Showering in treated municipal water exposes skin and hair to residual disinfectants like chlorine, which can strip natural oils, cause scalp irritation, and fade dyed hair. The Afina Filtered Shower Head enters an increasingly crowded market of aesthetic shower filters, promising to target chlorine, heavy metals, and hard water minerals. Priced at $129.00, this unit integrates a multi-stage cartridge directly into a custom showerhead housing.
Filtration Performance & Lab Analysis
Evaluating a shower filter requires separating actual media capabilities from broad promotional language. Reported testing of the Afina filter involved taking pre-installation baseline water samples alongside post-installation filtered samples from municipal feed lines in Colorado, evaluating free chlorine, disinfection byproducts, and total dissolved hardness.
Disinfectant Removal
Where the Afina shower head excels is direct chlorine neutralization. On-site colorimeter testing measured an initial municipal chlorine concentration of 1.68 PPM. After passing through the filter cartridge, residual chlorine levels plummeted to 0.02 PPM—a reduction exceeding 98.8%.
This dramatic drop aligns with the physical capabilities of its internal media blend, which combines KDF-55, activated carbon, and calcium sulfite. Calcium sulfite and KDF-55 react rapidly with free chlorine even under high flow rates and elevated temperatures, making them highly effective for shower applications where contact time is minimal.
Disinfection Byproducts & Water Hardness
Marketing materials for the Afina suggest it mitigates hard water and protects against a wider array of aquatic impurities. However, lab analysis paints a very different picture regarding mineral content and disinfection byproducts (DBPs).
Baseline water testing showed total hardness at 250 PPM. Post-filtration samples recorded 251 PPM, confirming that the unit provides zero water softening capabilities. True water softening requires salt-based ion exchange or specialized scale-inhibiting media; standard KDF and carbon cartridges cannot remove dissolved calcium or magnesium ions.
Similarly, independent lab testing via Tap Score evaluated volatile organic compounds and trihalomethanes (THMs) such as bromoform, bromodichloromethane, and dibromochloromethane. The Afina filter showed no capacity to reduce these compounds. Fluctuations in feed water source concentrations resulted in higher post-filter DBP numbers, demonstrating that the short contact time inside a shower cartridge is insufficient for volatile byproduct absorption.
Design, Build, & Flow Impact
The Afina shower head features an ABS plastic body with brass connection threads and stainless steel internal fittings. Available in chrome, nickel, and matte black finishes, the aesthetic and physical build closely resemble other premium direct-to-consumer shower filters, such as the Jolie.
Despite adding filtration media directly into the water stream, flow restriction is virtually non-existent. Under dynamic operating pressures of 30 PSI, reported flow testing clocked the Afina at 1.85 GPM. This matched the baseline rate of the un-filtered showerhead, ensuring strong spray coverage without sacrificing pressure.
It is worth noting that while the build quality feels durable for plastic construction, the unit holds no official NSF/ANSI Standard 177 performance certification, nor does it carry lead-free materials certification.
Installation & Ongoing Maintenance
Setting up the Afina requires basic hand tools and minimal plumbing experience. The package includes thread-seal Teflon tape and a custom wrench contoured to fit the attachment fittings. Installation involves unscrewing the existing showerhead, wrapping the exposed pipe threads, and tightening the Afina housing into place.
Maintenance demands are straightforward but frequent. The internal cartridge has an estimated service lifespan of 60 days (two months). Swapping out spent media involves unscrewing the lower faceplate, replacing the yellow plastic cartridge, and re-securing the housing.
Financial Value & Warranty Terms
At an initial purchase price of $129.00, the Afina sits in the mid-to-high tier for integrated shower filters. Ongoing filter replacements run roughly $240 per year based on two-month swap intervals, bringing the operational cost to approximately $0.042 per gallon filtered.
Afina offers a 90-day money-back guarantee and free ground shipping within the contiguous 48 states. A lifetime warranty covers structural housing defects, but only if the consumer maintains an active cartridge replacement subscription.
The ClearCurrent Verdict
The Afina Filtered Shower Head successfully solves one major problem: it removes virtually all free chlorine from municipal shower water while preserving strong water pressure. For individuals suffering from chlorine-induced dry skin, brittle hair, or scalp redness, the unit performs admirably.
However, consumers should disregard claims regarding hard water softening or total contaminant purification. If your primary goal is eliminating limescale or removing complex organic byproducts, this filter will disappoint you. If your goal is pure chlorine reduction in a sleek, easily installed fixture, the Afina is a capable—if costly—solution.
