Air purifier replacement filters — HEPA, carbon and pre-filters.
Air purifier filters trap dust, pollen, pet hair, smoke and odours, and they become clogged over time, which reduces air cleaning performance, so they must be replaced regularly, usually every 6–12 months. HEPA filters capture fine particles, while activated carbon filters absorb odours and gases. Pre-filters catch larger particles and can often be washed. Check the air purifier brand and model before ordering, as filters are made for specific models. Replacement filters are often cheaper than original brand filters while offering similar performance. Regular filter changes keep indoor air clean.
