Filtration performance with Waterdrop filtrete water filter 3US-AF01 replacement
Activated carbon filtration, usually in the form of high-performance carbon block filters, is the cornerstone of most under sink filtration system. Waterdrop 3US-AF01 replacement adopts the premium carbon materials from Sri Lankan coconut shell, which achieves a superior reduction performance. With our high-quality filter, it helps reduce chlorine, bad taste, odor, rust, sediment and more harmful elements, aiming to provide you fresh and healthy drinking water.
How does under sink water filter work?
Conventional under sink filter: It receives water from the under sink cold water pipe and water flows from a flexible plastic tube to the water filter. And the water will be delivered to the user through the filter's own special faucet, installed on top of the sink. The system is under constant pressure so that when the user opens the filter's faucet, the sink water will flow through the filter and out the faucet.
Simple under sink filter: In this arrangement the cold-water is diverted through the filter and filtered water is dispensed through the regular cold-water sink faucet. Besides, the hot water won’t be filtered. The simple under sink filter without a separate is becoming more popular and more practical with the advent of flexible rather than hard copper under sink piping. Flexible delivery pipes make the under sink water filter installation simple and affordable.

Good filters to substitute for the Original Filtrete filters.

These are effective replacements for 3US-PF01 Filtrete high capacity, under-sink filtration systems.
We have water with a heavy mineral content in this part of Jefferson City, MO. It means the water has a OK taste, but not really good, kind of a dusty flavor. So, since I drink a lot of water and make a lot of ice trays, I wanted something to make the experience better.

Hence, I installed the Filtrete system. I knew the filters were expensive, running at around $50 a pop, plus tax, but for good-tasting water, it was better than a pitcher or a Pur system, for my money. The long-life filter is designed to go six months, or over 1000 gallons of water. That's 10 Pur filters, by the way, or $140 worth of filters!

The water tastes good, and makes really good ice cubes. It also improves the flavor of meals that need water in cooking. The water flow is also better than a Pur faucet filter, due to the extra size and filtration capacity. Well worth the money.

These filters are easy to change, too. I have my unit installed just inside my right under-sink cabinet, against the side wall. This allows easy changes without blocking access or requiring that I get down on hands and knees to make changes. A simple ? twist to the left to unseat the filter, then pull it down and out. A few drops of water will drip, but cleanup is easy, no big messes. Then press the new filter onto the stem, and twist to the right to seat it. Run for 10 minutes to fill and flush the filter, then take a sticker and either place it on the filter, or a more visible place if desired.

I take and go six months into my phone calendar and set a reminder to change the filter six months later, and set it to Repeat every six months later. Very handy to do that!

Decent but not great

Works well but doesn't last as long as expected. 3 months at best instead of 6
