100% Free U.S. Shipping

Shipping & Returns

Free shipping for ALL orders within the continental United States.

We offer free shipping to the continental United States for EVERY order on FilterBuy.com.

Expedited shipping

At this point, we do not offer rush shipping on any of our orders. We simply are not equipped to offer this service at this point in time and given the cost of the rush shipping relative to the underlying items (air filters are fairly cheap but bulky!) it very rarely makes sense from a consumer perspective to pay for expedited shipping. That being said, we aim to please our customers and if you have a unique situation that requires your order to be expedited, simply contact us and we will do our absolute best to accommodate it.

Shipping outside of the continental United States

At this time, we only ship to the continental United States. Much like the expedited shipping, it very rarely makes economical sense to ship filters outside of the continental US as the cost to ship the filters internationally (or to Hawaii and Alaska) is prohibitively expensive relative to the cost of the underlying product. However, we do believe that our business model and filter manufacturing process is unique and aim to be expanding internationally in the future – we will certainly keep you posted.

Bulk Ordering

We have a large and growing wholesale filter business. If you order $1000 or more of air filters at a time, visit our wholesale page and submit an application to buy at discounted bulk pricing and save on freight shipping rates.


We understand that the traditional 30-day policy is not always enough time to decide if our filters are right for you! If you are not 100% satisfied with your purchase, we are happy to accept unused items for a full refund within 90 days after your item was ordered.
