Frequently Asked Questions
How does the Tier1 CT-S-1000 Countertop Water Filtration System install on my faucet?
The Tier1 CT-S-1000 is a countertop system that connects directly to most standard kitchen faucets using the included diverter valve—no plumbing modifications or tools required. Simply unscrew your faucet aerator, attach the diverter, and connect the CT-S-1000’s tubing. The diverter allows you to switch between filtered and unfiltered water with ease. Note that this system is not compatible with pull-out or sprayer-style faucets.
What contaminants does the Tier1 CT-S-1000 reduce, and what is its micron rating?
The Tier1 CT-S-1000 Countertop Water Filtration System uses a high-performance 0.5-micron carbon block filter to reduce a wide range of contaminants, including chlorine taste and odor, sediment, rust, cysts, VOCs, and other common impurities found in municipal tap water. Its sub-micron filtration delivers clean, great-tasting water right at your countertop without sacrificing flow rate.
How long does the Tier1 CT-S-1000 filter last before replacement?
The replacement filter cartridge inside the Tier1 CT-S-1000 is rated for approximately 1,000 gallons of filtered water, or roughly 6 to 12 months of typical household use—whichever comes first. Replacement frequency depends on your local water quality and daily usage. If you notice reduced flow or a change in taste, it’s time to install a fresh cartridge to maintain optimal filtration performance.
Is the Tier1 CT-S-1000 NSF/ANSI certified?
The Tier1 CT-S-1000 is designed and tested to meet NSF/ANSI Standard 42 criteria for aesthetic contaminant reduction, including chlorine, taste, and odor. The carbon block media used in the system is manufactured to industry standards for reliable contaminant reduction. For full certification details and tested contaminant lists, refer to the product specification sheet on the Discount Filter Store product page.
What replacement cartridge fits the Tier1 CT-S-1000, and how do I change it?
The Tier1 CT-S-1000 uses a dedicated Tier1 replacement cartridge specifically engineered for this countertop housing. To replace it, shut off water flow at the diverter, unscrew the filter housing sump, remove the used cartridge, insert the new one, and hand-tighten the housing back in place. Flush the new cartridge for 5 minutes before drinking to remove carbon fines and activate the media for full filtration efficiency.
