Choosing an ideal filter is key to your indoor breathing environment. A good filter will not only provide effective heating and cooling, it will also make it more efficient. The absence of proper air filtration may have costly, and or serious ramifications. It may increase the maintenance or consumption costs alongside reducing the longevity and comfort. Some items to pay attention to:
Some filters are located directly in the heating system intake, whereas some are placed in the furnace itself. Check the furnace manufacturing specs first to determine the type of filter setup in advance to make sure you know what you are looking for.
2. Identify the direction of air flow through the filter:
Generally, most filters flow air from one direction. It is important to follow the air flow setup to make sure the pleats don't cave, or collapse as they accumulate dust and debris.
3. Take out the old filter and place it into a garbage bag immediately to avoid dispersal of dust and debris:
Turn off the furnace to ensure your safety and to prevent blowing unfiltered particles through your duct system while you are installing the new filter.
A Few Tips to remember when choosing a furnace filter:
Even if after all this, you suspect that the air you are breathing still carries an abnormal amount of airborne particles, or presents specific health concerns, you probably want to think about contacting your local duct cleaning service.
Always remember to check your manufacturer's manual for correct sizing and ratings before you purchase your new filter. It will save you time, money and aggravation.
