What Are Air Gap and Non-Air Gap Faucets for Reverse Osmosis?
When it comes to getting clean drinking water in your home, reverse osmosis (RO) systems are a popular and highly effective choice. These systems work by forcing water through a semi-permeable membrane, removing contaminants and delivering purified water to your faucet. However, an essential component of an RO system is the type of faucet you use, and you have two main options: air gap and non-air gap faucets. Understanding the differences between these two can help you make the best decision for your home water filtration needs.
What is a Reverse Osmosis System?
Before diving into the details of air gap and non-air gap faucets, it's crucial to understand the basics of a reverse osmosis system. An RO system typically consists of several stages of filtration, including sediment filters, carbon filters, and the reverse osmosis membrane. The result is water that is free from contaminants such as chlorine, heavy metals, and other potentially harmful substances. RO systems are known for significantly improving sink water quality, providing a reliable source of clean drinking water for your household.
The Role of the Faucet in an RO System
The faucet is the final point where purified water is delivered to you, but it's more than just a simple tap. In an RO system, the faucet can also play a role in preventing backflow and making sure that the system functions efficiently. This is where the distinction between air gap and non-air gap faucets becomes important.
What is an Air Gap RO Faucet?
An air gap RO faucet is designed with a small air gap between the RO system and the drain. This gap acts as a physical barrier that prevents any potential contaminants from siphoning back into the RO system. Essentially, the air gap provides an added layer of protection for your clean drinking water.

How Does It Work?
When water flows through an air gap RO faucet, it passes through three tubes: the RO tube, the air gap tube, and the drain tube. The air gap tube creates a break between the RO unit and the drain, making sure that any wastewater from the RO system cannot be drawn back into the clean water supply. This feature is particularly important in preventing cross-contamination, which can occur if there is a blockage or issue with the plumbing system.
Advantages of Air Gap RO Faucets:
- Enhanced Safety: The primary benefit of an air gap faucet is its ability to prevent backflow contamination. This makes it a safer choice, particularly in areas where local plumbing codes require an air gap for RO systems.
- Compliance with Plumbing Codes: Many regions have specific plumbing codes that mandate the use of air gap faucets with reverse osmosis systems. If you live in such an area, choosing an air gap faucet ensures that your system is up to code.
- Protection Against Cross-Contamination: The air gap acts as a barrier against contaminants which helps to ensure that your purified water remains clean and safe for consumption.
Disadvantages of Air Gap RO Faucets:
Disadvantages of Air Gap RO Faucets:
- Complex Installation: Installing an air gap faucet can be more challenging than a non-air gap faucet. The process involves additional plumbing work, which may require professional assistance.
- Potential for Noise: The air gap creates a break in the water flow, which can sometimes result in a gurgling noise as water drains. This is normal but can be an annoyance for some users.
- Space Requirements: Air gap faucets require additional space under the sink to accommodate the three tubes, which may be a consideration if you have limited space.
What is a Non-Air Gap RO Faucet?
A non-air gap RO faucet, on the other hand, is a more straightforward option. It does not include the additional air gap feature, meaning the water flows directly from the RO system to the faucet and then to the drain. This type of faucet is more common in residential installations and is often favored for its simplicity.
How Does It Work?
In a non-air gap RO faucet, water is routed directly from the RO system to the faucet, with a single tube carrying the wastewater to the drain. This design eliminates the air gap, allowing for a more streamlined installation process.
Advantages of Non-Air Gap RO Faucets:
- Easier Installation: One of the main benefits of a non-air gap faucet is its ease of installation. Since it requires fewer connections and less plumbing work, it can often be installed by the homeowner without professional help.
- Quieter Operation: Unlike air gap faucets, non-air gap models do not produce the gurgling noise associated with the air gap tube, making them a quieter option for your kitchen.
- Space-Saving Design: With only one tube connecting the faucet to the RO system and drain, non-air gap faucets require less space under the sink. This can be particularly advantageous in smaller kitchens or homes with limited cabinet space.
Disadvantages of Non-Air Gap RO Faucets:
- Lack of Backflow Protection: The most significant drawback of a non-air gap faucet is the lack of built-in backflow prevention. Without the air gap, there is a higher risk of cross-contamination if there is a problem with the plumbing system.
- Not Code Compliant in Some Areas: Depending on where you live, local plumbing codes may require the use of an air gap faucet with an RO system. If you opt for a non-air gap faucet in such an area, you could be in violation of these codes.
Comparing Air Gap and Non-Air Gap RO Faucets
When deciding between an air gap and a non-air gap RO faucet, consider the following factors:
- Safety: If backflow prevention is a top priority, the air gap faucet is the clear winner. Its design ensures that your RO system remains protected from potential contamination, providing peace of mind.
- Installation: For those who prefer a simpler and quicker installation process, a non-air gap faucet is a more convenient choice. Its straightforward design eliminates the need for additional plumbing work, making it an attractive option for DIY enthusiasts.
- Local Plumbing Codes: Always check your local plumbing codes before making a decision. In some areas, the use of an air gap faucet may be mandatory for RO system installations. If this is the case, compliance with these regulations is essential.
- Noise and Aesthetics: If noise is a concern or if you prefer a sleek, minimalist design, a non-air gap faucet might be more suitable. The absence of the air gap tube results in quieter operation and a more streamlined appearance.
- Space Considerations: In homes with limited space under the sink, a non-air gap faucet can be a more practical solution. Its single-tube design requires less room, making it easier to fit into tight spaces.
