Clatterans

Clatterans is an online-only retailer specializing in replacement water filters for refrigerators, ice-makers, and household filtration systems. The catalog spans 40-plus refrigerator brands (Whirlpool, LG, Samsung, GE, etc.) and includes pitcher, under-sink, and whole-house cartridges. Prices sit in the budget-to-mid-range band: most refrigerator filters sell for $18–$35, roughly 30–50 % below OEM list prices, and multipack bundles drop the per-unit cost further. The company positions itself on certified aftermarket compatibility: every filter is advertised as meeting NSF/ANSI 42, 53, and 401 standards for chlorine, lead, and emerging contaminants while matching OEM fit and flow rate. Clatterans’ best-known lines are the “CL-RF” refrigerator series and the “MAXBLUE” universal pitcher cartridges, both promoted with independent lab data and lifetime “no-leak” guarantees. Frequent 4- and 6-pack bundles plus subscription discounts reinforce the value message. Core buyers are cost-conscious homeowners and renters who want OEM-grade water quality without paying retail mark-ups; they typically own mid- to high-end refrigerators that require filter changes every six months. The brand appeals to pragmatic, DIY-oriented consumers who value third-party certification, doorstep delivery, and bulk savings over brand-matching packaging. Clatterans competes in the crowded post-sale filter aftermarket, where low-price generics, private-label store brands, and discount OEM resellers all undercut one another. It differentiates through breadth of model coverage (1,200+ SKUs), published lab certificates, free U.S. shipping on any order, and a 90-day money-back guarantee—policies that shift risk away from the shopper and support repeat subscription revenue.
