Indoor Wall Unit Filter Refill Pkg

• Filter refill package for the A1 Filter Box Indoor Wall Unit
• Enjoy extra filters with your initial purchase or refill your supply as it runs low
• Filter lasts 30-60 days on average when hood filters are consistently maintained
• A working filter is vital for capturing grease and chemical runoff during hood filter cleaning

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.
