How much do they cost?

Counter top distillers range in price from $380 to $500, larger automatic units start at about $1700 and increase from there depending on the choice of storage capacity and accessories.

What do you do about replacing the minerals removed?

The minerals that exist in tap water are of an inorganic form and are not beneficial to your system. Minerals that your body needs are in an organic form that you would get from your foods and fresh vegetables.

How much electricity does it use?

The distillers use about 3.2 kilowatts per gallon. Based on the national average electrical cost of 8.48 cents per kilowatt hour, this equates to approximately 28 cents per gallon.

How big is it… will it fit on my counter?

The countertop distillers are about the size of a large coffee maker. They will easily fit on a standard counter. The dimensions are approximately 10″ by 16″ by 15″ tall when in operation.

Is it OK to use softened water, since it says not to use salt water?

Yes, the small amount of salt remaining in softened water will not hurt your distiller, in fact using your softened water will make it easier to clean your distiller, because most of the hard minerals have been removed by the softener.

What is the pH of distilled water?

Water produced through steam distillation in combination with carbon filtration is some of the purest water available. Theoretically, pure water should have a neutral pH reading (7.0). But the very purity that should make steam distilled water neutral also makes it very sensitive to the addition of other substances. The near absence of dissolved solids means the smallest amount of any substance will dramatically change the pH of distilled water.

How long do they last…and what is the warranty?

Our distillers typically provide three to five years of uninterrupted, trouble-free service. These units are warrantied against defects in materials and workmanship for a period of one year from date of purchase.

What materials are the collectors made of… and are they BPA-free?

The material used in the Model 4000 collector is borosilicate glass and is BPA free. The material used for our Model 8800 is polypropylene. The collector/dispenser bottle of the 9000 is Tritan. Both of these materials are BPA-free. Our 7000 series is stainless steel and BPA-free, as well.

Why aren’t all of your collectors made of glass?

Borosilicate glass is not as readily available as it used to be and the unique shapes of our collectors make it more difficult and very expensive to obtain molds, etc., for our small quantities. It also takes several years to design, test, and get approval for new containers. And borosilicate glass, being very fragile, does not ship well, and is not as easy to handle.

Does it remove everthing… minerals, vitamins, heavy metals, pharmaceuticals?

Tap water is brought to a boil. Steam rises and enters the condensing coil. Cool air is passed across the condenser, converting steam back to pure distilled water. The distilled water then percolates through the coconut shell carbon filter and is collected. The process of steam distillation combined with carbon post filtration effectively removes at least 99% of impurities.

Why do I need to use carbon filters… doesn’t distillation remove everthing? Will it work without the filter?

Yes, it will work without the filter, but the volatile organic compounds found in the water can cause a bad taste, and could be carcinogenic. The post carbon filter will remove the VOC’s from the water and eliminate the bad taste.

How much water does it make?

One gallon of 100% steam distilled water is produced in 4 to 4.5 hours, up to 6 gallons in 24 hours.

How long does it take?

One gallon of 100% steam distilled water is produced in 4 to 4.5 hours.

How much does it weigh?

Without water, the 8800 weighs 14 lbs, the 9000 and the 4000 each weigh 10 lbs. The stainless steel 7000 series as follows: countertop 7000/3-gallon weighs 30 lbs., floor-standing 7000/8-gallon weighs 37 lbs., and 7000/12-gallon weighs 44 lbs.

What materials are the distillers made from… are they BPA-free?

All wetted materials are FDA rated. Boilers are 304 grade stainless steel (4000 and 8800) or a combination of stainless and high temperature polypropylene (9000). Condensing coils are 304 grade stainless steel.

What is a “like new” demo?

A ‘like new” demo unit has been tried by one of our customers and returned to us under our 100 day risk free money back guarantee. The distillers are fully tested, inspected, repackaged, and carry the same warranty and money back guarantee as a new unit.

What maintenance is involved?

For optimum performance, you should rinse the boiler after every distillation cycle to remove any loose residue. As deposits build up, use an approved cleaner such as Kleenwise, for monthly cleaning—this frequency varies depending on the quality and hardness of the tap water and frequency of use. The carbon post filter cup should be discarded and replaced every two months or after 60-80 gallons of water processed(whichever comes first), or when undesirable taste/odor is detected.

Shouldn’t I clean it every day… do I have to use Kleenwise?

The boiler should be cleaned about once a month. This varies depending on the quality and hardness of the tap water and frequency of use. Rinse the boiler after every distillation cycle with warm tap water to remove any loose residue. You may use our Kleenwise or a 1 to 1 ratio of distilled white vinegar mixed with water.

What if the distiller breaks down… how do I get it fixed?

If you have repair/technical questions about any of our distillers, please contact us via Email at service@waterwise.com or give us a call at 800-874-9028 Mon-Fri 9-5 ET and ask to speak to one of our onsite technicians.

Why is distilled water better than alkalized water?

Distilled water is the purest form of water available to the average consumer. Your body needs pure water to work at its optimum performance removing waste. Alkalized water has to have contaminants in the water to have the capacity to be alkalized. Water with pH above 7 has a tendency to make your system create more acidic conditions to offset the alkaline water, therefore it actually works in reverse to some information being circulated.

What is the micron size of the prefilter?

The micron size of our prefilter is 0.5 microns.

Why is carbon good as post filter for distiller, but not for shower filter?

Carbon works very well to remove VOC’s as a post carbon filter because the flow rate is greatly reduced (1 gallon in 4 to 4.5 hours), thus the contact time is much greater, which is necessary for the adsorption of the contaminants. In a shower filter, the flow rate is at least 2 to 2.5 gallons per minute, which has a tendency in hot water to actually remove the stored materials from the carbon instead of removing them from the water.

Why do you charge more than your dealers?

Our authorized dealers are allowed to set their own prices and specials. Sometimes their specials are better than ours and we do not compete with dealer prices.

If I don’t like it, can I return it?

Waterwise offers all of its direct customers a 100 day, 100%, risk free, money back guarantee. If at any time during that period you decide to return it, call us and we will provide you with a prepaid return label to ship your products back at no cost to you.

  1. Sandra Tompkins

    I purchased the 4000 in June of 2022. The customer service is amazing!!! I know the name of the person that took my calls about any concerns I had because unlike a lot of customer service, they actually have knowledgeable people to talk to about the product and not only that, the turnover must be low because I was able to talk to the same person several times. He not only answered my calls yet he answered my questions and he absolutely fixed any issues or concerns I had immediately. It was so nice to get a live person and not a recording and talking to a machine or pressing 50 buttons to get to talk to someone. It was so amazing that not only could I talk to a live person yet THEY ALSO WERE KNOWLEDGEABLE ABOUT THEIR PRODUCT and could offer solutions that worked. It made me so happy to have purchased this product and it works and I have had this product for a number of years now. If you are looking for distilled water, buy this. It works and they are concerned about the quality of the water you are drinking and I’m happy that the water is touching as little plastic as possible. My hands had started feeling achy yet a couple of months of drinking distilled water from this Water Wise machine and all the pain is gone!! Thank you!!!!

  2. Christina Duncan

    I SO LOVE this distiller which I have had for about four years now. My doctor even commented on looking at urine and blood test results, “Boy, your kidneys are working well!” which speaks to the purity of the water I’m drinking and not drinking down every day the crusty minerals left behind from distillation! One TIP in cleaning this specific unit: I used to clean it almost daily using vinegar (use the heavy-duty cleaner Waterwise sells if you clean only weekly), and would pick it up and hold it under the kitchen faucet, which was tiring. So, I bought a screw-on faucet head that swivels in a wide circle (after it loosens up; from Home Depot and elsewhere), and now cleaning the unit is a breeze. Another TIP: To avoid damaging the cord, be careful not to push the unit up against a wall, like I did for three years! The covering cracked (it still works AND you CAN replace the cord), but the point is you can avoid that just by being careful to angle the unit when you push it back on the counter so that the cord stays pretty straight where it comes out of the unit.

  3. Megumi Knauff

    I bought this system last year, It is great product. Water Taste is very smooth with their filter and machine is quite stable and good quality material they use. My husband love this one too!

  4. Alberto Rodriguez

    Excellent distiller and the water is clean tasting and refreshing compared to filtered water. Easy to set up and use plus cleaning is a breeze. This is a must have if you value your water intake and health. I purchased mine through an online retailer and I am very satisfied with my purchase…thank you WaterWise!

  5. Betty Nelson

    I bought the 4000 after my other one died. I LOVE this model. It makes water in about 4 hours. The glass carafe is a plus. I like it much better than the plastic pitchers. I use water and white vinegar to clean since I’m on Guantanamo Bay Cuba. The water here is reverse osmosis and has a heavy cholrine smell. I used a water analysis and it tested better than bottled water. I highly recommend waterwise. I also use there shower purifiers and air purifiers.

  6. Gary Shook

    Great product. Easy to operate. Live in the country and have well water with a top model water softner. Water tastes great. No odors or taste of salt. In fact, water does not have a taste at all. I am on a low sodium diet and this product is perfect for me and my wife. We have it on the counter in the kitchen.

  7. Robin Neighbors

    I bought my 4000 model in 2005 after a friend spent years recommending it. After the first time I distilled a gallon of city water I’ve not had any problem being motivated to continuing using it. My city water comes out of the Ohio River. Our water dept. does a great job with what they have to work with cleaning this river water. However, when you remove the water what is left behind will gag you. After each cycle is left behind a very small amount of liquid which I once put in a small container and showed people. I asked “what do you think this is? Responses weren’t very flattering.
    I once had to replace the wiring harness. I easily did it myself for under $40. Very easy. If you aren’t tech savvy just sent your machine back to them and their technical support people will make your machine like new for a fraction of the price of a new one.
    If something went wrong with my machine and couldn’t be repaired I’d buy another machine immediately.
    I’d give this product 6 stars if another star were available.

  8. Ron

    I purchased a water wise distiller about 4 years ago. When I purchased it the advertiments said its longevity far exceeded that of a sears model. I was skeptical, but chose to try it because sears no longer made them. I want everyone to know I am completely satisfied with this product and I am thinking of buying another in the near future. Thank you for such a superior product in this world of throw away items!

  9. Claudette D.

    I have been drinking only distilled water processed by the Waterwise 4000 for 2 months now. I use it for drinking for making coffee and tea and for cooking and making soup. I bought it when I read that distilled water could help with joint pain. Before this I had to use crutches every morning when I got out of bed because of pain and stiffness in my joints, especially my ankles. I do not need the crutches now because the stiffness and pain have become minimal. On a lighter note, the flavor of my food is different as it no longer is covered up by the taste of tap or just filtered water. I am grateful for the Waterwise 4000!

  10. Beverly H.

    I was scared when my 90 year old mother purchased a water distiller for me, after I told her I had been looking at them. I needed stainless and glass. The ones I looked at ran about $600.00. Then she said she purchased one at about half the price. I just knew it had to be some plastic, cheap thing. I was pleasantly surprised when this high quality one arrived! I couldn’t have done better. Stainless, glass, easy to interpret instructions,…..The list goes on. I run app. 2 gallons a day. It has saved me money (over the cost of bottled water), and it helps the environment. But most importantly, it is going to help my husband fight his cancer by providing the best in drinking, and cooking water.

  11. Joy T

    I’m buying my 4th waterwise 4000 tomorrow as the 2 I’ve been using for the past 8 years have finished their service.
    I’ve referred several customers to this excellent product and they are as pleased as me! Thanks for the glass collector and stainless steel. I see that the glass collectors are much stronger than mine, I’m looking forward to my new machine. Two of the now defunct distillers, ended service with a broken start button… maybe these have improved as well.

  12. Garrick W

    I have been using this product for several years. The one gallon countertop distiller is perfect for a small family. It is the cleanest water I have ever had. I never appreciated clean water until I had water wise clean water.

      Thank you for your review. Please contact us if you need anything in the future.

  13. Jane

    My 4000 is perfect for me! It takes up only a moderate amount of space on my counter and is an attractive unit, easy to clean. I love the pure taste of “no taste.” I was so pleased after it came, that two years ago I bought a second one to have when I am visiting in another state. I am about to purchase a 4000 for my son and his family for Christmas.

  14. Nancy L

    Just bought this distiller yesterday. Distiller the 1 gallon amount and left out on counter to cool. Poured out old water in pets’ bowls. Refilled with Waterwise water. We had two cats immediately drinking out of the same bowl at the same time. I bought this product to use for my appliances, but read the list of benefits at the back of the booklet, which included the pets water. The product preformed as stated in the booklet. We are very happy.

    • waterwise

      Thank you for your review. Happy the cats are pleased as well!
