Homes that want a simple serviceable whole-house Big Blue setup for sediment plus chlorine/taste/odor treatment, with a reusable 30-micron sediment stage and a high-capacity GAC stage.
SYSTEM ARCHITECTURE
Water enters at the main line, moves through each treatment stage, and then feeds the entire house. The exact hardware varies by model, but the comparison logic stays the same.
SYSTEM TYPE
2-stage cartridge filter
Sediment or spin-down filtration protects downstream media when required.
Carbon, specialty media, ion exchange, oxidation or another primary treatment stage.
Softening, salt-free conditioning, UV or polishing filters may be separate components.

Published replacement life
Inspect the housings and monitor pressure drop and water quality. The first-stage FI-SED20-BB pleated sediment cartridge is washable/reusable. Replace the FI-CAB20-BB granular activated-carbon cartridge when capacity is reached or chlorine/taste/odor performance declines. APEC's current complete replacement bundle is FILTER-SET-CB2-20BB.
Normal major service is cartridge replacement rather than housing replacement. APEC sells FILTER-SET-CB2-20BB as the matched two-cartridge replacement set. The carbon cartridge's published capacity is more than 70,000 gallons at 4 GPM; the sediment stage should be cleaned/replaced based on loading and pressure drop.
APEC's current warranty page lists all 10-inch and 20-inch Big Blue/Clear/White/Black filters plus Big Duo, Big Trio and bundled systems under a one-year limited warranty against defects in materials and workmanship under normal use and service. Warranty exclusions and shipping/claim conditions apply.
APEC makes broad chlorine, chemical and VOC adsorption claims for this system, but FilterTier did not verify a current third-party contaminant-reduction certification for this exact CB2-SED-CAB20-BB model. The published 15 GPM figure is a system pressure-drop test point (1 psi at 15 GPM), while the carbon cartridge capacity is specified at 4 GPM; do not confuse those two figures. This is not a water softener and should not be treated as hardness, PFAS or microbial treatment without separate evidence.
ORIGIN & MANUFACTURING
FilterTier distinguishes headquarters, design, manufacturing and final assembly. When an exact model's origin is not publicly confirmed, we say that instead of guessing.

WHY IT MATTERS
Country-of-origin can affect buyer preference, serviceability, parts availability and perceived manufacturing quality — but it is scored separately from filtration performance.
FILTERTIER PRICE TRACKER
We track observed selling prices over time and compare today's price with the system's normal range. Crossed-out MSRP and perpetual “50% off” labels do not count as meaningful savings.

LAST CHECKED
October 2, 2026
Manufacturer-direct APEC price observed at $279.99 on 2026-10-02. FilterTier does not infer a discount from a missing/unclear regular price.
If a system is almost always sold at 40–55% off MSRP, FilterTier treats that sale price as the normal market price and judges value from there.
INSTALLATION CONTEXT
• Main-line size and connection diameter • Available service flow and incoming pressure • Drain requirement / backwash routing • Electrical outlet or UV/controller power • Tank/cartridge replacement clearance • Bypass and isolation valves • Pressure gauges before/after restrictive stages • Floor drain / leak protection where appropriate
The best treatment spec is still the wrong purchase if it cannot be installed, serviced, or supplied with enough flow in your actual house.
