We are often told about outdoor air pollution, heavy traffic, bush fires and the like that can be dangerous when acute and also long term. However you can get bad air indoors too and has the added problems that it is often circulated around and around and we keep breathing it in each time.
This article Too many smelly candles takes another look at the problem. This excerpt will give you the flavour:
According to the US Environmental Protection Agency (EPA), levels of indoor air pollutants are typically more than three times higher than outdoors.
Sources of indoor pollution can be many: cooking, heating, scented cleaning products, and also the products we use to deodorise our living or working spaces â whether theyâre candles, diffusers, room sprays, gels, beads or other products.
Indoor air pollution comes from a myriad of sources and can be in the form of droplets, gasses or solid particles. The author skips over some (like manufactured goods that out-gas) mentions others (cleaning products) but focuses on those we introduce deliberately to make the air smell âbetterâ. Ironically the last group can actually be bad for us in some cases, as the author points out. I was somewhat disappointed that the author did not join the dots between the types of pollution and where they come from and hence how to deal with each but the piece may have been edited unsympathetically.
The closing advice is:
Some other measures you may consider to make your indoor environment cleaner and healthier are frequently ventilating spaces, using vacuum cleaners with HEPA filters, using air purifiers, surrounding yourself with greenery, and cleaning regularly.
That pretty well covers it. The observant reader will have noticed that the best advice - to open the windows - contradicts the routine that we are given to save energy in our air-conditioned house, to have a well insulated house and to make sure the doors and windows seal well.
The way I handle that is to ventilate at the best time. In summer my house is open in the cooler hours (depending of weather) from midnight til dawn. This not only clears the air but cools the house for a good start in the morning. In winter it is open during the warmer hours in early afternoon where possible. The aircon goes off then of course.
A further confession, I hate strong perfume, air freshener that is worse than what it tries to cover, scented candles and those bubbly gurgling misty smelly gadgets that purport to improve the air. I have to leave if bleach is deployed. The result is, due to obligations of domestic compromise, the burning kind are banned but we do have the noncombustible type, but not very often.
Do you find juggling air freshness and other considerations such as energy efficiency and personal taste a problem?
