Aroma Pads 30 Packs, Humidifier Replacement Filters Compatible with LEVOIT LV600S, Classic300S, LV600HH, OasisMist450S Humidifiers, Make The Fragrance Stronger and Longer Duration,White

I have an off brand humidifier and it does have a place to put scent pads and even though my humidifier isn't listed as being compatible, I compared the size of the compartment and thought I'd give them a try. They are a teeny tiny bit long but they are bendable so it fits with a slight ripple to it so I made it owrk. It holds the essential oils of my choise and disperses it out when the humiifier is on. I'm sure the 30 pack will last me throughout the winter as I can use them over and over for awhile. How long before I need to change it? I shall see

It fits my Levoit Humidifier Classic 300s. Although the size and quality are not the same as the original, it still works. You get what you pay for.
