The Clean Water Machine by Aquasana: Is It Any Good?

After reviewing our local water quality report, and finding out which contaminants our tap water might contain, I set out to find the right water filter for my family. I did some careful research and decided to purchase the Clean Water Machine by Aquasana.

So, what makes Aquasana’s Clean Water Machine a good water filter?

When compared to water treatment products from brands like Brita and PUR, it’s easy to justify purchasing the Clean Water Machine by Aquasana. In terms of quality, performance, filter capacity, and convenience, the Clean Water Machine compares favorably to popular products from these other brands.

Now let’s consider each of these criteria to determine how the Clean Water Machine compares to other popular water filters and, ultimately, help you decide which product is the best choice for you and your family.


When you shop for appliances for your home, it’s generally considered wise to invest in high-quality products from reputable brands. Buying a water filter for your family is no different.

Is the Aquasana Clean Water Machine a quality water filter? The Clean Water Machine was independently certified by NSF International (NSF) to comply with rigorous quality standards.

What does the NSF certification represent? When a water filter is NSF certified, you can be assured:

  • the manufacturer’s contaminant reduction claims have been verified;
  • the system was tested to confirm it adds nothing harmful to the water;
  • the system has been found to be structurally sound;
  • the product’s advertising, literature, and labeling have all been verified as accurate;
  • and there is testing in place to confirm the manufacturer produces a product of consistent quality over time.

How does the quality of the Clean Water Machine compare with other water filters? Unlike Aquasana’s Clean Water Machine, some water filters have not been tested or certified by NSF. However, many brands like Brita and PUR also have their water filter products certified by NSF to assure consumers they comply with demanding quality standards.

Water FilterNSF International Certified?
Aquasana Clean Water MachineYES
Brita Faucet Filtration System (FF-100)YES
PUR Faucet Filtration System (PFM400H)YES
Clearly Filtered Water Pitcher FilterNO*

* Clearly Filtered, the manufacturer of the Clearly Filtered Water Pitcher Filter, claims its product has been tested to NSF standards. However, it’s important to distinguish that NSF International itself has not certified the Clearly Filtered Water Pitcher Filter. For more information, check out NSF Certified vs. Tested to NSF Standards.

As you shop for a water filter for your family, I recommend focusing your search on products that, like the Clean Water Machine, have been tested and certified by NSF International.


When it comes to selecting a water filter to use in your home, performance should be the most important deciding factor.

Which contaminants can the Aquasana Clean Water Machine remove from your tap water? The Clean Water Machine was independently certified by NSF to reduce the amounts of 77 different water contaminants, including Lead, Mercury, and Chlorine.

How does the performance of the Clean Water Machine compare with other popular water filters on the market? When compared with popular water filter pitchers from ZeroWater and Brita, the Aquasana Clean Water Machine is the superior choice for contaminant removal.

Water FilterContaminants Reduced
Aquasana Clean Water Machine77
Brita Longlast15

However, given the Brita Longlast and ZeroWater filters are priced below the Clean Water Machine, I realize this comparison isn’t exactly fair.

So, to draw a more equitable comparison, I decided to put the Clean Water Machine up against some more advanced offerings from PUR and Brita.

Aquasana Clean Water Machine vs. Brita (FF-100) vs. PUR (PFM400H)

For this comparison, I selected 10 commonly searched water contaminants and confirmed which of the 3 water filter models perform effectively against each of those contaminants.

If a water filter was verified by NSF to remove a given contaminant, I marked it with “YES” in the following table:

ContaminantAquasana Clean Water MachinePUR (PFM400H)Brita Faucet Filtration System (FF-100)
Carbon TetrachlorideYESYESYES
Total Haloacetic Acids (HAA5)
Total Trihalomethanes (TTHMs)YESYESYES
Total Score:7/107/106/10

This exercise demonstrates the Aquasana Clean Water Machine, the PUR PFM400H, and the Brita FF-100 can protect your family from a range of contaminants. But, it doesn’t make it easy to declare a clear winner when it comes to performance.

So, I decided to compare the full list of contaminants each product is certified to filter from tap water.

Here is what I found:

  • The Aquasana Clean Water Machine reduces 77 contaminants, which is more than either the PUR PFM400H or the Brita FF-100 can filter.
  • The Aquasana Clean Water Machine filters Naproxen, Ibuprofen, Phenytoin, Perfluorooctanoic Acid (PFOA), and Perfluorooctane Sulfonate (PFOS), which neither the PUR PFM400H nor the Brita FF-100 can filter.
  • Two contaminants that the PUR PFM400H and the Brita FF-100 filter that the Clean Water Machine does not are Chlordane and Toxaphene.

Just remember, not all filters can remove every contaminant that may be present in your tap water. So, before you purchase a water filter for your family, make sure you find out exactly which contaminants you can expect the device to remove from your water.

Filter Capacity

My family uses water from our Aquasana Clean Water Machine for drinking and cooking, so we go through a lot of filtered water. If you and your loved ones drink a healthy amount of water, you’re probably interested in buying a water filter that will provide many gallons of clean water before needing to be replaced.

How often does the filter on the Aquasana Clean Water Machine need to be replaced? The filter component used in the Clean Water Machine is rated for use on up to 320 gallons of tap water.

It’s important to note Aquasana recommends replacing the filter cartridge after 3 months or 320 gallons (whichever comes first).

How does the filter capacity of the Aquasana Clean Water Machine compare with other filters? Both the PUR PFM400H and the Brita FF-100 can be used to treat up to 100 gallons of water before they need to be changed. So, in terms of maximum filter capacity, Aquasana’s Clean Water Machine stands out from the competition.

Water FilterFilter Capacity (Max.)Replacement Filter CostReplacement Filter Cost per Gallon of Filtered Water
Aquasana Clean Water Machine320 Gallons$29.99$0.094/Gallon
PUR (PFM400H)100 Gallons$16.47$0.165/Gallon
Brita Faucet Filtration System (FF-100)100 Gallons$18.99$0.19/Gallon

For the best results, always maintain and replace your water filter per the manufacturer’s instructions. Also, keep in mind the quality of your town’s tap water can impact the useful life of your water filter.


Several years ago, my family and I lived in a town where the tap water contained a noticeable amount of Chlorine. So, within the first couple of weeks of living there, I installed a PUR faucet filtration system. While the PUR filter dramatically improved the way our water tasted and smelled, it often got in the way when we used our kitchen sink to wash pots and pans.

My family and I have enjoyed using our Aquasana Clean Water Machine for two years now, and we find it to be more convenient than the faucet-mounted filter we used previously.

As long as you choose a product that fits your lifestyle and preferences, you and your family will enjoy plenty of filtered water for years to come.

Key Takeaways

Here’s why the Aquasana Clean Water Machine may be a good option for your family:

  • The Aquasana Clean Water Machine is a high-quality water filter you can count on to remove 77 different contaminants from your water.
  • Its filter is rated for use on 320 gallons of tap water, so your family can enjoy healthy amounts of filtered water between filter changes.
  • As an added bonus, the Clean Water Machine doesn’t require a lengthy installation process, so you can set it up and start enjoying filtered water in a matter of minutes.


I’ve moved several times over the years, so I know just how stressful it can be to relocate. I want to help put your mind at ease. That’s why I research and write about all the things I think you should consider when moving to a new town.
