What the Aigerri countertop filter is built to do
- Quick answer: a plug-in 5-stage RO and UV countertop purifier with a 5L feed tank and a 2L purified tank, no plumbing required.
- Best for renters, small kitchens, offices and RV owners who cannot or will not install an under-sink system.
You want cleaner-tasting drinking water without hiring a plumber or cutting into a supply line. This Aigerri unit sits on your counter and treats water in two tanks: a 5L feed tank you fill by hand and a separate 2L purified tank that holds the finished water.
The five-stage path combines a PPC filter, an RO membrane and UV treatment, so it handles both dissolved solids and the microbial side in one pass. Plug it in, add water, and it starts. That makes it a fit for apartments, offices, dorms and RVs where a permanent under-sink setup is not an option.
We'd consider it for a household that refills a pitcher or dispenser several times a day and wants the source to be a countertop appliance instead. The 2L finished tank is the practical limit to plan around, since that is what you pour from until the next cycle finishes.
What $249.98 buys and how the comparison works
At $249.98, this offer sits about $36.73 under the typical price over the last 90 days of $286.71. It also matches the lowest price recorded for this product in the all-time window, so there is no cheaper moment to wait for on that measure.
The number to weigh against that is the filter set, not just the box. The PPC and RO filters are rated for up to 529 gallons under specified conditions, and replacement pricing is not part of this listing. Before ordering, check what a replacement filter set costs and how often the brand expects you to change it, because that spend recurs for as long as you keep using the machine.

Space and counter fit
Closed, the unit measures about 16.1 inches, and it needs roughly 22 inches of vertical clearance once opened. Measure your cabinet overhang, shelf or upper cabinets before you commit, because a counter that looks clear in a photo can still leave no room for the lid to swing up.
The 5:1 pure-to-drain ratio means more of what you pour in comes out as drinking water and less goes to waste, which matters if you dislike tipping away a large share of every batch. Placement near an outlet on a kitchen island, tea table or office desk is the point of the design, so think about where the cord reaches and where the filled tanks are easy to lift.
Cleaning and tank care follow the brand's instructions, and both the feed and purified tanks are meant to be handled as removable parts. Keep the two tanks separate in daily use to avoid mixing raw and finished water.
When this countertop purifier is the wrong fit
Skip it if you expect to fill a large pot, a kettle or several bottles at once from a tap-like flow. This is a tank-fed appliance, and the 2L finished reservoir sets the pace of every pour.
Skip it too if you want the filtration hidden away under the sink and the counter left clear. This unit lives on the surface, so it takes up a defined footprint every day.
One last check before you buy: confirm the replacement filter part numbers and their price, since the ongoing cost of running this system is not stated here.
