Heat recovery ventilation filters should be changed at least once a year, but this is subject to where you live and the conditions of air quality around your home.
One of the basic principles of an efficient home is to prevent air leakage in the building envelope by sealing up around windows, doors, ECT.
This can be achieved by installing airtight tapes around windows and doors, and airtight membrane in ceilings.
Our main Air tightness products are high quality, German manufactured for making your home airtight.
