Interest in AZOO Mingnon Cartridge?

I've been working on a little side project for the last week or so for my own personal use and figured I'd see if people on this forum would be interested in it as a product.

The cartridge is designed to increase the efficiency of the Azoo nano filter that is so popular lately. I had seen many people recommend throwing out the stock filter sponges for an oversized aquaclear 20 sponge, but knew this created it's own set of issues and I though I would try to address those. My cartridge allows for easy usage of a bio material and sponges by being easily removable. It's also forces all the water to pass through the filter material.

The stock filter sponges, as well as the common modification, allow much of the water to flow over the top, avoiding filtration. Because water will take the path of least resistance, flow towards the bottom of the filter box will be greatly reduced compared to the top. This is made worse by the common modification. My cartridge forces the water through all of the filtering material.

I'm currently running the cartridge with Eheim Substrat Pro and filter sponge.

Exactly my concern with many these filter designs. I'm all in, willing to test and contribute. Do you have somebody who can produce this cartridge?

I've just started my search for a source a few days ago but figured it would be wise to gauge community interest while I work on that.

I'd be curious to know what people think a good price would be. I have a figure in mind, but it will be heavily dependant on the order volume.

I just had some time fiddling around with my Mignon filter and also the aftermarket basket for the AquaClear filter.

Based on the InTank basket, your drawing might not be optimal, because in your flow diagram the water will be pushed through the main media from the top to the bottom. That won't work if that section is open on the top, or the water will just flow over again.

This is how this basket works and IMO the only correct flow:







That last water column in your drawing should be actually in-front of the media column.

IMO the basket should be designed like this:

The top of the basket is higher than the Mignon's pump side overflow so that the water can't flow over the top and skip the media. It does skip the media if it goes over the pump side overflow, but that can be controlled by the valve and how dense your media is.

Taking that into consideration, I don't believe there is enough room to have the water enter in from the back of the cartridge without creating major flow restrictions. The Mignon's pump seems overpowered for the rest of the filter. I've already gone through a couple revisions attempting to balance improved filter efficiency with creating too large of a flow restriction.

We'd have to get enough orders to get the pricing down to $15 or less per unit for it to be worth it to me. With that said I have 4 of these filters so you can sign me up for 4 once your testing process is done

Thanks for the input!

You got a point with those 2 protrusions, and running a Dremel inside might screw up the finish and is not for everybody.

I've got another idea. Why don't we design our own Mini Filter with proper flow? A basket inside an existing housing really is a half-assed design to begin with and having a basket manufactured or a housing is not that much of a difference.

I was just thinking that myself actually. I still think a good cartridge design aids in simplifying the manufacturing of a filter and cleaning (think canister filter). QC and marketing would also be much more complicated, but it would solve a lot of issues.

If we arrange a pre order / bulk order on a couple forums and get 50 people together we could contact one of those manufacturers in China. They sell these filters for $2:

https://www.alibaba.com/product-deta...87606.html?s=p

With tooling for a new mold we could get away with $15 or so each.

Or we throw some money in, start a new business, and get this rollin.

I was just looking at the same thing. Amazing what you can get from china. The most important part will be sourcing a pump that's quite enough from overseas. Could probably just get a sample though.

I wouldn't be surprised if those small Eheim pumps are made in China. Mine doesn't say made in Germany. If we could find the same manufacturer for the pump, that would be something. Good quality and very quiet for being made in China.
