Installation, Capacity, and Filtration Specs
Installation Type
The Express Water ROALK10D is an under-sink system designed for permanent installation. You must connect it to your plumbing under the cabinet. It includes an emergency leak stop detector to shut off water flow if moisture is detected. In contrast, the AQUA TRU is a countertop unit. It plugs into any standard outlet and requires no plumbing or drilling. You simply fill the tank with tap water, and purified water dispenses into the glass carafe. If you want a portable solution without tools, the countertop design is the clear choice for your kitchen counter.
Daily Capacity
Capacity determines how much purified water you can get per day. The Express Water system produces 100 gallons per day. This high output supports household needs for drinking, cooking, and ice. The AQUA TRU does not list a specific daily production rate in its specifications. It relies on a glass carafe that you fill manually. While convenient for small amounts, it lacks the high-volume output of the under-sink unit. If you need large quantities of water for a family, the 100 GPD rating of the Express Water model offers significantly more capacity.
Filtration Stages
Filtration stages define the number of steps water takes to become pure. The Express Water unit uses a 10-stage process. This includes reverse osmosis and an alkaline filter that adds minerals like calcium and potassium back into the water. The AQUA TRU uses a 4-stage system. It includes pre-carbon, reverse osmosis, and VOC carbon filters. Both remove contaminants, but the Express Water offers more stages and mineral addition. The AQUA TRU focuses on core purification without listing mineral enhancement in its standard stage count.
Certification
Certification provides independent verification of performance claims. The AQUA TRU is tested and certified to NSF standards by IAPMO. This confirms it removes specified contaminants like microplastics and fluoride. The Express Water data lists removal of up to 99.99% of various contaminants but does not explicitly mention NSF certification in the provided specifications. For buyers who prioritize third-party verified standards, the certified status of the AQUA TRU is a distinct advantage. You should check the specific NSF standards applicable to your local water quality concerns.
Physical Design
Physical design affects where the unit fits in your kitchen. The Express Water system measures 17 inches in height, 15 inches in length, and 5 inches in width. It weighs 27 pounds and sits under the sink. The AQUA TRU is more compact, measuring 13.5 inches in height, 5.25 inches in length, and 1.5 inches in width. It weighs 14.7 pounds. The smaller footprint of the AQUA TRU makes it easier to place on a counter without taking up much space. It is also lighter and easier to move if needed.
Choose the Best RO System for You
Renters needing no installation
You choose this unit because it requires no plumbing or drilling. It sits on your counter and plugs into any standard outlet. The 4-stage filtration removes microplastics and fluoride. You get purified water in a glass carafe without modifying your kitchen space or dealing with complex setup tasks.
Homeowners wanting high capacity
You select this under-sink system for its 100 GPD capacity and 10-stage filtration. It connects directly to your plumbing for on-demand water. The alkaline filter adds minerals like calcium and potassium. You benefit from a built-in leak detection sensor and a customizable design that supports additional filtration attachments.
Users prioritizing mineral content
You pick this model because it features an alkaline filter with active mineral technology. It adds calcium, potassium, and magnesium to your water. The 10-stage process removes up to 99.99% of contaminants while enhancing taste. You get a permanent under-sink solution that automatically refills your storage tank.
