Air purifier maintenance key as haze season looms over Singapore

As haze conditions periodically affect Singapore's air quality, many residents are dusting off air purifiers to protect indoor air. However, the effectiveness of these devices depends heavily on proper maintenance and usage practices, according to air quality specialists.

Filter replacement emerges as a critical factor in sustaining purifier performance. Devices with clogged or degraded filters lose their ability to capture particulate matter, rendering them substantially less effective than newer units. The frequency of filter changes varies depending on local air quality, device type, and usage intensity. During haze episodes when outdoor air quality deteriorates significantly, filters may require replacement more frequently than during normal conditions. Users should monitor filter indicators on their devices and follow manufacturer recommendations to ensure optimal performance.

Operating costs represent another consideration for households running purifiers continuously. Energy consumption varies by model, with larger units and those operating at higher fan speeds consuming more electricity. Despite running costs, many households find the investment worthwhile during haze periods when outdoor air quality makes ventilation unfeasible.

Room coverage presents a practical challenge for flat dwellers. A single air purifier typically covers limited square footage effectively, suggesting that larger residences may benefit from multiple units positioned strategically in main living areas or bedrooms. Placement near windows or in central locations generally improves circulation and coverage.

Experts recommend assessing existing purifiers before haze season arrives, checking filter conditions, and understanding device specifications. Residents should also consider their specific needs, living space dimensions, and budget constraints when determining whether to maintain current equipment or invest in additional units.
