How to tell if a Weichai filter is genuine?
To identify genuine Weichai filters, you can start by looking at three core aspects: official anti-counterfeiting verification, packaging details, and the product's own workmanship. As a Tier-1 dealer of Weichai in China, Guohao Filters supplies all genuine Weichai parts. With 5 years of specialized sales experience in Weichai filters, we are here to walk you through four key aspects to help you determine whether a Weichai filter is a genuine part.
1.Official Anti-counterfeiting Verification (Most Authoritative & Highly Recommended)
This is currently the most direct and reliable method to identify genuine Weichai parts. The operation steps are as follows: Search for the official Weichai public account on WeChat → Tap Anti-counterfeit & Red Packet to enter the internal page → Select either Scan to Claim Red Packet or Scan to Verify Authenticity. Genuine parts will come with a random small cash red packet reward. Meanwhile, the authenticity verification page will show the scan count and a genuine product confirmation prompt. If the prompt shows red packet already claimed, the code cannot be scanned, or there is no anti-counterfeit label at all, please stay highly alert. Such products are very likely counterfeits packed in recycled genuine original packaging boxes.Click here to watch the step-by-step guide.
2.Packaging & Appearance Details
Genuine and counterfeit products often have visible differences in their packaging and printing:
Consistency of Numbers: For some filters, the numbers on the outer packaging, inner box, and the filter element itself are consistent, so you can check them carefully. Also, the label stickers are always placed on the top of the box and follow a standard template, as shown in the picture. If the label template looks different, or if the stickers are placed randomly or inconsistently, they are likely counterfeits.
Printing Quality: The printing on genuine packaging is clear, with full and vibrant colors, sharp font edges, and complete product information (including product name, specifications, and manufacturer details). In contrast, counterfeit packaging is often blurry, with dull colors, ghosting, or even typos.
Packaging Material: Genuine boxes are made of thick, tough paper. Counterfeit packaging is usually soft, thin, and easily deformed.
3.Purchasing Channels & Pricing
Authorized Channels: Try to purchase from Weichai's officially authorized dealers, central warehouses, or official flagship stores, and always ask for a formal invoice and warranty card. Beware of Low Prices: Genuine parts have a relatively transparent market price. If a channel's price is significantly lower than the market average (for example, more than 30% lower), it is highly likely to be a counterfeit or a refurbished part.
4.Product Workmanship & Material Quality
Filter Paper Quality: The filter paper of a genuine filter has high density, uniform thickness, neat arrangement, and a very clean surface. In contrast, the filter paper of a counterfeit one is usually thin and sparse. Sometimes, dust and impurities can even be found on the paper before it has ever been used.
Sealing Ring: Genuine filters usually come with a layer of grease (lubricant) on the sealing ring from the factory to ensure a tight seal and smooth installation. Counterfeit products often lack this lubrication entirely.
Casing & Workmanship: The printing on a genuine casing is clear, often even featuring a laser-etched production date and time stamp. The overall workmanship is fine, with no burrs, rust, or deformation. Counterfeit casings have rough printing and may show obvious defects like uneven welds or excess sealant overflow.
Using counterfeit filters not only results in poor filtration and easily clogged oil passages, but in severe cases, it can even cause serious engine wear or failure. We recommend strict quality control during daily maintenance to ensure the use of genuine parts.
