Aquasana Rhino EQ-1000 Whole House Water Filter

  •    Price: $$$$
  •    Flow Rate: 7 gpm
  •    Filt. Capacity: 1,000,000 gal
  •    NSF Cert.: 42
  •    Warranty: 10 Years

It can get a little confusing to talk about the many different options and modifications that you can choose from when it comes to Aquasana’s Rhino whole house water filter system. So please bear with us!

Let’s start by listing each basic version and see how it goes from there:

  • Aquasana’s Rhino EQ-600 provides filtered water throughout your entire home for 6 years or 600,000 gallons, whichever comes first. The system is for chlorinated tap water only.
  • The Rhino EQ-1000 is Aquasana’s biggest whole house unit and delivers great-tasting and chlorine-free city water for up to 1 million gallons or 10 years.
  • Next we have the Rhino EQ-400 designed for municipal water disinfected with chloramine. Chloramines are more stubborn than chlorine and therefore require upgraded filter media which is why many filters are not capable of removing them effectively. Filtration capacity: 3 years or 400,000 gallons.
  • And lastly we have the Rhino EQ-Well-UV which stands out from the others because it’s suited for well water treatment. This is also why it includes the Sterilight ultraviolet filter: To protect you from bacteria like E. coli, viruses and other pathogens commonly found in wells. The capacity is 500,000 gallons or 5 years.

Oh and there is the Aquasana Rhino EQ-300 which has the lowest filtration capacity of all (300,000 gallons) and again is meant for city water treatment. However, the unit was upgraded to the EQ-600 doubling its capacity. This is why the EQ-300 cannot be purchased from the Aquasana online store any longer (except for the replacement tank). It’s still available on Amazon, though.

Please note: All systems are rated at 7 gpm flow rate which is sufficient for families of up to 4 living in larger homes without experiencing a noticeable pressure drop.

Each Rhino comes with a 5-micron pre-filter that catches rust, sediment and silt. The goal here is to increase the lifespan of the media that makes up the next filtration stages:

  1. Activated carbon removes chemicals and VOCs like herbicides and pesticides from your water.
  2. The mixture of copper and zinc mineral alloy a.k.a. KDF-55 combined with mineral stone reduces chlorine and some water soluble heavy metals (e.g. copper and lead), enhances water pH and controls scale.

Both media types are bacteriostatic meaning that they inhibit bacteria and algae growth.

Exceptions are the EQ-400 and the EQ-Well-UV system.


The EQ-400 includes upgraded catalytic carbon and features larger tanks for increased water contact time and maximum chloramine removal.


Instead of just activated carbon, this setup also uses catalytic carbon to eliminate hydrogen sulfide gasses. Although not posing an immediate health thread, hydrogen sulfide has a very distinctive and unpleasant smell similar to rotten eggs. Furthermore, the EQ-Well-UV works with KDF-85 medium rather than KDF-55. The higher copper content also helps with the reduction of hydrogen sulfide as well as heavy metals.

What’s more, as an extra safety measure for well supplies the system comes with a post-filter rated at 0.35 microns to reduce any remaining sediment and organic particles.

Each of the whole house filter systems can be upgraded with the SimplySoft salt-free water softener – actually “descaler” would be the correct term – and the Pro Grade Install Kit.

The softener is meant for reducing scale caused by hard water, obviously. Without going into too much detail, it requires neither salt nor harsh chemicals to alter the adhesion characteristics of calcium and magnesium. This forces them to bind to each other instead of your plumbing and household appliances.

As a result, the longevity of your water heater, dishwasher, washing machine, etc. is likely to increase. Another benefit is better soap lathering.

The advantage of saltless water conditioning is that

  • (A) it requires no electricity or programming,
  • (B) the system is very easy to maintain and
  • (C) it does not produce wastewater.

All this is going to save you time and money in the long run. You also don’t have to worry about consuming the water if you are on a salt-restricted diet.

The biggest downside is that salt-free conditioning is always less effective than traditional salt-based softening – no doubt about that.

By the way, the SimplySoft softener can handle hardness levels of up to 25 grains per gallon and exceeds at 15 gpg or less.

As for the Pro Grade Install Kit, the included brass fittings, shut-off valves and bypass loop make the install somewhat easier. And for the EQ-300, EQ-600 and EQ-1000, you also get the additional sub-micron post-filter that the EQ-400 and well water Rhino already come with. Like we said, the filter helps to get rid of remaining sediment and organic particles.

And lastly, you can add the Sterilight UV filter to all 3 city filter systems as an extra safeguard against waterborne pathogens. If you are on a well a UV filter is mandatory. For city supplies it depends on your individual situation. It definitely is great for peace of mind though.

FYI: Ultraviolet light destroys up to 99.99% of the microorganisms that might be lurking in your water.

What We Like

There are a couple of things that we like about the Aquasana Rhino.

For one, it delivers great-tasting and clean water to every outlet in your house. This includes your shower so that your body’s overall exposure to chemicals, mainly chlorine, will be reduced for more moisturized hair and skin.

Another benefit of clean water throughout your entire home is improved indoor air quality, as less volatile chemicals can evaporate.

And because the Rhino’s main tank applies upflow filtration the risk of clogging is slim.

On top of that, NSF Standard 42 certifications for the EQ-300, EQ-600 and EQ-1000 guarantee chlorine removal of at least 96.9%. For the EQ-300, this is guaranteed for 300,000 gallons or 3 years, whichever comes first. For the EQ-600, it’s 600,000 gallons or 6 years. And for the EQ-1000, it’s 1,000,000 gallons or up to 10 years.

The Rhino for well water is not certified since it does not aim at chlorine reduction.

Did we mention that you get a limited lifetime warranty for all Rhinos? The warranty covers defects in materials or workmanship in manufacturing.

Aquasana whole house water filter reviews: Rhino


Installing one of Aquasana’s whole house filters is in no way more complicated than installing a competitor system if it was not for the cheap plastic connectors. Also, not having it hooked up by a licensed plumber will void the warranty. So think twice about whether or not you really want to proceed with this.

If so, here is a step-by-step outline of the process (steps for EQ-Well-UV may vary):

Installation of your system must comply with existing state and local plumbing codes.

1. Picking the Right Location

The best installation location is somewhere in the inside and out of direct sunlight. Choose a spot close to where the main water line enters your home and upstream of the water heater.

It is also very important that you install the Rhino in upright position to maximize filtration effectiveness. And make sure to keep the tank upright at all times during the setup.

Aquasana recommends a minimum clearance of 50″ for tank height and a minimum of 30″ for floor space.

2. The Install

  1. Remove the red shipping caps from the inlet and outlet ports on the main tank.
  2. Precondition the filter media by flushing it properly:
    1. Use the adapter (included) to connect a garden hose to the main tank’s inlet port.
    2. Slowly turn on the water and allow it to flow out of the outlet port. Use a bucket or drain for this step.
    3. The initial flushing usually takes several of minutes.
    4. Now turn on the water supply for 30 seconds, then close it for 30 seconds. Repeat this process for approximately 15 minutes until the water comes out clear.
    5. Make sure that the white washers are properly set inside the inlet and outlet ports.
    6. Disconnect the garden hose.
  3. Put the main tank into your desired installation location.
  4. Shut off the main water supply.
  5. Install the unit to the main water line. Be careful not to over tighten any fittings to prevent leakages. Also, do not use pipe dope. Otherwise, your warranty will be void.
  6. Make sure to support the inlet piping assembly by using support brackets (included).
  7. Slowly turn on the main water supply.
  8. Check for leaks.
  9. Open a nearby faucet and let the filter system flush for 5-10 minutes.

Filter replacements are quick and easy.

You should check the sediment pre-filter once per month. As soon as you notice a considerable decrease in pressure, it’s time for a replacement. The average lifetime is no more than 2-3 months.

As for the main tank, filtration capacities are listed above. Once you hit the limit, replace the unit in its entirety. You might also want to consider adding a water meter for convenience.

The optional post-filter should be replaced once or twice a year. If you also own the UV filter stage, annual replacement of the bulb is a must, says Aquasana. Don’t worry, changing the bulb is not overly complicated.

Last but not least, the outside of the entire system can be cleaned with warm dishwater. Rinse with clean water afterwards. Remember to never use chemical cleaner on the filters’ exterior surface in order to not damage their housings.



What We Don’t Like

  • We miss additional certifications according to NSF standards for contaminants other than chlorine. For example, the Aquasana Rhino EQ-400 is not certified for chloramine reduction.
  • The cheap plastic fittings are not only prone to leaking, they also make the installation much more difficult. The best solution is to replace them with copper or brass pieces. We also don’t like that a DIY install voids the manufacturer warranty.
  • Speaking of warranty, we read reviews from customers saying that they had difficulties working with Aquasana when warranty claims became an issue.
  • Some folks had bad experiences with unresponsive customer support, while others said that customer service was outstanding from beginning to end.

Our Verdict

Bottom line: The majority of users are more than happy with their version of the Aquasana Rhino whole house water filter and would buy from the company again.

Each system provides odor-free water with a clean taste which is the main goal here. If you want to remove specific contaminants, however, this might not be your best choice. NSF certifications for contaminant reduction rates other than chlorine are missing. One of the biggest cons are warranty issues.

Our verdict: 4 stars!

Loooking to get a Aquasana Rhino 6-Year 600k Gallon Whole House Water Filter Salt-Free Softener+UV and need to know how much horizontal space is needed.

    Gene says 8 months ago

    The length including the pre-filter, shut-off valve, etc. is 27″, so you need that + enough room for additional piping (depending on your setup).
