That will depend on your area and what your local plumbers charge.

6. I’m looking for a whole house water filter for lead removal?

Order NowThe Aquasana EQ-300 uses KDF water filtration media to remove lead.

7. What is the best whole house filter location?

The best whole house  filter location is close to where your main water line comes into the home.

8. What is the filtration media used in the EQ-300 whole house water filter system?

The EQ-300 use a combination of coconut shell carbon and KDF 55 for systems that are on a municipal water supply.

9. What is required with for the whole house water filter maintenance?

There is a 5 micron sediment prefilter that is replaced every 3 months at a cost of $4 and the main tank is replaced every 3 to 5 years at a cost of $639.20 for the EQ-300.

10. Can the EQ-300 whole house filtration system be put outside?

Yes, as long as it is not subjected to freezing temperatures or direct sunlight.

11. What is the whole house water filter system cost per day?

On average it costs only about 50 cents a day to have healthy pure water flowing from every tap in your home.

12. Is the EQ-300 whole house filtration system self cleaning?

The way the system is designed it is in a continually state of backflushing to provide the highest rate of water contact with the filtration media. It does this without wasting any water.

13. Does the EQ-300 remove chloramine?

Our EQ-300-C whole house water filter system is designed to effectively remove chloramines.

14. What is the recommendation for homes that have well water?

If you’re on well water, before you buy anything, get your water tested so that we can design the right filter for you. We offer testing through a national testing lab. The cost is $180 for well water, but that cost is rebated to you instantly when you purchase an Aquasana EQ-300-Well Water Filter System.

Because well water is always different, we really like to custom tailor our whole house filters that are getting installed on a well. If you’ve got bacteria in your water, you would need to get an ultraviolet filter from us. If you’ve got uranium in your water, we would use a special ion-exchange filter, etc.

Without knowing what is in your water, we couldn’t possibly make the best recommendation for you, though we do make a generic well water system that utilizes 5 different filter medias and 6 different stages that will usually work for most water conditions.

15. What level of PSI are the whole house filter system and fittings rated for?

The EQ-300 Rhino is rated for a minimum pressure of 20 psi, not to exceed 100 psi, 60 to 80 psi being optimal.

16. Does the EQ-300 whole house filter decrease the level of water pressure?

One unit is sufficient for a home up to 3,500 square feet with up to 3 1/2 bathrooms with no loss in water pressure. If you have a larger home, you would need a second unit that would be installed in parallel. This doubles the capacity of the system.

17. Does the EQ-300 whole house water filter system remove fluoride?

The standard EQ-300  removal percentages would be theoretical because no performance certification has been established. We do, however, use activated carbon and mechanical filtration, both of which are known to effectively reduce fluoride. But keep in mind that our reduction is of TOTAL fluoride: mainly the hydrofluoro-silicic acid. We do this as a result of the isotope being of a heavier mass. The separation of isotopes is a process known as isotope fractionation, i.e. mechanical filtration. . We also have a specialized carbon that we upgrade the bottom tank to. It is the HA2 Supra media. This is great for the removal of heavy metals and greater than 90% of the fluoride while still taking care of the herbicides and pesticides (VOCs, SOCs, and THMs) as well.

FAQ From the Aquasana Website

1. What is the difference between city water and well water? — City water is pre-treated to make sure it is free of bacteria, viruses and common contamination sources. City water is regulated so that the contaminants regulated by the EPA fall within or below EPA guidelines. Well water is untreated water from an underground aquifer that is pumped into a house. Well water may contain higher than average levels of iron or sulfur, or other contaminants.

2. Why are whole house water filters considered point of entry systems? — The filtration system is installed at the point where the main water supply enters the home, delivering filtered water to all subsequent outlets.

3. What is hard water? — Hard water contains a higher than average amount of dissolved minerals (primarily calcium and magnesium), and a higher concentration of multivalent cations (Ca2+ and Mg2+).

4. Does having hard water mean it is contaminated? — No, hard water is more of a nuisance than a health issue, and is not considered contaminated. Most water sources in the USA are considered hard. Is hard water safe to drink? — Yes, hard water is healthy enough to drink.

5. What is soft water? — Having soft water means you have a lower concentration of dissolved minerals and multivalent cations in your water. The most recognizable trait of “soft” water is how much more soap lathers, as opposed to hard water, in which soap lathers less.

6. Does having soft water mean it is clean water? — Soft water does not mean clean water. Your water can be soft and still have contaminants present in the water. Soft water simple is a lower concentration of dissolved minerals and multivalent cations. Is it safe to drink? — Yes, soft water is considered potable as long as the water has not passed through a sodium-based water softener. Drinking water from a sodium-based softener increased your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals.

7. What is a water softener? — A water softener is a system designed to remove/reduce calcium and magnesium from the water by exchanging it with sodium (or sometimes hydrogen or potassium). This is done through an ion exchange resin that alters the molecular structure of the calcium and magnesium from a divalent ion to a univalent ion, making the water “softer.” Do softeners reduce chemical contamination? — Softeners do not remove chemical contamination themselves, but softeners sometimes have a carbon filter working in conjunction with the softener to treat contamination.

8. What type of filtration mediums do you use in the top tank of the EQ-300? — The EQ-300 top tank contains a KDF-55 medium (A mixture of 55% copper and 45% zinc mineral alloy) for the reduction of chlorine and certain heavy metals*, as well as a crushed mineral filter stone to enhance the water’s pH and control scale* on internal plumbing. Both media are bacteriostatic*, which means they prohibit bacteria and algae from growing or developing within the system.

9. What type of filtration mediums do you use in the top tank of the EQ-300-WELL? — The EQ-300-WELL top tank contains a KDF-85 medium (A mixture of 85% copper and 15% zinc mineral alloy) for the reduction of chlorine, hydrogen sulfide and heavy metals like iron, as well as a crushed mineral filter stone to enhance the water’s pH and control scale on internal plumbing. Both media are bacteriostatic, which means they prohibit bacteria and algae from growing or developing within the system.

10. What is KDF? — KDF stands for kinetic degradation fluxion, which is a redox filtration medium. KDF uses a unique combination of copper and zinc that creates an electrochemical reaction. During this reaction, electrons are transferred between molecules, creating new, harmless molecules and compounds. Free chlorine, for instance, is changed into benign, water-soluble chloride, which is then carried harmlessly through the water supply. Similarly, some heavy metals* such as copper*, lead*, mercury* and others, cling to the medium’s surface, thus being effectively removed from the water supply.

11. What type of medium is used in the bottom tank of the EQ-300 — The EQ-300 bottom tank contains a carbonized coconut shell medium that reduces synthetic chemicals* and VOC’s*.

12. What type of medium is used in the bottom tank of the EQ-300-Well? — The EQ-300-WELL bottom tank contains a carbonized coconut shell & catalytic medium that reduces synthetic chemicals, hydrogen sulfide gasses and VOC’s.

13. What percentage of chlorine do Aquasana Whole Home Systems remove? And for how long? — The EQ-300 is certified by NSF International to reduce >97% of chlorine for 300,000 gallons.

14. Does either the EQ-300 or EQ-300-WELL remove calcium? — No. The KDF medium in the top tank of these systems change the structure of calcium into a form of calcium called aragonite, which has trouble sticking to the inner walls of plumbing and therefore reduces the possibility of scale buildup in plumbing.

15. What is the flow rate of the EQ-300? — All Aquasana Whole House Systems perform at 7 gallons per minute (gpm).

16. Will I experience a drop in water pressure after installing the EQ-300 or EQ-300-WELL? — As long as your home is less than 3500 sq. ft. and you have 3-1/2 bathrooms or fewer, you should not experience any noticeable drops in pressure. If you have a larger home, we can build a custom system to deal with the typical water capacity of your home.

17. What is chloramine, and does the EQ-300 remove it? — Chloramine is a disinfection agent used as an alternative to chlorine in some city water treatment facilities. They use chloramines for two big reasons: (1) chloramine is less reactive, so it does not create as many disinfection by-products as chlorine, and (2) chloramine is more persistent, and remains in the treated water through the distribution network all the way to the taps in the homes the treatment facility serves. The EQ-300 is certified for the removal of chlorine, and the process of removing chlorine is similar in most respects to the process used to remove chloramine. The key difference is that chloramine exhausts the standard activated carbon in the bottom tank of the unit quickly, making the EQ-300 a little less effective at removing it*. For customers with chloramine in their water, we upgrade the media in the bottom tank of the EQ-300 to a catalytic activated carbon, which has a higher surface point. This type of activated carbon is able to handle the aggressiveness of the chloramine for a longer period of time than the standard coconut shell carbon used in the bottom tank of the standard EQ-300. The part number for this system upgrade is EQ-300C, and it is available for purchase by calling the Aquasana Water Specialists at 866.662.6885.

18. Does the EQ-300 remove bacteria or viruses? — No, if you are concerned about bacteria or viruses in your water supply, we recommend that you add a 0.35-sub-micron post-filter and an ultraviolet light sanitation system after the EQ-300. The AQ-UV-20 ultraviolet light sanitation system uses ultra violet radiation to sanitize drinking water as it passes through the system, which changes the DNA structure of microbiological contaminants and some cysts. UV light radiation also prevents bacteria and viruses from reproducing, and microbiological contaminants cannot survive without constant reproduction.
Important Note: The AQ-UV-20 will not sanitize properly without a sub-micron filter. If sub-micron filter is not used before the UV system, microbiological contaminants can hide behind microscopic particulates, which will cause the UV radiation to lose its effectiveness. This is known as a shadowing effect. A 0.35-sub-micron filter must be used before the UV system to prevent the shadowing effect.

19. Does the EQ-300-WELL remove bacteria or viruses? — Yes, the EQ-300-WELL sanitizes the water with its AQ-UV-20 ultraviolet light sanitation system in the last stage of the unit setup. The AQ-UV-20 ultraviolet light sanitation system uses ultra violet radiation to sanitize drinking water as it passes through the system, which changes the DNA structure of microbiological contaminants and some cysts. UV light radiation also prevents bacteria and viruses from reproducing, and microbiological contaminants cannot survive without constant reproduction.
Important Note: The AQ-UV-20 will not sanitize properly without a sub-micron filter (which is included in the EQ-300-WELL setup). If sub-micron filter is not used before the UV system, microbiological contaminants can hide behind microscopic particulates, which will cause the UV radiation to lose its effectiveness. This is known as a shadowing effect. A 0.35-sub-micron filter must be used before the system to prevent the shadowing effect.

20. Do I need a licensed plumber to install the EQ-300 or EQ-300-WELL? — Yes, Aquasana recommends you have a licensed plumber install the system for you, to ensure that the system is installed properly. Since most licensed plumbers carry insurance to cover any damages caused by an installation error, having a licensed plumber install the system for you will give you the security that the work was done properly and that the installation is backed up by the plumbing company’s insurance plan. Not having the system installed by a licensed plumber will void the warranty of both the EQ-300 and EQ-300-WELL.
