According to the instruction manual, the air filter in the BROAN B70DHV should be checked and replaced every three to six months for optimal filtration and efficiency. It is recommended to use a MERV-13 rated filter for the best performance. Operating the unit with a dirty filter can reduce its capacity and efficiency. When replacing the filter, make sure the unit is turned off and follow the instructions provided in the manual to remove and install the new filter correctly.
