Specifications side by side

WECO Reverse Osmosis Systems Compared

WECO’s lineup separates into two distinct categories based on your space and volume needs. The TINY-150ALK Compact RO System stands out for tight spaces. Measuring just 5.5 by 9 by 15 inches, this portable unit suits RVs or small kitchens where every inch counts. It delivers efficient filtration without demanding a large footprint under your sink.

For larger demands, WECO offers light commercial models. The HydroSense Light Commercial RO with UV provides sterilization for robust purification, weighing 70 pounds and measuring 15 by 34 by 20 inches. The MX-350 Alkaline RO System prioritizes high volume and pH control. Measuring 10 by 22 by 18 inches, it fits buyers who need more output than a standard residential system provides.

Where WECO Fits Your Needs

WECO’s range spans from ultra-compact to light commercial systems. The TINY-150ALK measures 5.5 by 9 by 15 inches, making it ideal for RVs or small kitchens. The MX-350 Alkaline RO System offers higher volume with alkaline filtration for large residential or light commercial use. The HydroSense model adds UV sterilization for robust purification. You will find no standard residential tank-based systems in this list. The selection focuses on space-saving or specialized commercial outputs. Choose the TINY-150ALK for tight spaces. Select the MX-350 or HydroSense for higher flow or UV needs.

How to choose the right WECO RO system

1. Check physical dimensions first

   Measure your available space before buying. The TINY-150ALK measures 5.5 by 9 by 15 inches, fitting easily into tight cabinets or RVs. Larger units like the HydroSense system require more room. It stands 34 inches tall and is 20 inches deep. Verify your clearance height and depth. A compact design ensures the unit fits without blocking other storage areas. Precise measurements prevent installation failures and ensure you select a system that physically fits your kitchen or utility area.

2. Match filtration stages to needs

   Consider the number of filtration stages required for your water quality. The TINY-150ALK uses a 4-stage filtration process. This setup provides essential purification in a smaller footprint. More complex water issues may demand additional stages or specialized filters. Check the stage count to ensure adequate contaminant removal. A higher stage count often means better taste and safety. Align the filtration complexity with your specific water concerns. This ensures the system removes the pollutants you care about most.

3. Select design for your space

   Choose a design that matches your installation environment. The TINY-150ALK features a portable design suitable for mobile homes or temporary setups. Other models are built for permanent light commercial use. Portable units offer flexibility but may lack the robustness of fixed installations. Permanent systems provide stability for high-volume daily use. Decide if you need mobility or a fixed, heavy-duty unit. Your choice depends on whether you move frequently or stay in one location. This decision impacts long-term satisfaction and usability.

4. Evaluate weight for installation

   Consider the weight of the system for your installation capability. The HydroSense model weighs 70 pounds. This significant weight requires a sturdy floor and potentially professional installation. Lighter units are easier to handle and move. Heavier systems often include larger tanks and pumps. Ensure your floor can support the load. Plan for the physical effort required to position the unit. Weight affects both installation difficulty and long-term stability. Choose a weight class that matches your strength and support structure.

5. Identify specialized filtration features

   Look for specific filtration features like UV or alkaline filters. The HydroSense includes UV sterilization for added safety in commercial settings. The MX-350 features an alkaline filter to balance pH levels. These features address specific water quality concerns. UV kills bacteria, while alkaline filters improve taste and mineral content. Determine if you need these specialized additions. Standard RO filters remove contaminants, but extra stages target unique issues. Select the features that align with your health and taste priorities.
