## Questions & Answers

**Q: What are the actual dimensions of the 6" filter?**
A: Hi,
Thanks for your concern.
Below is the size information for MARS HYDRO 6 inch carbon filter:
Opening: 6", Length: 8.27"

Hope this can help you.
Thanks

**Q: How often do you recommend replacing this filter?**
A: I would just go with a 6 inch carbon filter that way it pulls out more air if a 6-in can fit than a 4 in and if you get the 6 in replace it maybe once a year depending on how much you use it and how hard you're running it

**Q: Does this 4 inch filter hook up to a 4” duct ?**
A: Hello,
Thanks for contacting us.

Yes, you can use the MARS HYDRO 4 inch carbon filter with 4 inch ducting and inline fans.
Hope this helps you, please feel free to contact us with any questions.

Best Wishes,
