Air filter

A health issue

With the increasing popularity climbing sees comes crowded climbing gyms and increasing magnesium dust levels.

More and more articles can be found online. Some referreing to dust levels as high as 100 times above EU limits (Dust Exposure in Indoor Climbing Halls) Other articles mentioning lung function declining 20% after just a few hours of exposure (Lung Function and Dust in Climbing Halls).

Long before the dust is visible to the human eye, the limit values are exceeded. Dust particle sizes normally range from 0,1 micrometre to 10 micrometre. The level of "ultra fine dust" particles smaller than 0,1 micrometres is worrying as they enter the body through the lungs, but translocate to essentially all organs. The fine dust particles between 2,5 to 10 micrometres is where you have the highest concentrations in climbing gyms. These particles cause pulmonary inflammation but also retains long in the lungs.


The technology used in the ClimbLab filters is effective for ultra fine as well as fine dust particles. 

ClimbLab technology

With the ClimbLab solution you will be able install the filters close to the source. And as the air filters come with a high air flow fan you will be able to create the needed draft / suction effect to lead the particles to the air filter, where they are collected.

At the same time, you will be able to raise the air exchange rate for your gym to a higher level. If your gym is lacking central ventilation or has a low air exchange ratio <3 you will still be able to reach an acceptable level.

Our electrostatic filters are tailored to capture magnesium dust particles from 0,1- <10 micrometres.  We have tailored parameters as airflow and electrostatic voltage.

As our air filters use electrostatic filters, we offer the lowest possible operation cost. When the filter is full you simply just take out the cassette and rinse it with water and soap. 

Our filters come with a very low power consumption as there is no pressure drop across the filters and therefore less need for a large fan. One filter can be operated for as low as 20 Euro a year.

They come with a low noise level. Once installed you will not be able to hear them operate, as the level is as low as 52 dBA.

Why central systems fail

Central ventilation systems are often designed according to normal standards offering 3-5 times air change of the room volume pr. hour. But heavy polluted areas require as much as 9-12 air changes per hour.

Central systems are normally installed at the ceiling, but fine dust particles around 5-10 micrometres are relatively heavy so they will simply just fall to the mattresses and floors and keep being resuspended as people bounce on the mattresses. Central systems often lack the needed throw / draft to lead the particles to the filters where they can be collected.

The easiest way to control the dust level is by source control and to capture the dust as close as possible to the source (you). 

This is why the ClimbLab system comes with different installation possibilities. (wall mount, standing, hanging and the floor suction). You simply need to tailor the installation to your gym and the "Hot spots" where people climb and chalk up the most.

Proven results

At ClimbLab we believe in data, especially when you cannot see those fine dust particles before it's a massive problem. We gurantee a 60-70% reduction of your dust level.

We offer to do dust level measurements before and after the installation, or you can simply lend some equipment by us and do the measurements yourselves.

By measuring the before and after dust concentrations you can be absolutely sure that you have bought a system which actually works. This is your guarantee.

Installation options

Find your climbing gym layout below, and see how to install the filters. Examples below are based on our model 1.

Depending on the ventilation in your gym you might need model 2 or 3 as they provide a higher air exchange rate. Reach out to us for further advice.
