The Truth About Furnace Filters You Need to Know
One of the most persistent myths in home heating maintenance is that expensive, high-MERV rated filters are always the best choice for your heating system. This common misconception costs homeowners hundreds of unnecessary dollars each year.
Let’s debunk this myth once and for all:
Why More Expensive Isn’t Always Better
1. Higher-rated filters can restrict airflow
2. Restricted airflow makes your furnace work harder
3. Some systems aren’t designed for thick, dense filters
4. More frequent replacements may be needed with premium filters
What You Really Need to Know
The truth is, most residential HVAC systems work perfectly well with medium-rated filters (MERV 8-11). These filters strike an ideal balance between:
– Adequate dust and particle removal
– Proper airflow maintenance
– Cost-effectiveness
– System efficiency
The Bottom Line
Unless you have specific health conditions or unusual air quality concerns, choosing a mid-range filter and changing it regularly is often the smartest choice for your furnace’s health and your wallet. Regular maintenance and proper filter changes are far more important than using premium-priced filters.
Remember to schedule regular maintenance checks to ensure your system runs efficiently, regardless of which filter type you choose. This simple step can prevent costly repairs and extend your furnace’s lifespan.
