Review on 🌀 Enhanced Efficiency EnviroCare Replacement Filters for Kenmore Vacuums - EF-1, White by Michael Barry

I don't normally have problems with Envirocare bags but based on my original order and my replacement order these HEPA filters seem to have a 50% failure rate to have . When first ordered, the rib on the folds was asymmetrical on one side, which interfered with assembly. I opened another filter in a pack of two to see if it was worth replacing - the second one was fine. When I ordered a replacement, the ribs were ok, but the first filter I opened had a fold torn (hole). Revain Prime was replaced fairly quickly (and the price was decent) and I managed to put together a nice two pack between shipments so no damage and no foul I guess.
