SKU CH-JWHB-GN0MQ MPN U30012

Two replacement wick filters for Optimus U-33100 humidifier, pack of two

  • Replacement wick filter designed for Optimus U-33100 humidifier
  • Two filters per pack provide extended use between changes
  • High-quality media helps protect against bacteria growth
  • Genuine Optimus part ensures proper fit and function
  • New condition guarantees full filtration performance from first use

What this pack does

The Optimus U30012 pack contains two replacement wick filters made for the U-33100 humidifier. They trap mineral deposits and impurities so the unit can emit clean moisture. Homeowners who run their humidifier daily will find the twin pack convenient for regular change-outs.

How it handles daily running

The wick material resists bacterial growth while absorbing water evenly across its surface. Air passing through stays free of loose fibres, so the humidifier operates quietly without extra strain on the fan. Normal use sees the filter maintain its shape without shedding.

What happens over weeks of continuous use

Mineral build-up gradually reduces evaporation efficiency, so the filter should be swapped on schedule rather than run until it clogs. The two-pack layout lets you keep a spare ready, avoiding gaps in humidification during heavy seasonal demand.

Questions about this item

How do I install the U30012 filter in my U-33100 humidifier, and what step do people often miss?

Open the humidifier housing, remove the old wick filter, insert the new U30012 filter ensuring it sits flat in the frame, then close the housing securely. The step often missed is checking that the filter is fully seated with no gaps around the edges.

When will the U30012 wick filter need replacement?

Replace the filter when it becomes discoloured, hardened, or shows reduced water absorption, typically after one to three months of daily use depending on water hardness and runtime.

What is the first limit I will hit when running the U-33100 continuously with these filters?

The first limit is the filter's saturation rate; once the wick can no longer draw water fast enough to match the fan output, humidity output drops until the filter is replaced.
