Dear Customers,

We are so sorry to issue this price increase notice. However, we have no other choice when considering the following two real situations:
1. GI steel and Aluminum material cost goes up sharply by 30%-40%. And the government just had meeting one week ago with several big steel companies to keep the price steady rather than going up continuously.
2. The RMB to USD exchange rate changed from 6.5(3 months ago) to 6.3(half a month ago).
So if the more metal used in a filter, then the price will be influenced more.
Kindly noted. We will try to keep the former price as much as we can. Hope we can work together to go through this hard period.
