Aquaboon5 Micron 10 x 2.5 Granular Activated Carbon Water Filter Cartridge GAC Water Filter Replacement Compatible with AP117, GAC-10, GAC1, 6 Pack

Installed the 1st one 2 weeks ago. Seems to be working well. Saved a lot of money buying these as was paying over $7 each before. This product seems bulkier than the ones I used to buy and the quality of construction seems better. Will update if the experience changes but, so far, GREAT purchase. We are on rainwater catchment and have a bit of acid rain, esp. since our volcano became more active. The water quality change was apparent and the charcoal filters improved it drastically. We are now adding baking soda to our catchment tank to reduce the acidity and I am hopeful that the carbon filter will effectively reduce any flavor change that this causes.

It will not fit inside filter GAC1 canister and it is NOT returnable.

The filter came quickly and will do what I need it to do for the system.

Recommended by a plumber. 5 micron better filtration. My water is bad well water. Last 3 times longer than lesser styles

Water tasting better after running it for a while. Smell/odor almost gone.

Works absolutely great. There is no taste or smell with our well water.

This filter clears most of the chlorines from our heavily chlorinated city water, but not all of it. Using two or more on a line will reduce your pressure to the point of not being able to flush your toilet and wash your hands.

These filters last no more than 4 days. The 2 pack 5-micron filters I get from Wal-Mart last 10 days on average. They are only $8.99.
