3-Stage Filtration Mechanism

3-Stage Filtration Mechanism

The Aquasana EQ – 1000 employs a 3-step multiple tanks filtration process. This smart design optimizes the amount of time the water is in contact with the purifying medium. The up-flow tank design prevents water from mixing, clumping, or channeling. The scientifically designed sequence system results in superior contaminant reduction.

1st Stage – Pre-Filter

The first tank of this filter system is equipped with a 5-micron filter that removes sediments, silt, rust, and microscopic particles. Although this tank is much smaller than the others in the unit, it is bigger compared to pre-filter tanks of other standard Aquasana models – EQ-300 and EQ – 600. This is because the water flows upwards into the adjacent tank at the top.

2nd Stage – Upper Tank

The upper tank contains crushed minerals and a copper-zinc oxidation medium. It removes up to 97% chlorine and stabilizes the water PH to become slightly alkaline. Alkaline water is the best for optimal health as it helps the body in its oxidation process. It works similarly to the alkaline filter in the reverse osmosis filtration systems.

3rd – Carbon Filter

The water in the filter system then flows downwards to the third tank on the lower level. The tank has a carbon filter that removes any remaining chlorine and other harmful contaminants.

Upgrade Options

The standard EQ-1000 has only three filtration stages. However, you can get upgrades at an additional cost. Upgrade options include:

A Post-Filter

A Post-Filter

The post-filter is available if you upgrade to a pro-kit. It has a 0.35-micron filter which gets rid of organic particles and microscopic cysts. Since the pre-filter is 5 microns, the 0.35-micron filter ensures that any harmful contaminants that might have managed to pass through are eliminated, e.g., insecticides, dust, and mold.

Aside from refining the water filtration process, the pro-kit also helps preserve the filtration system’s overall lifetime. It is particularly crucial for well water as it has higher levels of contaminants than city water. Besides, well water is more susceptible to pathogens and organic waste.

The pro-kit also includes a 20” pre-filter, brass fittings, bypass loop, and shut-off valves. The brass fittings are easier to install and maintain, while the shut-off valves enable you to bypass the unit when changing filters.

UV Filter

UV filtration kills over 99.9% of pathogens lurking in your water. In addition, it gets rid of viruses and bacteria such as e. Coli and giardia cysts that are chlorine resistant. It also disinfects the tank during filtration.


The conditioner minimizes scale in the water. It is a great option if your inlet water is hard water. The Aquasauna conditioner is a salt-free softener – a scale control media (SCM) filter. It does not require programming or electricity to operate. Also, it does not produce wastewater and is easy to maintain.

On the downside, a salt-free conditioner is less effective for extremely hard water. Therefore, the Aquasauna SimplySoft conditioner is recommended for water hardness levels of 15 GPG and below.

Unfiltered water may contain inorganic components such as chlorides, sulfates, bicarbonates, potassium, sodium, and magnesium. Although most of them are not hazardous to your health, they compromise the taste of your water. They may also cause precipitation, staining, and limescale accumulation. Unlike saltwater softeners, salt-free conditioners like the one in Aquasana EQ-1000 does not get rid of TDS.

Filtration Efficiency and Capacity

The Aquasana EQ-1000 is specially designed to remove chlorine from city water. According to the manufacturer, it has up to 97% purifying efficiency, aside from chlorine. It can also remove organic water contaminants such as herbicides, pesticides, VOCs, heavy metals such as lead and mercury, rust, sediment, and industrial solvents.

The system can purify up to 1,000,000 gallons of water. It has a water flow rate of 7.0 GPM. The recommended system operating temperature range is 40-90F, while the maximum operating pressure is 100psi. It is NSF42 certified for meeting the recommended safety standards.

Ease of Installation

As a whole house water filter system, the Aquasana filter system is installed at the point where the main water supply line enters your home. Therefore, this filter should not be installed after a water heater or on the hot water line.

The most ideal installation location is indoors, away from direct sunlight, as extended exposure to bright light and heat may wear off the plastic components and filter housing. If you have no option but to install it outdoors, ensure that it is protected from direct sunlight and freezing temperatures.

Depending on the specific filter’s dimension, ensure there is enough space and a few inches allowance.

Although you could DIY install the unit, the manufacturer recommends hiring a professional plumber for the task. Furthermore, some local codes stipulate that you hire a licensed plumber or installation expert when the installation involves disrupting a portable water line.

The operating efficiency of this system relies heavily on proper installation. For a leak-proof installation, ensure the following:

  • All fittings are tightened
  • Only use NSF-certified plumber’s tape for sealing threaded fittings. Avoid using primer or glue on pipe dope or PVC
  • Choose the right installation location depending on the size of the tank
  • If the mainline water pressure exceeds 100psi, install a water hammer arrestor and a pressure relief valve.
  • If your demand for clean water is high, consider installing a double manifold system. It includes two sets of filters and doubles up the filter’s maximum water capacity to 2,000,000 gallons.

Care and Maintenance

The Aquasana EQ-1000 is relatively easy to maintain. You may occasionally clean the exterior of the filtration system. Use warm water, soap, and a soft cloth, and then rinse with fresh, clean water. Avoid using chemical cleaning products as they will wear the system’s housing.

Depending on the sediment level of the inlet water, you may need to replace the pre-filter every two months to prevent sediment build-up and to clog. The reduced water flow rate is one of the most obvious signs that the pre-filter cartridge needs to be replaced.

Post filter cartridges should be replaced every six months, while UV lamps should be replaced every 12 months. If you opt for a unit with a water conditioner, replace the conditioner every six years.

The manufacturer insists that you use only their replacement parts. Using replacements parts from other companies voids the warranty and ay compromise the filter’s operating efficiency.

Aquasana offers an auto-shipment filter replacement program referred to as “Water for Life.” It is a no-contract program whereby members have replacement parts shipped to them at no shipping cost. The program also enables you to lock in a 15% discount on filters.

Warranty, Guarantee, and Customer Support

Aquasana offers a 10-year warranty and 90-day money-back guarantee on the EQ-1000. In addition, the installation kit, including pre-filters, post-filters, and fittings purchased with the original system, are covered separately in a one-year limited warranty.

The warranty covers the owner of the home where the unit is first installed. It becomes void if removed from the original point of installation. It is restricted to single-family residences only in the US. The warranty covers defects in material and workmanship.

Here is a video overview of the Aquasana EQ-1000 as highlighted by the manufacturer.


Does the Aquasana EQ-1000 Get Rid of Fluoride?

The best method of removing fluoride is reverse osmosis. Aquasana EQ-1000 does not have a reverse osmosis filter; therefore, it does not get rid of fluoride.

What are the Factors to Consider When Buying a Whole House Filtration System?

When buying a whole house water filter, there are certain factors you need to put into consideration. For example, water source, water quality, types and level of contamination, the lifetime of the filtration units in consideration, maintenance requirements, and your budget.

For instance, if you have well water with high levels of contaminants, it is best to go for a multi-purifier with a post-filter, UV filter, and conditioner or softener. If you have relatively clean city water with high chlorine levels, then the standard Aquasana EQ-1000 may be sufficient. If you opt for upgrades, ensure you have adequate space for their installation.
