In most cases, your RO system will come with installation instructions, but we provide general instructions that will provide details on installing a Reverse Osmosis system. Under-sink RO (reverse osmosis) systems are typically installed beneath a kitchen sink or a similar area where they are easily accessible for maintenance and can provide purified water directly to a dedicated faucet. These systems are designed to fit in relatively small spaces and attach to existing plumbing under the sink.

Looking at cost alone, RO systems generally cost less than 30-cents per day to own and operate for a family of four. From a cost-savings perspective, since most Americans spend HK$799.31/year on bottled water translating to HK$3,197.25/year for a household of four. An RO system would save nearly HK$2,397.94/year as it operates for roughly HK$799.31/year. Environmental impact of bottled water should also be considered.

The number crunching doesn’t reveal anything about the health benefits of RO. Reverse Osmosis systems can remove harmful contaminants such as pesticides, fluoride, chlorine/chloramines, lead and arsenic.

No, reverse osmosis systems are generally not noisy. The main components, such as the membrane and filters, operate quietly. However, you may hear some noise during the water filtration process, like the sound of water flowing or a faint hum from the system's pump. Overall, the noise level is minimal and should not be a significant concern.

Non-air gap faucets tend to be quieter thank air-gap faucets. Non-air gap faucets make no gurgling sound since the drain line from the RO membrane flows directly into the sink drain line. Learn more about the difference between “Air Gap” and a “Non-Air Gap” faucet.

If you hear other sounds, such as a “hissing” noise, immediately call your local water treatment professional as there may be a problem with water pressure, the air gap or a leak.

Yes, reverse osmosis (RO) water is considered safe to drink. RO systems are highly effective at removing a wide range of contaminants from water, including sediment, chemicals, heavy metals, and dissolved solids. The RO membrane acts as a barrier, allowing only pure water molecules to pass through while blocking impurities.

The removal of contaminants through RO filtration helps improve the overall quality and safety of the water. It can significantly reduce the presence of harmful substances, such as pesticides, fluoride, chlorine/chloramines, lead, arsenic and other potential contaminants.

However, it's important to note that while RO filtration provides a high level of filtration, it may not remove all types of contaminants. Bacteria and viruses are better addressed through ultraviolet water disinfection.

Overall, RO water is considered safe for drinking and can provide clean, great-tasting water for your daily consumption.

RO filtration is effective at removing various contaminants, including minerals, from the water. While minerals like calcium, magnesium, and potassium are essential for our health, they are primarily obtained through food rather than water. Our bodies can absorb minerals from food more readily than from water, especially when they are in an inorganic state. Drinking RO-filtered water does not pose a risk of mineral deficiency because the minerals in water are not the primary source for meeting our mineral requirements. A well-balanced diet provides the necessary minerals for our bodies to remain healthy.

Typically, for every gallon of clean, filtered water produced by an RO system, around 3-4 gallons of water are discarded as waste. This is because the RO process uses water to "wash" away impurities, and the rejected contaminants, along with some water, are flushed out of the system.

While the water waste may seem significant, it's important to consider the trade-off for obtaining purified water. The focus is on removing contaminants and ensuring the quality of the water you consume. Learn more on this topic. 

Deciding whether to install a whole-house reverse osmosis (RO) system depends on your specific needs and circumstances. But generally we don't recommend whole-house RO system.

Consider the following factors:

1. Cost: Whole-house RO systems are typically more expensive upfront, considering the larger capacity and installation requirements. However, long-term cost savings may be achieved by eliminating the need for individual filters at each point of use.
2. Space and Installation: These systems require adequate space for installation, including space for storage tanks and plumbing modifications. Ensure you have enough room and assess installation feasibility in your home.
3. Water Waste: RO systems generate wastewater during the filtration process. The volume of wastewater produced to provide purified water for an entire home could be significant, so you should consider the environmental impact and potential water usage implications.
4. Maintenance: Whole-house RO systems require regular maintenance, including filter replacements and system sanitization. Ensure you are willing to commit to the necessary maintenance tasks.

Ultimately, it is recommended to consult with your local water treatment professional to assess your water quality, specific needs, and budget before making a decision about installing a whole-house reverse osmosis system.
