The replacement cartridges work well with my BT400 filter. The carbon and foam blocks help keep the water clear and support good bacterial growth. I’ve used them for three months and the filter still performs strongly.

Easy to install and fits perfectly in my existing filter. The refillable design saves money over time. I noticed better water clarity after switching to these cartridges.

Great value for the price. The three-pack includes enough for multiple filter cycles. The foam block holds up well and doesn’t break easily during use.
