Frequently Asked Questions
What happens if I don’t change my furnace filter regularly?
Dirty filters restrict airflow, forcing your furnace to work harder. This increases energy bills, reduces heating efficiency, creates strain on components shortening lifespan, and can cause system failure. Dirty filters also allow dust and particles to circulate in your home, reducing indoor air quality and aggravating allergies or asthma.
Can I use a higher MERV-rated filter than recommended?
Check your furnace manual for the maximum MERV rating your system can handle. Using filters with ratings higher than recommended can restrict airflow, reducing efficiency and straining your furnace. Most systems safely handle MERV 11-13 filters. Consult Whitney Services if unsure about appropriate filter ratings for your system.
Are reusable filters better than disposable filters?
Reusable electrostatic filters save money long-term since you wash rather than replace them. However, they require regular cleaning and may not filter as effectively as quality disposable filters. Most experts recommend higher-quality disposable filters over reusable options. Whitney Services can recommend the best choice for your situation.
Should I use the cheapest furnace filters available?
Cheap basic filters offer minimal filtration and need frequent replacement. Mid-range pleated filters (MERV 8-11) provide better value, lasting longer while filtering more effectively. For allergy or asthma sufferers, higher-quality MERV 12-13 filters justify the extra cost. Better filters improve air quality and furnace efficiency, offsetting higher filter costs through energy savings.
Can I go longer between filter changes if I use a 4-inch filter?
Yes. Thicker 4-inch filters have greater capacity and typically last twice as long as 1-inch filters (every 3-6 months vs. 1-3 months). They also filter more effectively, improving air quality. Thicker filters are more cost-effective long-term despite higher per-filter cost. Ask Whitney Services whether 4-inch filters fit your furnace.
