1. Quality Assurance Standards
HIFI filters are manufactured to OEM factory standards. Each filter in the range is designed to meet or exceed the original equipment specifications for the vehicle application it covers. Win Store selects and imports HIFI filters based on the following quality criteria:
| Quality Parameter | Standard Applied |
| Filtration Efficiency | Meets or exceeds OEM-specified micron rating for the application |
| Filter Media | Multi-layer synthetic or cellulose media depending on filter type |
| Pressure Differential | Flow resistance within OEM-specified range at operating temperature |
| Burst Pressure Rating | Tested to exceed maximum system operating pressure |
| Sealing & Gasket | Compatible with OEM housing geometry; tested for leak-free operation |
| Dimensional Accuracy | Thread pitch, diameter, and body dimensions match OEM specifications |
| Temperature Resistance | Rated for the operating temperature range of the target application |
All HIFI filters are imported through authorised channels. Win Store does not knowingly stock or sell counterfeit or substandard filtration products.
|
📘 Note HIFI filters are aftermarket products, not OEM factory-branded parts. They are engineered to match OEM performance and are suitable for use as replacement parts during normal servicing. HIFI filters သည် aftermarket ကုန်ပစ္စည်းများဖြစ်ပြီး OEM factory brand မဟုတ်ပါ။ OEM performance နှင့် ညီမျှအောင် ဒီဇိုင်းဆွဲထားပြီး ပုံမှန် servicing တွင် replacement parts အဖြစ် အသုံးပြုရန် သင့်တော်သည်။ |
2. Warranty Coverage
Win Store provides a limited warranty on all HIFI filters against manufacturing defects under the following terms:
| Warranty Aspect | Details |
| Coverage | Manufacturing defects in materials and workmanship |
| Warranty Period | Covers the normal service life interval for the filter type purchased |
| Who is Covered | The original purchasing customer or workshop who purchased from Win Store directly |
| Remedy | Replacement with the same or equivalent HIFI filter code at Win Store discretion |
| Claim Timeframe | Warranty claims must be submitted within 30 days of discovering the defect |
| Proof Required | Purchase receipt or invoice from Win Store showing the HIFI code purchased |
A manufacturing defect is defined as a fault in the filter arising from the production process — including but not limited to: a defective gasket seal, collapsed filter media, incorrect thread forming, or structural failure under normal operating conditions.
|
💡 Tip Keep your Win Store purchase receipt. It is required for all warranty claims and can also be used to confirm the correct HIFI code if you need to reorder the same filter in the future. Win Store ဝယ်ယူမှု ဘောင်ချာကို သိမ်းဆည်းထားပါ။ အာမခံ claim တင်ရာတွင် လိုအပ်ပြီး နောင်တွင် တူညီသော filter ပြန်မှာသောအခါ HIFI code ကို အသေချာ သိနိုင်ပါသည်။ |
3. What the Warranty Does Not Cover
The following situations are excluded from warranty coverage:
▸ Normal wear during regular service use — filters are consumable items and are expected to be replaced at the recommended service interval.
▸ Damage caused by incorrect installation, including over-tightening, forcing a mismatched filter, or failure to follow the installation guide in H09.
▸ Use of an incorrect filter code — installing a HIFI filter that does not match the vehicle application.
▸ Damage caused by contaminated or low-quality engine oil, fuel, or coolant.
▸ Filters that have been modified, cut, or disassembled after purchase.
▸ Filters used beyond the recommended service interval.
▸ Damage caused by external factors including road debris, accidents, flooding, or fire.
▸ Filters purchased from unauthorised third-party sellers who are not Win Store.

⚠️ Warning Purchasing HIFI filters from unauthorised resellers or informal market sources (e.g., roadside stalls, unverified online sellers) may result in counterfeit or substandard products. Win Store warranty only applies to filters purchased directly from Win Store or its authorised channels. ခြင်ပြင်ကောင်ပုံဆိုင် သို့မဟုတ် မတရားသော online ရောင်းသူများထံမှ HIFI filters ဝယ်ယူပါက အတုမြောင်မြောင် ကုန်ပစ္စည်းဖြစ်နိုင်သည်။ Win Store ၏ အာမခံချက်သည် Win Store ထံမှ တိုက်ရိုက် ဝယ်ယူသော စစ်ထုတ်ကိရိယာများသာ အကျုံးဝင်သည်။ |
4. How to Make a Warranty Claim
1 Stop using the defective filter. If it is an oil filter with a leak, switch off the engine immediately and check oil level.
2 Collect the following information before contacting Win Store: (a) your purchase receipt or invoice showing the HIFI code and purchase date; (b) the HIFI code and lot number printed on the filter; (c) your vehicle details (make, model, year, engine code); (d) a clear description or photograph of the defect.
3 Submit a warranty claim through one of these channels: Zendesk Help Center at support.winautoparts.com (preferred — creates a trackable case), or by contacting the Win Store sales team by phone/Viber.
4 Win Store will assess the claim. We may request the defective filter be returned for inspection. Do not discard the defective filter before your claim is assessed.
5 If the claim is approved, Win Store will arrange a replacement filter. If the exact code is out of stock, we will notify you of the expected restock date or offer an equivalent alternative.

5. Authenticity & Counterfeit Protection

| Filter Labelling | HIFI code and specifications clearly printed on the filter body or label |
| Gasket Quality | Rubber gasket should be uniform, smooth, and free from tears or rough edges |
| Media Appearance | Filter media should appear uniform and undamaged when viewed through the end plate |
