Your Lysol unscented furnace filter should be replaced every three to four months to keep your HVAC systems operating properly, improve HVAC system energy efficiency, and boost indoor air quality. To replace your furnace filter, follow these steps:
Once your new filter is in place, you’re good to go! While these filters typically need changed every three to four months, it’s wise to check them each month to ensure they have not become filled with contaminants sooner than expected – this can happen during the summer or winter when your HVAC systems are running more frequently, or if you have higher contaminant levels indoors due to pets, smoking, or other activities.
To check the condition of your furnace filter monthly, follow the replacement steps above. Instead of removing the old filter and throwing it away, simply slide it out and inspect the filter. If the entire surface of the filter is caked with brown or grey particles, go ahead and replace it; if your filter is still in good shape, simply slide it back in the cabinet and replace the access door. If you find your Lysol unscented furnace filter is becoming clogged faster, replace it more frequently.
