Confirmed but confidential: the compatible-model list doesn't include the reviewed unit

Dreo Demineralization Cartridge (3-Pack)

Dreo's own demineralization cartridge, sold as a 3-pack, stated to fit its HM311, HM306 and HM524S humidifiers. Dreo's own listing does not name the DR-HHM006 reviewed on this site as compatible, so we're not claiming a fit — this entry reports the part honestly as an official Dreo accessory for a different segment of the brand's range. Confirmed with a live offer and 2 sellers on Amazon.de.

A real part, for a different Dreo range

Dreo’s own listing for this demineralization cartridge names the HM311, HM311S, HM306 and HM524S humidifiers as compatible. The DR-HHM006 reviewed on this site isn’t on that list — a different series within the same brand’s lineup. We’re including this accessory because it’s a genuine, confirmed product from a brand already covered in this network, not because it’s confirmed to fit the specific unit reviewed here.

Why hard water matters for this part

A demineralization cartridge is only relevant for households on hard tap water — it absorbs the dissolved minerals that would otherwise settle as white dust on surfaces near an ultrasonic humidifier. Softer water may not need scheduled cartridge replacement at all; check your local water hardness before assuming this is a necessary purchase.

  • Elektrobock TS05 digital plug-in outlet thermostat with LCD display

    Elektrobock TS05

    Elektrobock's TS05 is a digital plug-in thermostat with a relay output stated as max. 16 A, switching a connected heater between +3 °C and +40 °C in 0.5 °C steps, with a frost-protection floor at 3 °C and settings that Elektrobock states survive a power cut.

    Max. load
    230 V / 50 Hz, relay output stated as max. 16 A — Elektrobock does not publish a watt figure directly; at 230 V that computes to about 3 680 W
    Temperature range
    +3 °C to +40 °C, adjustable in 0.5 °C steps
    Hysteresis
    0.5 °C, with a stated measurement accuracy of ±0.5 °C
    Frost protection
    Built-in, engaging at +3 °C
    Power-cut behaviour
    Retains its settings through a power outage and resumes automatically, per Elektrobock
    Protection rating
    IP20; stated operating range 0 °C to +40 °C ambient
    Display
    Digital, with + / − and ON / OFF buttons

    B00YURX7BI (EAN 8594012221703, plus three further regional EANs on the German listing) — sold and shipped by Amazon on DE at the time we checked. A catalog page exists on FR/IT/ES/GB under a different ASIN (B01BVKTFXU) but carried no live offer or price on any of the four at check time; no listing found at all on Amazon US
    • Widest and coldest-reaching range of the three outlet thermostats in this hub: +3 °C to +40 °C, against +5 °C to +30 °C on the ChiliTec ST35 and the McPower TCU-330
    • A stated frost-protection floor at +3 °C, which neither of the analog units in this hub publishes
    • States its output as "max. 16 A" rather than a watt figure — the 3 680 W equivalent is our own arithmetic at 230 V, not a number Elektrobock itself publishes

    Best for: A cold garage, shed, or outbuilding where frost protection and a wide temperature range matter as much as the day-to-day thermostat function, and where settings surviving a power cut is worth having.

  • FanGoFast black 150 mm flexible exhaust hose extended to its full length

    FanGoFast FG-AIRDUCT6IN-6M

FanGoFast markets it for mobile air conditioners, washer-dryers, extractor fans and kitchen hoods generally, rather than for one declared appliance model — the longest reach of the three hoses in this hub.

    Inner 150 mm, per FanGoFast
    Length
    6 m stated, stretchable to about 6.5 m; can be cut shorter

    • Longest reach of the three hoses in this hub: 6 m stated, stretchable to about 6.5 m
    • No declared compatibility with any specific appliance model — it is sold by diameter (150 mm), not by machine

    Best for: A universal 150 mm hose for a longer run — an appliance placed well back from the window — for a buyer who has already measured their unit's own exhaust port.

    B0DQ1NGJ99 (EAN 4047443532305, identical on all six markets checked)
    • Confirmed with a live price on all six markets we checked — DE, FR, IT, ES, US and GB — the widest confirmed availability of the three remotes in this hub
    • Ships pre-programmed for the brands Hama names, with no code to look up and enter, unlike the Metronic remote reviewed alongside it
    • None of the brands Hama names — Daikin, Mitsubishi, Panasonic, LG, Samsung and others it doesn't list individually — match the portable air conditioners reviewed on this site (Dreo, Gymax, Okyuk, Temprium)

    Best for: A Daikin, Mitsubishi, Panasonic, LG or Samsung split or portable unit whose own remote is lost or broken — check Hama's brand list against your exact model before buying if your unit is a different brand.
