Understanding the 3-Stage Protection Map
The technical superiority of the HQUA system is found in its multi-layered filtration approach. The process begins with a heavy-duty sediment filter that acts as a shield for the subsequent stages, trapping dirt and rust. The second stage utilizes a compound KDF and GAC media, specifically designed to target heavy metals and prevent microbiological growth. The final stage uses high-density carbon block technology to polish the water, ensuring it is odorless and refreshing at every tap in your house.

Professional User Verdicts
Dramatic improvement in our water quality. The clarity is night and day, and the sulfur smell from our well is completely gone. Installation was professional-grade.
The monitoring gauges are fantastic. I love knowing exactly when my filters are starting to reach their capacity. Very sturdy build quality.
Highly recommend for anyone on city water who hates the taste of chlorine. It filters everything and doesn't affect our shower pressure at all.
Technical FAQ
How is RO water compared to bottled water?
Just as good or even better. We use the same technology as other major bottling plants use to filter water. RO systems purify water daily in your home which is fresher and healthier compared to water that has been sitting in plastic bottles.
How effective is Reverse Osmosis filtration compared to other methods?
RO is the most convenient and effective method of water filtration. It filters water by squeezing water through a semi-permeable membrane, which is equals to 0.00000004 inch! This is the technology used to make bottled water.
What is the WQA and what are the benefits of purchasing a certified system?
To receive WQA Gold Seal certification, a RO system must be constructed to meet strict public health standards and pass weeks of rigorous testing for material and parts safety, structural integrity, and contaminant rejection performance.
What is the size of the product, and if I move, can I remove the system?
The dimensions are 17.5"H x 15.5"L x 5.25"W, and the tank is 11"W x 15"H. This system is very easy to uninstall. Just close the water inlet needle shut off, take off the water inlet tubing, and take off the whole system in 5 minutes.
How often do I need to replace the filters?
Normally, you should change the cartridge every 6 months or up to 100,000 gallons. The maintenance cards, countdown timers and pressure gauges would help you remind the schedule.
