Leonard Knox –
The filter works well and keeps the water clear. I’ve used it for about 50 days and noticed less odour and cleaner water. Easy to install and fits perfectly in my SF-240 filter.
Maria Howard –
Good filtration performance. The water looks clearer after a few weeks. I changed the cartridge after 55 days as recommended. No issues with fit or function.
Jacob Howard –
I’ve been using this cartridge for over a month and the tank water stays much cleaner. The wool traps debris well and the carbon helps reduce the smell.
