Filter Refills for use with the A1 Filter Box Indoor Wall Unit: Four (4) – 8″x 8” white replacement filters. The quantity is sufficient for several uses, often with around a 30-60 day life for each filter. The life of the filter depends on the amount of grease volume, so we recommend checking your filter at least every 30 days. Get the most out of your filters by regularly cleaning hood vents to prevent excessive buildup from hitting the filter during cleanings. Perfect for stocking up at the time of purchase or for ongoing usage.
