FAQs
What impurities do your compact under-sink filters remove from Bluff City tap water?
Our systems use a multi-stage process (5-micron sediment pre-filter, catalytic carbon block, and a high-performance nanofiber membrane) that targets the most common contaminants found in Bluff Cityâs municipal supply. Independent lab tests show up to 99 % reduction of chlorine, chloramines, lead, mercury, VOCs, PFAS, cysts (Giardia & Cryptosporidium), microplastics, and unpleasant tastes or odors while retaining healthy minerals such as calcium and magnesium.
Will the filter housing actually fit in my cabinet space?
Yes. The under-sink model is only 11 in tall Ă 4.5 in wide Ă 12 in deepâabout the size of a small coffee maker. It mounts to the back or side wall of the cabinet, leaving room for cleaning supplies or a garbage disposal. If you have at least 12 in of vertical clearance, the unit will fit; our technician measures before installation to confirm.
How often do I have to change the filter cartridges and how much do they cost?
For the average Bluff City household (about 2â4 people with normal cooking and drinking usage), the sediment/carbon combo cartridge lasts 12 months or 1,000 gallons, whichever comes first. Replacement takes less than two minutesâjust twist off the housing, pop in the new cartridge, and hand-tighten. A genuine replacement pack is $48 and is available locally or shipped free in Bluff City with a subscription.
Can I install the system myself, or do I need a licensed plumber?
The kit includes color-coded tubing, push-fit connectors, and a dedicated chrome faucet, so a confident DIYer can complete installation in about 45 minutes with only an adjustable wrench and a drill. However, Bluff City building code requires that any modification to the cold-water line inside city limits be inspected, so most homeowners schedule our flat-rate professional installation ($129) to ensure compliance and warranty coverage.
Will the filter slow down my kitchen faucetâs water pressure?
Not noticeably. The system delivers a steady 1.6 gallons per minute at the dedicated filtered-water faucetâenough to fill a 16-oz glass in about 6 seconds. Because it operates on line pressure (no tank), your main faucetâs pressure remains unchanged. If your homeâs static pressure is below 40 psi, we can supply a booster adapter at no extra charge.
Are your products NSF certified and do you offer water testing for Bluff City residents?
Absolutely. The entire under-sink series is NSF/ANSI 42 & 53 certified for aesthetic and health contaminant reduction, and the membrane also meets NSF P473 for PFAS. After installation, we provide a complimentary on-site water test that checks chlorine, TDS, hardness, and lead. Youâll receive a printed report and guidance on any additional treatment steps if needed.
