Description
Basic portable countertop reverse osmosis
4-stage RO system with 75 or 150 GPD membrane and T33 carbon polishing
This compact countertop reverse-osmosis system connects to a compatible faucet or utility-water outlet without permanent under-sink installation. It combines sediment filtration, coconut-shell carbon, a high-rejection TFC membrane, and final T33 carbon polishing for drinking and cooking water.

Product purpose
Simple countertop RO purification without a storage tank or permanent plumbing
The system is designed for apartments, homes, offices, RVs, and temporary installations where an under-sink system is not practical. Purified water flows directly into a clean pitcher or container while the concentrate line drains into the sink.
Straightforward filtration
RO Purification + Carbon Polishing
Uses a classic four-stage arrangement without DI, alkaline, mineral, or specialty post-treatment cartridges.
Four filtration stages
Particle protection, carbon pretreatment, RO separation, and taste polishing
1
5-Micron Sediment
Helps capture rust, sand, dirt, and other suspended particles before they reach the carbon filter and RO membrane.
2
T28 Coconut-Shell Carbon
Helps reduce chlorine, taste, odor, and selected organic compounds that could affect membrane performance.
3
TFC RO Membrane
Helps reduce dissolved salts, hardness minerals, fluoride, nitrate, arsenic, lead, chromium, and many other dissolved constituents.
4
T33 Coconut Carbon
Provides final taste and odor polishing before the water is collected for use.
Key benefits
Affordable portable RO for everyday drinking and cooking water
Reverse-Osmosis Reduction
Helps reduce dissolved minerals, salts, metals, fluoride, nitrate, and other membrane-rejectable substances.
Two Output Options
Choose 75 GPD for standard output or 150 GPD for faster collection under suitable conditions.
Final Carbon Polishing
The fourth-stage T33 cartridge helps improve taste and reduce residual odor.
Portable Countertop Use
No storage tank, drain saddle, dedicated faucet, or permanent under-sink installation is required.
Multiple Adapter Options
Choose a standard kitchen, bathroom, garden/laundry, pull-down, or another supported connection.
Designed and Assembled in the USA
The current listing states that the complete system is designed and assembled in the United States.
Output expectations
Approximately one gallon every 11–22 minutes
Countertop reverse osmosis produces a slow purified stream by design. Actual output depends on water pressure, water temperature, source-water TDS, membrane condition, and flow-restrictor configuration.
Produces approximately one gallon in 22 minutes under suitable conditions, or about 2.5–3 gallons per hour.
Produces approximately one gallon in 11 minutes under suitable conditions, or about 5–6 gallons per hour.
The GPD rating is a standardized membrane rating, not guaranteed household output. Cold water, low pressure, high source TDS, clogged prefilters, and membrane age reduce production.
Reduction guidance
What the filtration stages may help reduce
Reduction performance varies with source-water chemistry, pressure, temperature, membrane condition, cartridge condition, flow, and maintenance. This system is intended for treated potable water.

Water-quality expectations
Final TDS depends on membrane rejection and source water
From source water near 300 ppm, the page gives an example of approximately 20–46 ppm after 4–6 days of regular use.
New carbon filters and the membrane require flushing before TDS, taste, and flow readings stabilize.
A fixed TDS result cannot be guaranteed. Actual output depends on source-water TDS, water pressure, temperature, membrane rejection, flow, and cartridge condition.
Optional mechanical timer
Helps stop water after a selected time interval
An optional inline mechanical timer can shut off the feed-water flow after the user-selected period. It may help reduce overflow risk when the required fill time is known.
A mechanical timer does not detect the water level and does not know when a container is full. Set the time conservatively, remain nearby until the correct fill time is established, and do not rely on it as an overflow sensor.
Filter replacement
Maintain according to usage and measured performance
Replace approximately every 12 months or up to 1,000 gallons, and sooner if flow, chlorine breakthrough, taste, or odor indicates exhaustion.
Replace approximately every 24 months or when measured membrane rejection declines below the desired level.

Great product wish I had purchased it earlier
I received this at the end of July 2020, and have been using it for all my drinking and cooking water. Out of the box, it was putting out water at 2ppm on a municipal water supply that was around 243 ppm. It’s currently January 2021, and that’s when I took the picture. It is still producing excellent water at 2 ppm.
It’s a one person/one cat household, but several times I have accidentally left it running all night long wasting gallons of water. So my usage is probably a normal three person family. Takes about 28 minutes to fill a gallon. I Just set a timer now so I don’t forget.
It is super easy to install, sometimes I’ll just leave it hooked up and use the bypass valve. But it’s stores neatly on the shelf above my sink when not in use. I will update this review before it’s time to replace the filter.
Well worth the money, it will save you hundreds of empty plastic bottles and lugging cases of water around, or buying filters that really don’t perform anywhere near the level that this filter does. My goal was to remove the poisonous fluoride & lead in my municipal water supply, and this gets that out along with nearly every other particulate matter. Cheers!

Works very slow , but it is ok…

I am genetically modifying plants and growing them via hydroponic (dwc) garden the PPM is a constant 23 ppm once you pump the first gallon or so through. If you are looking for a portable filter this is definitely the one. My water tests at around 240 ppm here at the house so my waste was about 3:1. The shipping was very fast.

Excellent unit. RO unit is truly an outstanding water filter option, especially considering its unbeatable price. I purchased this unit several months ago, and I occasionally check the ppm levels approximately once a month. During my last check, the ppm reading was an impressive 12. This level of filtration is truly remarkable. To ensure its continued performance, I do recommend investing in a TDS (total dissolved solids) pen. This handy tool allows you to monitor the effectiveness of the system over time and keep an eye on its ongoing performance. It’s a worthwhile addition to maintain confidence in the quality of the filtered water.

Yummy! MyAquaFilter Countertop RO unit is an excellent choice for those who are tired of constantly purchasing short-lived water filter pitchers for their fridge. However, there are a couple of minor improvements that could enhance the user experience. Firstly, I believe the hoses should be longer, as once the system is attached and in place, your faucet becomes somewhat restricted. Additionally, a true quick connect feature would be beneficial. When it comes to taste, the Countertop RO system delivers delicious water. Even if you leave it out overnight, the water retains its refreshing flavor and doesn’t develop the unpleasant taste that is often associated with other filtered waters. This is particularly noteworthy for those, like myself, who keep a glass of water on their nightstand and dislike the taste of water in the morning.In conclusion, while there are a few minor improvements that could be made, the Countertop Reverse Osmosis system is an ideal alternative to short-lived water filter pitchers. Its ability to consistently provide great-tasting water, even after sitting out overnight, makes it a worthwhile investment for anyone seeking a convenient and refreshing drinking water solution.
