I have had one for over a month now and can tell you it's a load of junk, put one behind the curtains to take care of the overnight moisture on the window and it can't even do that in such a small space (1 cubic meter at most).

Sure it collects water but nothing like it needs to make any difference, my electric one can collect in half an hour what this collects in 24hours.

Don't waste your money.

I bought one from ASDA last week for £10 and it started producing water in the tank. Looks like its working.

Got a few of these a long time ago from Asda for £10, they are great. Heat added.

Apparently they are good for dampness, mould, cooking odour/condensation, blistering paint, corrosion etc..!! Comments are welcome. I do not have any long term experience.

Note that the standalone comes with 1 cartridge, as the site is quite ambiguous in places.

Got 4 of them, all doing fine and seem to be working

​thanks. I did not have high expectation s when I bought it though.

Good deal. These are great. Although they are currently on offer in B&Q at 2 for £15 (if like me online shopping is a hassle because I'm never home when parcels get delivered - woe is me).

Anyone say it is great. Do you actually use hygrometer to monitor its effect.

There is something does not add up.

Suppose one tab works for one month, absorb a full tank of water, that is only around 1L.

Absorbtion rate of 1L per month per room. To me, that is really bad, should not have any really effect.


Anybody care to share why they are great?

I bought 15 last year to use.

I found their running cost is very high. You can only see the tank gradually fill up with blue water over one month. And think they must be doing a good job. At that kind absortion rate, it is not going to be useful. To me, it is a con.

I do not feel humidity any difference with or without them.


You would be much better off to buy an electronic dehumidifier to give you some really effects. You have to fact in the electricity consumption though.
