Verified Compatibility Before You Order

Verified Compatibility Before You Order

When a generic supplier ships the wrong filter cartridge for your Haws 1200 series cooler, your water goes offline and your facilities team scrambles. Water Station's Pre-Purchase Spec Review confirms model compatibility and your expected gallon usage before your PO goes through — so you receive the right NSF-certified cartridges the first time. No guesswork, no returned shipments, no downtime for your public hydration infrastructure.

Certified Protection Against Contaminants

Certified Protection Against Contaminants

Each carbon block cartridge is tested and certified by CSA against three NSF/ANSI standards: Standard 42 for chlorine taste and odor reduction, Standard 53 for lead reduction, and Standard 401 for microplastics reduction. This multi-standard certification ensures the water your visitors, students, and staff consume meets institutional safety requirements — not just basic filtration. The on-board chip interfaces with the Electronic Lifecycle Control system to shut off water flow once the 3,000-gallon capacity is reached, preventing service past the certified lifespan.

One Year of Uninterrupted Supply

One Year of Uninterrupted Supply

This twelve-pack keeps your Haws 1200 series water coolers operational for a full year at rated capacity. At 3,000 gallons per cartridge, a single pack delivers 36,000 gallons of filtered water — enough to support high-traffic facilities without emergency reorders mid-season. For parks departments and school districts managing multiple units, bulk ordering through Water Station means consistent filter inventory, predictable replacement schedules, and net-30 terms for government entities. Free shipping included on every order.

“Last year we switched to Haws 1200 series coolers and needed a reliable filter source. Water Station confirmed the 6428-C compatibility before we submitted our PO — our procurement office had the spec sheet same day. The Electronic Lifecycle Control system eliminates any guesswork on replacement timing. Twelve filters, one year, no issues.”

Frequently Asked Questions

No. Model 6428-C filter cartridges are spec'd specifically for the Haws 1200 series water coolers. Using the wrong filter model can compromise the Electronic Lifecycle Control system and void certification. Contact Water Station before ordering and we'll verify compatibility with your exact cooler model through our Pre-Purchase Spec Review — at no cost.
These carbon block cartridges are CSA-tested and certified against three NSF/ANSI standards: Standard 42 for chlorine taste and odor reduction, Standard 53 for lead reduction, and Standard 401 for microplastics reduction. This triple-standard certification goes beyond basic particle filtration. Certification documentation is available for your facilities compliance officer upon request.
Each 6428-C cartridge contains an on-board chip that tracks total gallon usage in real time. The chip interfaces with the Haws 1200 series Electronic Lifecycle Control system, which allows water to flow only until the filter reaches its 3,000-gallon capacity. Once the limit is reached, the system shuts off flow — so expired filters are never used past their certified service life.
Lead time varies by inventory status. Water Station states current lead times on every product page before you order — no 'contact us for availability' delays. If your park or facility has a specific installation deadline, contact us and we'll confirm the ship date against your project schedule before your PO goes through.
Yes. Water Station accepts institutional purchase orders with net-30 terms for government entities, school districts, parks departments, and municipal buyers. Contact us before checkout to set up your account and we'll provide the documentation your procurement office requires — including spec sheets and certification details. We work with standard government purchasing processes, not against them.
Water Station handles freight damage claims directly — you do not deal with the carrier alone. Inspect your twelve-pack shipment upon arrival and report any damage to us immediately. We coordinate the claim process and arrange replacement cartridges shipped to your facility, so your maintenance schedule stays on track and your team isn't left managing carrier disputes.
