Frequently Asked Questions
Äureas Ring: Sizing & Fit
How do I find my ring size?
The most accurate method is to measure the inner diameter of a ring you already own. Alternatively, wrap a thin strip of paper around your finger, mark where it overlaps, and measure the length. Visit our Size Guide for a full chart. A free sizing kit also ships with every order.
What if my size isn't right when it arrives?
We offer free size exchanges within 30 days of delivery. Simply contact our team and we will ship the correct size at no charge. We include a sizing kit with every order to minimize this.
Which finger should I wear it on?
Most users wear the Äureas Ring on the index or middle finger of their non-dominant hand. The ring works on any finger: choose whichever is most comfortable. Avoid the thumb for best sensor contact.
Äureas Ring: Health Tracking
How accurate is the sleep tracking?
The Äureas Ring uses a combination of PPG heart rate, 3-axis accelerometer, and skin temperature to estimate sleep stages (light, deep, REM). Like every consumer wearable, these are estimates, not a clinical sleep study; they are most useful for spotting trends over time.
Does it track workouts automatically?
Yes. The Äureas Ring automatically detects and logs over 30 activity types including running, cycling, swimming, strength training, and yoga, without requiring you to manually start a session.
What is HRV and why does it matter?
Heart Rate Variability (HRV) is the variation in time between heartbeats. Higher HRV generally indicates better recovery, lower stress, and greater cardiovascular fitness. The Äureas Ring measures HRV continuously overnight and uses it to calculate your daily Readiness Score.
Äureas Ring: Subscription & App
Is the app really subscription-free?
Yes, completely. You pay CA$199 once and receive lifetime access to the full Äureas app, including all features, historical data, and future updates. There is no monthly fee, ever.
Does it work with Apple Health or Google Fit?
Yes. The Äureas app syncs bidirectionally with Apple Health (iOS) and Google Fit (Android). It also integrates with Strava, Garmin Connect, and other major fitness platforms.
Äureas Ring: Device & Durability
Can I wear it while swimming or diving?
Yes. The Äureas Ring is water resistant to 100 meters (10 ATM). You can wear it while swimming, showering, surfing, and snorkeling. It is not rated for scuba diving below 100m.
How long does the battery last?
Up to 8 days on a single charge with continuous tracking enabled. Charging from 20% to 80% takes approximately 20–30 minutes using the included magnetic charging dock.
Will it scratch or tarnish?
The Äureas Ring uses a Grade 5 titanium shell which is highly scratch-resistant. The inner band is a smooth resin. Under normal daily wear, the ring maintains its finish for years. Avoid prolonged contact with harsh chemicals.
Äureas Pure Flow: The Product
What does the Pure Flow filter remove?
Fifteen filtration stages work in sequence: activated carbon, calcium sulphite and vitamin C media reduce chlorine and chloramine, and a sediment layer catches particulates. A shower filter does not soften hard water, and we don't claim it does.
What does it do to my skin and hair?
Chlorine can dry out the skin's acid mantle: the thin protective film that helps keep moisture in. Many people with sensitive skin and hair prefer showering in water with less chlorine. Results vary, and the filter is not a treatment for any skin condition.
What is the difference between 10 and 15 stages?
Both filters reduce chlorine, chloramine and sediment. The 15-stage adds five exclusive layers: Vitamin C balls, Germanium balls, Maifan stones, double-strength KDF-55, and triple-strength calcium sulphite. The 10-stage is a meaningful upgrade for most households. The 15-stage is built for people with sensitive or reactive skin, or who treat their shower as part of a wellness routine.
Can I drink the filtered water?
No. The Pure Flow is designed for shower use only. The filtration is optimised for skin and hair contact, not for drinking water standards. For drinking water filtration, a dedicated under-sink or countertop system is recommended.
What is included in the Full Starter Kit?
The Full Starter Kit contains everything needed for a complete installation: filter housing, filter cartridge, universal shower fitting adapter, Teflon tape and rubber seal. If you already own the housing from a previous purchase, select the Replacement Cartridge option instead.
What does it cost over time?
One payment. The filter cartridge lasts approximately 4 to 6 months under daily use. Replacement cartridges are available at CA$20 to CA$25 each, roughly CA$50 to CA$60 per year. No subscription. No app. No connectivity required.
Äureas Pure Flow: Installation
How do I install it? Do I need a plumber?
No plumber needed. Installation takes under two minutes: (1) Unscrew your existing showerhead. (2) Wrap the arm threads with the included Teflon tape. (3) Screw the Pure Flow housing onto the arm. (4) Reattach your showerhead to the housing outlet. No tools required.
How do I know when to replace the cartridge?
The cartridge lasts 4 to 6 months under daily use. There is no electronic indicator. The most reliable signals are a noticeable drop in water pressure, a return of the chlorine smell, or a change in how your skin and hair feel after showering. We recommend replacing every 4 months if you shower daily, or every 6 months for lighter use.
Will it affect my water pressure?
A new cartridge has no meaningful effect on water pressure. As the cartridge approaches end of life (typically after 4 to 6 months), you may notice a gradual reduction in flow. This is a natural sign that the filter media is saturated and it is time for a replacement.
Äureas Pure Flow: Compatibility
Will it fit my shower?
The Pure Flow uses a standard 1/2-inch BSP thread, the most common shower arm fitting in North America, Europe, and Australia. It works with fixed wall-mounted showerheads, handheld showerheads, and apartments with older plumbing. It is not compatible with built-in thermostatic systems or showers with proprietary non-standard fittings. If your existing showerhead unscrews by hand, the Pure Flow will fit.
Does it work with low water pressure?
Yes. The Pure Flow is designed to work in apartments and buildings with lower water pressure. The filter housing does not restrict flow under normal conditions.
Äureas Pure Flow: After Purchase
What if it leaks after installation?
Minor leaks at the connection point are almost always resolved by ensuring the Teflon tape is wrapped tightly (3 to 4 turns) and all fittings are hand-tightened firmly. If a leak persists, contact our support team. All units are covered by a 1-year limited warranty.
What is your return policy?
We offer a 30-day return policy on all unopened starter kits. If you have installed the filter and are not satisfied after 30 days of use, contact our support team. We review these on a case-by-case basis and stand behind the product. Replacement cartridges are non-returnable once opened.
Where do you ship?
We currently ship across Canada and the United States. Standard shipping typically arrives within 5 to 8 business days. Expedited options are available at checkout. Orders over CA$60 qualify for free standard shipping.
Äureas Lumé Brush: Usage & Care
How often should I use the Lumé Brush?
For best results, use the Lumé Brush 2–3 times per week on clean, dry skin. Each session should last 3–5 minutes. Overuse can cause irritation. Start with once per week and gradually increase frequency as your skin adapts.
Is it safe for sensitive skin?
Yes. The Lumé Brush has a gentle silicone bristle setting specifically designed for sensitive skin. Start with the lowest intensity and frequency. If irritation occurs, reduce usage or discontinue. Consult a dermatologist if you have severe skin conditions.
How do I clean the brush head?
Rinse the silicone bristles under warm water after each use. Once per week, soak the brush head in warm soapy water for 5 minutes, then rinse thoroughly. Allow to air dry completely before recharging. Replace the brush head every 6–12 months.
Äureas Lumé Brush: Battery & Charging
How long does the battery last?
The Lumé Brush provides up to 14 days of use on a single charge (assuming 3 sessions per week). A full charge takes approximately 2 hours using the included USB-C charger.
Is it waterproof?
Yes. The Lumé Brush is fully waterproof (IPX7 rated) and can be used in the shower or bath. However, do not submerge it for extended periods or use it in saltwater.
