- Season (more frequent cleaning needed during peak usage)
As a general rule, inspect your filters monthly and clean them when you notice visible dust buildup.
Cleaning Methods:
- Light dust: Gentle brushing or vacuuming
- Moderate dirt: Shake outdoors, then vacuum
- Heavy soiling: Wash with warm water and mild detergent, then air dry completely
Note: Never reinstall damp filters as this can promote mould growth.
Replace your dust filters when:
- They show signs of deterioration or damage
- They remain dirty after thorough cleaning
- They've been in use for more than 2 years
If you're unsure about any cleaning procedures or prefer professional assistance, consider air conditioning cleaning services to ensure your unit is maintained properly.
Air Purification Filters
Modern air conditioners often include specialised air purification filters. These come in several varieties:
- Ionising filters (release negative ions to trap particles)
- Carbon filters (absorb odours and harmful gases)
- HEPA filters (capture microscopic particles)
- Enzyme filters (break down bacteria and allergens)
Unlike basic dust filters, most air purification filters cannot be cleaned effectively. They typically require replacement every 6-12 months, depending on the manufacturer's recommendations and usage patterns.
| Filter Type | Cleaning Method | Replacement Frequency |
|---|---|---|
| Dust Filter | Washable | 2-3 years |
