What this countertop purifier actually does
- Does the counter footprint fit under your upper cabinets?
- How often will you need to refill the pitcher?
- Does your tap water pressure matter for RO?
- Where will you plug it in on the counter?
The DREO Reverse Osmosis Water Filter Countertop is built for renters and small kitchens where plumbing work isn't an option. It filters out 99.9% of possible contaminants including PFOA, PFOS, chlorine and fluoride, and it meets NSF/ANSI 58 standards according to SGS testing.
It also self-cleans and comes with two autofill pitchers, so you can fill a glass or a pitcher while it runs. The 5L size means it takes up counter space, but you skip the under-sink install.
We'd consider this a practical pick if you want RO filtration without calling a plumber. It suits anyone who drinks a lot of water at home and wants a countertop unit with a filter life indicator and TDS readout.
What the $169.99 price means
At $169.99, this DREO countertop RO system comes in $22.17 below the typical price over the last 90 days. That's a 12% savings compared with the typical price over the last 90 days. The lowest price we've seen for this exact model is also $169.99, in its all-time window.
With a 4.4-star rating and 851 reviews, it's a well-used model. The price includes the two autofill pitchers and the initial filters, so you won't need to buy a separate starter kit.
We'd skip it if you're looking for a whole-house solution or already have an under-sink RO system. But for a rental or a temporary setup, the countertop design avoids plumbing and installation costs.

Room fit, filter care and running questions
This unit needs counter space near an outlet, and the 5L size means it won't disappear next to a toaster. The self-cleaning function helps reduce manual maintenance, but you'll still replace filters over time based on the filter life indicator.
Replacement filter prices and the interval for changes are not listed, so check those before buying if long-term cost matters. The 3 to 1 pure-to-drain ratio means for every 3 parts of pure water, 1 part goes to drain, which is typical for RO systems.
Clean the exterior with a soft cloth and keep the pitchers clean. The TDS display helps you see when water quality changes, but it doesn't replace the filter life indicator.
Who should skip this countertop RO system
If you need to filter water for a large family without refilling pitchers often, this 5L system may feel small. It's also the wrong fit if you already have a built-in RO system or if counter space is tight.
Finally, if you want a filter that doesn't produce any drain water, an RO system isn't the right category. This unit sends 1 part to drain for every 3 parts purified, so it's not a zero-waste option.
Before you buy, confirm the replacement filter price and how often DREO recommends changing them, since those running costs aren't listed here.
