Levoit Vital 100S-P: distinguish the washable pre-filter from the main filter
The Vital 100S-P separates a washable pre-filter from its main particle filter and carbon layer. Do not treat the entire assembly as washable.
On the Levoit Vital 100S-P, washing a filter does not mean washing every layer. The manufacturer identifies the pre-filter as washable, while the main particle filter and activated-carbon layer have different functions. Use the model manual for maintenance and consider the stated 6–12-month replacement interval as a guide, not a universal promise.
