16 Pack Rite-Size C Filter Cartridges Compatible with MarineLand Filters

These filters fit perfectly and do the job just fine. Easy to change and they keep the tank clean and clear. Good quality and a great deal for the price. I’ve bought them more than once and would definitely buy again. 👍🐠

These fit perfectly in my Marineland Penguin 350 filter system. Great price and super convenient as my local pet store rarely has size C in stock. I will continue to purchase these for now on. Quality appears to be just as good as Marineland.

Once the price of the Rite Size C filters went through the roof, we started looking for a cheaper alternative since the cost adds up quickly with several fish tanks. We bought the 30+ pack of these filters to save money and have a stock on hand in case the price went up again. While the OEM Rite size C filters have just a little more carbon and a little better blue filter floss on them, these are almost just as good! For what you pay for these compared though, these are the best "knock off" we have found so far for the price. These filters keep the water clear for at least a week, which is where a little more carbon would probably make a slight difference in how often you need to change the filters. While these are not OEM, these filters fit my hang on the back Penguin Rite Size C water filtration devices perfectly! The filters are easy to use and install. The filters function as they should and catch quite a bit of debris, including some of the smaller particles. The water noise level running through these filters is low and these are almost as good as the OEM filters but at a much cheaper price point. I paid around $1.86 for each of these while the OEM was just over $3 each at the time I bought these filters. The filters came in a large brown box with each filter being individually wrapped in plastic with breathing holes on each plastic bag surrounding the filters. I have been using these filters for about 6 months now and am very happy to be saving money while keeping my fish happy and healthy with clean water!

Fit well and did a good job filtering my goldfish tank but seemed a little light on filtration ingredient inside the filter. High quality outer shell and plastic filter screen. I would definitely purchase again if on sale as they were a good price for the quantity but didn't last as long as others with more carbon.

Great value . Well made. Fits marine filter well..

Works as intended. You can rinse and reuse a few times to help save money.

Wonderfully made fish filters.They've been the same for decades.There's no reason to change perfection in a design nicely done for decades.A company you can trust

GOOD FILTERS work well and price is reasonable.

Noticed a big difference in cleaning performance as well as water flow as soon as I installed 1 of these filters. I have a Marina 275 (40Gal Tank) and this was able to filter water flow 3/4 volume turned up without overflowing. Highly recommend.

Los filtros son ligeramente más delgados que el de la marca original pero dado que solo son para 1 mes de uso y volver a cambiarlos para mantener el acuario en óptimas condiciones están super bien, limpian igual y traen la misma cantidad de carbón, no se batalla nada para iniciar solo con un enjuague para q se limpie bien el carbón y listo, los probé y te dan el mismo resultado q la marca original pero a un super precio, venia toda la caja rota pero al final los filtros están en buen estado, recomiendo su uso

Fits perfectly, glad I didn’t have to leave the house to go get it

El filtro dura mucho menos que el original, asi que terminas usando mas filtros.

Perfect!!! They keep tank clean.
