Great dehumidifier but cannot get consumables
Pleased with the dehumidifier, does the job nicely, however I have not been able to find replacement filters the right size. The filters in Argos (Feb 2026) do not fit this machine, I tried to ask Argos using the Q&A but it got rejected 3 times. I have also searched elsewhere on well known sites and in general and cannot find them this size. So it could be difficult finding replacement filters for it. Might not have bought this model had I known. I think Argos has a duty to ensure consumables are available during the sale period of a product at least.

Good design, but not that efficient
I am pleased with the appearance of this item & also the fact that it is easily moved around as it is not heavy. Also, it is quiet, so it does not disturb you during the night - as it is in the bedroom. However, it is not that efficient. Does collect some water, but windows are still steamed up.

Very useful device
It is a helpful device and working well. It has capacity for leaving it running multiple days so the water tank won't overflow.. It can switch off automatically when a set humidity level has been reached, which is great. The light is unnecessary but can be switched off.

Fits neatly in the corner of room.
This is an ideal size to fit in the corner of our lounge in our cottage. We suffer with condensation and a small amount of damp, so in the winter a bit of mould growth around the base and corner of a cement plinth. Trying this compact dehumidifier to see if this will help that. It's not on constantly, so we'll see how it goes. It has several useful features so would probably be ideal in a bedroom too, if needed.

Unit fine. Filters unavailable at this time
The unit itself is fine, but I'm unable to get filters. Bush are not responding to requests from Argos help line. The filter needs to be changed every 3 months. I'm hoping that the filters will be available soon.

Great Piece of Kit!
I bought this item a few weeks ago for my son. They love in an apartment and we're plagued with condensation before. The dehumidifier collects half a litre of condensation every night!!

Very pleased
I purchased the dehumidifier so that my washing would dry faster and it does.
Do not have one, 65 or over
Think it works lol
Dunno if I'm using it right. A novice confused by the instructions so I put it on what I think but it's gathering water so I suppose I am :-)
