  • 5.1 in outer diameter · anti-clockwise thread
  • 15 in retracted to 80 in extended
  • Polypropylene with an internal steel ring
  • Check mounting size and thread orientation, not brand

The sentence this whole shelf needs

Do not focus on the brand of the portable air conditioner, focus on the mounting size and thread orientation!

Three listings here print lists of compatible brands. Those lists are reassuring and nearly useless: the same maker sells machines with different collars, and a hose fits a collar, not a logo.

This is the only listing that says so.

And the size nobody else has

Five point one inches. Between the 5-inch and the 5.9-inch hoses on this shelf, and compatible with neither.

If that is your collar, the shelf has one answer.

The questions that keep coming up

Is 5.1 inches really different from 5?

Yes. A tenth of an inch is enough to stop a threaded collar engaging, which is why this listing leads with a "Critical Alert" about it. Three diameters appear on this shelf — 5, 5.1 and 5.9 — and none of them substitutes for another.

What is the best way to check my machine?

This listing answers it better than any other on the shelf: *Do not focus on the brand of the portable air conditioner, focus on the mounting size and thread orientation.* Brand lists are marketing; the collar is physics.

Is the length fixed or adjustable?

Adjustable. The bullet is headed "Fixed 80-Inch Length" and then says it extends up to 80 inches and shortens to 15. The heading is wrong and the body is right.

    • The only product on this shelf that supplies the window plates as well as the hose, so one purchase finishes the job
    • Includes sealing tape and explains where it goes — at the gap between the fixing plate and the adjustable plate
    • No coupler, and the coupler is the part that actually threads onto the machine

    Best for: A sliding window that needs both a new hose and a proper seal, where the original coupler still exists

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

    A 150 mm (5.91 in) exhaust hose FanGoFast builds to a stated 6 m (20 ft) length, stretchable to about 6.5 m (21 ft), from aluminum foil, PVC, PET and a steel spiral core, rated -30°C (-22 °F) to 80°C (176 °F).

  • Levoit foam water tank sponge filter 10-pack for humidifiers

    Levoit Water Tank Sponge Filter (10-Pack)

    A 10-pack of small foam filters that sit inside the water tank on several Levoit humidifiers, including the Classic 160 and Classic 300S reviewed on this site, catching fine mineral and dust particles before they reach the ultrasonic mist plate. Confirmed with a live offer on Amazon.de; we found the same listing on Amazon.fr but did not verify a live offer there at the time of checking.

    What it is
    Foam sponge filter, sits inside the water tank
    Compatible models
    Levoit Classic 160, Dual 150, Dual 200S, Classic 300(S), LV600S, per Levoit

    0810043377256
    • Fits both reviewed Levoit humidifiers on this site — the Classic 160 and Classic 300S — from a single purchase
    • A 10-pack covers roughly two years of replacement if used per Levoit's suggested interval, working out to a low per-unit cost
    • This is a tank filter, not a replacement tank or reservoir — check you actually need this part before ordering, rather than a full tank replacement

    Best for: Owners of the Levoit Classic 160 or Classic 300S doing routine tank maintenance, distinct from anyone whose actual problem is a cracked or leaking tank body.

  • Metronic 495348 universal air conditioner remote control with LCD display

    Metronic 495348

    Metronic's 495348 is a universal air conditioner remote the brand states is compatible with up to 100 air conditioner brands, set up either by automatic search or by entering a code from the included brand list. It has a large display, a quick-cool and quick-heat function, a programmable on/off timer, and 5 operating modes.

    Compatible brands
    Up to 100 brands, per Metronic — names Carrier, Daikin, LG, Samsung, Johnson, Panasonic, Mitsubishi, Funai and Fujitsu among others
    Setup
    2 modes — automatic search, or manual code entry from the included brand-code booklet
    Operating modes
    5 — auto, cold, warm, dehumidify, fan
    Extra functions
    QuickCool and QuickHeat; TIMER ON / TIMER OFF programming
    Display
    Large LCD
    Power
    2 × AAA (AM4/LR03) batteries, not included
    Dimensions
    16.5 × 5.5 × 2 cm (6.5 × 2.2 × 0.8 in), per Metronic
    Amazon reference
    B098BNRJY9 (EAN 3420744953481) — live offer confirmed on DE/FR/IT/ES; the same EAN matches a listing on Amazon UK with no current live offer at the time we checked; no ASIN found on Amazon US
    • A printed code list Metronic states covers roughly 100 brands, plus an automatic-search setup mode, against the shorter set of named brands the Hama remote in this hub ships pre-programmed for
    • 5 operating modes (auto, cold, warm, dehumidify, fan) plus a programmable on/off timer and dedicated quick-cool/quick-heat buttons
    • None of the roughly 100 brands Metronic names in its own listing match the portable air conditioners reviewed on this site (Dreo, Gymax, Okyuk, Temprium); a universal remote's success still depends on the exact model being on the code list, which we can't confirm without the printed sheet in hand

    Best for: An air conditioner from one of the roughly 100 brands on Metronic's own code list — a wider net than the Hama remote in this hub, which is pre-programmed for a shorter set of named brands only.

  • MSemis plastic replacement fan blade set, 400mm

    MSemis Replacement Fan Blade Set 400mm

    A generic-fit replacement blade set (3 or 5 blades, plastic, 400mm (15.7 in)) for classic desk and pedestal fans with an exposed rotor. None of the pedestal or tower fans reviewed on this site use this design — they're bladeless or fold-flat units — so this accessory serves classic-design fans a household might own outside this site's own picks. Confirmed with a single live offer on Amazon.de; we did not find a listing on the other three markets we checked.

    Blade diameter
    400mm (15.7 in)
    Blade count
    3 or 5, per the listing variant
    Fit type
    Generic — classic exposed-blade fans only
    Material
    Plastic, includes a nut cover
    • Confirmed with a live offer on Amazon.de
    • A cheap fix for a wobbling or cracked-blade classic fan, rather than replacing the whole unit
    • Does not fit any of the pedestal or tower fans reviewed on this site — they're bladeless or fold-flat designs without an exposed rotor

    Best for: Anyone repairing a separate, classic exposed-blade desk or pedestal fan — not a fit for the specific models reviewed on this site.
