Guest guest Posted January 10, 2011 Report Share Posted January 10, 2011 I think that is a bit high. Our humidity in the basement right now, in land, is 35%. What are 'normal' levels of humidity in a house? It is a rainy day here and humidity is at 70% inside which seems very unusually high.

Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 I keep my basement at 40% (windows closed at all times, 2 dehumidifiers going all the time and a humidex) and that seems to work for me. > > > I think that is a bit high.

Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 I wanted to know about normal humidity levels for a home too so I googles it. Said between 30%-50% is normal range. 70% is high and I run a dehumidifier because of that. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 Good grief, its pretty much 70% humidity in all the rooms in this house! ________________________ On 2011-01-12 06:28:46 +1100 surellabaer <surellabaer@...> wrote: > > I keep my basement at 40% (windows closed at all times, 2 dehumidifiers going > all the time and a humidex) and that seems to work for me. > > >> >> >> I think that is a bit high.

Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 what is the outside humidity level right now? can you find out? with my WDB the humidity inside was more this twice as high outside several times it was checked. it would be important to know if this is a pretty constant humidity level in your home or just related to high humidity days outside. I think so anyway. > > Good grief, its pretty much 70% humidity in all the rooms in this house! > > > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 Mites thrive over 50% relative humidity, and mold at 50-60% (I have seen some say 50, but I think 60 is most accurate).

Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 Jodie, Where do you live that you have 84% RH today? At what temperature? What type of humidity measuring device are you using? The less expensive mechanical types are grossly inaccurate but most digital ones are reasonably accurate.

Guest guest Posted January 11, 2011 Report Share Posted January 11, 2011 If it's high outside, no unusual to be that high indoors. Unless you are using A/C and doors closed. Then you should be near 50. The big problems with high RH (e.g., 70% and up) are 1. dew point temps on surfaces indoors, that is where moisture will condense/precipitate and the liquid becomes a problem to eithe the material or will contribute to mold/bacteria growth. 2. Absorption of vapor (water in air) into soft hygroscopic materials like paper, cloth, wood, etc. Then you get similar problems if it's long enough. Usually, however, the RH goes up and down, and the low periods are frequent enough to prevent problems. If it starts to smell bad, then your problem has begun. Also, ventilation, regardless of RH, over the surfaces will help to prevent mold growth on many surfaces. > > What are 'normal' levels of humidity in a house?
