Everything you need to know about the SYNONX shower filter. Can't find what you're looking for?
The SYNONX 4-stage filtration system removes chlorine, heavy metals (lead, mercury, nickel), sediment, rust, bacteria, and volatile organic compounds (VOCs) from your shower water. It also neutralizes chloramine and reduces limescale buildup.
No. SYNONX is engineered to maintain full water pressure. Our filtration media is designed to allow optimal flow while still capturing contaminants effectively. Most customers notice no difference in pressure after installation.
The SYNONX filter housing is made from ABS and brass. It is CE certified and RoHS compliant, meaning it contains no hazardous substances. All internal components are food-grade and BPA-free.
Yes. The SYNONX filter uses a universal 1/2-inch connection that fits virtually all standard shower arms and handheld shower hoses. It comes with multiple adapters and fittings to ensure compatibility with your setup.
SYNONX uses a proprietary 4-stage filtration process: KDF-55 for heavy metals and bacteria, calcium sulfite for chlorine removal, coconut shell activated carbon for VOCs and chloramines, and Vitamin C ceramic balls for antioxidant infusion. This multi-stage approach removes a broader range of contaminants than single-stage filters.
Installation takes about 2 minutes with no tools required. Simply unscrew your shower head from the shower arm, screw the SYNONX filter onto the arm, then attach your shower head to the bottom of the filter. Hand-tighten and you are ready to go.
No. The filter is designed for simple DIY installation. It screws on just like a shower head. If you can change a light bulb, you can install SYNONX.
Yes. The filter works with both fixed and handheld shower heads. For handheld setups, install the filter between the wall outlet and the hose connection using the included adapters.
Each SYNONX cartridge lasts approximately 6 months or 10,000 gallons of water, whichever comes first. This is based on average household usage of two showers per day.
We recommend replacing the cartridge every 6 months for optimal performance. Signs that it is time to replace include reduced water flow, a return of chlorine smell, or if your skin and hair start feeling dry again.
Simply unscrew the filter housing (no tools needed), remove the old cartridge, insert the new one, and screw the housing back together. The whole process takes less than a minute.
Yes. We offer a subscription service that delivers a fresh cartridge to your door every 6 months. Subscribers save on each cartridge and never have to worry about remembering to reorder.

Many customers report significant improvements in skin hydration and reduced irritation after using SYNONX. By removing chlorine and heavy metals that strip your skin's natural moisture barrier, filtered water allows your skin to retain its natural oils.
While SYNONX is not a medical device, removing chlorine and heavy metals from your shower water can reduce hair damage and breakage caused by these contaminants. Many customers report softer, stronger hair and less shedding after switching to filtered water.
Yes. Chlorine and hard water minerals are known triggers for eczema flare-ups and skin sensitivity. By removing these irritants, SYNONX can help create a gentler shower experience. However, we recommend consulting your dermatologist for medical advice.
The Vitamin C ceramic balls in Stage 3 release a small amount of Vitamin C (ascorbic acid) into the water, which helps neutralize chloramine and provides antioxidant benefits for your skin and hair. No other substances are added.
