Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.

Provided herein is an eco-friendly artificial leather for an interior of an automobile and a manufacturing method thereof. The eco-friendly product is manufactured using a method that is compatible with various environmental regulations such as reduction of greenhouse gas emissions. The artificial leather includes a bio urethane-containing skin surface layer which uses biomass-derived components extracted from vegetable components, a solvent-free bio urethane adhesive layer, and a bio fiber base layer. The layers are sequentially stacked to minimize the use of organic solvents and components that are harmful to the human body.
