Easy to use with my Whisper EX20
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.

Good disposal filters.
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

Great filters.
I change these filters less than other brands. They work well and are very sturdy. Not a lot b of charcoal dust come of these like the others do. The only downside is they have started shipping them in an envelope instead of a box. The charcoal gets broken up and vomes out of the filter wich renders them useless. PLEASE START SHIPPING IN A BOX

Lo mejor que puedes usar para tu acuario
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.

Buen producto a buen precio
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!!

Good Filters
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.
