Results vary by person and water type, but here's what most Filtera customers experience:

• Weeks 1–2: Skin feels softer and less tight after showering. Some notice reduced redness or irritation.
• Weeks 3–4: Hair texture improves — less breakage, more shine, better product absorption.
• Month 2+: Scalp conditions calm, hair color lasts longer, and skin stays hydrated for longer periods after each shower.

Nothing is wrong — this is completely normal and one of the most common things new customers message us about.

Your skin and hair have been exposed to unfiltered water for years. Rebuilding a healthy moisture barrier and repairing mineral-coated hair takes consistent exposure to clean water over time. One shower won't undo years of damage.

What you will likely notice first is a subtle difference in how your skin feels after stepping out — less tight, a little softer. That's the clearest early signal Filtera is working. Trust the process and give it the full 60 days.

Yes — and this is one of the most dramatic results our customers report. Chlorine is a bleaching agent that attacks hair color with every shower. Hard water minerals coat the hair shaft and prevent color molecules from bonding evenly, causing fast fading and uneven tone.

By removing both chlorine and hard minerals, Filtera helps your hair color last significantly longer between salon visits. Many customers report going 2–4 additional weeks before needing a touch-up.

Chlorine is a known trigger for eczema and skin inflammation. It disrupts your skin's microbiome — the community of beneficial bacteria on your skin's surface — and strips the natural oils your skin barrier depends on to stay intact.

Removing chlorine from your shower water is clinically recognized as one of the most impactful environmental changes for people with eczema-prone skin. Filtera's 20-stage filtration removes chlorine, chloramines, heavy metals, and sediment — all of which can aggravate sensitive skin.

Each "stage" refers to a distinct layer of filtration media that targets a different type of contaminant as water passes through. Filtera's 20 stages cover the full spectrum of common shower water threats:

• Stages 1–5: Stainless mesh + PP cotton removes sediment, rust, sand, and algae
• Stage 6–10: KDF-55 removes 99.98% of chlorine and heavy metal ions
• Stages 11–15: Activated carbon inhibits bacteria and removes odors
• Stages 16–19: Ion exchange resin softens hard water minerals
• Stage 20: VC Ball infuses the water with Vitamin C

Most competitor filters handle 1–3 of these threats. Filtera addresses all of them in a single pass.

The VC Ball is Filtera's final filtration stage — and it's the one that sets us apart from every other shower filter on the market. Instead of just removing harmful things from your water, the VC Ball actively adds something beneficial back.

As water passes through the VC Ball ceramic media, it gets infused with Vitamin C — a clinically studied antioxidant that neutralizes any remaining trace chlorine, protects skin from oxidative damage, supports collagen production, and strengthens the keratin proteins in your hair.

Most filters stop at removal. Filtera removes and restores.

The Filtera cartridge is rated for up to 8 months based on average daily use (one shower per person per day). If your household showers more frequently, has multiple users, or your water has an especially high concentration of contaminants, it may need replacing closer to the 5–6 month mark.

We'll send you a reminder email before it's time to replace — so you never have to track it yourself or wake up one day showering through an expired filter.

Filtera is designed with a high-flow architecture that maintains strong water pressure through all 20 filtration stages. The vast majority of customers notice no meaningful difference in pressure.

If you already have unusually low water pressure in your home (due to old pipes, building infrastructure, or water supply issues), you may notice a slight reduction — but this is not specific to Filtera and would apply to any shower head filter.

Filtera's housing is constructed from ABS with stainless steel internals. The matte black finish is UV-resistant and scratch-resistant — it won't peel, chip, or discolor with regular shower use.

We designed Filtera to look as good as it performs. The matte black finish is built to match modern bathroom fixtures and hold up for years of daily use.

Yes. Filtera holds three internationally recognized certifications:

• ISO 9001 — quality management certification confirming every unit is manufactured to a consistent, controlled standard
• ISO 14001 — environmental management certification confirming responsible, sustainable manufacturing practices
• CEC Certified — compliance certification for water filtration fixtures

Most shower filter brands don't disclose certifications at all. We're proud of ours.

No plumber needed. Filtera installs in under 5 minutes with zero tools required.

• Unscrew your existing shower head from the shower arm
• Wrap the shower arm thread with the included plumber's tape
• Hand-tighten Filtera onto the arm until snug
• Turn on your water and check for leaks

If you were able to install your last shower head, you can install Filtera.

Filtera uses a standard G1/2 thread — which is the universal standard for shower arms across the US, UK, Canada, and Australia. This means it fits virtually all standard shower arms in residential homes and apartments.

If you have a non-standard or custom shower system (some luxury or commercial fixtures have proprietary connections), we recommend checking your shower arm thread size before purchasing. If you're unsure, email us and we'll help.

A small leak almost always means the plumber's tape wasn't wrapped tightly enough, or Filtera needs to be tightened a little more.

• Turn off your water supply
• Unscrew Filtera and re-wrap the shower arm with 3–4 layers of plumber's tape
• Hand-tighten Filtera back on — firm but not forced
• Turn the water back on and check again

If you're still experiencing a leak after this, email us at support@filtera.com and we'll help troubleshoot or replace the unit.

Hard water is extremely common — over 85% of US homes have it. The most common signs include:

• White chalky buildup around your shower fixtures or faucets
• Soap that doesn't lather well and leaves a filmy residue
• Hair that feels rough or coated even after conditioning
• Skin that feels dry or tight after showering despite moisturizing
• Water spots on glass shower doors that won't wipe clean

If you're seeing any of these, hard water is almost certainly a factor in your skin and hair health.

Filtera is designed and optimized for standard municipal (city) water supplies. Well water can contain higher concentrations of minerals, iron, sulfur, and biological contaminants than city water — and the specific composition varies significantly by location.

Filtera will still filter common contaminants from well water, but if your well water has particularly high iron or sulfur content, a dedicated whole-house well water filtration system may serve you better as a primary solution.

No — Filtera is specifically designed for shower use and is not intended or certified for drinking water filtration. Drinking water filtration requires a different set of standards and certifications.

For drinking water, we recommend a dedicated under-sink or countertop drinking water filter.

We'll send you an email reminder before the 8-month mark so you never have to think about it. Signs that your cartridge may be past its peak include:

• A slight chlorine smell returning to your shower water
• Your skin or hair starting to feel more like it did before Filtera
• Slightly reduced water flow (filter media becoming saturated)

Replacement cartridges are available on our website and take under 2 minutes to swap.
