The Tier1 844-RM is a replacement carbon media bag designed specifically for Tier1 whole house carbon filter systems. It contains premium coconut shell-based granular activated carbon (GAC) that reduces chlorine, chloramines, bad taste, odors, and VOCs (volatile organic compounds) throughout your entire home's water supply. This bulk replacement media refills your existing Tier1 whole house carbon tank, restoring it to full filtration performance without the need to replace the entire system.

The Tier1 844-RM carbon media typically lasts 3 to 5 years, depending on your household's water usage, incoming water quality, and chlorine levels. For an average family of four on municipal water, expect approximately 1,000,000 gallons of filtration capacity before replacement is needed. If you notice a return of chlorine taste or odor in your water, it's time to replace the media with a fresh 844-RM refill.

The Tier1 844-RM replacement media is specifically engineered to fit Tier1 whole house carbon filter systems that use a standard carbon tank configuration. It is designed as a direct refill for Tier1 backwashing and non-backwashing carbon tank systems. Always verify your tank size and media volume requirements before ordering to ensure you purchase the correct quantity for a complete media bed replacement.

Yes, if your Tier1 whole house system is equipped with a backwashing control valve, the 844-RM carbon media benefits from periodic automatic backwashing (typically every 3–7 days) to prevent channeling and remove trapped sediment. This extends the life of the carbon bed. For non-backwashing Tier1 systems, no routine maintenance is required between media changes, though installing a pre-sediment filter upstream is recommended to maximize the lifespan of the 844-RM media.

The Tier1 844-RM uses high-grade coconut shell activated carbon manufactured to meet NSF/ANSI Standard 61 material safety requirements, ensuring the media is safe for potable water contact. The coconut shell GAC provides superior micro-porous structure for effective chlorine and organic contaminant adsorption throughout your whole house. For best results, flush the system thoroughly after installation to remove any fine carbon dust before using the water for drinking.
