### ⭐⭐⭐⭐ 







  
  
    Good, but you will need to work a little bit to make it fit your fan well
  

*by H***Y on Reviewed in the United States on June 11, 2020*

This is a good thing to have if your box fan is on a window.  Filtering is good for this type of filter at this price.  There is some loss of airflow, but not so much as to matter in my situation.  Washing removed enough dirt from the filter to satisfy me and I prefer a cleanable filter that will last to a disposable one.Overall I am happy with the way this works.The only reason that it is not 5 stars is that it is kind of a pain to get the filter to stay on the fan consistently using the provided clips.  The clips are generic and fit the middle range of potential fans.  In the case of my two (different brand) box fans neither fit particularly well.  In both cases the filter just hung loosely and it would not stay put when the fan was off and suction ceased.  At least one clip came off any time I moved the fan.  Fortunately this was solvable.  I punched new holes in the filter at exactly the locations needed to clip onto the larger parts of the plastic fan cover.  That worked well enough to make me happy.  But I also had some cable management clips that had adhesive backs and a loop to hold cords.  Placed right in seven places (four corners, both sides middle, and top middle), these hold the filter in place securely and with no slips.  Most people would just have been happy with the new holes and better clip position.For the amount of crud it catches, it is worth the effort.  The price is good for what you get.

    Works fine even though the clips are loose
  

*by M***M on Reviewed in the United States on October 22, 2019*

My daughter is allergic to the dust and dander in this big drafty house. I can’t afford an actual air cleaner, especially for every room, but I have fans, and they always get full of hair and dust. This filter is a great cheap alternative, for filtering out some of that.The clips are loose, they don’t hold onto the screen. Even though it looks like the filter was made for this fan. It comes with holes you can push out to put the cord through and reach the knob, for those fans with the stuff on the back.When you turn on the fan it holds the filter in place anyway. It’s not perfect, not meant to filter 100% of the air, but it’s really awesome for pet owners because all that hair will stay on the filter. And then, it’s washable! And air dry. I just got it so I don’t know yet how well it washes. But I’m good at laundry so I’m not worried.I was worried about it restricting the air flow but it’s fine right now. I imagine once it gets dirty it might restrict the flow, just like any filter. That’s when you wash it.

    Nice Option For Box Fans
  

*by B***C on Reviewed in the United States on February 15, 2020*

This filter fits my box fan perfectly.  The clips that hold the filter to the fan work fine.  They are not tight, but really are only there to keep the filter from falling when the fan is off.  When the fan is turned on they snug up to the grill just fine.  There is a trade off:  The filter does have a bigger than desired impact on air flow, but if you have allergies and/or pets it's good to have.  I have 2 cats so keeping pet hair and dander from flying everywhere was my main reason for purchase.  If you are careful when cleaning/washing they keep their shape.
