Using Furnace Filters To Your Advantage
One of the simplest but most effective areas of furnace maintenance is the filter. Using furnace filters correctly will improve heating system performance, boost your indoor air quality and reduce your overall heating costs. Here are answers to some questions on using air filters that will help you make the best of these heating system components.
Why use a furnace filter?
Air filters help keep your indoor air clean and free of particulates and other pollutants. They trap and hold dust, mold, pollen and other material as air flows through your heating system. Higher efficiency filters capture even more of these contaminants and can also remove odors, smoke and biological contaminants such as bacteria and viruses.
When should I change furnace filter?
Monthly filter changes are best if that is feasible. If the filter stays relatively clean, you can leave it in the furnace for about three months. Be very careful that the filter does not get dirty and clogged. Dirty filters are a primary cause of furnace malfunctions and breakdowns.
Can I use any type of furnace filter?
In most cases, a commercially manufactured filter from any maker will work perfectly well in your furnace. It’s not necessary to use a filter made by the same company that manufactured your furnace.
What kind of filter do I need?
Different furnaces may require a different size or type of filter, so there is no one right answer to this question. You may prefer a high-efficiency filter that traps more contaminants, or one that helps control odors. Consult the owner’s manual for your furnace, or ask experts such as your HVAC provider, furnace manufacturer or filter supplier.
What does MERV mean?
MERV stands for Minimum Efficiency Reporting Value, an industry-accepted standard of filter efficiency. MERV numbers range from 1 to 16 for standard filters, with higher MERV meaning better filtration.
