Frequently Asked Questions
How often should I replace pleated furnace filters in a high-dust home?
For high-dust environments plan on checking filters every 30–60 days and replacing them at least every 90 days. Homes with pets, construction dust or heavy outdoor particulates may need changes more often—inspect visually and replace when the pleats appear clogged.
Will a MERV 8 filter reduce airflow or harm my HVAC system?
MERV 8 is designed to balance particle capture and airflow for most residential systems. Proper sizing and not installing a filter that’s too dense for your system are key. If your system is older or has a history of airflow issues, consult an HVAC technician before stepping up to higher MERV ratings.
Are deeper filters (2" or 4") worth the extra cost?
Yes—if your filter housing supports the depth. Deeper filters hold more dust and can last longer between changes, which is valuable in dusty homes. They may cost more upfront but can save time and reduce frequency of changes.
