Type of Filter: It is a countertop water filtration system that works on reverse osmosis.

Design: AlcaPure RO has a compact, stylish, and modern design that suits every kitchen. You don’t need to attach any leaky diverter valves or huge houses to the sink faucet.

Weight and Size: The height of this countertop water filter is 16.25 inches. Its length is 14.5 inches, and 9.5-inch is its width. And if we consider its weight, then it is 23 pounds.

Installation: It doesn’t require any assembly or installation. It is a pre-installed unit that is ready to use.

Working: Its patented technology makes it quite easy to get pure water. It works just like a coffee maker. All you need is to fill the bottom pitcher with 1 gallon of tap water and press the push button. After 15 minutes or so, the top container will be filled with 0.5 gallons of pure and clean water, and the machine will then turn off automatically.

Filtration Stages: Four stages of advanced filtration make the water free from harmful contaminants.

Removal of Contaminants: The first filtration stage has a 5-micron PP Sediment filter that eliminates both the large and small particles in its outer and inner layers. It can remove rust, sand, and sediment.

The second stage is featured with Coconut Based Activated Carbon Block Filter that extracts VOCs (Volatile Organic Compounds), pesticides, Trihalomethanes (THM), bad taste, and odor.

The NSF/ANSI 58 certified RO membrane is the part of the third filtration stage with a filtration capacity of 75 GPD (Gallons per day). This RO membrane removes all the remaining harmful contaminants.

The last stage carries an AlcaPure Post Filter that reintroduces beneficial minerals like Calcium and Magnesium to enhance the water taste. It increases the water alkalinity level up to 8 pH.

RO Booster Pump: This zero installation dispenser also features a CE certified booster pump that is responsible for increasing the flow rate.

Recovery Rate: It has an excellent recovery rate of 50%. It means the system wastes 1 gallon of water to give 0.5 gallons of filtered water.

Filter Replacement: Filter replacement is also quite easy. You will be notified via blinking red light every 12 months for a recommended filter change. And the steady red light will notify you about the replacement of the RO membrane every 24 months.

Warranty: The system comes with a 1-year limited warranty.

My Opinion:

It doesn’t require any installation and is easy to maintain. The RO booster pump keeps the flow rate in check. And it has an excellent water recovery rate of 50%.

Cons: Its flow rate affects because of temperature. Also, sometimes it leaks.

Comparison between AlcaPure Edition and OnliPure Edition

AlcaPure RO countertop water filter makes the water alkaline. On the other side, OnliPure edition reduces all remaining contaminants left by the RO membrane. It doesn’t improve the water taste but helps it to achieve zero TDS (Total Dissolved Solids).

You can order any edition to meet your requirements. But it is better to go for the AlcaPure.

The plastic used is BPA-free. It means no Bisphenol A is used in the construction of the plastic. It is recommended to use BPA-free plastic, especially to contain the drinkable liquids.

According to research, BPA addition may cause heart diseases and other problems.

You can store 0.5 gallons of filtered water in about 15 to 20 minutes.

What is the best time to replace the RO filter?

It is recommended to replace it every 2 to 4 years. Without the proper function of the RO membrane, you cannot get fully purified water.
