Our clean air philosophy

Industrial workplace air quality is a hugely important issue and we approach it with the seriousness it deserves. We listen carefully to your needs. And we measure dust levels in your facility before and after installing our units.

This way we can design a solution to best improve the air quality at your site – and you can be confident it works. Improving air quality at work is not only good for employees’ health, but good for business too.

We’re the largest air cleaning company in the world because we understand your clean air needs.

A tailor-made clean air service concept – our promise to you

Pre-installation survey

We listen carefully to your needs, pin down exactly what is needed, and talk to you about where to install the units and what this involves.

Installation day

We work with you to make the installation as smooth as possible, including organising lifting equipment should it be needed.


We’ll measure your workplace air quality before and after installation so you can see the difference our systems are making.

Regular servicing

We’ll continue to work with you after installation, providing filter changes, engineer visits and system monitoring to optimise air quality at your work.

Peace of mind

Our monthly fee includes filter changes and we don’t charge for extra visits. The units are fully guaranteed, too – just leave everything to us.

Ongoing relationship

Think of our service as an ongoing relationship – supporting you whenever you need us and working with you as your business evolves.

Expert service and years of experience

Our Technical Support Services Team process and analyse air quality measurements from 2,500 customers per year across Europe and the USA. We have been doing this for decades, so you can be sure we’ll recommend the best solution for you. We’ll also show the results we have measured – just to prove it works.
