Guangzhou Longhuilong Filter Co., Ltd

Most suppliers in the filter and dust collection space are newer, with operations starting in the last 10 years. Guangzhou Longhuilong Filter Co., Ltd. has been in business since 1975, which means they have decades of experience and likely deep industry knowledge. Their product range covers filter bags, dust collectors, machinery, and filter aids — a full suite that supports both small and large industrial setups. The lack of verification on work email, phone, and business documents raises a red flag for buyers who need to confirm legitimacy before placing large orders. Without verified contact details or documents, it's harder to verify their operations or respond to urgent inquiries. Buyers should request additional proof, such as a company registration or product sample, before committing to any purchase.
