How much does cleaning a diesel particulate filter cost?
It depends, the permanent filters can be cleaned. We recommend that you reach out to your EHC contact or your nearest EHC retailer in order to get an accurate price estimate for your filter.
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 a P15 filter, you can start the engine around 200 times before changing the filter.
- 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.
Does the filter eliminate gases?
No, our filters are a particle filter. Some gases are stuck on the particle and stay in the filter. The gas that pass thru the filter is very fleeting and will exit the ventilation that is needed in the room.
How much does a filter cost?

Is it difficult to install a filter?
No, to mount our P15 and L20 filters temporary filters it is easy and quick to install thanks to our specially designed bellows or cones, which are fit directly in or on the exhaust pipe.
A permanent installation of HT will take approximately 4- 8 work hours. HT can also be used for temporary work with a machine, using a less complicated installation.
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.
