Airpura H13 True HEPA replacement filter

The Airpura Replacement True HEPA Filter restores the main particle-filtration stage in compatible Airpura purifiers. It is rated 99.97% efficient for airborne particles at 0.3 microns.

Choose by purifier model: Match the model printed on the serial label on the back of your Airpura unit to the variant selector before ordering.

What this replacement filter does

This is the primary fine-particle filter for dust, pollen, pet dander, mold spores, smoke particles, and other airborne particulate matter. It does not replace the purifier’s carbon filter, which handles gases and odors.

Compatible Airpura models

Available for R400, V400, R700, V700, F700, and UV700. C700DLX and T700DLX use a HEPA Barrier instead of this H13 True HEPA filter.

Where it goes

The True HEPA filter sits inside the carbon canister as the central particle filtration stage. Match the replacement to your purifier model and retain any fitted particle wrap in its original position.

Installation steps

Match the replacement to the model on the purifier’s rear label. Switch off and unplug before starting; retain all felt gaskets and screws for reassembly.

Replacing the True HEPA filter
  1. Switch off and unplug the purifier. Support the unit securely while turning it over to access the base.
  2. Remove the four retaining screws, lift off the bottom cover and set aside the upper felt gasket. Keep the screws and gaskets for reassembly.
  3. Lift the old True HEPA filter out from inside the carbon canister. Leave the outer prefilter and carbon canister in their fitted positions.
  4. Where a particle wrap and elastic bands are fitted around the old HEPA filter, transfer them to the replacement in the same position.
  5. Slide the correct replacement True HEPA filter inside the carbon canister.
  6. Replace the upper felt gasket. Align the indentation in the bottom cover with the center of the particle filter, refit the cover and tighten all four screws.
  7. Return the purifier upright. Reconnect power only after the filter chamber is closed, with the control switched off before plugging in.
