How to change pre-filters and HEPA 14 filters

Cleaning a pre-filter

The pre-filter can be rinsed with clean water but must be completely dry before being used again. Any remaining moisture could potentially cause damage to the HEPA 14 filter.

Cleaning and changing times

• Pre-filters are to be replaced every 300 hours and HEPA filters replaced every 3,000 hours.
• Clean all external surfaces frequently.
• The particle sensor should be cleaned every 2 months.

Please refer to the next 7 steps on how to clean the Rediair pre-filters, air outlet and particle sensor.

NOTE: Before first use, the Rediair filters must be removed from their protective packaging, making sure the retaining straps point outwards before installation.

WARNING: Before dismantling Rediair to perform filter maintenance/replacement, perform hand hygiene. Follow local guidance on the use of appropriate PPE.

WARNING: Always unplug the Rediair before dismantling the device to perform filter maintenance/replacement.
