Terribly THIN & see-thru. Bad pre-filter.
These are thinner than other pre-filters I have bought. I can hold it up to the light in the garage and I can see thru and make out the cabinets outline and doors.As a result, I have to use 2 of these to truly protect my Hepa filter. Otherwise the Hepa will get filthy so much sooner and the Hepa filter costs at least $50.I will avoid all Bulk Filter filters.I recommend a set of 4 carbon filters plus the Hepa sold here on Amazon- www.amazon.com/gp/product/B00R9TXI5E?psc=1&redirect=true&ref_=oh_aui_search_detailpage by Vacuum Savings.

Thinner than the Whilpool filters I have received in the past. Made by a company called BULKFILTER. I guess they will be OK. They should not be advertised as Whilpool brand filters

Great Value
Great fit for the whirlpool 510. Has slots that match up to filter grill for alignment.
