Filters for Air-Conditioning and Ventilation Systems
Lombarda Filtri is a company specialized in the production and distribution of filters for air-conditioning and ventilation systems, designed to ensure reliable and efficient air treatment in civil and industrial environments, including controlled mechanical ventilation (CMV) systems.
Production of High-Efficiency Filters for Air-Conditioning and Ventilation Systems
Lombarda Filtri designs and manufactures filters engineered to ensure high air quality and protect indoor environments and their occupants.
Advanced technologies and selected materials allow the production of filters capable of effectively capturing coarse dust and fine particulate while maintaining reliable performance over time.
These solutions are suitable for industrial AHUs, tertiary-sector HVAC systems, and civil and residential installations, including CMV systems, helping reduce maintenance costs and improve overall energy efficiency.
Filter mats for air pre-filtration in civil and industrial systems, ideal for retaining coarse dust and protecting subsequent fine filters.
Flat or corrugated filter cells with synthetic, fiberglass or metallic media and cardboard or metal frames, with efficiencies from ISO Coarse 35% to ISO ePM10 50% and low pressure drops.
Rigid or soft pocket filters with synthetic or micro-glass fibre media, with classes from ISO Coarse 50% to ISO ePM1 85%, for particulate control.
HEPA and ULPA filters, individually certified according to EN 1822, for systems where air purity is critical, such as healthcare or industrial environments.
Our Guiding Principles
Ecology
Filter mats used in filter cells are mainly thermobonded, free of binding resins, reducing environmental impact. All filters can be supplied in versions suitable for easy disposal through incineration, simplifying logistics and waste management.
Flexibility
Our organizational structure and production equipment allow us to supply filters in non-standard dimensions and small batches, meeting replacement needs in civil and industrial systems.
Quality
Modern equipment, in-house R&D, qualified suppliers and an ISO 9001-certified quality management system make Lombarda Filtri a reliable partner for air filters compliant with major industry standards.
Who We Are
Lombarda Filtri is an air-filtration company composed of professionals with over 40 years of experience.
Quality is a continuous commitment to improving our products. Modern and efficient equipment—often developed through extensive internal R&D—qualified suppliers and an ISO 9001-certified quality system make us a reliable partner.
Filters for Every Sector
Lombarda Filtri’s filters meet the needs of hotels, hospitals, offices, museums, shopping centres, industries and residential buildings, where indoor air quality is essential for comfort, safety and environmental protection. This includes buildings equipped with controlled mechanical ventilation (CMV) systems.

Hotels
In hospitality environments, air-treatment filters—whether centralized AHU systems or local fan-coil units—help ensure cleaner air in rooms and common areas, supporting high comfort levels and healthy indoor conditions.
Certified Air Filter Manufacturers for Efficient and Safe Systems
Experience and Development in Air Filtration
With decades of experience, Lombarda Filtri offers a wide range of filters suitable for different HVAC configurations and applications.
We invest continuously in research and innovation to provide tailored solutions for civil and industrial environments.
We collaborate with major industry players to develop advanced filtration systems, ensuring certified quality, operational reliability and personalized service.
Air Filters Compliant with Standards
Lombarda Filtri’s filters are manufactured using advanced technologies and selected raw materials to ensure certified performance according to standards such as EN ISO 16890 and EN 779 (still widely referenced despite its withdrawal).
For applications requiring very high air purity, HEPA and ULPA filters are produced in accordance with EN 1822 and EN ISO 29463, which define test methods and performance classes for high-efficiency filtration.
Filters designed for gas-phase contaminant removal are tested according to EN ISO 10121, specific to molecular filtration systems.

Frequently Asked Questions
Frequency depends on filter type, efficiency class, environmental conditions and operating hours. Many guidelines suggest inspections every 3 months and replacement every 6–12 months, with shorter intervals in dusty or polluted environments.
– increased pressure drop
– reduced airflow
– higher fan energy consumption
– perceived decline in air quality (odours, dust)
Many HVAC systems include differential-pressure alarms to schedule replacement.
Yes. In addition to centralized systems for new constructions, decentralized CMV units exist for retrofits, requiring only wall penetrations and minimal ducting. The choice depends on layout, budget and energy-performance goals.
