Dryer filters: demand set to grow driven by refrigerant transition

The global market for dryer filters is expected to grow steadily between 2026 and 2035, supported by the transition to low-global-warming-potential (GWP) refrigerants and the expansion of refrigeration and air conditioning systems. This emerges from a recent report by IndexBox, which notes that the sector will enter 2026 with broader demand, more disciplined supply chains, and increasingly regionally diversified production.

Dryer filters are essential components in refrigeration, air conditioning, and industrial cooling circuits. They play a key role in removing moisture and contaminants, protecting compressors, and ensuring system reliability. Market growth will be closely linked to the development of major end-use sectors such as commercial HVAC, the cold food chain, industry, and automotive.

A decisive factor will be the gradual phase-out of high-GWP HFCs under international agreements such as the Kigali Amendment, which is accelerating retrofits and new installations compatible with alternative refrigerants. This transition will require dryer filters designed for new refrigerant blends while maintaining high purity standards in the circuits.

Demand will also be driven by rising global temperatures, the spread of air conditioning systems in emerging economies, and the expansion of cold-chain logistics for food and pharmaceuticals. At the same time, stricter energy-efficiency regulations and the growing adoption of heat pumps in Europe and North America will further support the use of these components.

According to the scenario outlined by IndexBox, the market will not experience sudden spikes but rather progressive, stable growth, driven by equipment replacement cycles, technological upgrades, and regulatory deadlines. Key drivers include urbanization, the development of commercial buildings with HVAC systems, the expansion of the cold chain, and growth in automotive production.

However, some factors may slow growth, including the long lifespan of high-quality dryer filters, which reduces replacement frequency, economic volatility that can delay investments, and strong price competition among manufacturers. Despite these challenges, the sector is expected to grow slightly faster than overall industrial production, due to the essential role of dryer filters in maintaining and ensuring the reliability of refrigeration systems.

The industrial, commercial, logistics, freezing, and cryogenic refrigeration sectors will gather at REFRIGERA, the international industry event, to be held at BolognaFiere from November 10 to 12, 2027.
