How to Choose the Right System
-
Check Daily Output Capacity
You must match the gallons per day (GPD) rating to your household size. The 100 GPD model suits larger families needing quick access to filtered water. It provides double the output of standard units. Smaller households with moderate water needs can rely on the 50 GPD system. This tier offers dependable purification without requiring high volume. Verify the GPD number on the spec sheet to ensure the unit meets your daily usage requirements.
-
Verify Filtration Stages
Both models in this lineup utilize a five-stage filtration process. This configuration ensures thorough purification by removing contaminants through multiple layers. You should look for this specific stage count on the product attributes. The five-stage design provides consistent water quality across both capacity options. Do not assume all RO systems use the same number of filters. Confirm the five-stage specification to guarantee the level of purification you require for your drinking water.
-
Review Certification Status
Certification indicates that components meet specific safety and performance standards. The 100 GPD unit features NSF Certified components for verified quality. You should prioritize models with this certification for peace of mind. It confirms the materials are safe for contact with drinking water. Check the attributes section for this label before purchasing. The 50 GPD model provides dependable filtration but you must verify its specific certification details in the published data.
-
Assess Under Sink Fit
Both systems are designed for under-sink installation to save counter space. You need to measure your cabinet dimensions before buying. The 100 GPD unit measures 15 inches long and 5.25 inches wide. The 50 GPD model shares these exact width and height dimensions. Ensure your under-sink area can accommodate these specific measurements. Verify the length and width specs to avoid installation issues later. Proper fit ensures the system operates correctly without obstructing other plumbing.
-
Consider Installation Type
All Max Water RO systems listed are built for under-sink mounting. This installation type keeps the unit hidden and out of the way. You should confirm this mounting style matches your kitchen layout. Under-sink units typically require space behind the cabinet door. Verify the installation type in the product attributes. This ensures you purchase a system compatible with your existing plumbing setup. Avoid models requiring different mounting methods if you prefer a hidden design.
