Airpura replacement prefilter — genuine two-pack

The Airpura Replacement Prefilter is the first filtration layer inside compatible Airpura air purifiers. It captures larger airborne debris before that material reaches the carbon and HEPA filters, helping the main filters operate as intended.

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

The cylindrical prefilter surrounds the inner filters and can be vacuumed through the purifier’s exterior grille for routine maintenance. This product contains two genuine replacement prefilters.

Compatible Airpura models

Available for R400, V400, R700, V700, F700, C700DLX, and UV700. The T700DLX uses the specialized TarBarrier instead of this standard prefilter.

Where it goes

The prefilter lines the outer wall of the filter chamber, around the carbon canister. Select the size for your purifier model.

Specifications and maintenance

Package 2 prefilters
Function Captures larger particulate matter before the main filters
Routine care Vacuum from the exterior grille about monthly or as conditions require
Suggested replacement About every 12 months
Model selection Required; 400 Series and 700 Series sizes differ

Replacement intervals are manufacturer guidelines. Actual service life varies with air quality, operating speed, and hours of use.

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 prefilter
  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. Remove the central particle filter and carbon canister, retaining any fitted particle wrap and bands. Remove the old outer prefilter.
  4. Place the lower felt gasket flat at the bottom of the chamber and position the outer prefilter or TarBarrier against the chamber wall.
  5. Roll the filter slider into a spiral, insert it inside the outer filter and open its top into a slight funnel.
  6. Hold the correct carbon canister straight and lower it through the slider. Lift the slider out with both hands, allowing the canister to settle at the bottom. Remove and retain the slider.
  7. Insert the correct True HEPA or HEPA Barrier assembly inside the carbon canister. Retain any fitted particle wrap and its securing bands in their original positions.
  8. 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.
  9. Return the purifier upright. Reconnect power only after the filter chamber is closed, with the control switched off before plugging in.

Cleaning between replacements

Switch off and unplug before cleaning. Use your vacuum’s brush attachment to clean the prefilter through the outside grille, moving slowly around the mesh surface. Clean monthly or more often when needed.
