APEC vs Aigerri: Key Differences
installation type
APEC Water offers an under-sink system that requires plumbing connections and drilling for faucet installation. It includes an installation kit and uses quick-connection fittings for DIY setup. Aigerri is a countertop unit that needs no plumbing, drilling, or professional help. You simply plug it in and add water to the feed tank. This makes Aigerri ideal for renters or spaces where permanent modification is not allowed. APEC is better for homeowners seeking a permanent, integrated solution.
filtration stages
Both systems use five-stage reverse osmosis filtration to remove impurities. APEC Water includes a standard five-stage setup with options for alkaline or UV upgrades. Aigerri includes UV technology as a standard part of its five-stage process. The UV stage provides an additional layer of disinfection against bacteria and viruses. APEC relies on its multi-stage membrane and carbon filters for purification. Aigerri’s integrated UV adds a distinct sanitization benefit without requiring a separate upgrade kit.
pure to drain ratio
Aigerri specifies a 5:1 pure-to-drain ratio, meaning it produces five gallons of purified water for every one gallon of wastewater. This efficient ratio helps reduce water waste during the filtration process. APEC Water does not list a specific pure-to-drain ratio in its published specifications. Without this data, you cannot compare the water efficiency of the APEC system directly. Aigerri’s stated ratio offers a clear advantage in water conservation metrics for daily use.
capacity
APEC Water provides a capacity of 50 gallons per day (GPD) through its under-sink design. This rate supports high-volume household needs. Aigerri uses a 5L feed water tank and a 2L purified water tank. It claims up to 529 gallons of purified water under specified conditions. APEC does not list a total tank capacity or specific gallon count for its storage tank. APEC’s 50 GPD rate is a standard metric for continuous flow, while Aigerri’s tank-based approach limits immediate output volume.
design
APEC Water is a white, under-sink unit measuring 5.25 by 15.5 inches, with a height of 17 inches. It weighs 24.9 pounds and fits behind kitchen cabinets. Aigerri is a portable countertop device, white in color, measuring 13 by 13 inches with a height of 3 inches. It requires about 22 inches of vertical clearance when opened. APEC is built for hidden, permanent installation. Aigerri is designed for flexible placement on counters, islands, or in RVs.

The system includes a UV stage for extra purification. You can move it easily if you relocate your workspace.
Users prioritizing water efficiency
The Aigerri system features a 5:1 pure-to-drain ratio. This means it produces five times more purified water for every gallon of wastewater. This is more efficient than standard under-sink models. It helps reduce water waste during the filtration process. The separate tanks allow for convenient daily use without constant plumbing.
Buyers wanting added UV protection
The Aigerri model includes a UV filtration stage. This adds an extra layer of protection against bacteria and viruses. The APEC system relies on five mechanical stages. If you want additional disinfection, the UV technology is a key advantage. This makes the Aigerri suitable for areas with questionable water quality.
