Category Maintenance
A grey pre-filter covered in lint is often the first sign that an air purifier needs attention, not replacement. This category deals with the routine work that keeps a unit moving air properly: vacuuming washable screens, changing HEPA and carbon filters on schedule, cleaning dust from vents, checking indicator lights, and handling sensor issues. It also explains what should never be washed, why unofficial replacement parts can affect performance, and how seasonal pollen or pets can shorten service intervals. Regular upkeep protects airflow, limits odours, and helps the purifier deliver the particle reduction it was bought for.
