Pre-Filter Compatible with Blue Pure Air Purifiers

Pre-Filter Compatible with Blue Pure Air Purifiers

This pre-filter is designed for use with select Blue Pure air purifier models. It functions as the outer washable fabric layer, helping capture larger airborne particles before they reach the main filter.

By trapping dust, lint, and pet hair, the pre-filter helps extend the lifespan of the primary filter while maintaining consistent air purification performance.

Made from washable fabric material, the pre-filter is easy to clean and reuse, supporting cost-effective and convenient maintenance.
