LAVEN Air Filter Oil 1L [Made in Japan] For Wet Sponge Filters Only. Concentrated Type. [Amazon Shipping]

Excellent Penetration: This oil easily penetrates wet air filters.

It does not emulsify with water, resulting in minimal performance degradation and long-term use.

Apply enough so that it covers the entire filter and does not drip when squeezed tightly.
