Some Quick Facts About Water Pollution

Before we dive into the subject at hand, looking into the best Aquasana water filtration and softening systems, to be specific, let’s first go over a few facts about water pollution so that you can better appreciate the importance of water filtration and softening systems. Here is a quick rundown of what you must know:

  • Common drinking water pollutants (city water): Arsenic, cadmium, chlorine, copper, E. coli, fluoride, lead, Legionella, mercury, nitrate, nitrite, turbidity.
  • Common drinking water pollutants (well water): Microorganisms, heavy metals, nitrites, nitrates, radionuclides, fluoride, organic chemicals.
  • Potential health effects of drinking polluted water: Depending on the exact water pollutant you are dealing with and the severity of the situation, some of the health effects that can emerge if you don’t purify the water include increased risk of cancer, reproductive problems, cardiovascular system problems, damage to the nervous system, liver, kidneys, spleen, and gastrointestinal illness, to name a few.
  • The hard water issue: While it might not directly affect your health necessarily but only impact your hair and skin health and appearance, hard water is an issue that you must solve if you are dealing with it since it leads to damage in water-using appliances and pipework.

Other notable general and performance-related information:

  • Chlorine removal: Municipality treated water contains quite a generous amount of chlorine fully on purpose as the chemical has the property to destroy bacteria and other microorganisms lurking in the water, making it healthy for consumption. It does, however, leave an unpleasant smell and taste behind that makes it discouraging to continue hydrating with the water. With an efficiency rate of 97% when it comes to the reduction of chlorine content, the system ensures the water will taste and smell fine, and that you won’t inhale chlorine vapors when you bathe anymore either.
  • Other water contamination issues it solves: The list is absurdly long when it comes to potential toxins and impurities lurking in the water, so we will only highlight the ones that stand out the most and are generally present in tap water, more precisely VOCs, organic chemicals, and heavy metals. This is just to name a few, so keep this aspect in mind as it makes a difference toward the desirability of the system.
  • Up-flow design: The dual tank feature grants it with this design perk, and what it implies is that the water enters into contact with the pollutant grabbing media for a longer amount of time to enhance the process efficiency.
  • Warranty: As it is estimated for the system to provide water purification for approximately 6 years, Aquasana backs it with a 6-year warranty which covers defects in materials and workmanship. Beware that damage that comes from clogging which results from the user not tending to regular maintenance, damage caused by fires or floods, damage caused by non-potable water supplies, and direct damage inflicted by the user cause the warranty to be voided, so you won’t benefit from free repairs or replacements in these situations.

Filter media

  • Sediment pre-filter: Its purpose is to catch the smaller pollutants so that it facilitates the work of the accompanying filtration stages. These polluting particles include the likes of sediment, rust, and silt.
  • Activated carbon filter: Carbon is utilized in various systems, including air purifiers, as it has powerful decontamination capacities. In water filters, it is used to eliminate and decrease pollutants like pesticides, herbicides, and a wide range of chemical compounds.
  • Copper-zinc and mineral stone filter: The dual tank also comes with this filter that tends to remove chlorine, which is the main culprit of water contamination. Other pollutants and compounds it eliminates include heavy metals and scale, and it represses the growth of algae and bacteria as well.

Test results

We tested the water at our office to see how it fared in terms of hardness, and when the results came in we were a bit shocked to learn that we had 135 mg/L, so hard water was indeed a major issue here. This did explain why all our mugs and glasses looked always stained, no matter how much we washed them, and why there were always clear deposits on the sinks and in the toilet. However, after installing the Aquasana SimplySoft and sending a water sample to the lab for testing, we were pleasantly surprised to see that in a few days levels had dropped from 135 mg/L to only 23 mg/L. Now we are finally within safe parameters and can say the water is soft and won’t put our precious coffee maker in danger anymore!

Optional System Upgrades

Even if the system you select is as standard as they get, you do have the option to add a few extra options to expand its usability. Maybe you tested the water and you noticed that it contains bacteria, which seems odd to you considering that you source the water from a municipality treatment plant. This does not mean that you have to acquire a well water system but rather a normal unit that is suited for city water supplies and simply opt for a UV sterilization add-on to solve the extra issue at hand. This is only one example to demonstrate how you can add to a product’s versatility in use. Next, we will revise the technologies that you can separately opt for to add to your specific selection and make it cater to your needs and expectations.

Salt-Free Softener: Scale Control Media or SCM is utilized to diminish scale that is caused by hard water through the means of softening it, the process being safe and natural as salt is not involved in it.

Sterilight UV Filter: Provides a safeguard against microorganisms so that you don’t ingest water that contains them and ultimately have your health deteriorate as a result of this action. Its efficiency rate in this department is 99.99%, so you can see why this is a rather mandatory add-on.
Pro Grade Install Kit: The kit contains upgraded components like brass fittings which are easier to install and maintain as time passes, and bend supports and shut-off valves which ensure easier filter changes.

Frequently Asked Questions

Is a whole house water filter worth it?
While for municipality water the answer is a bit iffy since there is prior treatment involved, if you use well water, the answer is definitely yes. In this specific situation the water is not treated, so all the sediments, microorganisms, and chemicals are left in it. This renders the water unsafe for use regardless of the purpose you have in mind – hydration, bathing, cooking. If the water is hard, it will even affect appliances that use water in their operation, like the coffee maker or washing machine, so it’s worth acquiring a whole house water filter like the Aquasana models presented here for your safety, as well as the safety of certain appliances.

How does the whole house water filter system work?
The Rhino systems from Aquasana pass the water through a 3-step process, as follows:

  1. The first step is where the pre-filter process occurs. In this phase, large particles and pollutants are removed, preventing damage to plumbing and appliances, and helping the water acquire that clear, clean aspect.
  2. Phase two is where the Rhino filtration takes place, removing 97% of chlorine taste and odor in the process. In this stage, an activated carbon media also takes action, reducing the remaining impurities.
  3. The final step is where the post-filter comes into play, finishing off the process by catching any sediment and organic particles that may have passed after the previous steps.

Does it reduce water pressure?
If properly selected and maintained, the system won’t affect water pressure in the slightest. Nonetheless, if the system isn’t matched to the plumbing or if you don’t change the filters on time and sediments become obstructions, water pressure will inevitably drop.

Does it remove chlorine?
Yes, all of the Aquasana whole house water filters we discussed here remove chlorine with a 97% efficiency, leaving the water tasting and smelling better as a result. This goes for systems manufactured by other brands too since one of the main focus points of these filters is chlorine reduction because of the contaminant’s prevalence in tap water everywhere.

Does the system need a softener?
If you have problems with water hardness, you need to consider a system with a softener, or specifically acquire a whole house water softener if this is the sole issue that worries you.

How do I maintain the system?
With any type of filtration system, maintenance is comprised of filter media replacement in due time. The period between replacements differs from one media to another, so check the accompanying manual to see when it must be performed as, for example, activated carbon filters likely need substitution on a more frequent basis than UV light filters.

How do I size the whole house water filter?
There are two aspects that you must take into consideration when sizing the system – how many bathrooms, kitchens, and water-using appliances there are in your home, and how many people share them. For example, you might be tempted to think that a house with 2 bathrooms, a kitchen, and a hand few of water-using appliances might work with a small-size system, but if there are 6-7 people who live in that house water demand is surely high, and thus there’s need for a larger-capacity system.

Does Aquasana have a return and refund policy?
All products that you buy directly from Aquasana come with a 90-day trial period. There are no questions asked upon your return of the product, so if you are dissatisfied with the purchase for any given reason, you can ship it back to the company. You will receive your money back within 15 business days of receipt of the product you have returned. Make sure that the package contains all the original contents and that nothing is damaged.

What other products does Aquasana sell?
Aside from whole house water filters, Aquasana sells whole house water conditioners, under-sink water filters, countertop water filters, shower filters, water bottles, and water pitchers. Thus, you are bound to find a water filter product to suit your demands and budget since their product range is quite diversified.

Does Aquasana ship outside of the U.S.?
Yes, Aquasana products are accessible in plenty of other areas too, including Australia, Belgium, Brunei, Cambodia, Chile, China, Cyprus, Denmark, Ecuador, El Salvador, England, Finland, Germany, Greece, Hong Kong, Hungary, Indonesia, Laos, Malaysia, Myanmar, New Zeeland, Norway, Peru, Portugal, Romania, Singapore, Slovakia, South Africa, Sweden, Thailand, Trinidad and Tobago, Uruguay, and Vietnam.


Irrespective of the water purity and issues that afflict it, Aquasana is a company that you can depend on to offer a practical fit for your concern. The systems it produces are reasonably priced considering their pollutant removal capabilities, and they all boast long life expectancies without necessitating much in the way of upkeep or filter media replacement. Furthermore, like all Aquasana products, they are manufactured with the good of the environment in mind, being engineered to promote minimal water waste.

The Aquasana EQ-600 and the EQ-1000 are among the company’s most sought-after products as they deliver a 97% chlorine reduction proficiency, ensuring a better taste and lack of smell when it comes to the water that comes through all taps in your home. Moreover, this specific property of the systems helps enhance lung health as well, seeing how chemical-filled vapors when you bathe won’t pose an issue anymore. Their filtering means are identical, the sole difference between them standing in their capacity as the EQ-600 is a 600,000-gallon capacity product, whereas the EQ-1000 is a 1,000,000-gallon capacity model.

Nevertheless, the aforementioned models are only suited for municipal water supplies. If you are dealing with well water, however, then you require the Aquasana Rhino. It employs UV sterilization to destroy all microorganisms in your drinking water, and it also emphasizes the reduction of other pollutants, including the likes of pesticides, herbicides, and VOCs.

The manufacturer even provides a solution for those confronted with hard water through the release of the highly effective Aquasana SimplySoft Salt-Free Softener. As implied by the name of the product, salt is not used in its operation, so it provides a natural manner to impede scale build-up.

As long as you test the water supply to see what are the issues afflicting it and you make sure to size the system you pick to the size of your home (you can use the number of bathrooms as guidance, most systems are rated according to this specific criteria too, so it won’t be difficult to figure out what is compatible in your situation), with an Aquasana product you are sure to enjoy a cleaner, healthier water throughout all taps and outlets.
