Fits these models
Does NOT fit — commonly confused
Levoit does not agree with itself here
Levoit identifies this 4-pack with two different codes. Its Amazon listing gives part number LRW-S602S-AUS, while the box in Levoit's own store photo reads LRW-S601S-BUS. Each matches one of the two Superior 6000S revisions we have seen documented: LEH-S601S-WUS in Levoit's manual, and LEH-S602S-WUS on Amazon's listing for the humidifier.
Levoit says the gray filter fits and performs like earlier filters, but it does not say whether the two codes are interchangeable. Before ordering, read the model number on your humidifier's rating label and the code on your current wick box, and match them.
Variants Levoit sells
Units we have researched that take this wick: Levoit Superior 6000S .
Four gray wick filters that sit in a frame above the Superior 6000S tank. A pump keeps them wet and the fan blows air through them, so the water evaporates from the wicks and the machine humidifies without mist.
Levoit says the gray design performs like its earlier filters, and that discoloration from water impurities is normal and, by its own testing, does not affect humidification.
Every 3–6 months, depending on weather conditions and water quality, per its Superior 6000S manual. The wicks are washable in between.
Levoit's filter page says the gray filter can be used for over 3 months. The Check Filter light is a reminder to inspect the wicks; the manual says you may not need to change them yet when it comes on.
Steps as documented by Levoit. If the light stays on after this, the troubleshooting below covers why.
Levoit's Superior 6000S manual says not to use third-party water filters or water treatment liquids in the humidifier. That instruction names water filters, such as the sponge, not the wick filters.
Levoit's Amazon listing describes these wicks as a genuine accessory that protects your humidifier. The manual's warranty lists filters among parts that wear out and are not covered.
That is Levoit’s stated position, reported as theirs. We have not tested third-party filters and make no claim about how well they work.
| Symptom | Why it happens | What to do |
|---|---|---|
| The Check Filter light is on but the wicks look fine. | The light is a reminder to check, per Levoit's manual. | Rinse and brush the wicks, run Dry Mode, then reset. |
| The wicks are stained. | Impurities from the water collect on them. | Levoit calls it normal; replace every 3–6 months. |
| Amazon sent a different Levoit filter. | The variation menu mixes several models' filters and pads. | Select the Superior 6000S filter and check the part code. |
| Room humidity is not rising. | Fan speed too low for the space, per Levoit. | Use a higher fan speed; large spaces take longer. |
| The humidity reading looks wrong. | Sensor near a wall or corner, damp, or dusty. | Keep it 12 inches from walls; let the sensor dry. |

Checked against the manufacturer's own pages. We did not test this filter. Nothing here is a measurement of ours: every figure is either documented by the manufacturer or published by an independent standards or testing body, and where the two disagree this page says so.
