Bagless vacuum filters are meant to be regularly cleaned and changed. In fact changed is best. As soon as you turn on the machine all dust, dirt, mold, dander and debris collect in the container and then what is left over passes through the filters immediately starting to clog them up. Of course a huge amount of fine particles don’t even make it through these filters. They go right through the vacuums seams and into your lungs.
My point is–If you are not going to keep the filters clean you might as well put your face in the dust bin and take a deep breath. Not healthy is it? Neither is a bagless.
