Alkaline Replacement Water Filter Kit Review
Product Overview
If you are using a reverse osmosis (RO) water system, you may notice the water can taste flat and slightly acidic due to the intense filtration removing minerals. The Geekpure 10-inch Universal Inline Alkaline Replacement Water Filter Kit pH+ is designed to solve that. This filter raises your RO water’s pH to a balanced alkaline level, around 7.5 to 8.5, while adding essential minerals back in. It fits most 5 or 6 stage RO systems and improves water taste and health benefits by supplementing calcium, magnesium, sodium, and potassium ions.
This inline filter kit includes everything needed for easy installation, including quick fittings for different tubing sizes, clamps, and seal tape. It’s a practical upgrade to make your purified water more refreshing and nutrient-rich.

Why You Might Need an Alkaline Replacement Water Filter Kit
If your filtered reverse osmosis water tastes flat, slightly sour, or has no mineral content, this filter addresses those common pain points. RO systems are great at removing contaminants but also strip out beneficial minerals, which can leave water tasting bland and even slightly acidic with a pH of 5-6.
You might want to restore the natural mineral balance for both taste and health reasons. Also, if you want water that feels more refreshing and supports hydration with vital minerals like calcium and magnesium, adding an alkaline filter stage can help. It’s especially useful if your RO system doesn’t have an inbuilt remineralization step or if you want a straightforward upgrade.
First Impressions: What to Expect
When unboxing this Geekpure filter kit, you will find the alkaline filter itself plus all the accessories needed for quick installation. The filter is individually wrapped and sealed for freshness. The package includes quick fittings for both 1/4″ and 3/8″ tubing, fixed clamps, seal tape, and additional PE tubing pieces. This makes it compatible with a wide variety of standard RO setups.
One notable feature is the filter’s dimension—it measures 2 inches in diameter and 10 inches in length, fitting most 5- and 6-stage reverse osmosis systems. The build feels solid without being bulky, and the fittings snap into place firmly. You’ll want to flush the new filter for about 15 minutes before using it, as recommended.

Design & Build Quality
The Geekpure alkaline water filter is carefully constructed to provide long-lasting performance in an inline setup. The filter housing is made of durable plastic that feels sturdy but not heavy. It’s built to withstand usual household water pressure without leaks. Several users highlight the tight sealing and secure fit of the included quick fittings for both 1/4” and 3/8” tubing, which makes it adaptable to various RO plumbing configurations.
One user review mentions, “The filter came well-packaged and was easy to install without any leaks. The fittings snapped on nicely and held firm.” The individual wrapping and sealing also help preserve the filter’s effectiveness during storage.
The compact 10-inch length makes it a neat upgrade choice for slotting into existing RO systems, even if space is tight. Given its universal 1/4” NPT thread size, it’s designed to be compatible with a wide range of reverse osmosis filters, making it a smart choice regardless of your current stage count.
Real-World Performance
In practical use, this Geekpure inline filter noticeably affects the taste and feel of the water coming from reverse osmosis systems. After installing and flushing the filter as instructed, users report that their water becomes noticeably smoother and more refreshing. The slight metallic flatness or acidic tang common to RO water decreases thanks to the boosted pH and mineral content.
A homeowner shared an experience: “After installing this alkaline filter, my family noticed the water tasted fresher and more satisfying. Even my kids who don’t love plain water started drinking more. It really adds that natural mineral feel back to the water.”
The mineral blend includes calcium, magnesium, sodium, and potassium, all vital for hydration and overall body function. The filter provides these minerals in balanced proportions to adjust the pH and supplement the RO water with nutrients, enhancing both taste and health.
Maintaining the filter on a 3 to 6 month replacement schedule keeps the water consistently balanced and flavorful. The flushing step is essential; it flushes out any manufacturing residues and activates the filter media. Overall, it combines well with most 5 or 6 stage reverse osmosis systems to create an upgraded filtration stage focused on remineralization and alkalinity.

What Makes It Stand Out?
Compared to other remineralization filters on the market, the Geekpure inline alkaline filter stands out for its comprehensive kit that includes adaptable fittings and tubing, ensuring it can fit multiple types of RO systems with minimal hassle. Some competitor filters require separate purchases for connectors or only fit specific tubing sizes, which Geekpure packages neatly in one box.
While several brands focus only on boosting pH without adding significant minerals, Geekpure’s blend adds a balanced mix of calcium, magnesium, sodium, and potassium. This provides a more natural taste and supports health benefits beyond simple alkalization.
Another contender may offer an integrated remineralization filter, but usually at a larger size and higher complexity in installation. The Geekpure filter is designed for quick retrofit installation with minimal tools or plumbing changes.
This makes it a favorite for those who want both easy upgradeability and effective mineral supplementation without replacing their entire RO system.

Pros and Cons to Consider
Who Is It For?
This Geekpure alkaline filter kit fits a few distinct personas very well:
- Homeowners with existing reverse osmosis systems who want to restore natural minerals and improve water taste.
- Health-conscious individuals aiming for alkaline water with added calcium, magnesium, and potassium for daily hydration benefits.
- Anyone with a 5 or 6 stage RO filtration setup looking for an easy installation upgrade without swapping out major components.
If your RO water tastes overly acidic or flat, and you’ve been considering an enhancement for improved quality and hydration, this filter is designed just for you. Additionally, people who want convenient, modular upgrades to their water system infrastructure will appreciate the included fittings and tubing options.
Expert Advice to Maximize Results
To get the most out of your Geekpure alkaline water filter, flush the new filter for about 15 minutes before first use. This step clears manufacturing dust and primes the filter media. Keep a replacement schedule every 3 to 6 months depending on your water usage and quality; replacing it on time ensures you receive consistent minerals and alkalinity.
Make sure all fittings are snug to prevent leaks. If your RO system uses 3/8” tubing, use the included adapters instead of forcing a smaller connection. Proper installation protects the filter from premature damage and maintains water flow rates.
For those upgrading a 5 stage system, adding this filter creates a 6 or even 7 stage filtration process, enhancing both purification and mineral content. Regularly test your water pH if desired to monitor the performance and make adjustments accordingly.
