How does pricing work?

Every size 1-inch filter is the same price - we tried to make it simple! Your first filter will cost only $14.99 (that is just $5.00 per month if you are on the 90 day delivery plan).

Every time you add a filter, the price of every filter goes down, if you buy...

You get the idea.

Does it matter how often I change my filters?

Absolutely! Do you remember the last time you changed your air (or furnace) filters after a longer than normal time interval? Did you notice how dirty they were? Well, when they get that dirty, it causes your AC and heating system to have to work harder and thus less efficiently. One way or the other, it will cost you money replacing or repairing your AC or heating system as well as paying higher energy bills. It just makes sense to change your filters ON TIME with AirFiltersByMail.com "remembering so you don't have to". Read what the experts say.

How do I size my filters?

Most of the time the size of your air filter(s) are printed on your current filter, if not, a brief explanation is required. Just like a 2"x4" piece of wood is not ACTUALLY 2"x4" anymore, so goes the measurements of an air (or furnace) filter.

There are actual dimensions and nominal dimensions. The actual dimensions are the lengths the tape measure tells you but nominal dimensions are the ones listed on the air filters. For example:

An air filter might have the actual dimensions of 23-1/2" X 23-1/2" X 1-3/4" but will be labeled as a 24" X 24" X 2" filter. The actual dimensions are usually 1/8" to a 1/2" smaller than the nominal dimensions (or those printed) on the filter.

So when choosing your filter size (and no dimensions are listed on your current filter), measure the filter or opening the filter sits in and choose a filter with 1/8" - 1/2" dimensions larger than what you measured. If none of our choices match, then provide us with your custom filter sizes (actual measurements) and we will have them made for you - Click Here for this service.

Why are only MERV 8 filters offered?

Thanks for asking. We are a new company and wanted to make sure that we could offer a quality product, at a good price, with the best service. The way to help insure these goals were met was to SIMPLIFY in the early stages of our company's life. We want to keep things simple at first but we plan to grow quickly so if you like the idea of us "remembering so you don't have to" then order now and you can easily upgrade to a higher MERV rating at a later date. We hope to soon make MERV 11 filters our next filter we sell using our unique subscription filter service (charges may apply for upgrading).

Will you ever provide any other products via your subscription service?

We sure hope so! If there is a product that you want us to offer, please let us know. We would love to hear from you.
