Consider Condensation
There is nothing more relaxing after a long day at work that a hot bath or shower, and while you might love either, dust mites, mold and viruses love them just as much, if not more! And it’s not just your bathroom, your kitchen can be a haven for these little critters as when you are boiling those potatoes to make some lovely creamy mash, all that steam soon turns into condensation.
So, if you are having a bath or shower, make sure you keep the door closed as much as possible, cover your pans when cooking and if you have an extractor fan in your home make sure it’s turned on. Failing that, just open a window so you keep the humidity levels in those rooms to a minimum.
