Great Filters for the price but need to be changed weekly or at the very latest every two weeks!
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!

Good value and fit perfectly
These worked great with my filter to help keep my tank clean. Easy to insert and fit just like the name brand version.

Got packages already
Amazon Customer –
Works great and crystal clear water. Only last about a week – a week and a half
Works excellently, have to say they can get clogged up fairly quick tho. Longest they last is about a week before my overflow starts spitting out extra water. With a quick rinse they last a few more days. Worth the money tho since theyâre cheap.

Good filter for a good price.
Good carbon filters. Thick flossing material and plenty of carbon.
D DeLoach –
Highly Recommended
This product is amazing! I highly recommend it! The suction feature sticks well and doesn’t pop off. The air vent feature is nice because it allows you to adjust it to fit any vent. We will be able to use it in both of our vehicles. My husband was impressed, and he is very picky. Do yourself a favor and order this, you won’t be disappointed.

Good quality for price
Rocio –
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
Janine Cunningham –
I get them all the time. Ya, they work just fine.
Fers –
El filtro dura mucho menos que el original, asi que terminas usando mas filtros.
