Good question -- but all filters are not created equal. Some are disposable and others are cleanable. Pleated disposable filters last longer (maybe 3 months) than the cheapest of the fibreglass filters (one month). In fact the 3M Filtrete filter, the top of the 3M series of filters, is rated a...
(This entry was originally submitted as an article to Chatelaine Magazine. The heavily edited version which appeared in September 2008 was a fine little article, but missed some critical points like exhausting central vacs outdoors, not making the critical distinction between the bad ozone air c...
Mould will form anywhere you have moisture for a long period of time at a warm temperature. Some moulds grow and feed on organic materials including drywall paper, wall paper glue and of course wood. Other moulds simply grow on the surface, which means that moulds can grow wherever they can...
Exhaust fans are the minimum necessary in houses for taking out stale air. You may have a fan, but it may not be working. It could be clogged up, improperly installed or simply too noisy for anyone to turn it on. Quiet fans, with good controls are a must in our energy efficient and often stuff...
Stale, humid air must be exhausted from the house, both to allow for fresh air and to maintain a high neutral plane. For this reason we need a planned-hole-high-in-the-house, but the air going out must come into the house from somewhere. If you carefully seal all the leaks in the house to m...
Yes -- if the cold-air input is uncontrolled. In fact, uncontrolled cold-air drafts are the reason for dryness in older houses. Damper control of the cold-air intake (not the hot-air exhaust) will allow you to maintain whatever level of humidity you want.If your furnace combustion air is provid...
A balanced air-change system is a fan operated system that forces out stale air through exhaust ducts and forces in an equal amount of fresh air through controlled intake ducts. The difference between this and a central exhaust system is that the input air is under active control and balance...
Grandpa had winter air quality problems in his house -- it was always too dry and an occasional back draft would fill the room with smoke. Other than that, pollution or the absence of air didn't pose a problem. Why? His drafty old house worked like a fresh running stream -- it continually ...
In a house of any size it is easy to get sufficient oxygen for breathing. If a combustion furnace is not operating you could live for days on the oxygen in your house with no fresh air at all. What we often mistake for a lack of oxygen is a concentration of pollutants. Carbon dioxide (CO2) for...
