In Orlando, as anywhere, a rotten-egg smell in the shower is usually hydrogen sulfide. Hot water only: the water heater is the usual source. Hot and cold: find the source first, since sulfur bacteria in the plumbing or a water softener can also cause it, and each needs a different fix.
- Hydrogen sulfide in hot water often comes from a reaction with the water heater's magnesium anode rod (Minnesota Department of Health).
- Our shower filter is not tested for hydrogen sulfide; it targets chlorine and chloramine.
Our pick: if you also want the chlorine out of your shower, the Second Showerhead ($99, or $79 on subscription): its Vitamin C filter cut free chlorine and chloramine by 99.9% in independent lab testing, held through Day 1-60 in our testing.

FAQ
Do shower filters actually help with skin and hair?
Yes. Filtering chlorine and chloramines from shower water can reduce dryness, irritation, and damage to both skin and hair.
How often should I replace a shower filter?
We recommend a new Second Shower filter every 60 days on the Showerhead and every 30 days on the Showerhand, or sooner if the filter looks deep brown or black or the water pressure drops noticeably.
Can I install a shower filter in a rental apartment?
Yes. Second Shower is renter-friendly: it installs in about a minute with no tools and no permanent plumbing changes.
What makes Second Shower different from other filters?
Second Shower uses NSF-certified Vitamin C filtration that removes 99.9% (during the cartridge's peak performance window, Day 1–60) of chlorine while maintaining water pressure — engineered in Seoul for performance and design.
