I assume your talking about under gravel filters in aquariums. There really is no right or wrong answer to this question. It's all about personal opinion. It really depends on what type of set up you have. In my opinion it is completely fine to have a under gravel filter, it is also unnecessary. If you have an adequate hang on back filter and do proper water changes you will not need this extra filtration. Some think it is nice to have anyway, they say it helps get water flow under the gravel and builds better biological bacteria helping break down the toxins that accumulate. So the ultimate answer is... It's up to you ;) I'm sure this answer is pretty much no help but I have no background information to be specific to your tank, if you want to start a discussion I'm more than happy to answer specific questions. Or find a knowledgeable person at your local aquarium shop to help you out.
