Which air filter fits your situation?

Answer two questions. You will see straight away which filter medium usually fits your situation. You can then request a quote, with your answers already filled in.

Question 1: What must come out of the air?

  • Odour
  • VOCs, for example from solvents
  • Hydrogen sulphide (H2S)
  • Ammonia (NH3)
  • Corrosive gases around electronics
  • Fine and coarse dust
  • I don't know

Question 2: How much air passes through the filter per hour?

  • Up to 1,000 m³/h
  • 1,000 to 10,000 m³/h
  • 10,000 to 50,000 m³/h
  • More than 50,000 m³/h
  • I don't know

Initial advice

For question 1

Your answer

First advice

Odour

That depends on the substance. Odour usually comes from VOCs, hydrogen sulphide (H2S) or ammonia (NH3), and each substance needs its own medium. See Odour control.

VOCs

Activated carbon without impregnation. VOCs stick to the carbon physically. See Activated carbon filters.

Hydrogen sulphide (H2S)

Activated carbon with an alkaline impregnation. H2S is an acid gas and is then bound chemically. See H2S.

Ammonia (NH3)

Activated carbon with an acid impregnation. Ammonia is an alkaline gas and is then bound chemically. See Ammonia.

Corrosive gases around electronics

Chemical filter medium: alumina granules with an impregnation that binds the gas. A measurement with copper and silver coupons first shows how corrosive the air is; the target is class G1. See Corrosion protection.

Fine and coarse dust

A dust filter, chosen by its class under ISO 16890. See Dust filters and HEPA.

I don't know

Then we work it out together with your request. How a test with a rented filter unit works is explained under Filter unit rental.

For question 2

Your answer

First advice

Up to 50,000 m³/h

The largest single filter in the range is suitable for 50,000 m³/h.

More than 50,000 m³/h

Several filters are placed in parallel or in series, up to 100,000 m³/h.

I don't know

We work out the flow rate with you when you send your request.

This advice is a first direction. For a quote we also look at the concentration, the temperature, the relative humidity and how long the filter must work before the medium is replaced.
