Does the air in the cleanroom become thinner?

Even in the first market study from 2024 with reference year 2023, the German cleanroom market presented itself in impressive form. Over the years, it grew at rates of nearly ten percent annually, making it one of the most dynamic industry sectors of the German economy. Throughout 2024, this momentum cooled noticeably, but by 2025, the market is already picking up again. With a growth of over six percent in cleanroom area stock, the sector continues to develop significantly faster than the overall economy in Germany. For many manufacturing and planning companies, this means one thing above all: full order books and sustained stable demand in a market that shows remarkable resilience against economic fluctuations.

The cleanroom stock in the entire D-A-CH region is also continuing to grow. Although somewhat more modest than in the German lead market, it is still clearly trending upward. Overall, the cleanroom area now reaches approximately 3.6 million square meters. This is the result of the just-completed update study “The German Cleanroom Market 2026 (with D-A-CH excursus).” However, the study reveals more than just rising figures – it also shows that the market is currently reorganizing itself on different levels.

Behind this growth lies a perceptible structural change. Some of the major prestige projects that determined expected order volumes just a few years ago have been postponed or partially canceled. At the same time, a growing portion of new cleanroom capacities is emerging in smaller and medium-sized facilities. Parallel to this, the number of independent operators is increasing, while multi-site operators are growing less strongly than before. The main reason lies in changes along industrial supply chains. More and more companies are compelled to use cleanroom technology to meet requirements for technical cleanliness or precise production conditions. For many of these new operators, however, lower cleanroom classes are not primarily about high-end specialization, but about the most economical implementation possible.

This is where a development begins that could fundamentally change the market. While the cleanroom market was long characterized by highly specialized solutions, a kind of “trading down” is now partly observable. Especially in the rapidly growing ISO classes, new capacities are increasingly being created with more standardized solutions. New operators often do not resort to specialized cleanroom builders, textile suppliers, or service providers for cost reasons. As a result, part of the market growth is shifting increasingly outside established provider structures, such as in in-house cleaning, general wall and ceiling panels, or standard workwear.

At the same time, ISO-classified cleanroom areas are gaining more and more importance. The market is becoming broader and more diverse because more and more industries are deploying cleanroom technology – from the semiconductor industry to medical technology to new applications in industrial manufacturing. An additional noticeable trend is that cleanroom areas are growing significantly faster than the number of employees. The reason for this, partly due to the skilled labor shortage, lies in increasing automation. Robotics or automated production lines are taking over more tasks, while companies simultaneously try to reduce human contamination factors in the cleanroom.

The landscape on the supplier side is also changing. For a long time, the German cleanroom market was considered dynamic but stable – with solid customer relationships and established supplier structures. This phase now seems to be ending. Rising production costs in Germany, weaker development of key industrial sectors, and more difficult export conditions are increasing economic pressure on many operators. Purchasing departments respond with more competition, more tenders, and a much stronger focus on cost. The cleanroom market is thus gradually developing into a more competitive sector, where providers need to reposition themselves, and new players are increasingly trying to gain market share.

How strong this development already is can be seen by looking at the individual submarkets of the cleanroom market, which have now been analyzed in detail in the current study. In the area of cleanroom cleaning, regular re-tendering of spaces has long been routine. But now, other suppliers are also coming more into focus for purchasing departments. This is particularly evident in cleanroom textiles and textile leasing. While in the past the primary supplier of a cleanroom was often set over many years, today more and more operators regularly review and re-tender their supply contracts. The market is thus increasingly developing similarly to personal protective equipment or traditional workwear.

The market structure is also changing in the area of wall and ceiling panels. Especially for large projects and public tenders, mechanisms from the general construction sector are being used more frequently. General contractors and non-specialized cleanroom planners are gaining importance and rely more heavily on suppliers and assembly companies of the cleanroom shell within functional planning. At the same time, the provider landscape is becoming more differentiated – between manufacturers of highly specialized cleanroom panels and providers of solutions originating from other fields, such as cold room construction, which are increasingly being used in cleanroom construction as well.

In the market for cleanroom clothing, the offering continues to be divided into single-use and reusable products. In both segments, increasing concentration on the supplier side is observed, especially pronounced in the reusable segment. Simultaneously, the market is becoming more international. International providers are expanding their presence in Germany, while German companies are increasingly trying to establish themselves in foreign markets.

The dynamics are also shifting in the area of air filtration technology. Besides traditional providers of ventilation systems, more manufacturers are emerging that have developed solutions specifically for cleanroom environments. At the same time, providers of cleanroom shells are increasingly trying to expand their value chain by offering their own FFU systems, thereby strengthening their involvement in both project phases and after-sales business.

The new study thus provides not only an update of the 2024 edition but also a significantly expanded analysis of the cleanroom market. In addition to cleanroom cleaning and laundry, it now examines key submarkets such as wall and ceiling panels, air filtration technology, and textile cleanroom clothing in detail regarding market volume, product structures, and provider shares. A particularly revealing result is that segments where products need to be exchanged regularly generate significantly larger long-term market volumes than those primarily involved in the initial setup of cleanrooms. This is evident, for example, when comparing filter units and FFU systems or single-use versus reusable cleanroom clothing, with their different exchange cycles.

With this expanded perspective, the study provides the clearest picture yet of Europe's largest cleanroom market. It shows where the market is actually growing, where structures are changing – and where new opportunities are emerging. At the same time, it forms the basis for the next step: market research is currently being expanded at the European level to better capture the international dynamics of this highly specialized future market.
