Health Benefits Of Drinking and Using Filtered Water 

AquaOx is the perfect solution for keeping you and your family healthy – inside and out – by filtering out many of the contaminants that you drink, absorb through showering and washing, and breathe through the vapors from showering, running water, and more. 

  • Drinking – Drinking unfiltered water that contains contaminants can cause you to ingest bacteria and other harmful substances that lead to illness. Carbon-based filters for refrigerator ice machines are magnets for bacteria if they are not changed regularly. An AquaOx whole-house filtration system eliminates the risk of using ice machine filters. 
  • Showering/Washing – Showering and washing your hands exposes your skin to harmful contaminants. What’s more, the longer you shower or wash, the more chlorine you absorb because warm water enlarges your skin’s pores, facilitating absorption. This means showering in chlorinated water is much more dangerous than drinking the same water. In fact, while showering, your body absorbs 6 times the contaminants it does when you drink 8 glasses of water.
  • Breathing – Showering and running water causes chlorine and other harmful synthetic chemicals to become gaseous, making them easy to inhale.  Even the simple act of opening a dishwasher just after a completed washing cycle poses threats to your health. At this time, toxic chlorine and cancer-causing Disinfectant Byproducts (DBPs) are released into the air. Once inhaled, these chemicals enter the blood stream directly—without the partial filtering effect of digestion.
  • Food Preparation – Washing fruit, vegetables, and meat as well as watering your home vegetable garden has the potential to spread contaminants to your food.

Q: Can AquaOx handle the size of my home?

 Q: How often do I replace the filter?

A: The AquaOx will last the average family of four 20+ years without any replacement filters or maintenance. You pay once and enjoy. 

Q: Is there any routine maintenance?

A: No! You simply set it and forget it.

Q: Can this system be used with a water softener?

A: Yes. You will install the AquaOx before the water softener system so all sediments and contaminants get filtered out before it goes to the softener. This will also increase the life of your water softener.

Q: Do I have to hire a professional to install the AquaOx system?

A: If you are a handy DIY kind of person, the AquaOx simply has an in and an out connection. Cut your pipes, connect the lines and turn it on. Of course, if it makes you feel better or you enjoy kicking back on your couch, then by all means you can hire a local plumber and they’ll install it as well. 

Q: Does the AquaOx take out minerals or affect pH?

A: The AquaOx leaves all the good stuff in your water (minerals) so that you get a great tasting glass of water and know you aren’t depriving your body of positive things. Rest assured that we remove all the bad stuff during this process.

Q: How much of the harmful elements does it eliminate?

A: It removes heavy metals, chlorine, tthms, VOCs, hydrogen sulfide and many other harmful elements that affect your skin hair and other systems of the body. 

Q: Where is the water filter installed in the house?

A: The AquaOx house filter is installed on the main water line coming into the house. It can be put in a garage, closet, crawl space, attic or anywhere on the main water line. It just needs to be protected from freezing. 

Q: What's the maintenance on a whole house filter system like AquaOx?

A: There is very little maintenance for the AquaOx. All that needs to be done is the timer for the backwash needs to be set for the correct time. If the power was to go off, the clock would have to be set to the correct time again. About once a month the pre-sediment filter will need to be flushed which takes about 2 seconds. 

Q: How do I clean a whole home water filter?

A: The AquaOx has a self-cleaning backwash which takes place every 4 days. No manually cleaning is necessary.
