Size not accurate.

This item measures 4-3/8", not 4" and will not fit into my furnace. I am very disappointed because I trust this to be a great filter.

reply from Customer Engagement Center

Thank you for taking the time to share your feedback on our Filtrete™ 4" Filter. We sincerely apologize for the frustration you've had with this filter. Because our 4" filters can be used and will offer the same performance in housings that accommodate 5" or thicker filters, our filters are over cut by 3/16''. So, though the nominal width of this filter is 4'', the actual size is 4-3/16''. If you have further questions, you can call us at 800-494-3552 and mention case number 6167574 so we can help. We're available Monday-Friday, 8am-5pm CT and look forward to speaking with you. We've also sent you a direct email with this information. Thanks!

Always buy these and always change them every 90 days. They trap a multitude of particles!
