Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
Your tap water is treated with plain chlorine and your main goal is to cut the chlorine smell and harshness during baths
You want the lowest-cost way into a bath filter and do not mind replacing the bag every two months
You want a tool-free filter that straps onto a standard horizontal tub faucet
You are reassured by an independent published lab test for the chlorine claim specifically
You mainly want a long-lasting cartridge and a no-tools faucet install, and chlorine removal is not your priority
You fill the tub very slowly and are comfortable relying on an unverified setup
You want an inexpensive entry point and plan to verify your own water separately
The main thing to know
An outside lab confirms it removes the chlorine from bath water, but the filter media is unnamed and there is no published heavy-metal or chloramine test for this specific product, so most of its safety picture stays unverified.
Independent lab testing found this filter removed no chlorine at a normal tub-fill speed and actually raised copper in the water by 405%, which is the opposite of what a bath filter should do.
Skip this if you...
Your utility treats water with chloramine, which this filter has not been shown to address
You want a named, certified filtration media rather than an undisclosed granulated material
You need independent proof the filter itself does not release metals into the bath water
You have a long vertical faucet neck, which the strap does not fit
You are buying specifically to remove chlorine from a baby's bath at a normal fill speed
You want a filter that has been independently shown not to add metals to the water
You expect a temperature indicator or soft spout cover for infant bathing
You want a filter with a recognized independent certification behind its claims
Neither of these quite what you're looking for?

Not necessarily. The overall score reflects how we weight those three pillars, but your priorities may differ. If you care most about safety, compare the safety scores directly.
