Choosing the Right Aerator

Aerator size comparison

1. Determine whether your faucet spout is female or male threaded. Female-threaded spouts have their threads inside the end of the spout; male threads are found on the outside of the spout. If your faucet has female threads, you'll need a male threaded aerator. If your faucet has male threads, you'll need a female threaded aerator.

2. Now, you'll need to find out what size aerator you require. The easiest way to do so is by grabbing some spare change: a quarter, nickel, and dime. You'll compare these coins to the size of the threaded end of your existing aerator (or the outlet of the faucet spout itself).

  • A Regular/Standard size aerator (aka M24 x 1 thread Male or M22 x 1 thread Female) will be roughly the diameter of a quarter
  • A "Tom Thumb" size aerator (aka M18 x 1 thread Male or M16 x 1 thread Female) will be roughly the diameter of a dime
Please note: the quarter, nickel, and dime are all approximate measurements. Before placing your order please double check your thread sizing. Some faucet brands use custom sizes, so if you know the manufacturer of the faucet, you can contact them for the exact aerator size.

Frequently Asked Questions

Q. "I purchased a 1.8 gpm aerator and the packaging itself indicates 1.8 gpm. However, I noticed the aerator product itself has 1.75 gpm impressed into the metal. Which GPM notation is correct?"
A. Technically speaking, the flow rate is 1.75 gpm and has been rounded up to show 1.8 gpm on the packaging. When the state of California enacted The Water Conservation Act of 2009, they were required to reduce water consumption by 20%, reducing their maximum flow from 2.2 gpm to 1.75 gpm. The manufacturer started making their aerators 1.75 gpm to be compliant with California's law. However, California chose to round the 1.75 gpm figure to 1.8 gpm maximum flow rate (and several other states followed suit in reducing their maximum flow rates to match these figures). The manufacturer did not want to confuse their suppliers and opted to label the bag as 1.8 gpm and laser mark the housing as 1.75 gpm, rather than make two entirely different products when there is actually very little variation between them.
