-Filter Display and the Pre-Filter indicator will flash as a reminder that you should replace the prefilter. To maintain proper odor-removing capability and overall filtration performance, the pre-filter should be changed every 2000 hours (approximately 3 months of use). If necessary, the pre-filter can be changed more often. Proper maintenance of the pre-filter will help extend the life of the HEPA filter. Refer to Obtaining Replacement Filters (pg. 20) if you need help finding replacement filters.

To change the pre-filter and reset the pre-filter counter:

  1. First, turn off and unplug the air purifier.
  2. Next, remove the front grill. For Model 30400, place your fingers in the recesses on either side of the top of the grill and pull firmly. For Models 30170/30175/ 30185, gently press in the push tabs until the front grill slides pass them and is released.
  3. The pre-filter is attached to the inside of the grill with hook tape. Pull gently on the pre-filter to removed it.
  4. If needed, use a soft damp cloth to wipe off the grill.
  5. Install the new pre-filter by placing it in the grill and pressing gently on the prefilter so that it adheres to the hook tape. You may notice a few black particles coming off the pre-filter. Those particles are part of the odor-removing activated carbon and will be collected on the filter during regular use.
  6. Install the grill back onto the unit. First, line up the tabs on the bottom of the grill with the openings on the purifier base and then push the top of the grill forward until it is closed.
  7. Fig27Plug in the air purifier. NOTE: This unit will not operate unless the grill is in the correct position. The display will read “door” if the grill is not attached properly.
  8. Finally, reset the pre-filter counter by pressing the DISPLAY key until the pre-filter counter is displayed. Then, hold the FILTER RESET key for 2 seconds. The pre-filter counter will return to zero and resume normal operation.


Changing the Filter

When the Filter Counter exceeds 8000 hours (approximately 1 year of use), the display will automatically switch to the Filter Display and the Filter indicator will flash (refer to Filter Run-time Counters for additional information pg. 11). This is a reminder that you should check the filter and replace if necessary. The proper time to change the filter depends usage and the environment. Use the following list to help determine if the filter should be changed:

  • Compare the color of the filter to the color coded chart on the inside of the housing. If the filter color matches the darkest color on the chart, you should replace the filter.
  • If you notice a decrease in air output or an increase in noise at any time during normal operation, the filter may be clogged. Replace the filter to return to normal operation.


To change the filter and reset the filter run-time counter:

  1. First, turn off and unplug the air purifier.
  2. Next, remove the front grill. For Model 30400, place your fingers in the recesses on either side of the top of the grill and pull firmly. For Models 30170/30175/ 30185, gently press in the push tabs until the front grill slides pass them and is released.
  3. Gently pull on the filter to remove it from the unit. While removing the filter, note the direction of the flaps that form the seal. The new filter will be installed with the same orientation. Once removed, the used filter can be discarded.
  4. Remove the new filter from its wrapping and look at the orientation of the rubber seals on the sides of the filter. The loose end of the flap should be facing out as the filter is placed into the air purifier. Press the filter firmly into the air purifier. To avoid damaging the filter media, you should press on the frame of the filter only.
  5. Reinstall the grill by first lining up the tabs on the bottom of the grill with the openings on the air purifier base and then pushing the top of the grill forward until it is closed.
  6. Fig28 Plug in the unit. NOTE: This unit will not operate unless the grill is in the correct position. The display will read “door” if the grill is not attached properly.
  7. To reset the filter counter, press the DISPLAY key until the filter counter is displayed. Then, hold the FILTER RESET key for 2 seconds. The filter counter will return to zero and resume counting.
