Maintaining Your Furnace: How to Change Your Filter Right

Keeping your home's heating system in top shape requires regular maintenance, and one of the most important steps is changing your furnace filter. Not only does this help keep your furnace running efficiently, but it also helps ensure that the air quality in your home is safe and healthy. Here are some tips on how to change your furnace filter correctly.

Selecting the Appropriate Filter

The first step in replacing your furnace filter is making sure you choose the right one. Different filters are designed for different levels of filtration, so it's essential to pick a model that meets your needs. If you have allergies or asthma, you should opt for a filter with a higher MERV rating - Minimum Efficiency Reporting Value - which indicates how effective it is at trapping particles like dust, pollen, and pet dander.

Checking the Size

Once you've selected an appropriate filter, make sure it fits properly by checking its size against that of the existing one. Most furnaces will have a label indicating what size should be used; if not, measure both length and width before buying a new one.

Replacing the Filter

When ready to replace the old filter with a new one, start by turning off power to the furnace. Open up its access panel and take out the old filter; note which way it was facing so you can install its replacement in exactly the same direction. Insert the new filter into place then close up the access panel again before turning power back on and checking everything works as expected.

Cleaning Up Afterward

After replacing your furnace filter, make sure to clean up any dust or debris left behind. Vacuum or use a damp cloth around the access panel or other parts of the furnace, ensuring all particles are removed. This will help keep everything clean and efficient.

Scheduling Regular Replacements

It's important to replace your furnace filter regularly, usually every three months, though this may vary depending on usage. Some filters also come with indicators letting you know when they need replacing.

Conclusion

Changing your furnace filter regularly is key for maintaining an efficient heating system at home while ensuring good air quality. By choosing the right type of filter and replacing it every three months (or as needed), you can ensure that both these goals are met.
