Every year around spring is a great time to change out your furnace filter, that has accumulated dust from the air conditioning and heat you’ve used throughout the year.
High-grade filters are the most efficient way to clean the air in your home. But what do they look like when they’ve done their job? When it’s time to change your filter — anywhere from 1 to 3 months after you installed a fresh one — it should look dirty.
A build-up of dust is usually apparent, there should be gray, ashy-looking material on the duct side of the filter.
Your home environment and how often you run the heat or air can also affect how quickly your air filter gets dirty. If your home is well sealed, you have no pets, no dust-prone furnishings like carpet and fabric-covered furniture, and you dust and vacuum every day, your air filters will have fewer air-born particles to collect. Also, the system only filters the air when it’s running. If you install a new filter, but don’t turn on the heat or air conditioning until a month or two later, the filter should still be relatively clean since the system hasn’t been forcing air through it.
Making sure that you have a clean filter makes sure that your family will be breathing in clean air. Lowering health issues that could arise from all the unwanted particles inhaled.
Since you’ll be out and about taking care of the filter, don’t forget to change your smoke detectors batteries at the same time.
