The maximum supply of air purification filters is nearly 2 times larger than the regular figure at Nanjing Blue Sky Filter Co.,Ltd.. When it is the off-season, we would reduce the production and suspend the production line for maintenance wholly or partially. However, we would maintain certain production and would have some goods in stock. This is a basis for the said maximum supply. Then the production would be restored and the supply would be increased and even doubled.

Drawing extensively on the experience in this industry, Blue Sky is able to offer comprehensive products such as cooker hood filters. According to the material, Blue Sky's products are divided into several categories, and refrigerator air filters is one of them.
