Free shipping for ALL orders within the continental United States.

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

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

Unfortunately, at this point 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.

Ordering bulk quantities?

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 offer an incredibly flexible return policy. If you are not 100% satisfied with your purchase, we are happy to accept unused items for a full refund (including the outbound shipping cost) for up to 90 days after your item was ordered. We realize that some times you order filters for replacement in the future and the traditional 30-day policy is simply not enough time for you to try out the product. In addition to the full refund within 90-days full return policy, we will accept returns for store credit on unused items for up to 1-year.

Order the wrong size?

One of the most common customer service issues that we deal with is a customer ordering the wrong size. We know that this can be a frustrating experience as returning filters (which are often bulky) can be a costly proposition. If you need to return a filter due to ordering the wrong size, we will offer you a 5% discount on your next order. If you ordered the wrong size the first time as part of our recurring purchase program, we will even pay your return shipping, ship out the correct size, and correct your sizing for future orders. Yet another reason to set up your filter purchases on our recurring filter program.
