Product review (2 stars): Will not last/hold up
These filters are good for single use only.  I generally rinse/clean the filter each week, and it lasts for approximately 3-4 weeks before I need to replace it.  However, this filter does not have the reinforcing metallic woven into it (as several other filters do, including the Best Air filters I just purchased to replace this with: https://www.amazon.com/gp/product/B0085ZIX3S/ref=od_aui_detailpages00?ie=UTF8&psc=1).  Bottom line: once washed it will not retain its shape.  So, it is not a good value/useless after rinsing/cleaning.
