Quick Connect Water Filters
Drop-In Replacement for Everpure & 3M

What Is a Quick Connect Water Filter?
A quick connect water filter is an inline filtration cartridge that connects to your water line using push-fit fittings — no tools, no soldering, no plumbing expertise. Push the tubing into the fitting and it locks via a stainless steel collet ring with an EPDM O-ring seal. Press the collet ring to release. The entire cartridge change takes under 30 seconds.
Quick connect filters are the standard for commercial foodservice equipment (ice machines, coffee systems, beverage dispensers), residential under-sink systems, and refrigerator water lines. They are used in millions of installations worldwide and are manufactured in three standard push-fit sizes:

Frequently Asked Questions
- Are quick connect water filters compatible with Everpure head units?
- Yes. XZH U-type quick connect cartridges are dimensionally compatible with Everpure H-300 and 4FC head units (QL2/QL3 bayonet interface). I-type cartridges fit H-104 and 4SI series heads. The bayonet interfaces are manufactured to the same tolerances as OEM originals. Over 15 years of production history with zero compatibility complaints.
- Can I replace 3M/Cuno water filters with quick connect compatible cartridges?
- Yes, for 3M/Cuno systems using standard housings (CFS series, AP Easy, Aqua-Pure residential). These accept correctly sized open-platform cartridges at 30-50% lower cost. The only exception is 3M's proprietary SQC (Sanitary Quick Change) valve-in-head systems (HF, ICE, BEV series) which require 3M-only cartridges. See our 3M/Cuno cross-reference guide for model-by-model compatibility.
- What is the minimum order for OEM quick connect water filters?
- Standard configurations (existing media, white housing, your logo): MOQ 500 pieces. Custom media blends or custom housing colors: MOQ 2,000 pieces. Sample orders of 10-50 pieces are available for product evaluation. Lead time is 7-15 working days for standard orders. All pricing is FOB Ningbo.
- What filter media options are available for quick connect cartridges?
- XZH offers 7 standard media types for quick connect cartridges: PP (polypropylene) melt-blown sediment, GAC (granular activated carbon), CTO (carbon block), T33 (post-carbon), UF (ultrafiltration hollow-fiber membrane at 0.01 µm), KDF (heavy metal reduction), and RO (reverse osmosis membrane at 50/75/100 GPD). Custom blends combining multiple media types are available at 2,000 pc MOQ.
- How do quick connect water filters compare in cost to Everpure and 3M originals?
- OEM Everpure cartridges retail between $60-$180 per unit. 3M/Cuno originals run $40-$150. XZH compatible quick connect water filters are priced at $3-$12 FOB Ningbo (wholesale, depending on media and quantity). For a restaurant chain replacing 100 cartridges every 6 months, switching to XZH compatibles saves $5,000-$15,000 per replacement cycle.
