To maintain a good, clean and healthy indoor climate it is important to check and replace your air filters regugarly. At least twice a year depending on your living situation and health. In cities there is more fine dust which means that your filters get more dirty than when living in the country side. And fine dust is dangerous for your health. When we send the new HRV filters it reminds you to check and replace the current dirty filters. You can chose how often a year you want to receive new filters. 2, 3 or 4 times a year.
