Humidifier STANDARD Filter Core Wick Refill - Single

$0.99 NZD

The 750ml H2O Smart Humidifiers (in Snow and Blush), Milkbox Mini Humidifiers (in Vanilla Mint and Strawberry), and 200ml Mini H2O Humidifiers all use these standard cotton core wicks, just trim shorter to size.

This is for ONE standard size filter core wick refill, which will last on average 3 months (see below about how to extend this, what to avoid that shortens how long they last, and what to look for to know when to replace them).

Note the 1.1 litre H2O Smart Humidifier (the Sage green model), uses the large core wick refills. All models come with 1 or 2 wicks already included.

Each standard wick refill measures 15cm long x 8mm diameter. The H2O 750ml wick won't need trimming, the Milkbox and Mini wicks will need to be trimmed shorter , which is easy to do (always keep your old core to match the length when your new core arrives).


How long does a humidifer filter core wick last?


It varies depending on use, but a core tends to last 1 to 6 months, on average it's recommended you check and replace your core every 3 months (4 times a year). Running in a dusty or smoky environment will mean your core needs replacing more often. Harder water with higher mineral content can also shorten the core life.

To extend the life of each core, keep surrounding surfaces wiped clean of dust and floor area vacuumed / swept clean. You can also soak the filter in vinegar (just the filter, not the whole humidifier, always take the core out to soak it), once a month to dissolve water deposits.

If you notice any mould or discolouration from dust / minerals etc, it's definitely time to change the filter. Continuing to use a dirty or blocked filter can end up with dirt, dust or minerals making their way in to the filter itself and damaging your humidifier beyond repair.
