Who it fits

Key specs explained

Design: Countertop

This unit sits on your counter rather than under your sink. You do not need to drill holes or connect permanent plumbing lines. This makes it ideal for renters or those in apartments who cannot modify their kitchen layout. It also allows you to move the system to different rooms, such as an office or RV, as needed. You simply place it on a flat surface and plug it in.

Filtration Type: Reverse osmosis, UV

The system uses reverse osmosis to force water through a membrane that blocks contaminants. It adds UV purification to kill bacteria and viruses. This two-step approach provides thorough treatment of tap water. You get water that is free from physical impurities and biological threats. This combination is useful for ensuring safety, especially if you are concerned about microbial content in your source water supply.

Filtration Stages: 5

The water passes through five distinct layers of filtration media before reaching your tank. Each stage targets different types of impurities, from sediment to dissolved solids. More stages generally mean more thorough cleaning of the water. You benefit from a cleaner final product compared to single-stage filters. This multi-step process helps remove a wider range of contaminants for better taste and safety.

Pure to Drain Ratio: 5:1

For every five cups of purified water produced, one cup is sent to the drain. This ratio is higher than many traditional systems, which often waste more water. You generate less wastewater while producing the same amount of drinking water. This efficiency helps you conserve water resources. It is a practical feature for eco-conscious buyers who want to minimize the environmental impact of their water filtration habits.

Design and build details

The Aigerri unit features an off-white finish and a compact countertop footprint. According to the listing, the dimensions are 16.2 inches wide, 7.4 inches long, and 16.4 inches high. It weighs 13.9 pounds. This size allows it to sit on kitchen counters, islands, or office desks without taking up excessive space. You can place it in apartments, RVs, or homes where under-sink access is limited. The design is portable, meaning you can move it between rooms if needed. It does not require permanent plumbing connections. You simply fill the feed water tank and plug it in. The system includes a 5-liter feed tank and a separate 2-liter purified water tank. This layout separates raw and clean water, which helps maintain hygiene. The UV filtration stage adds an extra layer of protection against bacteria. The five-stage process combines PPC and RO membranes with ultraviolet light. This build quality targets users who want clean water without installing complex systems. The compact form factor fits modern living spaces well. You get flexibility in placement, whether for daily home use or temporary setups in offices. The unit’s dimensions ensure it stays stable on flat surfaces while providing easy access to water. The off-white color blends with most kitchen decors. This practical design supports convenient, on-demand purified water without renovation work.

Setup and everyday use

You do not need plumbing knowledge or professional help to set this unit up. The listing describes a plug-and-play design that skips complicated installations. You simply place the unit on a flat surface, such as a kitchen counter, island, or office desk. Then you fill the 5L feed water tank with tap water. After plugging the device into a standard electrical outlet, the system begins its filtration process. This approach makes it suitable for renters, RV owners, or anyone who cannot drill holes in their countertop.

Daily use involves managing two separate tanks. You fill the large 5L feed tank, and the system produces purified water that collects in a separate 2L purified water tank. The five-stage filtration, which includes UV purification, treats the water as it passes through the PPC and RO filters. You can expect up to 529 gallons of purified water from the included filters before needing replacements. The 5:1 pure-to-drain ratio means the system produces five parts clean water for every one part wastewater. This efficiency helps you conserve water while you drink. The compact design ensures it fits easily in small spaces without taking up too much room. You can move it between locations if needed, as it weighs 13.9 pounds. The process is straightforward: fill, plug, and wait for the purified water to accumulate in the storage tank.

Before you buy this unit

You should verify your electrical outlet proximity before purchasing. The unit requires a standard plug-in connection near your countertop. Ensure you have at least 22 inches of vertical clearance when the lid is open. You must also consider filter replacement costs. The listing mentions one PPC filter and one RO filter. You will need to purchase these replacements periodically to maintain the 529-gallon capacity. Check if your local water pressure supports the 5:1 pure-to-drain ratio effectively. Hard water may affect filter lifespan. This system fits well alongside under-sink models if you prioritize portability. It suits renters or RV owners who cannot install permanent plumbing. Unlike fixed systems, you move it as needed. Keep the 5L feed tank and 2L purified tank clean to ensure hygiene. Regular maintenance of the UV component is also necessary for effective purification.

Check before you buy

• Check for a nearby electrical outlet for plug-in use
• Verify 22 inches of vertical clearance for the open lid
• Plan for periodic PPC and RO filter replacements
• Ensure your water pressure supports the 5:1 drain ratio
