How often do I have to replace my air filters?
TOPS MVHR-filters advises to replace your filters every six months and in case of newly built houses every four months. Check your filters on a regular basis and, if necessary, you can clean them using a vacuum cleaner on the lowest setting so your filters won't damage. NB: never clean air filters with water or any other liquid!

How much can I save using a MVHR system?
Compared to a ventilation unit with a regular exhaust system, a MVHR system will save between 300 m3 and 400 m3 of natural gas on a yearly basis. That means - based on a gas price of 0.65 per m3 of natural gas - that you will save between € 195 and € 260. However, a MVHR system does use a bit more electricity, because of the extra supply fan.
