West, which is probably not well known, is a guangzhou self-made brand, founded in 1994 and a relatively young brand in the country. Thanks to the growing demand for high-quality products in the domestic automobile filter market and the mature brand consumption concept, in 2002 wester car filters joined forces with the japan east guangji society to improve the quality of wester products, which are also air-conditioning filters containing activated carbon, with the combined advantage of technical equipment management at the japanese auxiliary plant, and paper filters with paper stale structures are made up of three layers, with active carbon layers caught between two layers of fur. West is dedicated to expanding the chinese market to provide a full range of varieties in the domestic market. However, because of its general domestic visibility and the fact that it is now technologically advanced and that its products are up to date, its sales are also moderate, but its price is low, its quality is good in domestic production, and it is better suited to its economic clients。
