Autumn is here, and that means raking leaves, pumpkins, chilly weather, and more time spent indoors. As the cooler temperatures roll in, it’s also time to turn up the thermostat. But before you do, you probably need to replace that furnace filter! Most filters on the market need to be replaced at least every three months, and should be checked monthly throughout the season. If neglected, your furnace has to work harder to push air through a clogged filter, and you may be recirculating some nasty particulars, such as dust and pollen. Save yourself bouts of sneezing when the heat comes on by attending to the task now! Make sure to write down the size dimensions before you head to the hardware store to pick up your new filter. Better yet, order a multi-pack online and save up to 35-45% over the cost of local retail stores.

For optimal filtration you should choose an electrostatic filter. Dust particles often carry a small electrical charge, and the filter simply offers the opposite charge and so draws the particles statically. These don’t cost much more than the basic fiberglass panels, and work so much better. If there is someone in your home that suffers from allergies or asthma, there are many available that will help reduce the particles that may set off an attack.

For a more ecological method, you may want to consider washable filters. These are generally guaranteed for life, and are as effective at trapping dust and allergens as most other products available. For the same price of about five disposable filters, you could have a product that will save you time, money, and keep the Earth cleaner: most on the market these days simply fit into the existing space – no system modification required! They are simply cleaned with a hose, just be sure to dry thoroughly before putting them back in the furnace.

To change your filter, first turn off the furnace. Inspect the area around the unit: if you see dust bunnies or cobwebs, sweep or give it a once over with your vacuum, so that you won’t be introducing any extra dust into the system while you are changing out the filter. Then carefully slide the old filter out and dispose of it (preferably in a receptacle located outside), and replace with the new filter, paying attention to which way the airflows, and the directional arrows on the filter itself. Now you’re ready to turn the system on and warm up your home, sneeze-free!
