Views exposed filter for several fields Have 3 content types. Apartment, hotel, motel.

Each has integer field "number of beds".

Lets say user wants to see apartments that have between 10 and 15 beds.
In views for apartment i made exposed search filter adding number of beds 2 times, 1st is "greater or equal to" and 2nd is "less or equal to".

This all works fine.

Now i want to apply this filter to all content types in one view so that user after entering from 10 to 15 beds applies this search request to all content types at same time.

Solution that should work is to create 1 bed field on apartment and use that existing field on hotel and motel, but i want to have it separated so that i have control of each field in each content type separately. 

I have tried Global: Combine fields filter, but it does not support "greater or equal to", "less or equal to" etc.
Create your first view block for Apartment with the exposed filter. Create attachments for each of the other two that inherit the exposed filter. As the comments stated, as long as they used the same field this will work perfectly.
