Aquasana Rhino Whole House Water Filter FAQs

Capacity and Specifications

What's the difference in flow rate between the Countertop and the Rhino?

The difference between the EQ-300 (Rhino) and the AQ-4000, is that the Rhino filters water at 38 litres per
minute, and the AQ-4000 filters water at ~ 2 litres per minute. This slower flow rate allows for a longer contact time with the media, and because it was designed to only filter 2400 litres (instead of 12,000,000), it can concentrate more heavily on more aggressive contaminants, like VOC's, MTBE and THM's.

Why will I still need a countertop if I am purchasing a Whole of House filter?

Because the Rhino was designed for whole house applications, and needs a higher flow rate, it is a 5 micron
filter which will remove sediment 4 times smaller than is visible to the unaided human eye. The AQ-4000, on
the other hand, is a .5 micron filter, that will remove cysts which are 40 times smaller than can be seen by
the human eye.

Also, the Rhino was not designed for the removal of lead (though it will reduce it significantly), as the
majority of the lead in your water comes from inside your house. You still need to filter your water before you drink it.

Does the Rhino remove chloramines?

The Rhino Whole of House unit will treat 12,000,000 litres for chloramines, or about 4 years for the average
Australian home.

Why do we need a whole of house filter?

The U.S. EPA has stated that "..every household in America, on municipally treated water, has an elevated
level of Chloroform gas in the air, specifically from showering, washing dishes, washing clothes and flushing
toilets." The Rhino will filter out the Chlorine, so that you are not exposing your family to the carcinogenic and asthma and allergy irritating effects of Chloroform gas everytime you turn on a faucet, flush a toilet, wash dishes, wash clothes, shower, or bathe.

In what capacity is the Rhino superior to a shower filter?

The Rhino EQ-300 is also the only perfect shower filter there is. Because of the size constraints, the difficulty in filtering hot water (90-110 degrees), and the 7 litre per minute flow rate, no shower filter can remove all of the Chloroform, Chlorine and THM's present in tap water. The EQ-300 is also the only viable way to filter bath water. This is because there are no standards for bath faucets, and there is no way to design an adapter that will fit all or most.

How long does the EQ-300 whole house water filter system last?

The EQ-300 unit is certified for a 12,000,000 litre capacity at 38 lpm, the highest certified capacity of any
whole house water filter system. The main filter unit can be easily replaced every three years at the low cost
of $590.00, no plumber needed. The sediment pre-filter should be replaced every 3-4 months.

What media is in the top unit of the EQ-300?

KDF-55. This is a copper-zinc alloy filter media, specifically designed to remove chlorine, heavy metals, and
micro-organisms from drinking water.

What medias are in the bottom unit?

Bituminous carbon and coconut shell carbon.

How much time is involved in the installation of the whole house water filter?

Typical installation is 1-2 hours when done by a licensed plumber and costs about $120 to $180. Installation
by a licensed plumber is required for warranty qualification.

What is the size of the whole house unit?

The EQ-300 whole house water filter system is 1.1m tall and 22cm in diameter at the base. It requires a total
line length of 58cm for proper installation of the pre-filter and the ball valve assembly. The filter unit comes in two packages, weighing 24 kilos and 3 kilos, respectively. All materials are FDA approved food grade plastics or fibreglass.

Does the whole house filter use standard 1.8cm piping?

The EQ-300 comes standard as 1.8cm but can be changed to 2.45cm piping. 2.45cm piping must be specially
ordered.

Is the pre-filter on the whole house unit a regular sediment filter?

The pre-filter is a standard 25cm, 5-micron spun cartridge.

What is the flow reduction of the EQ-300?

The EQ-300 utilizes a 27 lpm flow rate.

The installation illustration shows the EQ-300 installed on a horizontal run of pipe; can this unit be installed on a vertical run of pipe making the unit lay on its side?

The EQ-300 must be oriented vertically. The vertical pipe can be cut and run to and from the system by using
L piping.

What items come in the Rhino whole house filter package?

The EQ-300 whole house filter comes complete with main filter unit, pre-filter, installation kit, and required
hardware.

Benefits of whole house filtration

What are the benefits of whole house filtration?

By filtering all of the water that enters your home, you not only greatly enhance the healthfulness of your household water, but you also dramatically improve your indoor air quality. According to the U.S.

Environmental Protection Agency (EPA), "Every home in America has an elevated level of chloroform gas present due to the vaporization of chlorine... from tap and shower water." Chlorine vapors are a suspected cause and irritant of respiratory problems such as asthma, bronchitis, and allergies. Filtered water will improve every aspect of your family's health.

Does the whole house filter system have any benefits for laundry and/or dishwashing?

The EQ-300 will remove any VOCs or chlorine that may be embedded in clothing when unfiltered water is used in the washing machine. Also, colors will last longer and look newer with the chlorine removed. The dishwasher releases more VOCs and chloroform into the household indoor air than any other source besides the shower. The EQ-300 prevents this toxic gas from being released. Filtered water in the dishwasher also reduces film or soap scum on dishes. For both laundry and dishwashing, filtered water reduces the amount of detergent you need to use in each cycle.

Contaminant Removal

What contaminants does the EQ-300 remove?

The EQ-300 will:
• Remove radon, VOCs, pesticides, metals (however, use of the AQ-4000 is still recommended, as houses built before 1978 will likely reintroduce lead)
• Reduce TDS down to 5 microns
Alkalize drinking water, raising the pH to about 7.5.

I have a well. Do you have a system that is designed for well water?

The EQ-300 can be used with well water as long as the water does not contain any bacteria or viruses. If
bacteria and viruses are present, a UV post filter can be used in conjunction with the EQ-300 to remove these contaminants.

Does the EQ-300 remove a sulfur odor from the water?

Yes, the EQ-300, AQ-4100, and AQ-4000 will all remove sulfur smell.

Are drinking water and shower filter units still necessary with a whole house filter?

The shower system is not needed, as the shower filter and whole house filter remove the same contaminants.
However, we still recommend the use of the drinking water filter because it removes additional contaminants (such as Giardia and Cryptosporidium) that the whole house filter does not remove. In addition, the drinking water filter will remove lead and other contaminants that are introduced from the home's plumbing after water goes through the whole house filter.

Does the EQ-300 soften the water?

The EQ-300 will soften hard water a small amount, but it is primarily designed to remove chlorine,
herbicides, pesticides, heavy metals, industrial solvents, and sediment. However, you may install a water
softener to work in conjunction with a whole house water filter without any problems.

What are the differences between whole house units and softeners?

Softeners use salt to push minerals like iron and calcium out of the water, similar to the way insulin pushes
sugar out of blood. The whole house water filter is designed to remove chemicals and heavy metals, while
retaining good, healthy minerals. The EQ-300 will reduce calcium and iron down to 5 microns with
mechanical filtration.

Are whole house systems (P.O.E. - point-of-entry) better than countertop filters (P.O.U. - point-ofuse)?

P.O.U. systems are by far the best way to ensure the highest quality water since many water-borne
contaminants come from the plumbing in your house, especially lead and vinyl chloride from the piping. By
filtering water at the point-of-use, you remove contaminants just prior to consumption, eliminating the
chance of recontamination. Point-of-entry systems are very beneficial in that they provide filtered water to all baths and showers as well as any other water appliances. When you filter all of the water entering your
home, you improve not only the healthfulness of the water, but the indoor air quality, as well. Point-of-entry
filtration results in the removal of chlorine and other chemicals that vaporize and contaminate the indoor air.

Glossary of terms

Chlorine: Chlorine is a yellowish, poisonous gas with a pungent odor, widely used as a disinfectant in water. Ingestion of chlorine can lead to bladder, rectal, and/or breast cancer.

Chloramines: Chloramines are a disinfectant formed when chlorine is combined with ammonia. They are composed of three chemicals: monochloramine, dichloramine, and trichloramine. Recent research identified trace amounts of other disinfection byproducts (such as n-nitrosodimethylamine) created in drinking water by using chloramines. Chloramines in air are strong respiratory irritants.

Chloroform gas: A chemical compound, it is a member of a subset of environmental pollutants known as trihalomethanes, a by-product of chlorination of drinking water and a long-standing health concern.

MTBE: MTBE is a chemical compound, typically used as a fuel oxygenate or additive to unleaded gasoline. The specific health risks of MTBE are currently pending EPA investigation.

SOCs: Synthetic organic chemicals (SOCs) are man-made chemicals that can make their way into drinking water. Ingestion of SOCs in drinking water has been linked to at least four types of cancer.

THMs: THMs are chemicals that occur in drinking water as a byproduct of water chlorination. They are highly carcinogenic and can affect nervous system, kidney, and liver functioning.

VOCs: Volatile organic compounds (VOCs) refer to a large number of chemicals that can occur in drinking water as a result of human industry. These chemicals can cause cancer and affect liver and kidney functioning when ingested in drinking water.

Underwriters Laboratories: The Underwriters Laboratories (UL) is a consumer health and certification organization that evaluates products for health and safety risks.
