Reverse Osmosis & Water Filtration
Understand your water, the filtration process, and what an RO system can do.
1. What is reverse osmosis (RO)?
Reverse osmosis is a water filtration process that uses a special membrane to help remove dissolved impurities from water. It can reduce contaminants such as dissolved salts, certain heavy metals, and other unwanted substances, providing cleaner and better-tasting drinking water.
2. How does a reverse osmosis system work?
Water passes through several filtration stages. The sediment filter removes dirt, rust, and sand, while carbon filters help reduce chlorine, odors, and certain chemicals. The RO membrane then separates many dissolved impurities from the water. Depending on the model, additional filters may improve the taste or add minerals before the water reaches your drinking faucet.
3. What contaminants can reverse osmosis help reduce?
Reverse osmosis can help reduce many dissolved contaminants, including lead, arsenic, fluoride, nitrates, and excess dissolved salts. A properly designed and maintained RO system may also provide a barrier to certain microorganisms. Actual performance depends on membrane quality, feed-water conditions, system configuration, and maintenance.
4. Can I use a reverse osmosis system with deep-well water?
Yes. Many RO systems can operate with deep-well water, and customers commonly use this type of water source. However, deep-well water can contain varying levels of iron, hardness minerals, and other impurities. We recommend checking your water conditions before installation to determine whether additional prefiltration is needed.
5. What is TDS?
TDS stands for Total Dissolved Solids. It refers to the combined amount of dissolved substances in water, including minerals and salts. TDS is usually measured in parts per million (ppm). A TDS meter helps monitor dissolved-solids levels, but it cannot identify individual contaminants or determine whether water is microbiologically safe.
6. Does reverse osmosis remove beneficial minerals?
RO filtration reduces many dissolved minerals, including calcium and magnesium. Selected CrystalTap systems include mineral or remineralization filters that can add certain minerals back to the purified water to improve its taste.
7. Is reverse osmosis water suitable for drinking and cooking?
Yes. Water from a properly installed and maintained RO system can be suitable for drinking, cooking, preparing beverages, and other everyday household uses, provided the source water and finished water meet applicable drinking-water standards.
8. Is reverse osmosis the same technology used in water refilling stations?
Many water refilling stations use reverse osmosis as part of their purification process. CrystalTap brings similar core filtration technology into a compact household system, allowing you to produce purified water at home without relying entirely on water deliveries.

Products & System Selection
Compare capacities, configurations, and the features that fit your space.
9. What is the difference between 100 GPD and 400 GPD?
GPD means Gallons Per Day and indicates a system's rated daily water production capacity.
A 100 GPD system is generally suitable for regular household drinking and cooking needs. A 400 GPD system has a higher rated production capacity, making it suitable for households or small businesses that require more purified water.
Actual output depends on water pressure, temperature, membrane condition, and other operating factors.
10. How do I choose the right CrystalTap RO system?
Choosing the right system depends on your household size, daily water consumption, water source, available installation space, and preferred features.
Our team can help you compare models and recommend a suitable system based on your requirements.
11. What's the difference between a tank-type and tankless RO system?
Tank-type systems store purified water in a pressure tank so it's available when you open the drinking faucet.
Tankless systems produce purified water on demand and generally occupy less storage space. Their dispensing performance depends on the system's capacity and operating conditions.
12. Do CrystalTap systems require electricity?
Most CrystalTap RO systems use an electric booster pump to maintain the pressure needed for filtration. Some models also include electronic monitoring features.
Power requirements depend on the model. Our team can explain the specifications before installation.
13. Does an RO system take up a lot of space?
Our systems are designed for under-sink installation. Tank-type units require space for both the filtration assembly and storage tank, while compact tankless models generally require less cabinet space.
We recommend checking the available space before choosing a system.
14. Can CrystalTap RO systems be used in offices or small businesses?
Yes. Depending on the model and daily water requirements, CrystalTap systems can be used in homes, offices, small restaurants, and similar establishments.
For businesses requiring larger volumes of water, our team can recommend a suitable capacity.
