How often should I change my air filters?
Pleated air filters should be changed at least once every 3 months.
Carbon filters should be changed at least once every 3 months.
Austin Air filters can last up to 5 years.
Metal mesh filters should be washed monthly.
If you have a whole-house air cleaner, they vary, so please check your model for details.
Higher MERV filters sound great! What's the catch?
Because the filter media is denser, your system will have to work harder to pull the air through a higher MERV rated filter. Higher MERV filters may not be appropriate for old systems, or ones which are too small for the house. If your system is slower, louder, or less effective than it should be, you may want to consider a lower MERV filter.
Where are the throwaway fiberglass/polyester/mesh filters?
Polyester and fiberglass throwaway filters are becoming less common as more and more organizations realize that low-MERV filters are inadequate for protecting people from harmful air contaminants which can cause or exacerbate health conditions. Many organizations now recommend a minimum of MERV 8 for homes, schools, and offices.
We do, however, still carry throwaways for use in special situations where lower resistance or extra airflow is required. Please contact us for more information.

Are your products made in the USA?
Most of them are! ALL of our pleated air filters are made in the USA, as well as the Austin Air purifiers and their filters. Look for the Made in the USA sticker on the product's page.
How do I find my filter size?
Option 1: If you look at your old filter, the dimensions and/or part number are likely printed on the frame.
Option 2: Measure the inside of the opening of your return where the filter goes. This is the size filter you need.
I need a size not listed on your website.
Yes, we do make custom sizes. Please contact us for pricing. We look forward to working with you!
Why is my filter smaller than the size I ordered?
Each filter actually has two sizes that describe it: the size of the return opening it fits in, and the exact measurements of the filter itself. The filter needs to be slightly smaller than the return frame so that it will fit easily. Our filters are listed by return size, and the exact measurements are included in our listing descriptions.
How will I know when my order has shipped?
We will send you an email with tracking information.
Can I get a bulk discount?
If you are a business customer, please contact us.
Can I get just a few filters? I don't need a whole case.
Sorry, we don't sell individual filters, for several reasons:
1. You have other things to do with your time than order filters. They don't go bad.
2. Your cost per filter is better for case quantities because it divides the shipping cost between as many filters as possible.
3. Our prices are already low.
4. We guarantee the quality of our products.
