That will depend on your voice and mic technique. The internal filter might be fine. You can make an external pop filter by stretching a nylon stocking over a circle of coat hanger wire if you feel you need one.

Thanks. But if I would use 2 filters (the built-in and an outer one), will it worsen the quality of the audio? Or a pop filter doesn't worsen the quality at all?

I suppose that anything designed to filter plotives affects the audio quality in some way, but pop filters are pretty darned transparent. Putting an external pop filter on a mic with an internal filter is done all time. If you feel the mic is good for your situation, I'd just get it and see if you have problems with popping your p's. If you do, you can experiment with filters (and work on you vocal technique).

Thanks :) So what does it mean, I don't need an outer pop filter?

no to the second pop filter hurting your sound, and up to you on outer pop filter, never hurts

Thanks very much!

I think I will buy one, because it is cheap.

But there are so much pop filters out there. I don't know what kind of pop filter can I use for Rode Podcaster. What should I looking for when I choose the pop filter? Should I simply choose an "universal pop filter"?

doesn't matter pop filters do the same thing

Personally, I prefer foam pop filters for handheld rock-and-roll PA microphones.

I think foam pop filters are also perfectly fine especially for use on spoken word, broadcast/podcast announcer work. The 1/2 DB loss at 15kHz just is not a factor to be concerned with. In fact, I find it useful for spoken word purposes.

I like the nylon stocking/embroidery hoop, aluminum punched frying pan splatter screen lids (Stedman high-priced for writing) to be better on singers in the studio. Because it is truly an external device, it really allows you to position the respective talent from a preset distance of your choosing. That way, they can't get too close. Whereas a piece of foam reduces that distance to less than 1 inch on average. With the screen, the performer is typically 3 to 8 inches from the actual microphone capsule. Not completely applicable or feasible for close proximity announcer/interview radio use.

Foam can also be used to prevent pregnancy. Remember kids, always put a condom on your microphone especially in the rain.
