As a frequent help provider in [city], or of [type of help], or both, or someone who needs help and keeps checking FP for anyone offering the help they need, where they need it, I don't want to go over the process of setting those filters every time I open the app. This could be solved with:

• Never clearing filters unless the user explicitely does that.
• Allowing the user to create and save a set of filters that stays as default, or if they change some variable for a different search, they can just click back on their prefered filter.
