APEX RF-1050 Alkaline Filter Cartridge | Replacement for MR-1050 Countertop Water Filter

Overview

The APEX RF-1050 alkaline filter cartridge is a purpose-built replacement for the MR-1050 countertop water purifier. Made in the USA, this cartridge is designed to fit your existing purifier and maintain reliable filtration performance with straightforward maintenance for everyday hydration.

Filtration that Covers the Essentials

With a multi-stage approach, the RF-1050 targets a broad range of common tap-water concerns while preserving essential minerals. The result is water that feels fresher and more balanced for drinking and cooking, without complex installation steps.

• Five-stage filtration reduces sediments, hydrogen sulfide, chlorine, chloramines, and other chemicals that can affect taste and odor.
• KDF-55 media provides heavy metal reduction, helping address metals such as lead, iron, and mercury in the water supply.
• Activated coconut shell carbon adds natural minerals like calcium, magnesium, and potassium, contributing to a gentle shift toward mild alkalinity.
• Note: This cartridge does not lower total dissolved solids (TDS) or parts-per-million (PPM); for lower TDS, consider a reverse osmosis option.

What to Expect in Everyday Use

Expect water that tastes crisper with reduced aftertastes and odors, making it more enjoyable for daily drinking, coffee, tea, and cooking. The system is designed to support everyday hydration while helping you minimize reliance on bottled water.

• Improved water feel and flavor through mineral balance and filtration media.
• Clear, sediment-reduced water ideal for drinking and preparing meals.

Installation and Maintenance

Installation is designed to be simple and tool-free. Remove the faucet aerator, screw on the collar of the diverter valve, and secure the cartridge to the unit. If you need assistance, APEX EXPRT support is available to help you complete the setup and start filtered water quickly.

• Very easy twist-on installation; no plumber required.
• Replacement cadence is typically 4–6 months, depending on water quality and usage.

Warranty and Compliance

APEX backs the RF-1050 with a 30-day guarantee and a 1-year warranty against defects in materials and workmanship. All components comply with NSF/ANSI standards, reflecting a commitment to reliable, safe home filtration.
