Pipe perfomance issue

[Rishi0405]

I observed that this pipe getting called every time and causing performance issue.
I guess this is an impure pipe, if so could you please make it pure.

Thanks,

I checked a few articles about implementing filter through the pure pipe and they mentioned it is impossible to do it through the pure pipe, also I saw in doing with an observable and async pipe, could you please check on that too. Because it caused me huge performance issue in my application.
I'm currently using it in .ts,

Thanks,
