Product Description

Replacement filter pack for the Aquasana Countertop Water Filtration System: AQ-4000. Includes both filters needed for replacement (2-pack).

Use only genuine Aquasana replacements with your Aquasana products - untested replacements are not certified for performance capacity or contaminant removal. Replacements made easy - Simply remove the old cartridges and replace with new ones

The AQ-4000 Aquasana countertop water filter is the most economical way to get clean, crisp, healthy water for your family. Named one of Health Magazine's Healthiest Gadgets for 2011, our countertop drinking water filter offers Aquasana's unbeatable drinking water filtration technology in a convenient, portable package. There's no need for an extra hole in your sink to enjoy healthy, filtered water. Simply attach our diverter to your existing tap, and the countertop unit takes up just a small space on your counter. Water under pressure means better filtration. Some water filter systems strip out the healthy minerals leaving you with zero calcium, magnesium and potassium. The Aquasana water filtration system is uniquely designed to remove pollutants, reduce odor, and improve taste while preserving healthy minerals for optimum hydration.

Full system NSF certified to Standards 42, 53, 401, +P473 to remove 77 contaminants including lead, mercury, pesticides, pharmaceuticals, and more. Will not leach contaminants back into your water.

Replaces AQ-4025 in the following systems: AQ-4500, AQ-4501, AQ-4000, AQ-4050 and AQ-4055. Replaces AQ-4035 in the following systems: AQ-4601, AQ-4600, AQ-4000W, AQ-4000P, AQ-4000B, AQ-4601.55, AQ-4601.62, and AQ-4601.56

From the Manufacturer

The AQ-4035 is an updated replacement for the AQ-4025 The AQ-4035 cartridge set is a universal replacement for all Aquasana drinking water filters. The A and B replacement filters are guaranteed to be compatible with AQ-4000, AQ-4500, AQ-4501, AQ-4000W, AQ-4000P, AQ-4000B, AQ-4000N, AQ-4600 and AQ-4601. The AQ-4035 is our latest generation of replacement filters. We've spent the past 18 months redesigning and reformulating our filters to achieve our best filtration yet resulting in the new Aquasana AQ-4035 technology. The Aquasana AQ-4035 design and functionality are so unique, we've applied for a new patent. The drinking water filter set is the heart of all of our Aquasana drinking water systems. It features three distinct filter technologies: activated carbon, ion exchange and sub-micron filtration. Due to the unique manufacturing process, the Aquasana AQ-4035 filter is so densely packed with a sub-micron structure that water has to pass over 2.9 million square feet of contaminant grabbing media. That is how we achieve such high contaminant reduction rates. At the same time, the Aquasana filtration technology is selective, allowing naturally occurring healthy minerals to pass through minerals like calcium, potassium and magnesium. And that is why your water tastes so great.

Eh...
Size: 5 in
I had high hopes for these cause we have other spot brand toys that have last a long time. Unfortunately these just don't hold up to the test! My dogs had them broken in about 5 - 10 mins. They did smell good tho and my dogs went crazy over them before I ever got them out of the bag. Lol.

Smells too strong
Size: 5 in
My dog hates the way this thing smells. She tries to play with it, but the scent is too strong for her nose. I know it's the scent because she usually sniffs it two or three times in between trying to grab it with her mouth. She treats it like an explosive in her mouth and quickly moves away after spitting it out. She used to have a bone that looked similar to this (same material) that was unscented and she gnawed the hell out of it. My sister's pitbull spent the night and chewed that toy into bits, leaving my Yorkie mourning the loss of her once treasured bone. Please make an UNSCENTED version of this toy!!!!

If you were looking for a sign to buy this, here it is
Color: A) Small 2.5" Ball
If you are looking for a ball that can stand up next to a heavy, aggressive chewer.. this is a good choice. Our Pitbull literally destroyed any and every toy that she gets with the exception of one kind of kong ball. She tore through the kong Frisbees, any kind of squeaker toy, and the wobble wag giggle ball (she usually always ends up destroying these but it takes a few weeks. Today she beat her record and had her brand new ball destroyed within the first 30 minutes of us taking it out of the box). But, this ball she has not been able to destroy. I'd like to believe that the Kong ball she has and this ball are made of the same material. Because they are the only balls she can't ruin. And it's not because of a lack of trying. We have watched her sit there and chew with a side of her mouth for an hour or more, trying to make some kind of indention or tear in it and it just never happened. She loves to chew this thing, chase this thing, sleep with this thing. I most certainly recommend this ball. If it is I'ah proof then it is most certainly, 100% a durable ball and worth every penny

Chew King Supreme Chew Toy
Color: B) Medium 3" Ball
So far, freaking amazing. This ball is awesome. I have a 90 lb American Bulldog. Like other reviews. Lot of " indestructible balls" lasted minimum time. Not this one. She even took it to bed with her I bought the 3 inch ball, not the 4 inch ball. The 3 inch ball works amazingly for a large Dog. Yes the 4 inch would be better. So in my opinion, either ball would be fine. As others also said. This ball keeps a active Dog busy for hours. Love to play catch. Love frozen peanut butter in it. One last thing. The price is amazing. I don't see needing to buy another, unless it is lost, because this is made to last. We couldn't be happier.

Malinois proof
Color: B) Medium 3" Ball
So far this has held up great. My Malinois who has destroyed nearly every ball I’ve gotten her, this one has lasted over 3 weeks without a dent, compared to some that don’t even last a day lol. Although the medium size is a little too big for her liking she still plays with it. It’s very durable and I like the middle part for engagement as well. I would recommend if you have a dog who destroys every ball possible.
