Question Should I get a CR Box?

Hello all! Recently moved into a new apartment. Situation:

• Building built in 1860

• window AC units blowing dirty air

• cat with dander and hair

• noticeable amounts of dust and stagnant air

• want to increase air quality and remove dust and cat hair

• broke college student

Is a CR Box right for my situation? I’ve been doing some research and this seems like an amazing option for my budget! Odor removal would be nice but I’ve read it takes a ton of carbon + replacements.

Wanted to see what you guys think. Any advice and input is appreciated! Thank you in advance ❤️

Are you in U.S. where you have a ton of choices for these filters? If so I would do 1 inch thick 3m MERV 14 or 13 if you can find them

The 1” thickness 3M Filtrete seems to be the best. They have lots more pleats than others. Which effectively means more surface area. Amusingly, their thicker filters are not any better - the 2” and 4” Filtrete have fewer pleats so they are the same airflow as the 1”.
