INTRODUCTION

The HEPA 500 uses a combination of airflow and filtration to

create cleaner air. The unit draws air through two types of

filters – a pre-filter and a HEPA filter. The first stage of filtration

captures larger particles. When fitted with the optional

Activated Carbon Filter, the first stage can also adsorb a wide

variety of odor compounds. The second stage of filtration

captures much smaller particles down to 0.3 microns.

Why is the change light on my Dri-Eaz DefendAir F284 illuminated?
- C
  Christine WalshAug 4, 2025
  The change light on your Dri-Eaz Scrubber illuminates for the following reasons: * The primary (HEPA) filter is full, so you should replace the HEPA filter. * The air intake is restricted due to bends, kinks, or excessive length of ducting. To resolve this, eliminate bends/kinks in the ducting and reduce the ducting length.

  If your Dri-Eaz Scrubber isn't working, here's what you should check: 1. Ensure the unit is properly plugged in and that there is power at the outlet. 2. Make sure the switch is turned on. 3. Verify that there is power at the supply outlet; reset the supply circuit breaker or GFCI if necessary. 4. Check if the GFCI has tripped; reset the unit's circuit breaker or GFCI.
