    Replacement works well, but I don’t recommend washing, November 3, 2014

    Verified Purchase(What’s this?)
    Good replacement and vital – I do not wash mine though. I remove the lint by hand that builds up – mostly in the center of the filter and then take it outside and bang the filter against a tree or wall depending on which way the wind is blowing. I tried washing these, but the lint clumped up inside the fabric and I couldn’t get rid of it. I’m sure it depends on what kind of carpet or flooring you have as to what ends up in this filter, but for me, tapping out the dust worked much better.
