It's often said that some people have no filter. Well, they do if they own a home. Most homes have multiple devices with filters that, if neglected, can negatively impact energy efficiency, comfort and equipment performance. Proper filter maintenance can reduce your energy bills and repair expenses and make your home more comfortable. Here are some filters around your house that may need your attention.

1. HVAC filter

Your HVAC filter is responsible for trapping dust pollen, and other airborne particles and keeping them from circulating throughout your home. A dirty filter can also reduce HVAC system performance and efficiency. Check your HVAC filter monthly and replace it regularly according to manufacturer's guidelines to ensure proper airflow and indoor air quality.

2. Dryer lint filter

The lint filter in your dryer should be cleaned after each use to prevent fire hazards and maintain proper airflow. Neglecting to clean the lint filter can reduce the dryer's efficiency as well. Also, inspect and clean the dryer exhaust vent at least once a year.

3. Refrigerator water filter

If your refrigerator has a built-in water dispenser or ice maker, it likely has a water filter that needs checked and replaced regularly. This helps remove impurities and maintain the quality of your drinking water. Many refrigerator models have a built-in filter change indicator light or display. Decreased water flow or a foul odor or taste could also be signs that your filter needs replaced.

4. Range hood filter

Range hood filters collect grease, smoke and cooking odors. They should be cleaned or replaced regularly to prevent buildup and ensure optimal ventilation. Most range hood filters can be easily slid or popped out from the underside of the hood. Remember to disconnect the power supply before beginning work. Clean the filter thoroughly and let it dry before reinstalling. Consult your owner's manual for specific cleaning instructions.

5. Dehumidifier filter

Many dehumidifier models come with a filter that removes impurities from the air and helps to keep internal components clean and functioning efficiently. The type of filter depends on the model. Some models have reusable filters that can be washed and reused, while others have disposable filters that must be replaced periodically. Check the owner's manual to see if your unit has a filter and how often it needs cleaned or replaced.

6. Vacuum cleaner filter

Both bagless and bagged vacuum cleaners have filters that need to be cleaned or replaced regularly. These filters trap dust and allergens, so regular maintenance ensures efficient cleaning and prevents clogging. Your owner's manual should include instructions on how to properly clean or replace the filter in your unit.

7. Air purifier filter

If you use an air purifier in your home, the filter is essential to ensure its effectiveness in cleaning the air. Different models have different filter maintenance requirements. Some air purifiers have filters that are washable and replaceable, while many models have filters that must be replaced at regular intervals. Check manufacturer's instruction on filter maintenance guidelines for your model.

8. Faucet aerator

Faucet aerators are small attachments that control the flow of water from faucets. They can become clogged with mineral deposits over time. Regularly checking and cleaning them ensures smooth water flow and conserves water. WaterSense®-certified faucet aerators are independently tested to save water while still providing a comfortable flow.

With these simple maintenance tips, you can keep dirty or neglected filters from straining your household budget.
