About the System:
Our Universal Alkaline 5-Stage Reverse Osmosis System is a reliable solution for water purification and remineralization. It delivers approximately 3–6 gallons of purified water per hour and is ideal for homes with mild to hard water supplies (TDS above 100–300 ppm). This RO system removes over 220 hazardous contaminants and reduces fluoride by 90%–98%.

Fluoride Alert.
What to Expect
If your tap (source) water is around 300 ppm TDS, after the final stage (alkaline filter) you can typically expect 35–65 ppm TDS and a pH of around 8.5–9.
If you choose the RO system with a mineral post-filter, TDS will typically range from 25–55 ppm and pH around 8.0–8.5.
Important: For accurate results, testing should be done after 4–6 days of regular use.
RO System Dimensions: 14″ × 6″ × 6″
This RO system produces 1 gallon of purified water every 11–22 minutes, depending on the membrane’s GPD rating. The purification process is slow—water drips rather than flows—so we strongly recommend collecting water in advance (daily or every other day) to ensure it is always available.
Don’t be surprised: countertop RO systems purify water 8–10 times slower than standard water filters.
All RO systems divide water into two streams: purified water and wastewater. The typical ratio is approximately
1 part purified water to 2.4 parts wastewater, which is normal for reverse osmosis technology.
Inline Mechanical Shut-Off Timer
This optional inline mechanical timer is highly recommended when using a countertop RO system.
It automatically shuts off the water supply after a preset time, making it easy to fill containers without
worrying about overflows.
- Automatically stops water flow when your container is full
- Prevents spills and water damage
- Perfect for unattended or overnight filling
- No electricity or batteries required

I would highly recommend this RO to customers. It reduced the dissolved solid content in my apartment tap water from 350+ to 30 within 2 hours after installation. Good solution for those who are buying water from supermarket. This will save money and time.

I was actually buying water from local grocery store, it was 0.40 cents per gallon, not bad. Until one day I bought a TDS meter and realized that my RO from grocery was virtually the same as tap water. It even tasted like tap water, I was paying 40 cents a gallon for tap water, what a rip off. Then I went to Safeway. Their machine showed a TDS of less than 50 PPM and it tasted great, but cost 50 cents a gallon. Then their machine broke, and all they sold were 5 gallon jugs for $7.50. So I was paying over a dollar a gallon for drinking water. So in a little over 2.5 months I was paying about what this water filter cost.
If you buy this filter you for sure will need a TDS and PH meters. When you first start it up the TDS will be sky high until it flushes itself out and the timing on that depends on your water pressure. Start collecting water when it gets below 45 PPM. Seems like the longer you run this filter the lower the number gets and the better the water. But when you start it back up the numbers are high again for the first 20 minutes or so, I drain that off before I collect it.
Whatever you do, don’t ever drink your tap water no matter how good you think it is. I’m a retired chemist and let me tell you that there is no way to test your water for everything. Most water tests will only test the basic few parameters. For a wide spectrum of compounds you would need to spend thousands of dollars in various tests, and even then you could be contaminated with a new designer drug or something that will bypass the tests and they would never detect it. What you really want is RO water, but not with a TDS of zero, you want minerals added back. This system is the best I’ve seen, it will remove all compounds and minerals and then add back just enough to make it taste good and 100% safe.

I received this 5-stage countertop RO system as a gift, and it has exceeded my expectations in terms of water purification. It effectively reduces the TDS (total dissolved solids) from 750 to 60, ensuring a remarkable level of cleanliness. Initially, I had concerns about the pH level, as my pH reader indicated that the RO water was around 6-6.5. However, the customer service representative I contacted was outstanding. They promptly addressed my concerns by sending me an alkalizing filter and a pH meter, completely free of charge. After replacing the last filter with the one they provided, I noticed a definite increase in pH.
One of the advantages of this system is its compact size, taking up minimal space on the countertop. Additionally, the installation process is incredibly easy, and replacing the filters is a breeze. Considering the affordable price point, it offers exceptional value for achieving completely purified water. The taste of the water is fantastic, comparable to, if not better than, bottled water. I wholeheartedly recommend this RO system. Not only does it provide peace of mind by offering safer water compared to systems with under-sink tanks, but the company behind it also delivers a great buying experiencev

This is the perfect unit for a condo/apt – even for an aquarium!

I really love this system. I have been using it approximately for 1 week. It is very easy to connect to the faucet. I read the manual that test needs to be done after 20 gallon of water passing through the system. I was able to test today. Originally my tap water TDS was 340ppm, after filtration it’s 45 ppm, pH 8.6 is little higher then I expected (my target was pH 8.5-8.7) but I cool with it. I’m happy with purchase.

Here’s the harsh truth: nearly all septic companies just service tanks. They’re like quick-fix salesmen at a demolition convention. But Septic Solutions? These guys are unique. It all originated back in the early 2000s when Art and his family—just kids scarcely tall enough to lift a shovel—helped install their family’s septic system alongside a grizzled pro. Visualize this: three kids waist-deep in Pennsylvania clay, learning how soil permeability affects drainage while their friends played Xbox. “We never just dig ditches,” Art explained to me last winter, hot coffee cup in hand. “We learned how ground whispers truths. A patch of wetland vegetation here? That’s Mother Nature screaming ‘high water table.'”
