how is the carbon activated?
There a few different ways to activated carbon but the most common is thermal decomposition. Its baked in a furnace at high heat with a controlled atmosphere, the absence of oxygen.

Can you use the bio_bag filter in a 10gallion tank as replacement
For the carbon type filter.
That would depend on what filter you own, but if you bought it as a Tetra kit, then yes, you would be albe to do so.

Can I just purchase the bags and charcoal poaches, or just the bags not the Charcoal, for the 30-60 or large size. Not the plastic Assembly part. I already have bunches of them. I think it is just a waste to keep throwing away plastic. And if so where?
Unfortunately, no, they do not come with out the frame. You might turn them into a recycling plant or see if another hobbyist in the area can use them. Check for an aquarium society in your area.

would the XL catridge work for a secondnature whisper power filter 5
We have an ancient but still functional whisper power 5. My understanding is that it has been discontinued
Correct, it is discontinued, and you are very lucky to still have one. I have one as well. Love those! And yes, the XL is the size that you need. We do still make those cartridges in a limited amount as an unassembled 4 pack only.

Bio bag in Whisper EX filter?
We bought a second hand tank with Whisper EX30 filter. Along with set, we received a box of carbon filters to fit the EX30, AND a box of unassembled Bio Bags. Can the Bio Bags be used in the Whisper EX30 filter?
No, because they are square, not rounded, they do not fit very well.

what it the size of the X Large
I have a whisper power 4 filter. I need a new cartridge.
6.5" x 9.25"

Please clearly indicate the size of the small, medium, and larger filters
Please clearly indicate the size of the small, medium, and large filters in inches (eg 4.5 x 6.25 in or 4 x 6 in) so that we regular users know what size we need. On the package and on the web site. Sm, Med and Lg is relatively meaning less. Some of us began using the filters when you only had one size.
I don't recall there ever being a single size, and I sold Whisper products back in the mid-1980s when I worked in a pet store. At that time there was Medium, Large, and Extra Large. I suppose back in the 1970s, they may have had one filter and one cartridge as filtration was pretty new back then, in general. We've never given dimensions to them but have always tried to make the packaging and sales information as clear as possible with color coding, tags on filters, etc. I have forwarded your request to marketing.

yes I'm looking for replacement parts for tetra tech pf150
Those are no longer available, unfortunately. You do have a lifetime warranty on the filter however, so if you ship it back, it will be replaced with a Penguin 150, the closest we have to that model. Please include your information inside your package.

I'm looking for a Whisper Bio-Bag that is 3 X 6 inches in size
I have a turtle tank with a climbing rock that contains the water pump and two carbon filters. I've been using the 5 X 6 inch size but it hasn't been ideal (too wide to fit in the slots provided for filters). So, I've been modifying the frame by cutting off 1/3rd of the width - the first section; and folding the filter media over to fit (stapling the excess).
Is the Whisper Bio-Bag available in a 3 X 6 inch size?
That system takes the Whisper Bio Bag Medium size. It is readily available through fish stores as well as online.
