Furnace Filter Replacement Schedule: 4 Ways to Remember When to Change Them

According to the World Health Organization, 4.3 million people per year die because of indoor air pollution. The problem isn’t as acute in the developed world, but most people would be surprised at the sheer number of indoor pollutants in their homes: exhaust fumes, mold, mildew, pet dander, viruses, bacteria, pollen, and more are all floating in the air we breathe indoors. Having the right filtration in your home’s HVAC system, and ensuring the filter’s changed often enough, is simple with an assist from Ace Plumbing.

Why Change Your HVAC Filter?

If you still need to be convinced after reading the list of pollutants above — the ones that a good filter will keep out of your air or help to minimize — there are other reasons to change your HVAC filter. If you have pets in your home, one or more occupants of the home are smokers, or if you’re in the habit of keeping your windows open, your filters will need to be changed more often.

When Should You Change Your HVAC Filter?

Technically, your filter should be changed every three months. However, as we’ve already seen, there are a number of factors that could mean more frequent changes. Our advice? Check monthly. A coating of dust is common, but you should still be able to see the filter material. If there’s more dust than filter visible, it’s time for a change.

How Am I Supposed to Remember That?

There are a few simple ways to remember when to change your HVAC filter.

Write it Down

The shortest pencil is better than the longest memory. If you’ve got a day planner, or even just a calendar hanging somewhere, jot down a monthly reminder.

Set a Reminder

Your smartphone’s calendar feature will let you set reminders. Use it. You can also install an app that can remind you.

Pay the Bill, Check the Filter

You’re paying for the gas or electric that keeps your HVAC system running. When the bill arrives, or when you get the autopay reminder via email, use that time as a reminder to check your filter.

In Sight, In Mind

Is there a part of your house you visit frequently? Keep a few replacement filters there as a reminder, whether it’s your workbench, your garage, or the laundry room. Don’t worry, there’s no harm in checking more often!

What Kind of HVAC Filter Do I Need?

The most important thing is to be sure it’s the right size for your HVAC unit. A close fit isn’t good enough; it needs to be the right fit. Gaps in coverage can lead to damage and HVAC repairs, and will keep the filter from doing what it’s designed to do. We also recommend pleated filters; they’re a bit more expensive, but the increased surface area makes them more effective at their job.
