Passable product,
I bought this with the basic no frills (cheapest) Lasco 20 in box fan, clips really aren't snug but again this is a universal filter and not specifically designed for the fan I purchased, for a filter it does it's job,

    Works Great! Really impressed.
    Works great. Recommend to buy more than one and use the extra clips to hold in place and make extra holes or new holes to hold in place so you don't have to use any adhesive. It says it is washable which I haven't tested, gives no instructions as to wash by hand or machine wash and will attempt by machine. I originally bought 4, but I would rather just buy a new one than wash it.

      Good for box fan
      I got this box fan filter a month ago. Quality is great. But the clips included are not good to hold up with the fan. They cannot fit tight with the back panel. We need to put a tape or something to hold it up. If you perfectly Placed the filter, it does it’s job.

        Every year when I take my fans out of winter storage to get ready for those hot days of summer, I am appalled at the disgustingly dirty fan blades. I don't want my guests to view such a sight, so I unscrew the screws to take off one protective grill and proceed to clean the fan blades, then reassemble it all once again. What a pain! Then I discovered this product! What a great idea. At this point I can't access how well it works. I will update at the end of summer on effectiveness of this product, but anything has to be better than no protection, so I am hopeful that this will end my yearly cleaning ritual!

        I have a wood shop in my basement and dust is a big concern of mine. Not only from a cleanly point of view but also from a safety aspect. I got this product not to use for its intended purpose with a box fan, but instead modified it act as a pre-filter for a large homemade air cleaner I built. The way I built the unit the dust air goes through the motor and to limit the impact of dust in the unit, I am using this on the entry points. Before using it for my purpose, I tried it out with a box and it easily attached and I think would work quite well.

        The 20 IN. BOX FAN FILTER, fits like a glove, very, very easy installation too. The 20 inch box fans provides a precut center cut hole in case your fan has a center power cord. The fan filter has clips that insert in and clip into your fan grill, cant be any easier, The 20 inch fan filter is washable and should last for a long time. You can trim the filter for smaller fans, should keep fan blades cleaner and reduce allergens and pet dander.

        The filter works, but the attachments are useless. You have to get a friend to hold the edge of the filter to the fan (it won't lay flat after shipping, normal). I used clear tape and make a continuous seal all around the backside of my box fan to secure the filter on. The tape doesn't stick very well to the filter material, but it does well enough when all the tape is connected.

        The product is easy to use, but the clips that attach the filter to the fan pop off easily. Also, I suggest using the product on a high-velocity fan because the filter inhibits airflow. The great news is it keeps fan blades clean, and I noticed an improvement in my allergy symptoms. This product is worth it to improve air quality in the home.
