Levoit UK offers three verified filters in this catalogue for the Core 300, and all three share the same confirmed appliance fit while targeting different priorities. HEACAFLVNEA0038 is the standard replacement and is the general-purpose starting point for routine dust, pollen and household use. HEACAFLVNEA0040 is the toxin absorber variant, positioned for smoke, smog, volatile compounds and stronger chemical or cooking odours. HEACAFLVNUK0107Y is the pet allergy variant, intended for homes where fur, dander and pet-related odour are the main concern. A specialised filter is not automatically “more compatible” or universally better: the model fit is confirmed separately, while the choice of media depends on the air problem. Before ordering, read Core 300 on the purifier label and compare the full SKU, including the UK letters where present. Do not choose by colour or a similar product photograph alone. If weak airflow is the symptom, first check whether the current filter is blocked, wrapped or overdue and whether the inlet is clear. Replacing a clean filter with a different specialisation will not repair a fan, obstructed intake or electrical fault.
