Stay fresh with the Tefal Freshboost Vacuum Blender BL181D65. Exclusive NutriKeep Technology sucks all the air out of the jug before blending to prevent oxidation and preserve the nutritional, visual and taste qualities of your smoothies for longer. The Tefal Freshboost personal vacuum blender preserves up to three times the number of antioxidants- substances that are vital for warding off cell damage, illness and aging. One look and the difference is obvious. All your drinks will have a smoother texture with less foam and separation, stronger flavours and even brighter colours.
