Top 10 Air Filter Maintenance Mistakes Homeowners Make

Keeping your home's air quality in top shape is essential for the health and comfort of your family. However, many homeowners overlook or misunderstand air filter maintenance, leading to inefficient HVAC systems and poor air quality. At Filter Time, we want to ensure you avoid these common pitfalls. Here are the top 10 air filter maintenance mistakes and how to avoid them.

1. Not Replacing Filters Regularly

The Mistake: One of the most common mistakes homeowners make is not replacing their air filters often enough. Over time, filters become clogged with dust, pollen, and other contaminants, reducing their efficiency.

How to Avoid It: Set a reminder to check your filters every month and replace them every 1-3 months, depending on usage and the type of filter. Consider subscribing to an air filter delivery service like Filter Time to ensure you always have a fresh filter on hand.

2. Using the Wrong Filter Size

The Mistake: Using an incorrect filter size can lead to poor air filtration and allow unfiltered air to bypass the filter, compromising your indoor air quality.

How to Avoid It: Always check your HVAC system's manual for the correct filter size or measure your old filter before purchasing a new one. Double-check the dimensions before installing the filter.

3. Ignoring the MERV Rating

The Mistake: Not considering the Minimum Efficiency Reporting Value (MERV) rating of your air filter can result in choosing a filter that's either too restrictive or not efficient enough.

How to Avoid It: Select a filter with a MERV rating that balances efficiency and airflow for your specific HVAC system. For most residential systems, a MERV rating between 8 and 13 is ideal.

4. Neglecting to Check for Air Leaks

The Mistake: Even with a high-quality filter, air leaks around the filter frame can allow contaminants to enter your home.

How to Avoid It: Ensure the filter fits snugly in the filter slot. Use weatherstripping or foam tape around the edges if necessary to create a better seal.

5. Overlooking the HVAC System's Maintenance

The Mistake: Focusing solely on the filter and neglecting the overall maintenance of the HVAC system can reduce efficiency and lifespan.

How to Avoid It: Schedule regular professional maintenance for your HVAC system. A technician can clean the coils, check for leaks, and ensure everything is running smoothly.

6. Reusing Disposable Filters

The Mistake: Attempting to clean and reuse disposable filters can diminish their effectiveness and introduce more contaminants into your home.

How to Avoid It: Stick to the manufacturer's guidelines. If a filter is labeled as disposable, replace it rather than attempting to clean and reuse it.

7. Forgetting to Check Filters in All HVAC Units

The Mistake: Many homeowners only replace the filters in their main HVAC system, forgetting about filters in other units like portable air purifiers or room-specific air conditioners.

How to Avoid It: Keep a checklist of all devices in your home that use air filters and maintain a regular replacement schedule for each one.

8. Using Inferior Quality Filters

The Mistake: Opting for cheaper, lower-quality filters may save money initially but can lead to higher costs in the long run due to reduced efficiency and potential damage to your HVAC system.

How to Avoid It: Invest in high-quality filters that offer better filtration and durability. Quality filters can improve air quality and prolong the life of your HVAC system.

9. Not Changing Filters Before Peak Usage Seasons

The Mistake: Many homeowners forget to replace their filters before high-usage seasons like summer and winter, when HVAC systems work the hardest.

How to Avoid It: Replace your filters at the start of the heating and cooling seasons to ensure your system runs efficiently when you need it most.

10. Ignoring Manufacturer's Recommendations

The Mistake: Disregarding the manufacturer's recommendations for filter maintenance can lead to suboptimal performance and potential damage.

How to Avoid It: Read and follow the maintenance guidelines provided by your HVAC system's manufacturer. They know what's best for keeping your system running efficiently.

Maintaining your air filters is a simple yet crucial task that can significantly impact your home's air quality and your HVAC system's performance.
