Marina (3 of Each) Slim Filter Carbon Plus Ceramic Cartridges and Zeolite Plus Ceramic Cartridges

Refills for the slim 20 filter, new set up and the 4 filters seem very efficient, fast water clearing and now maintaining a good water quality. Very satisfied. Nice to get an very quick and early delivery. Thanks.

Perfect!!!

Easy to install

Filters dont last long

Got this because it was supposed to be 3 of each type but was just 1 type and 6 of them

Easy to replace, works for 2 weeks then needs replacement. Works well

These go with the 3rd filter system I tried... FINALLY found something that works.. water so clean now... low maintenance!

This is a great product. I should have purchased this before any other products

Work well with intended filter. Look for the deals on these- many are overpriced listings.

Good Item
