Why is there a SQUARE filter?

I assumed it was just to double up on the filters. I put the square one in first and then the round one holds it in place.

That's a puzzle to me, too. I use them both putting the square one in first, figuring the round one seals the lid to keep the odor inside the bucket. And, I'm guessing here... maybe you need both or maybe some buckets have a different configuration.(though I don't think so) I do have the larger compost bucket. Using both filters together works in my kitchen.

There are different types and sizes of compost bins. My round one came with a square filter to begin with....why I don't know. If you order the square one, be sure to measure the opening to make sure it covers the opening.

I have no idea why it is there, not like it fits anywhere else, what I did is take the square one and put it above the round one which is held in by friction.

Our picture doesn't have a square one...humm.....not sure but the round one is the one you would get when ordering this item from us, Farm & Home Supply Center.

This lens has no filter thread. It's a fish-eye, and the front lens element protrudes to an extent that precludes the use of filters. You expect this in a fish-eye though.

No the 58mm is for use on round filters. Not sure what you would need for square filters.

Yes Thomas, you should definitely use filters to filter out other sources (some known and unknown) of interference.

I have line filters because I have DSL. Not being terribly technologically talented, not sure if this is what you're asking.

The previous answer is exactly right. Just get your fingers to grip the filter and pinch it toward the middle. It will bend and come right out. The second filter (closest to the top of the lid) will be easy to remove....grab, pull through the same hole you used to remove the square filter.

It's kinda "compressable", so has plastic panels like you see on the sides. Probably best if you need a more flat filter rather than a cone type.

The "Square" Profile does refer to a more rectangular shape, more squared off. But this is in contrast to the rounded "Aero" profile, which is more airfoil shaped.

Believe there is a notch somewhere along the rim of the filter to facilitate removal. Also mine came with double filter. But I use only one. Seems easy to remove,

It has a mesh filter but a tiny amount of ground filters through, in mine at least.

The square filters are in the top three rows. They fit slide into one of the frames in the lower right. The frames slide onto the lens adapters in the lower left. You use the the appropriate size lens adapter. You don't need anything else. (You can stack filters in the frames on the lower right. It will be obvious if you get them). I like the filter set.

I believe they are called come shape filters. However it come with a reusable filter basket that works great...

This filter is made with 2 screens instead of 1 like most other filters. It works well.

Square. There is a heavier duty model called the e4. Both are excellent. Get whichever your application requires.

HI, due to the angle of the lens if you don't use a thin filter it will vignette around the edges.

Cone filters. But I dont use them. The mesh filter works great for me. When it wears out I will switch to the # 4 paper filters.
