How to Choose the Right 800 GPD RO
-
Check the Design Type
You should verify whether the system uses a tank or tankless design. The Ecoviva RO800G Tankless 9-Stage RO eliminates the need for a storage tank. This saves valuable under-sink space. Tankless models also prevent stale water issues. You get fresh water directly from the membrane. If you have limited cabinet space, a tankless unit is the practical choice. It fits modern kitchens better than bulky traditional systems.
-
Compare Physical Dimensions
Measure your under-sink cabinet before buying. The Ecoviva E8 800 GPD Tankless RO measures 5 inches wide. This makes it the narrowest option on the list. It fits into tighter spaces than wider units. The Ecoviva RO800G is 6.5 inches wide. You must ensure your cabinet has enough width. Check height and length as well. Proper fitment prevents installation headaches later.
-
Look for Certification
You need to confirm the system holds valid certifications. The Ecoviva RO800G is NSF Certified. This verifies its performance and safety claims. Certified systems meet strict industry standards. You can trust the water quality results. The Ecoviva E8 does not list this certification in its data. If safety and verified performance are your priority, choose the certified model. Always check for published proof.
-
Review Filtration Features
Check what additional filters are included. The Ecoviva RO800G includes an Alkaline Filter. This stage adjusts the pH level of your water. It can improve taste and mineral content. The Ecoviva E8 does not mention this feature. You might need to buy alkaline filters separately. Consider if you want enhanced taste. This spec affects the final water profile. Choose based on your taste preference.
-
Assess Water Efficiency
You should check the pure to drain ratio. The Ecoviva RO800G has a 3:1 ratio. This means it produces three gallons of pure water for every one gallon wasted. This is efficient for daily use. The Ecoviva E8 lacks this stated ratio. You cannot verify its efficiency from the data. Lower waste saves water over time. Compare this spec to estimate long-term usage. Efficiency matters for environmental and utility reasons.
