Tips For Maintaining Your Furnace Filter
Here are 4 things you will want to know about your furnace and it's filter.
1. Check & change your filter on a regular basis
The length of time each filter is good for varies and depends on the exact filter you’re using. We recommend always following the manufacturer's guidelines. Generally speaking, a 1-inch thickness filter is good for 30 days and a 4-inch thickness filter is good for 3-6 months.
2. You need a proper fitting filter
Your furnace filter should fit JUST right in the filter slot – with no gaps on either side. Having a gap means not all the air circulating through your furnace will be filtered due to the fact that air takes the path of least resistance.
3. Should I pay attention to the MERV rating?
An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. A good Merv rating for residential use to balance filtration vs airflow is between 5 and 11. A higher MERVE rating and your furnace may not be able to handle the decrease in airflow. If your filter slot fits a filter size bigger than 1″, using a filter with a higher MERV rating isn’t as much of a concern due to the more surface area a thicker filter has (less resistance to air).
4. Run your furnace fan, even when you’re not heating your home!
To keep continuous airflow and filtration in your home, have your furnace fan turned on. If you’ve never done this before, you’ll have to check on the state of your furnace filter more regularly as your filter will be pulling more air through it and filtering more dust and debris.
