Why customers choose TaskHolt Tools

Pure, great‑tasting water starts with the right cartridge. The APEX RF-1050 replacement cartridge is designed for the MR-1050 countertop water purifier and is made in the USA. This modern filtration solution addresses the realities of everyday tap water, where unseen impurities can exist even when the water looks clear.

Five-stage filtration you can rely on

Inside the cartridge, a layered system combines KDF-55 media with a coconut-shell carbon block to target a broad range of common contaminants. The result is water that feels crisper and reads clearer on the palate, ready for drinking, cooking, or making ice.

Key benefits at a glance

  • Easy installation — twist-on replacement that requires no plumber.
  • Better tasting water — reduces chlorine, chloramine, sediments, and other chemicals to enhance flavor.
  • Improved water quality — heavy metal reduction with KDF-55 and mineral-balanced carbon adds healthy minerals and helps raise alkalinity.
  • Cost and waste savings — eliminates frequent bottle purchases and reduces plastic waste; each cartridge lasts 4–6 months.
  • Support and warranty — 30-day guarantee; 1-year warranty; NSF/ANSI compliant components.

What to expect and quick notes

  • Note: This cartridge does not lower TDS or PPM readings. For TDS reduction, consider a different filtration approach.
  • Compatibility: designed for the MR-1050 countertop filter and attaches to most standard faucets.
