I don't know how it works, because I didn't get to use it. The box was wet on my porch, and inside the bottle of stability was cracked around the bottom edge and had leaked out. Very tired of getting wasted/damaged products from poor shipping practices by Amazon! Amazon should be refunding these things, but they don't seem to care.

Convenient to be able to have multiple replacements on hand at a much more reasonable price. Water seems to taste as good when compared to the LG brand filters I used previously.

This product needs a redesign, unless you like drinking warm water. Here is my experience. I filled the infuser with cut up strawberries, raspberries, blueberries and blackberries. I filled the product with cold water from my ice dispenser from my refrigerator. I knew I had to fill the water first before the ice so the infuser would fit after fruit filling. Now, keep in mind it is August. My air conditioning in my home is set at 74 degrees, I live in Virginia, it is humid here. My water was warm within 30 minutes. I am not a fan of drinking warm water in hot, humid weather. After adding the crushed ice to the product it was difficult make it fit in around the infuser. I managed to get the product half full with ice. Once I finished the drinking the (fruit) flavored water, I hand washed the product and put it in a box for donation. This product is not for me. I am looking for a product that can be fruit infused and keep the water cold without all the fruit floating around in the drinking container. Someone out there will design this product, eventually. My search continues...
