HEPA filter for VAX AP03 Air purifier.

Replacement for Part Number 1-1-134511-00.

Less complicated than the original but equally as effective.

Instructions for installation:

Remove front cover from purifier.

HEPA stands for High Efficiency Particulate Air. A HEPA air filter is made up of thousands of extremely fine fibres arranged into a matt to intercept both microscopic particles and larger ones. An air purifier will push air from the room through the filter to remove pollutant particles. By definition HEPA filters can trap close to 100% of the particles in the air that are 0.3 microns or smaller. (Bearing in mind that there are 10,000 microns in a centimetre, a particle 0.3 microns in diameter is really, really tiny.)

Remove black pre-filter and vacuum/remove dust.

Remove VAX filter and discard - unless it will vacuum/remove dust.

Push new filter into place - it's a deliberate tight fit but made to measure.

Turn on unit.

Replace black pre-filter, relying on suction to hold into correct position.

Replace front cover.

Enjoy.
