Warranty coverage varies by product. For most items, coverage is provided by the original manufacturer, and iFilters acts as a retailer that can assist with warranty support. Specific terms, including duration and coverage, depend on the manufacturer’s policy.
For iFilters-branded products, such as the iFilters LWH-D, we provide our own warranty: 1 year from the date of purchase, covering replacement parts. In addition to manufacturer or iFilters warranty coverage, we also offer a 30‑day return/exchange window on eligible products per our Returns & Exchanges Policy, and can assist customers with issues during that period.
