The Ultimate Wipes Warmer features the patented Ever-Fresh® System which is guaranteed to help keep your wipes the freshest they can be to soothe Baby's delicate skin. The patented Ever-Fresh System works three ways: 1) Anti-microbial: Both the wipe warmer's tub and the Ever-Fresh pillow are treated with an EPA approved additive to inhibit the growth of microorganisms that may cause spoilage, odors and mildew. 2) Non-browning: Keeping wipes moist prevents most discoloration from occurring when wipes are warmed. Over time, additives typically found in baby wipes, cause discoloration as they warm. The Ever-Fresh System effectively insulates wipes from the warming surface, preventing browning. 3) Moisture Retention: The Ever-Fresh System keeps wipes moist by an evaporation and condensation process. Micro pores in the pillow trap and release water as needed to maintain moisture content. The Replacement Pillows are specifically designed micro pore pillow that fits between the heat source and wipes, keeping wipes moist and fresh. Guaranteed to help keep wipes the freshest they can be to soothe baby's delicate skin.
