When did you last think about your furnance filter? I thought as much!
3M, which makes Filtrete furnace filters, has some tips for maintaining healthy air in your home.
Another thing you can do ensure your home is safe, cozy and warm in winter is to make sure there’s proper ventilation. (See below for other tips.)That can be a challenge, especially in newer, more tightly sealed homes. Ventilation is a complex issue, but the CHMC has good information.
Change your furnace filter every two to three months. Sign up for Filtrete's email reminder service, because it's so easy to let this task slip your mind.
Not sure which size of furnace filter you need? Check your filter's manual. Manual missing? Measure the opening where the filter goes to get a good idea of the size you'll need.
Choose a filter made of polyester melt-blown fabric. According to the folks at 3M, fibre glass and washable filters aren't able to capture microparticles --- since they were originally developed to protect your furnace, not clean your home's air. Choose an electrostatically charged filter with polyester melt-blown fabric. They do double duty by improving your indoor air quality by attracting and capturing allergy-aggravating microparticles and help keep your furnace equipment clean.

Thanks for caring but my heater hasn't been used in quite a while because it is too warm. Even the windows are open at night and when it does get cold, I layer on clothing. BTW I checked the filter and its fine. Have a nice weekend.
