Frequently Asked Questions
Everything you need to know about keeping your home air clean and your HVAC running smoothly.
How often should I replace my furnace filter?
For most standard 1-inch filters, we recommend replacing them every 90 days. However, if you have pets, allergies, or a large household, you may need to change them every 30 to 60 days for optimal air quality.
What is the difference between Nominal and Actual filter sizes?
The nominal size is the rounded dimensions printed on the filter (e.g., 20x20x1), while the actual size is the precise measurement of the filter. Always check the actual dimensions to ensure a snug fit in your furnace slot.
What MERV rating should I choose for my home?
A MERV 8 filter is great for basic dust and lint. MERV 11 provides better filtration for pet dander and pollen, while MERV 13 is recommended for capturing bacteria and smoke particles without restricting airflow in most modern systems.
Do you offer subscription services for filter replacements?
Yes! You can sign up for our 'Set & Forget' subscription to have your filters delivered automatically on your preferred schedule, ensuring you never forget a filter change again.
What is your return policy for incorrectly ordered sizes?
We offer a 30-day return policy for unopened and unused filters. If you accidentally ordered the wrong size, please contact our support team to initiate an exchange for the correct dimensions.
How long does shipping take?
Orders are typically processed within 24 hours. Standard shipping usually takes 3 to 5 business days depending on your location within the continental United States.
