need to test it if it can absorb odors

After placing the order, I was constantly worried about the transportation and the condition of the product. But I felt relieved after receiving the air filter. The transportation was smooth, and the packaging was exquisite. When in use, the purification effect is remarkable, making the air fresh. When I consulted the customer service, their responses were professional and prompt. I have to say that the transportation, packaging, service, and quality are all superb. I'm very satisfied!
