Your furnace filter collects all that bad stuff filtering through your home’s HVAC system. The types of things collected in the filter—and these will depend on the filter type—are contaminants. Allergens and other nasties combined with particles of dust and debris. When you have a furnace filter in place, it prevents some or all of these contaminants from getting pumped, invisibly, throughout the house. The list of air pollutants in the house is varied, and very possibly seasonal, but the most common are: dust mites, dander, pollen and allergens, fumes from chemicals and auto emissions, and even mold spores.
Which Furnace Filter Should I Buy?
Filters are all different. Some filters, traditional-style and inexpensive, handle traditional problems. These are not high-efficiency filters capable of collecting every possible contaminant—there are modern filters that can even collect and remove bacteria and viruses. Of course, you don’t necessarily need one of these do-it-all filters, but if you are someone who suffers from seasonal or pet allergies, then you may want to find a type of hepa-filter at least capable of removing allergens. Also, you may pay a little more for a higher efficiency furnace filter, but the extra cost will hopefully be recouped in energy savings.
The most important part of a filter is that it gets replaced, semi-often. A dirty filter can wear on your HVAC system, hurting your system and costing you more in energy costs. Most filters have a recommended life span included on the packaging, but if not then abide by these simple timelines: conventional filters should be replaced every 1 to 3 months, while high-efficiency filters will last 6 months; longer in some cases.
To prevent yourself from forgetting the lifespan of the filter, write on the filter the exact date when you put it in place. That way if you are wondering if it’s time to replace it you can always consult the filter. Also, setting reminders in your phone or writing an arbitrary date on the year’s calendar should, hopefully, help you to remember.
Remember also to have your HVAC system serviced! We’re at the end of wintertime now, which means that in just a few short months it will be time to turn on that cool air—believe it or not! So, make sure to call R&T Services to service that HVAC system soon.
