Seem to work well.

Great Price Speedy Delivery

Keeps dust to a minimum

Looks like a quality product. Fits over air filter very well. Easy to install

As expected and far cheaper than buying in retail store.

I bought our lawnmower brand new, and when I opened up the air filter box, I found a standard pleated paper filter and nothing more....no foam pre-filter band. OK, fine....it's just a lawnmower, so maybe a pre-filter is not used. Then, when I searched the replacement part number to replace that used pleated paper filter, I found plenty of options of also purchasing the matching foam pre-filter band. I know from experience that the foam pre-filter band is an advantage to keeping the pleated filter underneath it clean for longevity of use. These AutoEC pre-filter bands are very inexpensive and provide a valuable service.

Mowers run great now

They flex well and fit nicely around my 593260 air filter and I can tap clean them and use my finger to lightly brush them off. I could wash them in water of course and let them dry if I feel I need to in the future. Well made. Worth it as the paper filter element is still like new after about 6 mows now.
