Frequently Asked Questions
What size air filter do I need?
Match the replacement filter to the exact nominal dimensions specified for your HVAC equipment or existing filter. Confirm length, width, thickness and required MERV rating before ordering. Do not substitute a different size solely because it appears close.
What does the MERV rating mean?
MERV is a filtration-efficiency rating. Higher MERV ratings generally capture smaller airborne particles, but the correct filter must also be appropriate for the airflow requirements of your HVAC system. Follow the equipment manufacturer's filter and airflow requirements.
Is this filter sold individually or by the case?
This product is sold as a Case of 12. One quantity at checkout represents one complete case containing 12 filters.
Is this filter available to order online?
Products with an active Add to Cart button are offered for online purchase. Availability and fulfillment timing can change by supplier, fulfillment location and destination, so an online listing should not be interpreted as a guaranteed real-time warehouse inventory count.
What are the return and shipping terms?
Shipping cost and available services are determined during checkout. Return authorization is required before sending any item back, and eligibility depends on product condition, packaging, use or installation status, and applicable supplier or manufacturer restrictions. Review the
HVACProSales Shipping & Return Policy for current terms.
