Compatible Models：The replacement filter is only compatible with the LEVOIT Superior 6000S Smart Evaporative Humidifier,Please check your machine model before purchase

Function：This gray humidifier filter is made of durable multi-layer collapsible fabric and unique multi-mesh structure to efficiently filter out impurities. The white sponge cartridge traps and filters fine impurities and sediments from the water and reduces water hardness

Note 1：Residue or discoloration on the filter is caused by impurities such as calcium and magnesium ions in the filtered water.Our tests confirm that there is no effect on air quality or humidification efficiency, so use with confidence

Note-2:Due to logistics and transportation time, the white sponge filter may become compressed and slightly yellow in color. This is a normal phenomenon and does not affect the product's performance. Simply take it out and let it restore its original shape on its own

Value Pack：Pack contains 4 x 6000s replacement filters + 2 x white sponge filters. For best results, we recommend changing the grey humidifier filter every 3-6 months and the white sponge filter every 15-30 days (depending on use and environment)
