How do I choose an energy-efficient air shower for my facility?

I was sitting at home and thinking about air shower systems again because my cousin was talking about maintenance and she said even cleanroom machines can lose efficiency if filters are not replaced on time

I checked Alibaba while scrolling on my phone and searched air shower system maintenance cleaning routine long term cleanroom use and I saw many tips like HEPA filter replacement fan inspection air nozzle cleaning and checking door seals some users said high quality filtration systems last longer and keep airflow stable while others said clogged filters can reduce performance and increase energy use if maintenance is delayed and I is trying to understand how factories manage maintenance when air showers are used continuously throughout the day

Now I feel maintenance is not just cleaning but also proper filter management and system checking because even advanced machines can lose effectiveness if not maintained properly and I dont want to think buying a high end system is enough without following regular maintenance routines and timely part replacement

Do you think regular maintenance is more important or machine build quality matters more for long term air shower system performance ?
