Ruby on rails ecommerce from scratch.Save product filter options for a non logged in user

I am building an E-commerce website on ruby on rails from scratch.

My product belongs to a subcategory which in-turn belongs to a category.

My filters partial include multiple check-boxes for category,subcategory,additional_category(Like hand made clothes,factory built etc.),lifestyle(relaxed,corporate etc) and cloth_material_type(this has around 30 options)

I am sending an array for each of these 5 cases to the backend to search through the associations.

Now when a non logged in user reloads the page the filters set by user resets to default.

To avoid this I have three options in mind.

Option 1. Store the filter values set by the user in the cookies which is fast.But it might slow down the user's browser.

Option2 . Store the values in a session using ActiveRecord::SessionStore gem which will increase the size of session for me to 65K but would slow down the application.

Option 3 .Using jquery modify/create document.url options so that every filter option gets appended to the document.url and on reload I get the parameters set by the user for filtering.But this looks very cumbersome to implement.

Can someone guide me which would the best way to store temporarily these details for a non logged in user.
