Who it fits
Good fit for
This system suits families or offices needing reliable, high-volume water. The 90 GPD rating supports multiple users without long wait times. Its WQA certification appeals to those prioritizing verified contaminant removal. The under-sink design fits standard cabinetry, making it ideal for kitchens with space constraints. If you want a durable, US-assembled unit with certified filters, this model meets those needs. It is best for users who prefer a straightforward, high-performance filtration solution without complex digital controls.
Who should skip it
You should look elsewhere if you need a countertop unit, as this model is strictly for under-sink installation. It lacks a permeate pump in the base configuration, which may limit efficiency in low-pressure areas unless you select the specific variation that includes one. If you require alkaline remineralization, the standard 5-stage model does not include this feature; you must choose the 6-stage alkaline option. It is also not suitable for those seeking a compact, portable filter due to its 25-pound weight and fixed plumbing requirements.
Verdict: The APEC Water RO-90 is a robust, high-capacity system for households needing verified contaminant removal. Its WQA certification and 90 GPD output make it a practical choice for busy kitchens.
Key specs explained for RO-90
Capacity (GPD): 90
This rating indicates the system produces up to 90 gallons of purified water per day. This high output suits households with significant daily water usage, such as large families or those who cook frequently. It ensures you do not need to wait long for the storage tank to refill. When comparing systems, higher GPD values generally mean faster replenishment during peak demand periods.
Filtration Stages: 5
The unit employs a five-stage filtration process to treat your water source. Each stage targets different types of contaminants, starting with sediment and ending with refined taste. This multi-step approach ensures thorough cleaning before the water reaches your faucet. When shopping, compare this to simpler three-stage units, as more stages typically provide a higher level of purification for complex water quality issues.
Certification: WQA Gold Seal
This certification verifies that the filters meet specific standards for contaminant reduction. It confirms the system removes up to 99% of impurities like lead, arsenic, and fluoride. This independent testing provides assurance regarding the safety and performance claims made by the manufacturer. When evaluating options, look for similar third-party certifications to ensure the product delivers on its health and safety promises.
Design: Under sink
This system is engineered to fit beneath your kitchen sink, keeping the countertop clear and uncluttered. It requires a dedicated space with access to cold water and a drain line. This installation type is ideal for homeowners who want a permanent, integrated solution rather than a portable unit. When comparing, consider the available cabinet space and plumbing access in your kitchen layout.
Design and build details
The APEC Water RO-90 is designed for under-sink installation. The listing describes the unit as a 5-stage reverse osmosis system. This layout fits standard cabinetry beneath your kitchen sink. The physical dimensions are 16 inches in length, 5.25 inches in width, and 17.5 inches in height. These measurements ensure it occupies minimal space while providing ample room for the internal filtration components. The system weighs 25 pounds. This weight suggests a sturdy build that remains stable once installed, reducing the risk of movement or vibration during operation.
The finish includes a chrome faucet. According to the listing, the faucet is lead-free, which is a critical safety feature for drinking water applications. The unit also uses JG high-grade tubing with quick connect fittings. These fittings are designed for secure, leak-free connections, simplifying the installation process for you. You do not need specialized tools to attach the tubing, as the quick connect design allows for a firm seal with simple pressure. The chrome finish on the faucet is durable and easy to clean, maintaining a clean appearance in your kitchen.
The system operates with a maximum feed water pressure of 85 psi. This specification indicates the unit is built to handle standard residential water pressure levels. It ensures consistent performance without requiring additional pressure boosting in most homes. The compact design allows for easy access to the filter stages for routine maintenance. You can replace the filters without removing the entire unit from under the sink. This practical design choice saves time and effort during filter changes, ensuring your water remains clean with minimal disruption to your daily routine.
Setup and everyday use
The APEC Water RO-90 is designed for under-sink installation, requiring space within your cabinetry. The unit measures 16 inches in length, 5.25 inches in width, and 17.5 inches in height. It weighs 25 pounds, so you need a sturdy shelf to support it. The system includes JG high-grade tubing and quick-connect fittings. These components allow for secure connections that help prevent leaks during setup. You connect the unit to your existing water supply line. The system operates with a maximum feed water pressure of 85 psi. This specification means you should check your home’s water pressure before installation to ensure it falls within the safe operating range. If your pressure is too high, you may need a pressure regulator. The system comes with a 100% lead-free chrome faucet. You install this faucet on your countertop or sink deck. This provides a dedicated point for dispensing purified water. Daily use involves turning on the faucet to access clean water. The 90 GPD capacity ensures you have ample supply for cooking and drinking. The five-stage filtration process removes impurities as water passes through the system. You benefit from unlimited ultra-fresh water without handling heavy bottles. The large super capacity filters reduce the frequency of changes. This feature minimizes maintenance tasks over time. The WQA Gold Seal certification confirms the system meets specific performance standards for contaminant removal. You can trust the output quality for your household needs.
Check space and pressure first
Before you buy the APEC Water RO-90, verify your sink space. The unit measures 16 inches long and 17.5 inches high. You must ensure your cabinet can accommodate these dimensions and support the 25-pound weight. Check your water pressure, as the system requires a maximum feed pressure of 85 psi. If your pressure is lower, you might need a booster pump, which is not included. Consider the filtration stages. This model uses a standard 5-stage setup. You may want to explore variations like the 6-stage alkaline or the version with a permeate pump for higher efficiency. Filter changes are part of regular upkeep. The listing notes large super capacity filters, which should reduce change frequency compared to smaller units. Ensure you have the necessary tools for under-sink installation. This system sits alongside other high-capacity options in the Reverse Osmosis Systems guide. It suits those prioritizing high output and certified contaminant removal over compact designs.
Check before you buy
- Measure your under-sink cabinet dimensions carefully.
- Confirm water pressure is under 85 psi.
- Decide if you need a permeate pump.
