ULTRA SYSTEM REPLACEMENT FILTER THREE PACK WITH VIRUSGUARD - Cleaner

In this review of the ULTRA SYSTEM REPLACEMENT FILTER THREE PACK WITH VIRUSGUARD the reviewer finds it best suited for RV owners and anyone needing robust portable filtration; the single biggest reason to buy is the combination of a high-density 5 micron carbon block and a dedicated VirusGuard stage that improves taste and reduces microbial and chemical contaminants. Installation and use are straightforward, and the filters are intended as Original Equipment Replacement for the Clearsource Ultra Three Canister system, making them a direct, practical swap for existing owners.

Key Features

• Original Equipment Replacement: Designed to fit the Clearsource Ultra Three Canister system so users can replace cartridges without adapting housings or plumbing.
• VirusGuard protection: Adds a separate stage that targets bacteria, cysts, viruses and trace pharmaceuticals for safer drinking water in remote situations.
• 5 Micron Carbon Block: Uses high-density activated coconut shell carbon to reduce taste and odor while removing many petrochemical residues.
• Rust-Inhibiting Construction: The Clearsource rust-inhibiting cartridge design helps protect internal filter components and extend service life in variable water conditions.
• Multi-Layer Construction: Layered media balances particulate capture and adsorption so water runs clear while retaining flow performance suitable for on-board RV use.

Who It's For

This filter pack is ideal for people who already own the Clearsource Ultra Three Canister system and want a direct replacement that restores the original filtration stages, especially RV users and campers who need reliable water quality on the road. It also suits households or small groups that draw water from varied sources and want an extra layer of biological protection with the VirusGuard stage.

Those who should look elsewhere include users without a compatible three canister system or anyone seeking a simple single-stage pitcher or faucet filter; this product is built for a multi-canister configuration rather than a counter-top convenience solution.
