Across the Entire BOGE Filter Range

Four qualities that define
every BOGE filter

Lowest differential pressure
Innovative element fleeces and deep-pleated design minimise flow resistance across the full service life, directly reducing energy consumption and operating costs.
Certified efficiency
All BOGE filters are tested and certified to stated efficiencies — from 99.925% on pre-filters to 99.9999% on microfilters. Consistent, verifiable performance for compliance and quality management.
Suitable for food & pharma
Standard range filters carry FDA Title 21 CFR certification, making them suitable for direct use in food, beverage, pharmaceutical and cosmetics production environments.
Cleverly combined
Filters can be combined in series using wall brackets or coupling sets with no cross-sectional restriction. Replacement elements are downward compatible across series for easy maintenance.
Selection Guide

Which filter for
