Poisonous Air

Your heat or air conditioning is probably spewing mold and bacteria all over your house!

If you have central air or forced-air heating, chances are it's not filtering out all the junk it should. Less than 10% of us have the right kind of filter, and even shelling out big bucks doesn't guarantee the best kind. The cheapest and easiest way to improve the air quality in your home is to get a really good DISPOSABLE filter. The fiberglass panel filters most of us use aren't enough. The best kind is a pleated filter, rated MERV 8 or higher. You can get them at most big home improvement stores.

Don't pay extra for the filters that are washable and reusable, stick with the disposable. Experts say there is just no way to really get them clean enough. Replacing filters every three months will give you cleaner air, and save you money! Dirty filters force your system to work harder.
