My faucet does not have a screw/unscrew capability and is installed with a pullout hose/faucet. Will this still be compatible? Do you have other attachments?

Asked by AndyM November 30, 2020

Answer

Hello Andy, We appreciate your question. The only faucets the AQ-4000 water filtration system will not be compatible with are the 2-in-1 faucets that have a detachable sprayer at the faucet opening. The AQ-4000 will fit most standard faucets and also comes with two adapters. Unfortuatnely, we do not carry any other attachments that will fit a 2-in-1 faucet. -Aquasana

Can you get adapters for different tap attachments? Our tap doesn’t screw from the inside, but the outside. And do you ship to NZ?  Thanks

To my knowledge, the unit comes with an adaptor for both inside and outside threads on your faucet.

Can you directly drink the water that's filtered from AQ-4000 or do we still need to boil the filtered water?

Was skeptical, pleasantly surprised
This was incredibly easy to install and it’s easy to use. I love having filtered water at my fingertips, and we use it several times a day! This is perfect for apartment living. I did use a rubber band to loosely hold the tubing out of the way, but it doesn’t interfere in anything.
by CarrieJ
Great filter if you don't have much space
Finally have a piece of mind that contaminants have been reduced and that 'drink more water' is actually going to be better for my health!
by Rousanna
It does what you want it to do
I have been a customer for at least 4 years, and my parents even longer. I must say, I truly like the job this filtration system does. And I have attached a picture to prove it. The filter on the right is the first filter the water enters through. Then it goes into the chamber with the filter on the left. This amazes me, and has made me even more of a loyal customer.

Its wonderful. Clean water right from the tap. The filters are a total pain to change. I think everyone just buys a new one. I've had it for years and I still can't easily change filters.
by David The Water Drinker
simple and effective
I'm conscious about the choices I make when it comes to what I put in my body. I really like the simple and effective use of this countertop setup. It was easy to install taking anywhere from 5-15 min. The only thing I'd like to know or have is mineralization and a water structurer.
by outdoors enthusiast
works as advertised
Setup was simple with easy to follow instructions. I had it out of the box and operational in less than 5 minutes. Now I can make my coffee using tap water and it tastes great. The unit takes up very little counter space and doesn't get in the way. Water flow is reduced when using it but that's to be expected and there are no leaks

Installs Fast, Filters up to 450 gallons, Chromed Metal Faucet Fixture
The water filter by Aquasana is great in applications where you want your tap water filtered without installing a large filtration system onto your entire house water supply. Out of the box you'll get the silver plastic filter container with filters pre-installed, the chrome metal hose/faucet attachment, the hose assembly and an assortment of adapters and washers for different sinks. The parts count is low, and installation takes less than 20 minutes including flushing the filter once it's hooked up. NOTE: This filter will NOT work with the type of gooseneck faucets where the entire faucet head pulls off as a sprayer. It's important to know that before you buy it. You insert the color coded hoses into the bottom of the filter housing, then unscrew the faucet strainer and screw on the new faucet adapter/filter lines. If you can attach a hose to your faucet, you can install this filter. No plumbing experience, special parts or plumbing tools are needed. Once installed you have to flush the filter for ten minutes and then you're ready to use it for drinking water. You can only use cold water with this filter. Hot water will ruin the filters. Press the tab on the adapter and turn on the cold water. It flows at about 1/2 gallon per minute with the faucet opened all the way. It's completely silent, no odds sounds like some smaller size filters as the water is pushed through. It doesn't take long to fill a pitcher. Once the container or glass is full, shut off the water and the filter valve automatically closes for you, letting you use the regular faucet again. The filtered water is crystal clear and completely odor free. Just like water should be. Replacement filters can be found easily by searching the model number of the filter you have.

Easy to install. But it seems to have a continual drip. Overall an inexpensive basic counter filter for my travel trailer.

Disappointing
I was hoping I could stop shlepping gallons of reverse osmosis water from the store, especially during covid lockdown, but I am not satisfied with the taste of the water. I have countertop aquasana filtration and found there was no change in total dissolved solids in tap water after filtration. I must say our tap water here in suburban Minneapolis is truly awful and virtually everyone buys drinking water. I was used to reverse osmosis drinking water and prefer the taste. But I am sold on the Aquasana water being cleaner and better for you and continue to use it for making tea/coffee, rice or pasta, rinsing berries and making lemonade. But for a straight glass of water, I'm still shelpping.

Works great!
I've had this filter for about one year now. I've had no issues with leaking and my water is so crispy fresh, I can't believe it. And NYC is supposed to have the cleanest water but when I compare the non-filtered to the filtered, the Aquasana is clear and doesn't have the cloudy appearance nor the little white particles that the tap water has floating in it. I have a suggestion for the people who are hesitant in purchasing this because some folks said it leaks. My friend has this unit as well and is always moving the unit around which loosens the the tubing which makes her unit leak. I leave mine in the same place, out of the way from the day to day, and I have not had any issues with this leaking and it's been one year. I move it to clean the counter so you can move it around, just be gentle.
