These filters work perfectly with my Tetra water filter. I have the 20 gallon Whisper EX for my fish tank. This filter fits perfect with it, and I can probably go about 1 month between filter changes. I don't notice any issues with the filters either. They fit perfectly in the frame, and a minimum amount of algae grown happens. When it's time to replace them, they pop right back out and go into the trash. The filters are able to hold up, and I've never had any issues with degradation. I have been using them for about 3 years now with no issues at all.

The filters fit exactly as noted. They really keep the tank clean and sparkling.

Good filters not really sturdy to even rinse snd reuse, but they serve the purpose. I like to put a used filter with a new one so I don’t crash my cycle in the aquarium I just have to soak these in water together instead of putting it in the compartment together. It’s ok though

These filters are incredible, I slice the top part on the coarser floss side to add my own mix of carbon & ammonia remover and have them going in my 75 gal tank. Keeps my water clean, clear and under control. These things are work horses. Love how useful they are. Edited 11/29/16: I was able to keep a set of these running (with monthly rinsing out in tank water, and monthly carbon refill) up to 5 months before it started to really get clogged and slow the water flow coming out the filter. I might change out sooner at 4 month mark. But still, it went a long ways! I also have been running Purigen in this filter. Like I said before, I slice the top of the filter, dump out the loose carbon and insert the 100mL pouch--It fits perfectly inside--And, for the past 2 months, my tank has a pristine blue clarity to the water like never before seen. Great way to hotrod the filter.

These filters were great. I tried the generic ones once and I didn’t like the results. I’ll always buy these now. They’re the best they keep my fish tank clean and my water blue. I know the fish appreciated.

Serves the purpose and works great with the Tetra Whisper pump

Cling the tank very well noise level is very low

Like the fit and quality

Yo hacía mis propios filtros con carbon activado que me recomendarion en la tienda los profesionales, pero no daban el mejor resultado. Decidí comprar los repuestos originales para asegurarme de tener lo mejor para mis peces y desde el primer día noté la diferencia, funcionan excelente, limpian muy bien el agua y la mantienen por más tiempo en excelentes condiciones. Duran bastante tiempo sin tener que cambiarlos. Acabo de cambiar el primer filtro después de 1 mes y medio, y creo que pude haberlo dejado los 2 meses sin problema, pues no estaba tan saturado de deshechos. Los recomiendo ampliamente.

Un paquete de filtros a un precio excelente. Más barato que en tiendas de mascotas!! Duran bastante y se pueden rehusar dos o tres veces lavándolos! Tengo el filtro para pecera de 80 litros y la matiene muy limpia con estos repuestos!!

I've been using these filters for my tank since for about 15 years now. They work great. I believe the packagings suggests changing the filters out every 3 months but I can normally keep mine going for about 5-6 months.

En general, es buen producto, duradero y cumple su función.
