FAQ
Aquasana FAQs
1. 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 throughout your home.
Since most licensed plumbers carry insurance to cover any damages caused by an installation error, having a licensed plumber install the system will give you the security that the work was done properly and peace of mind in knowing that the installation is backed up by the plumbing company's insurance plan.
The OptimH2O® Whole House water filter is rated for 4.8 gallons per minute (gpm). True flow rate will vary with influent water pressure.
A home that is less than 3,500 sq. ft. with 3.5 bathrooms or fewer should not experience any noticeable drops in pressure. For homes larger than this, our knowledgeable Customer Service Team can build a custom system to accommodate the water capacity of the home. For more information, call us at 877-996-2875.
The OptimH2O® is IAPMO tested and certified to remove over 99% of lead and cysts, over 97% of PFOA/PFOS, and up to 90% of chlorine and chloramines. The Rhino® Whole House Filters are tested and certified for the removal of up to 97% of chlorine.
The tank contains a giant, ultra-dense carbon block that offers superior filtration compared to granulated media. Catalytic and active carbon are combined to perform ion-exchange and sub-micron filtration.
The OptimH2O is certified by IAPMO to reduce over 90% of chlorine for 100,000 gallons or up to 12 months.
The OptimH2O is internally tested to reduce more than 90% of chloramine. Chloramine is a disinfection agent comprised of chlorine and ammonia used as an alternative to chlorine in some city water treatment facilities.
City water is pre-treated to make sure it is free of bacteria, viruses, and common contamination sources. It’s also regulated per the Environmental Protection Agency’s (EPA) guidelines.
Well water comes from an underground aquifer that is pumped into a home and is typically untreated. Well water may contain higher than average levels of iron or sulfur, or other contaminants.
Hard water, while mostly a nuisance, occurs when dissolved minerals clump together to produce scale that can harm your internal pipes, plumbing, and home appliances. 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+).
No, hard water is not always considered contaminated. Most water sources in the USA are considered hard.
Hard water can be city water or well water meaning it may or may not be pre-treated. The minerals that make water "hard" are not considered contaminants, but hard water can still contain additional contaminants that are not safe for consumption.
Soft water is water that has either been treated by a water softener or naturally contains less hard minerals. The most recognizable trait of "soft" water is how much more soap lathers, as opposed to hard water.  Soap lathers less due to the higher concentration of minerals. Water softeners reduce the negative effects of dissolved minerals in water that can clump together and produce scale buildup.
Soft water does not mean clean water. Your water can be soft and still have contaminants present in the water.
Yes, soft water is considered potable. Drinking water from a sodium-based softener increases your daily intake of sodium, which can lead to health problems in sodium-sensitive individuals. Please keep in mind that a water softener is not a water filter. A water softener does not remove contaminants present in your water.
A salt-based water softener is a softener system designed to remove/reduce calcium and magnesium from the water by exchanging it with sodium. This is done through an ion exchange process that alters the molecular structure of the calcium and magnesium from a divalent ion to a univalent ion, making the water "softer."
Softeners do not remove chemical contamination themselves, but softeners sometimes have a carbon filter working in conjunction with the softener to treat contamination.
Our whole house filters do not remove calcium. To reduce hard mineral buildup, we recommend adding on our Salt-Free Water Conditioner.
It is recommended to disinfect all water supplies that are not protected by a municipal water (city water) source.  By providing your own disinfection, you are ensuring the safety of your water supply for you and your family.
f you use water that comes from a municipal water supply and wish to provide your family with added peace of mind, a UV Filter acts as an added safeguard against bacteriologically contaminated water.
We offer the UV Filter as an add-on to the OptimH2O® that is designed to render bacteria and viruses inactive. The UV Filter safely sterilizes up to 99% of illness-causing organisms.
Yes, UV filtration is the best available technology proven to treat protozoan cysts. The levels required to inactivate these cysts are quite low: less than 10 mJ/cm2 for 99% sanitization of both Cryptosporidium parvum and Giardia lamblia.
E. coli requires a UV dose of 6-10 mJ/cm2 in order to render it inactive or sterilize by 99%. The Aquasana UV Filter delivers a minimum of 30 mJ/cm2.
UV filtration typically offers a 2-log reduction (99% sanitization) for bacteria, cysts, and most viruses. UV filtration is more effective and more eco-friendly than chemical disinfection processes at destroying a wide range of these contaminants.
UV filters are extremely economical to operate. A typical 10 gallon per minute (gpm) UV filter operates on the same power requirements as a 40-watt light bulb!
No, UV is a physical disinfection process. It does not change the taste or odor of the water. It simply provides safe, reliable disinfection while adding nothing to your water.
No, the UV filter should be left on whether you are using water or not. The lamp ages regardless of the amount of water drawn through the system. By leaving the unit on, you will eliminate the potential problem of having contamination pass through the filter while the unit is off. However, if water is drained from your disinfection system, your UV filter must be switched off.
UV lamps have a powerful life of approximately 9,000 hours, which means that the lamps require annual replacement. The UV light may offer illumination beyond 1 year, however there will not be enough UV energy to provide adequate disinfection. Proper maintenance of any pre-treatment is also required. Additionally, the sleeve must be cleaned at least once a year.
Yes, our UV filter is designed for water that has already been filtered through a home filtration system and not as a standalone unit. For UV filters to be effective, it is recommended that the influent water contain the following:
  • Iron < 0.3 ppm (0.3 mg/L)
  • Manganese < 0.05 ppm (0.05 mg/L)
  • Hardness < 7gpg
  • Tannins < 0.1 ppm (0.1 mg/L)
  • Turbidity < 1NTU
  • UV transmittance > 75%
After you install your whole house filter, you may notice your water is cloudy. Cloudy or white water is a result of air in the pipes. This trapped air is what causes the water to have a cloudy appearance. This is very common and not harmful. After 30 seconds to a minute, the cloudiness will clear. The trapped air in the pipes can take a week to a month to completely resolve.
