Water Saving Ultra Low Flow Aerators

by Neoperl®

These low-flow aerators can be used to quickly and easily replace your existing faucet aerators to convert your water wasting faucets into environmentally friendly, water saving faucets. If the water flow rate from your faucet is more than 1.5 gpm (gallons per minute), you should replace your aerator with a more high-efficiency water flow rate aerator to not only reduce water waste but to save you money.

These Water Saving Aerators features:
  • High precision flow aerators for drinking water conservation
  • Proven first class quality construction and plating
  • Simple, low cost faucet flow transformation for optimum water usage
  • Ultimate low flow rates of 0.35 gallon per minute
  • Ultra low flow rates of 0.50 gallon per minute
Note: Tankless water heaters require a minimum flow rate in order to turn on and heat the water. When deciding which aerator to use, choose an aerator with the correct flow rate to allow your tankless water heater to activate properly.

Choosing the Right Aerator

Image of Male threads versus Female threads
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 15/16" x 27 thread Male or 55/64" x 27 thread Female) will be roughly the diameter of a quarter
  • A Junior size aerator (aka 13/16" x 27 thread Male or 3/4" x 27 thread Female) will be roughly the diameter of a nickel
  • 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.
