All about extraction

See the difference between extraction and ventilation, and why local extraction protects both you and your clients in the salon.

Extraction vs. general ventilation

The two terms are often confused, but they solve different problems.

Ventilation

General air circulation that supplies fresh air and removes stale air, often through a fixed system in the ceiling. It creates a more comfortable indoor climate, but does not necessarily remove vapours or particles where they are generated.

Extraction (source extraction)

A targeted solution where an extraction arm is placed right where the vapour or odour is generated. It removes chemical vapours and particles before they have a chance to spread through the room, significantly reducing both your and your client’s exposure.

They do not solve the same problem. In a salon, I would always recommend both.

What does the law say?

The Danish Working Environment Authority requires sufficient air exchange in all workplaces, and if you work with colouring or perming products, there are limits on how much of the chemical substances may be present in the air. If you are self-employed and work alone, it is not a legal requirement, but personally, I would never go without extraction if I worked with colour or perms every day.

Why source extraction is worth investing in

It is not just about getting rid of the smell. It actively protects you against allergies, respiratory irritation and headaches, while your clients immediately notice the difference a cleaner indoor climate makes.

What you need to know before choosing

Place the extraction as close to the source as possible; that is what determines whether it really works. It is a good idea to choose a model with noise reduction, as some systems can be louder than expected. Filters and hoses must be cleaned or replaced regularly; otherwise, the performance gradually declines without you noticing. See our range of extraction solutions, or let us advise you on what is right for your salon.

In short

Extraction is not just about avoiding unpleasant odours. It is an investment in ensuring that you can still work in the salon ten years from now without your health having suffered from something you could have prevented. If you have questions about extraction or ventilation, write to me.
