Do I need filters for machines, vehicles and cars that will be started and driven indoors?

Yes, to protect the people from the harmful carcinogenic and mutagenic dust particles contained in the exhaust gases.  The OEM DPF systems mounted from the factory only have an efficiency of ca 90%, EHC filters have an efficiency of minimum 99%, our filters reduce the emissions of fine and ultra-fine particles significantly and that is why our filter’s still capture a lot is of particles even on engines equipped with OEM DPF’s.  OEM filters are developed and suitable for driving outdoors.

How do I install a filter on an exhaust pipe with a chromed tail pipe?

For a chromed exhaust pipe you inflate a bellow connection. We have suitable and worry free connection for any exhaust type, contact us for advice so we can help you choosing the right solution

How do I know when the filter should be changed?

We have mounted a pressure control or overpressure valve on our filters, that will show when they are full and need to be changed. You can also change your filter after a certain number of times starting the engine. That way you can ensure low backpressure and good flow through the filter. This avoids causing damage on the filter and using more fuel than necessary.

How should I dispose of used filters?

Since it is classified as normal waste, it is perfectly fine to put used filters in with regular combustible waste.

How long does a filter last before it should be changed?

This depends on whether the filter is used on a petrol- or diesel-driven vehicle, the condition of the engine, your driving style and other factors. But these guidelines will give you an idea:

  • With an L20 filter, you can start the engine around 100 times before changing the filter.
  • The lifespan of an HT is counted in hours. It can be used for about 100-400 hours of driving, depending on the model.

PF takes about 1-2 days to install a diesel particulate filter system.

Can I drive with an EHC filter on the road?

No, our P15, L20 and HT filters are made to be used for the personal health protection of the workers. The efficiency of our filters is so high that our filters would create a too high temperature and backpressure if the vehicle were driven on-road.

Can an EHC filter damage the engine?

No, the backpressure in a filter is very low. The pressure monitor on an HT filter is at about the same level as most mufflers.
