The material of the monthly replaceable filter (pollen filter that fits on the bigger dust filter) is made of a relatively hard material which doesn’t seem to collect the dust at all. In fact it didn’t turn black after 3 weeks of using it and in addition I was not sleeping well. The texture of this material feels way different to the original Phillips product. Almost as if it were not permeable. I think one should not compromise one’s health and sleep by buying cheap alternatives. I did not feel comfortable using this product.
