Rated 5 out of 5 by from now fantastic tasting water with no chlorine smell semi difficult to install, used the combined picture on website to create the pipe interconnect. Except for having to wing the install, it works great.

Rated 5 out of 5 by from Great product, as advertised. No issues so far!! We purchased the OptimH2O Whole House filter with Descaler. Installed a few months ago and the filter works great. We immediately noticed a difference when showering and no scale on the appliances. Our previous water wasn't terrible, but we had semi hard water and this solved the problem and gives us peace of mind out of every faucet. One concern was around water pressure after install, as I read some reviews that it drops. We have a large home, 4 bds 3.5 bath, 3200 sq ft, and the water pressure holds up. Great product, easy to setup, and performs great. I'd highly recommend.

Rated 5 out of 5 by from Great tasting water PH dropped to normal range, chlorine is gone & Hard-water significantly reduced. Installation was fine we made a easy bypass and drain to help with future filter changes. Water is delicious and best part is we can take it from any tap in the house. Didn’t take long to see the difference on the test strips. After a week everything seemed to be settled and great. Only recommended change would be the black bushings that come with the system had a hard time to keep them from leaking. Had to purchase another set to finally get the leaking to stop.

Rated 5 out of 5 by from OptimH2O® Whole House Filter with Descaler & UV Performing as it should. We kept tropical fish and they died before we could transition from old filter system to Aquasana. Based on water testing kits since installation, our water is completely matching the best results on the test strips. The units sent to us by Aquasana were very well packed and protected. After units installed, everything works as per instructions and brochures. As advice, these units need 5 to 6 linear feet of space per photo by Aquasana. Our plumbers had 33 inches of space to work with and they did it and they were paid extremely well to do it. We have had whole house water filtration since moving into this house 38 years ago. Whole house is the only way to go and many benefits to the house beyond excellent tasting coffee.

Rated 5 out of 5 by from I absolutely love clean, pure water! The plumber did a fantastic job, and installed bypass valves as extra security. We purged the hot water heater, emptied the ice makers, power cleaned the washing machine and dishwasher. I told the plumber I wanted the "pretty" water everywhere. I can't even describe the multiple benefits-the coffee maker doesn't cloud up, the dishes are cleaner than ever, the soft water is silky (I forgot how lovely it would be.) Overall three thumbs up. I've bragged on the system to anyone who will listen.

Rated 5 out of 5 by from Aquasana OptimH2O Easy to install. Definitely can taste the water difference.

Rated 5 out of 5 by from So far so good! Purchased this set up with the water conditioning system, UV protection and RO system under the sink about 2 weeks ago. Aquasana recommended a good plumber in my area that has installed about 100 of these which was very helpful. Installation took our plumber about half the day, and another couple hours for the RO system under the sink. Overall I am very happy with this system, water pressure decreased very very slightly but nothing even worth complaining about. The RO system under our sink has led us to not buy anymore bottled water which is nice as well. This system does not give that slippery/oily water feel like a salt water conditioner would which is fine because there is no backflushing and regeneration with this system (save money on your water bill). NO MORE TOILET RINGS! We have 4 toilets in our home so not having to scrub the toilets every week to get rid of the toilet rings was just icing on the cake!

Rated 5 out of 5 by from So far loving it! Water taste great. Took plumper a few hours to complete. Didn’t hurt water pressure

Do these systems remove flouride?

Asked by: kmcd
Hello,   Thank your for your interest in Aquasana. The Whole Home system does not remove fluoride or arsenic. Both require Reverse Osmosis to be removed/reduced from water. We do offer a Point of Use Reverse Osmosis for your drinking water, and many of our Whole Home customers purchase it in combination.   You may read more about our Reverse Osmosis system at: https://www.aquasana.com/drinking-water-filter-systems/reverse-osmosis-claryum If you are interested in a system, please call 866.662.6885 or e-mail sales@aquasana.com and a representative will be happy to discuss your needs and options.   Thank you,   Aquasana Support

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 8.5 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 sanitizes up to 99.99% 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 99.9% 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 99.99%. The Aquasana UV Filter delivers a minimum of 30 mJ/cm2.
UV filtration typically offers a 4-log reduction (99.99% sanitization) for both bacteria and most viruses. UV filtration is more effective and more eco-friendly than chemical disinfection processes at destroying a wide range of viruses.
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%
