Why Filterbuy is the "Best Value In Town”

Frequently Asked Questions

What are the pros and cons of using cheap versus expensive air filters?

Cheap filters protect your HVAC from large debris but do little for air quality. More expensive, high-quality filters last longer, capture finer particles and reduce strain on the HVAC. This saves money in the long run.

Can a higher-MERV filter help me save on energy costs?

Yes when matched correctly to your HVAC. A higher MERV filter (like 8, 11 or 13) captures more dust and allergens. This helps keep coils cleaner and improves efficiency. That lowers energy use and extends unit life.

Which brand of air filter is considered the best?

Technicians often recommend brands that balance performance, fit and availability. Popular US made options include Filterbuy. The “best” depends on your HVAC size, MERV needs and budget.

How does a MERV 11 filter compare to a HEPA filter?

For homes, MERV 11 is better because it fits standard HVAC units without over restricting airflow. HEPA filters capture more particles but often require special equipment or bypass systems to avoid airflow issues.
