do these work on falsken heater treater? do you change it once a year?

Hi, Thanks for your questions. The length of our filter is 20 inches(about 508mm), the outer diameter is 2.5 inches (about 63mm), the inner diameter is 1.1 inches (about 28.5mm). If the size of Falsken Heater Treater is the same as our filter, it can be work. It's time to replace the filter when there is a significant drop in flow rate. The lifetime is depending on the quality of the original water source and application type. Suggest following the change-out cycle we recommend to avert re-contamination of filtered water. If you have any questions, please feel free to contact us. Best Regards, Membrane Solutions

The gallons per minute flow rate based on what pressure of water? Thanks

Take a 1 gallon container and time how long in seconds it took to fill it(do it several times and take an average). Next devide 60 by by the average time it took to fill the 1 gallon container.-60/ the number of seconds.

Do these filters work with aqusana whole house well systems?

I am not familiar with this type of water system but if you have a 2 in half by 20 inch filter housing then these will help reduce sediment from incoming city water.
