About Air Filters Delivered

Established in 2010, Air Filters Delivered provides HVAC air filters in over 600 standard sizes and custom measurements for residential and commercial systems. You can shop by MERV 8, 11 or 13 ratings depending on the level of filtration required. The service delivers direct from U.S. warehouses, and most orders are fulfilled within 24 hours. Subscription services are available to ensure you're never late on a filter replacement. All filters are made in the USA, and the air filters comply with the ASHRAE standards for efficiency and performance. With bulk prices and factory direct discounts, Air Filters Delivered aims to make regular maintenance more affordable.

How Do I Apply a Promo Code at Checkout on Air Filters Delivered?

  1. Choose a product: Head over to any product category, such as 'AC & Furnace Filters' or 'Custom Air Filters' and select a filter size, such as 16x20x1'. Adjust the quantity and pack size and click the green 'Add to Cart' button.
  2. Check your basket: Click the black cart icon in the top right hand corner and click 'View Cart' from the dropdown.
  3. Add a promo code: Scroll down to the 'Order Summary' section underneath the list of products. Find the 'Enter Promo Code' section. Paste in your valid code from DontPayFull and click the gray 'Apply' button to apply the code and activate the discount. If the code is accepted, the discount will be applied to your order total.
  4. Checkout: Click the green 'Secure Checkout' button. On the next page, enter your shipping and billing details to pay for your order.

What should I do if my Air Filters Delivered coupon is not working?

  • AFD subscriptions: Discount codes do not apply to auto-deliveries. If you have a subscription order in your basket, remove it and use the code on one-off purchases.
  • Check for filter size restrictions: Some offers only apply to certain filter sizes or types. Filters described as 'custom' or 'hard-to-fit' do not work with standard discounts.
  • Don't combine codes with sitewide deals: As long as the site has a percentage-off deal already running, coupon codes will be disabled. Check the automatic discount against your code and take the higher amount.
  • Clear browser cache or try guest checkout: Old sessions affect code validation. Clear your cache or go incognito. If you're logged in, try applying as a guest - some codes only work for new users.
