Hiya..hope you are all feeling ok now the weather is getting a lot cooler 😢

My question is will the dehumidifier I've just bought help my COPD??

AND sorry this isn't a health question but I can't find the answer anywhere. Does the "inside drying" button on the unit mean it's for drying clothes (on a clothes horse) OR it's for drying the actual unit inside ?? Sorry for being daft but hubby and I jst don't know lol. Take care everyone 😚😚

The recommended humidity level for a house normally ranges from 35 to 45 percent. At this humidity level, it is neither too dry nor too moist, which allows the residents to live comfortably. It also provides the best condition to keep the rooms and furniture from damage.

To high will create damp and possible mould. Not good for COPD.

To low and you may get cold like symptoms, not good for COPD.

A dehumidifier will extract all the moisture out of the air, may be to much. A humidifier will put moisture into the air.

You really need a test meter to see if and what the problem is.

Available from Amazon fairly cheaply.


I think the button on the unit is to switch on if you are drying clothes like you say. Presumably it increases the power of the unit to compensate for the damp you are putting out.

Hi. As Kernow says its for drying clothes inside. When you think about it there's a whole lot of water left in clothes after a wash cycle - when I buy a new washer I always ensure it has a spin cycle of at least 14.

I recall your post telling us about your very, very damp home. I bet your dehumidifier is collecting lots of water. Worth keeping a record for your claim back. After your post I ordered the one I'd kept forgetting to. It's great, only one little damp patch inside the basement fireplace. £72 well spent. I know yours was very much more expensive so it must be brilliant. P

No need to apologise, it WAS a health question 😃

Thanks for your reply. I ended up ringing the manufacturer regarding the "inside drying" button on the unit and it's actually for drying the inside of the unit itself to stop mould growing inside it. So I think I'll carry on using my tumble dryer lol

We have 2 de-humidifiers. Our cottage is solid masonry walls, with Upvc wiindows..........This combinations leads to condensation.

Cooking, boiling the kettle, using the shower,washing on airer to dry, even breathing, all put moisture in the air which has nowhere to go except settle on cooler surfaces such as inside windows and insides of outer walls............The larger humidifier copes with downstairs and a smaller portable deals with upstairs.

They really make a difference in the amount of condensation that forms.............

and condensation leads to the black mould that forms and the spores of that are very harmful to the respiratory system.

Thankyou ruach our cottage is exactly the same (walls & windows) so I'm hoping the dehumidifier does the job 🤔
