Please provide me the gph rating of these filters

[Kobeclone]

Cascade 150-which I assume is 150 gph, but not sure
Whisper 20-40

I couldnt find the gph ratings. I know Whisper has changed their names of filters to like Whisper 20i and Whisper 40i.

I know these filters suck, but they are just laying around, so I could put them to use.

The "i" in 20i and 40i stands for internal, which is different from the whisper 20 which is a HOB filter. Which do you have?

 

[Kobeclone]

I have an old HOB filter.

Had no idea what the "i" stood for.

 

[Kobeclone]

I believe the whisper is 200 gph, correct?

 

[joey02]

the whisper is 210gph i believe

These rating may also be without media, so take them with a grain of salt.

Most filters are rated without media, baskets, or floss/foam. Basically just housing and pump. Some don't even include head pressure.
