These carbon filters are the genuine replacement filters for your Air Cleaner model EAP 300. The clean air that your Air Cleaner releases into your home is a result of filtering incoming air through filters. The carbon filter traps large particles such as dust, pet hair and lint. It absorbs odour causing gases like cigarette smoke, organic decay and cooking. The Cleancel™ antimicrobial coating effectively reduces bacteria and fungi in the air you breathe and removes odours created by microorganisms. To ensure your Air Cleaner continues to release pure clean air you need to replace the carbon filter regularly. It is recommended that you change your Air Cleaner filters every 3 months. This 4 pack will provide you with a 1 year supply of fresh clean air. This pack contains 4 carbon filters with reference: EF 118To ensure the best performance of your Air Cleaner, you may want to change the HEPA13 Filter which is available here.
