No stress. No risk.

Just try it and see how it feels in your shower.

If your setup is different, we include adapters that work with most non-standard configurations.

Inside the box, you’ll find:

• Radii showerhead with a pre-installed vitamin-infusion filter
  
• 1 additional replacement filter cartridge
  
• Teflon tape for a secure seal
  
• Quick-start installation guide
  
• 90-day satisfaction guarantee
  

Installation is simple:

Just unscrew your current showerhead by hand, wrap the threading with the included Teflon tape, and twist Radii on.

If it feels tight, use a cloth for grip.

Most people install it in under 5 minutes — no tools or plumber needed.

Whole-house systems are great, but they treat the water at the entry point of your home — not at the shower. Water can pick up impurities again as it travels through pipes and fixtures.

Radii adds an additional, final stage of filtration right before the water touches your skin and hair.

And unlike whole-house filters, Radii includes a vitamin-infusion capsule with A, C & E — a feature designed specifically to enhance the shower experience.

Many people with whole-house filters still choose Radii because:

• It filters water at the point of use (the shower itself)
  
• It adds a vitamin-infusion experience that whole-house systems don’t offer
  
• It helps the water feel softer and more refreshing on skin and hair
  

Whole-house filters clean the water.

Radii enhances the feel of the water on your skin and hair.

Absolutely — Radii is apartment-friendly.

Installation is tool-free and requires no permanent changes. Just unscrew your current shower head and twist Radii on in its place.

When you move, simply remove it and reinstall your original shower head.

It’s quick, reversible, and landlord-safe.

Yes — Radii fits standard shower setups.

Radii installs in minutes with no tools required. Just unscrew your current shower head and twist Radii on.

It works with both fixed and handheld shower configurations.

If you have a non-standard connection, our support team can help guide you to a solution.

Filter life depends on your water quality and usage.

Most customers replace their cartridge every 2–3 months. If your water has more minerals or chlorine, you may choose to replace it a little sooner.

You’ll know it’s time to swap the cartridge when:

• 
  Water pressure feels lower than usual
  
• 
  The flow doesn’t feel as smooth or refreshing
  

Replacement cartridges are $29.95 each.

They’re available individually or in discounted multipacks on our website.

It’s a small ongoing maintenance step to keep your shower feeling clean and refreshed.

No indicator needed — it’s easy to tell.

You’ll know it’s time to replace the filter when:

• 
  Water pressure feels lower than usual
  
• 
  The flow doesn’t feel as smooth or consistent
  
• 
  It’s been a few months of regular use
  

After the first replacement, most people naturally get a sense of their own timing based on their water and shower habits.

Radii is designed to help reduce impurities in shower water.

Its multi-stage filtration system includes materials such as KDF, activated carbon, and sediment screens — each stage focusing on different types of impurities.

While whole-house systems treat water as it enters the home, Radii filters again at the shower, right before the water touches your skin and hair. It also includes a vitamin-infusion capsule with A, C & E for a refreshing shower experience.

Customers choose Radii because it:

• 
  Helps reduce chlorine and other common water impurities
  
• 
  Includes multi-stage filtration for different impurity types
  
• 
  Adds a vitamin-infusion experience that typical filters don’t offer
  

Radii doesn’t just filter water —

it elevates the way your shower feels.

Absolutely. Radii works with any shampoo, conditioner, or skincare routine.

Filtered water helps soaps and shampoos lather more easily and rinse cleanly, and conditioners and moisturizers feel like they absorb instead of leaving a film behind. Many customers notice they use less product because their water isn’t working against them.

Here’s what makes Radii different:

Most shower filters only subtract — they remove chlorine and chemicals, but leave your skin with nothing extra. Radii doesn’t stop at filtration. It transforms your shower into a skincare step.

As we get older, our skin naturally produces fewer skin-supporting elements like ceramides, collagen, and moisture-retaining lipids. Simply removing harsh chemicals isn’t always enough — the skin benefits from being nourished during the process.

Radii infuses your water with vitamins A, C, and E — three ingredients commonly found in high-end skincare:

• 
  Vitamin C – supports skin brightness and helps neutralize chlorine on contact.
  
• 
  Vitamin E – provides antioxidant protection against environmental stressors.
  
• 
  Vitamin A – encourages renewal and keeps skin looking smooth and healthy.
  

Instead of just filtering water, Radii actively enhances it.

It’s like stepping into a shower that doubles as a skincare treatment — every day.

Hard water is one of the toughest challenges for any filter — but Radii’s 15-stage system is engineered for it. Several stages in our system specifically target minerals found in hard water (like calcium, magnesium, and iron), helping prevent buildup and clogs.

In hard-water regions, expect a filter life of about 4–6 months instead of 6–8.

Many customers with iron-heavy well water say Radii is the first filter that keeps working without turning their shower orange or clogging after a few weeks.

To extend filter life, you can easily remove and rinse the cartridge — quick instructions are included.

Radii doesn’t just survive hard water.

It’s built for it.

Absolutely. Radii is designed to work for all ages, skin types, and hair textures, regardless of your water quality. Whether your concern is dryness, sensitivity, scalp irritation, or just wanting your hair to feel smoother and your skin to feel softer, Radii supports a healthier shower experience.

People use it in:

• apartments and dorms
  
• older homes with aging pipes
  
• new builds with high chlorine or hard water
  

And because our system adds back vitamins A, C & E after filtration, you’re not just removing harsh chemicals — you’re upgrading the experience.

Try it risk-free. Radii comes with a 60-day money-back guarantee.

If you don’t notice a visible difference in how your skin and hair feel, send it back. No hassle, no stress.

You have nothing to lose — except the chemicals in your water.

Yes — Radii actually increases the feeling of water pressure.

It sounds counterintuitive (filters usually reduce flow), but here’s why Radii is different:

• Precision-engineered micro-nozzles compress the water stream into a more focused spray, which makes the water feel stronger and more energizing.
  
• The filtration stages reduce internal buildup, which can improve flow compared to old, clogged showerheads.
  
• Many people with naturally low pressure are surprised at how much better their shower feels after switching.
  

Customers say things like “I didn’t even know my water pressure could feel like this.”

And if you have a tankless water heater that sometimes shuts off due to low flow, Radii’s design can help maintain consistent pressure so the heater stays engaged.

Result: a cleaner, more refreshing, higher-pressure shower — without using more water.
