OEM vs Compatible Replacement Filters: What to Check
A buying checklist for deciding when OEM filters are worth it and when compatible replacements may be acceptable.
OEM parts reduce fit and warranty uncertainty, while compatible replacements can lower cost when the fit data is clear. Check certification claims, exact model references, return policy, and whether the part is a filter, bag, brush, or full maintenance kit. Avoid listings that claim broad universal fit without naming your model.
