HAPI makes replacement very clear and visible.

Over time, the internal filtration media will change colour as it captures chlorine, rust, and impurities from your water. This colour change is intentional and designed to help you understand when the filter has done its job.

We recommend:

• Taking a photo of your HAPI filter before first use
• Checking the filter again after 1.5 months, or earlier
• Comparing the colour to your original photo

When the filter becomes noticeably darker, this indicates it has absorbed a high level of impurities and should be replaced to maintain optimal performance.

The colour change occurs as the filter actively captures:

• Chlorine and chloramines
• Rust and pipe sediment
• Impurities from hard or polluted water

This visual transformation allows you to see the filtration process in action — something most shower filters do not offer.

On average, HAPI should be replaced every 2–3 months.

However, replacement timing depends on:

• How often you shower
• The area you live in
• Local chlorine levels
• Water pollution and pipe condition

In areas with higher chlorine or older infrastructure, you may notice the colour change sooner.

Yes — and we encourage it.

Checking your filter after 4–6 weeks helps you understand:

• Your local water quality
• How hard your water is
• How much chlorine your shower water contains

This makes HAPI both educational and functional.

Yes — this is one of HAPI’s key advantages.

Many shower filters on the market are tested primarily in cold water, where filtration is easier. HAPI was specifically tested and designed to function effectively in both cold and hot water, including typical shower temperatures.

This is critical because:

• Hot water releases more chlorine vapour
• Filtration performance often drops at higher temperatures
• Showers are almost always taken with hot water

HAPI is engineered to perform where it matters most — in real shower conditions.

When water heats up:

• Chlorine becomes more volatile
• More chlorine is released into the air and steam
• Skin and lungs are more exposed during showers

HAPI’s multi-stage system — especially Calcium Sulfite and Vitamin C — is designed to remain effective under heat, ensuring consistent performance.

Yes. HAPI uses two complementary stages to address chlorine:

• Calcium Sulfite Stones for rapid chlorine reduction
• Vitamin C (42,000 mg) to chemically neutralise chlorine and chloramines

Together, they help make shower water gentler, fresher, and more comfortable.

HAPI helps reduce the harsh effects of hard water, which can:

• Dry out skin
• Leave hair feeling dull or coated
• Cause scalp discomfort

Many users notice a clear improvement in how their skin and hair feel after showering.

HAPI supports skin and scalp comfort by:

• Reducing chlorine and impurities
• Supporting moisture balance
• Introducing Vitamin C and skin-supportive ingredients

Many users report:

• Softer-feeling skin
• Less dryness or tightness
• Improved scalp comfort
• More manageable hair

Yes. Vitamin C (ascorbic acid) is well known for its ability to neutralise chlorine, especially in warm water environments.

In HAPI, Vitamin C:

• Helps reduce chlorine exposure
• Supports skin barrier function
• Contributes to scalp comfort and hydration

Snail essence is widely used in skincare for its ability to support skin hydration, comfort, and surface smoothness.

In HAPI, it helps support:

• Moisture retention on the skin
• Improved skin smoothness and softness
• Reduced feeling of dryness after showering
• A more comfortable and soothing shower experience

Snail essence works by supporting the skin’s natural moisture balance, helping the skin feel calmer and more conditioned during and after water exposure.

HAPI uses gentle essential-oil-based aromatics designed to enhance relaxation without overwhelming the senses.

The aroma is subtle and suitable for daily use.

Yes — as the filter works and absorbs impurities, the aromatic layer gradually softens. This is normal and part of the filtration process.

No. HAPI is designed to maintain comfortable water flow without noticeable pressure loss.

Yes. HAPI installs in minutes:

• No tools required
• Fits most standard shower connections
• An extra rubber seal is provided to help prevent leakage if required

Yes. HAPI is compact, portable, and designed for global compatibility, making it ideal for:

• Home use
• Hotels
• Travel

Yes. HAPI is designed for daily shower use and suitable for adults and children.

No — the colour change is a feature, not a flaw. It is visual proof that HAPI is actively filtering your shower water.

Water quality varies greatly depending on:

• Country
• City
• Plumbing infrastructure
• Chlorine treatment levels

Faster colour change simply means your filter is working harder.
