The SimPure Alkaline UV Reverse Osmosis System offers impressive purification capabilities, removing over 99.99% of contaminants such as viruses, bacteria, and heavy metals. Its pH range is boosted through an alkaline remineralization filter, adding essential minerals like calcium, magnesium, and potassium, which can be beneficial for health. Additionally, the built-in UV sterilizer ensures the elimination of microorganisms, making the water even safer to drink.

This machine is tankless, which saves space under the sink and prevents secondary contamination, and its maximum flow rate of 0.27 gallons per minute is quite efficient for household use. With a filtration system that produces up to 400 gallons of pure water per day and a 1.5:1 pure-to-drain ratio, it reduces water wastage significantly compared to traditional systems. The system is also designed for ease of use with quick-change twist filter cartridges, making maintenance straightforward.

One drawback is that the TDS (Total Dissolved Solids) level will not reach 0 ppm, which might be a consideration for users who prefer low TDS levels in their water. The product comes with a robust customer support system based in the USA, providing assistance when needed. The built-in pump is another advantage, ensuring consistent water pressure. This product would be ideal for households looking for a reliable and efficient water filtration system that also enhances the alkalinity and mineral content of their drinking water.

The Waterdrop Alkaline Lucid 10-Cup Water Filter Pitcher is a handy option for anyone wanting to enjoy healthier, alkaline water at home. Its pH range is quite impressive, increasing water pH up to 9.5, which can help slow aging and regulate body pH. The 6-stage filtration system effectively reduces fluoride, chlorine, and heavy metals, while adding beneficial minerals like zinc and calcium. This makes the water not only healthier but also improves the taste, especially noticeable in coffee by reducing acidity and enhancing natural sweetness.

However, it's important to note that it does not reduce TDS (Total Dissolved Solids), which are inorganic salts and small amounts of organic matter. So, if you prefer lower TDS levels, this might not be the best option for you. The pitcher is user-friendly with its ergonomic handle and gravity induct indicator, which signals when it's time for a filter change. Made from high-grade, BPA-free plastic, it ensures safe usage.

The dimensions should fit most refrigerators, but it's wise to measure your fridge to ensure compatibility.
