Pre-Filter Compatible with Blue Pure Max Air Purifiers

Pre-Filter Compatible with Blue Pure Max Air Purifiers

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

By trapping particles such as dust, lint, and pet hair, the pre-filter helps protect the main filter and extend its service life, while maintaining consistent air purification performance.

Designed for convenience, the pre-filter is removable and easy to maintain, supporting long-term use and cost efficiency.
