Okay so... I have a 20 gallon temporarily for my 4 inch turtle. I accidentally bought the smallest of this tetra filter, so I bought the medium sized one in it's place. I had only had the tank filled halfway anyway since my turtle was only 1.5 inches at this point. Mind you I didn't realize how fast they grow, and had no idea that Its recommended to have a filter that can filter 2 to 3x the tank size. So I decided to keep both filters in my tank. One on each side. Even though I still don't reach the recommended filter size, my water now almost filled to the top, stays absolutely clean. Turtles are pretty messy so I still have to do the weekly cleanings and all that extra stuff that apparently those who spend hundreds of dollars on filters still have to do as well. I don't know if this is some kind of luck thing, I don't know if maybe my turtle just isn't that dirty (yea right, I see him)... but I'm actually not looking forward to switching out my filter for the 'recommended' filter size, as these filters work so good. I love them.

They are both very quiet. Aside from the sound of the water falling back in.. I mean it sounds like a waterfall. Who doesn't want to hear a waterfall? I love it. This can also be prevented by raising the water level or lowering the filter itself. Basically the closer it is to the water, the quieter it is.

Such a simple device, yet so beautifully sufficient.

The little one stopped working at one point and I thought... welp there you go! Get what you pay for. But nope! Removed the base, pulled out the magnetic spring propeller and tube, cleaned it out and like magic it started right up as soon as I plugged it back in.

Love how easy it is to replace the filters. The filters themselves are great and definitely hold on to some dirtiness.

One thing I'll say is there is quite a bit of unused empty space. I now take advantage by adding some extra media, but I must say that these filters work great even without the extra.

Love this filter and would recommend above any other filter.

Filter works great. Had to replace the previous filter I had that was also a Tetra Whisper filter, my fault it broke down. It does have some noise. I would not put it in a place where you will sleep but it does work. I have it in the fish tank at the office. It's quiet enough where you can ignore it. It did not have any broken or missing pieces. I got the 10-30 filter, and it keeps my 40-gal tank clean. I clean it every1-2 weeks. I like that it has the option to put it inside the tank with the suction cups in case I want to put a full lid on my fish or keep hanging from the tank. I like to keep it hanging from the tank. Makes it easier for me to access it.

The filter is quiet and easy to use and clean. The filters fit easily. They do not last more than a couple years though.

This little filter packs a lot of power and it is fairly quiet. I had a larger filter that was supposed to be very quiet and it was not all that efficient and was also very loud. This was a fantastic purchase, a great value for my money. I have a 40 gallon tank. Set it up before a vacation and came back 4 days later to a crystal clear aquarium.

5.0 out of 5 stars Great value, super easy to clean.

This filter is as simple as can be, and that is not a bad thing.
The media is easily removed without having to remove the filter, and so maintenance is a cinch.
Being submersible also makes these very quiet, although the larger 20-40 gallon filter does make some noise and can it can also be awkward to place under a glass top tank due to its bulk.
I prefer the smaller ones also because they are so silent.
I use two 10-30i filters on each side of my 40 gallon tank rather than the somewhat larger 40i.
The 40i is also a bit flimsy as the handle can come loose because the snaps that hold it in place can fail, and so a little superglue can be helpful.
I still give the 40i 5 stars because despite some faults, it cost just $15 dollars!

1.0 out of 5 stars STINKY, NOISY, and WILDLY Inconsistent
Reviewed in the United States on March 9, 2021
FILTER #1 - A slightly smaller version of this filter came with the 5-gal 'Tetra Aquarium Starter Kit' we purchased. That one reeked of burnt plastic or solvent from the moment we unpacked it. Stinky odor persisted even after staging it in a 5-gal bucket for several days before fish. As others have reported, we also found this filter can be quite the noise maker. FILTER #1 - SMELLY, NOISY JUNK.

FILTER #2 - Concerned that stink and racket wouldn't be healthy for fish or us, bought another filter, reasoning that the cost of Starter Kit PLUS a new filter would be tolerable. Ordered what we thought was the same filter (but hopefully without stink and noise). What we received is the 5-10 Gallon Whisper Internal Power Filter, which turned out to be a slightly larger version of what we started with, but which still used the same size 'M' bio-bag. When we staged it in the bucket we were pleasantly surprised to find it was slightly more powerful than #1. But most importantly, IT DIDN'T REEK and IT WAS ALMOST COMPLETELY SILENT. This one turned out to be a keeper and is presently in the tank with fish. FILTER #2 - EXCELLENT.

FILTER #3 - Believing we had found a good filter, and wanting a spare, we ordered another 5-10 Gallon Whisper. It arrived with a hint of the same odor as #1, but we were hopeful that would 'just go away' after a few days of running in the bucket. But when we ran it in the bucket, we also noticed it was a bit noisier than #2. Then it quickly became a LOT noisier. But then, worst of all, we found evidence of mineral deposits from what must have been a very lengthy previous ownership (based on the LARGE amount of deposits). That's right, this thing was USED! FILTER #3 - STINKY, NOISY, USED GARBAGE

FILTER #4 - Allowing that an unscrupulous consumer might have returned a 'used' filter to Amazon as 'new', or something similar happened in the Tetra/Spectrum supply channel, we returned/exchanged for another 5-10 Gallon Whisper in hopes of receiving another unit like #2. Not a chance - #4 was as noisy as #s 1 & 3. Back to Amazon it goes. FILTER #4 - NOISY JUNK

So, we're done with Tetra/Spectrum filters. Based on our 25% success rate, I can't understand how these things could possibly have gotten the high ratings they have. There's no telling what's behind the problems we ran into, but the end result is a string of bad experiences with Tetra/Spectrum. No point in risking any more of our time or the well being of fish with this nonsense. We'll be looking elsewhere or going the DIY route - PLENTY of ideas on the web for fabricating what appear to be excellent performing filters from inexpensive and commonly available supplies, media and pumps.
