4-pack of water purifier filter cartridges for Sage coffee machines - compatible with Sage Barista Express Pro Touch models Ses875/ses878/ses880/ses990/ses980/bes810/bes920 - Products will be shipped according to the color or size shown in the main image on the product page. Enhance coffee flavor - Activated charcoal has well-developed pores and excellent adsorption capacity, effectively removing impurities, scale, odors, residual chlorine, volatile substances, and heavy metals (lead, mercury), ensuring deeper water purification. Sodium-free exchange resin softens water while retaining minerals essential for maintaining a balanced diet and healthy lifestyle. NSF TV certified - Certified according to EU Regulation 1935/2004/EC and DIN 10521:2009. The Sage water purifier filter cartridge housing is made of BPA-free plastic, and the internal adsorption filter layer is filled with natural activated charcoal shell carbon and cation exchange resin. Microporous mesh and microporous PP cotton prevent fine particles from entering the purified water. Protect your coffee machine – Sage water purifiers absorb sediment from tap water, effectively reducing the risk of scale buildup in your coffee machine's internal pipes. Friendly reminder: We recommend replacing the water purifier filter every three months. (Replacement reminders can be set on the filter.)
