Quick question just want to make sure I got it correct. I can have a lower cfm fan than my filter and be fine correct? Like my fan is like 200cfm, but found a filter bigger than I normally get thats way cheaper. I think it's someone who has no need for it and selling lol. The fan is 450cfm, will my fan still work with it? I know you cant do the opposite with fan being bigger than filter, but this should be fine just last longer correct? Anyone can confirm or deny please let's here it. Thanks in advance.
