Oransi Air Purifier Filter Replacements Guide

Oransi offers easy maintenance to replace filters for our air purifiers, and we want to make these instructions as easy as possible for you. Below we’ve listed out step-by-step instructions on how to access and replace the filters, and other components, for each of our air purifiers. 

Each Oransi device has an indicator light that signals when it might be time to change your air purifier filter. While there are ways to prolong the life of your filter through regular cleaning, it’s important to follow the directions below to check your filter. In general, we suggest purchasing new filters when you can no longer see white material on the HEPA filter. 

Simply search for the device you own below to learn how to easily replace your filters and air purifier components to maintain fresh clean air in your home!

  2. Remove the HEPA filter.
  3. Use a screwdriver to remove the two screws and detach the UV lamp cover. Here is a helpful video on how to replace the UV lamp.
  4. Grasp the UV lamp and pull it straight out from the lamp socket. We recommend reaching in toward the base since it is easier to remove from here than pulling on the end of the lamp.
  5. Take a new UV lamp and insert it into the lamp socket. Simply press in on the end of the glass lamp to snap into place. Re-install the UV lamp cover (the large metal face should be above the UV lamp and align the two screw holes with the back of the air purifier), then replace it with the new HEPA filter and new pre-filter and rear cover.
