High Output Replacement Discs – 20mm Nonstick Ceramic Mist Maker Discs

The Easiest Fix for Weak Mist Output

💨 Always Free Shipping · Ships Within 1 Business Day

Worn discs are the most common reason for reduced mist output — and the easiest fix. These are the same high-output 20mm nonstick ceramic discs that ship with every House of Hydro mist maker. The clear nonstick glaze means longer life and easier cleaning, and at 20mm they are larger than the 16mm discs some competitors use — House of Hydro foggers run exclusively on 20mm.

✅ When to Replace Your Discs

• Mist output has dropped noticeably even after cleaning

• You cleaned the discs with vinegar and output is still weak

• Discs are chipped, cracked, or have heavy mineral buildup that will not come off

• You dropped a disc — hairline cracks can damage your transducer, so discard and replace immediately

🔧 Disc Replacement Tips

• Dry the transducer completely before removing discs — moisture in the spring area causes failure

• Use the silver disc key to unscrew the retaining ring; do not overtighten on reinstall

• The black ring on new discs is a shipping protector, not an O-ring — discard it and keep the clear O-ring in place

• Never touch the discs while the unit is operating
