The Aquaphor A5 filter set includes four replacement pitcher filters, designed to provide long-term protection against contaminants in tap water, especially when it is burdened with rust, sand, and silt.      Each filter contains an increased amount of filtering materials, allowing for extended use of up to 350 liters of water. Additionally, it effectively removes chlorine, improving the taste and smell of the water.    These filters are compatible with Aquaphor pitchers that use B5 type water filters
