Does a air filter in a outlet fan really nesessary

[Cankur.007]

My case has got 6 fan support 

Front 2

Back 1

Bottom 1

Top 2 

So the front will obviously be pulling air into the case and rest all will be pusing out air

I m not putting any fans on the top for now however my query is do I need to put air filters on the exhaust fans also as my case front panel has air filters by default for the front intake fans so I don't need to buy them extra 

Are air filters also important for exhaust fans cos they don't take anything in so nothing dusty will go inside

Whats u guys think of this ?

I believe that as long as there are more intake fans than outtakes, filters are not needed on outtakes.

You don't need filters on your exhaust fans. Just the intake ones. Just be mindful to inspect them when you're doing your routine cleaning in case they need a quick wipe down.

Ok what if I m leaving a vent for 1 or 2 fans due to unavailablity of fans then do I need to permerantly close thenm may be with tapes or increase the +ve pressure in side the case by using more intake filtered pans or just use s air filter there too
