Eco-friendly shower filter

The Aquapro MK-808 shower purifier is a high-end solution designed to improve the quality of domestic water. Thanks to its multi-stage filtration technology (NSF-certified KDF-55, activated carbon, calcium sulfite, ceramic balls, and magnetic treatment), it effectively removes chlorine (up to 99%), heavy metals, bad odors, and other contaminants.
Result: softer skin, silkier hair, and an increased feeling of comfort in the shower.

Why filter bath and shower water ? ? During a shower or bath, the pores of our skin dilate, allowing chlorine, chloramines, chlorinated derivatives, and other substances to more easily penetrate the epidermis. We consume more chlorine by taking our daily shower and bath than by drinking tap water. Furthermore, during a shower, we inhale 10 to 100 times more chlorine and chemicals than from drinking water. In a bath, chemicals are absorbed 600 times more through the skin than by ingestion.
For the many people who do not have the opportunity to benefit from well water, Biovie offers a filter to be placed between the hose and the bath or shower faucet. This filter removes chlorine and chlorine derivatives, heavy metals, and pesticides present in the water. It provides you with more pleasant and, above all, healthier showers.

💧 It is composed of two high-quality filtering materials that work in synergy: KDF and coconut shell activated carbon.

• The compounds responsible for the tastes and odors of water
• Pesticides and pesticide by-products
• Trihalomethanes and other disinfection by-products
• Algal toxins
• Chlorinated hydrocarbons and other volatile organic compounds (VOCs)
• Endocrine disruptors and numerous xenobiotic micropollutants
• Medication residues and those from our everyday products (cleaning and hygiene products)

The filter is very easy to install and improves the condition of your hair and skin after a few days of use.

💧 Characteristics :

Water filtration is done in 4 steps.

* First step: initial filtration
This step removes all suspended solid substances such as rust, sand, and others from the water.

* Second step: KDF
It not only effectively removes heavy metals from water but also harmful substances for the skin. It filters microorganisms, thanks to KDF (bacteria, fungi, algae...).

* Third step: Activated charcoal
It absorbs disinfection products: chlorine, HTH, calcium hypochlorite, and other undesirable substances.

* Fourth step
It removes the activated charcoal pellets and maintains the freshness of the water.

💧Analysis of the MK-808 Aquapro filtration:

The MK-808 uses multi-stage filtration technology, combining different media to optimally treat shower water. Here is the breakdown and analysis:

1. KDF-55 (copper-zinc alloy, 50/50, NSF certified)
- Role: Greatly reduces free chlorine (by up to 95–99%). Eliminates certain dissolved heavy metals: lead, mercury, nickel, chromium. Limits bacterial proliferation inside the filter through a bacteriostatic effect (prevents microbial growth).
- Mechanism: Redox reaction between chlorine and copper-zinc alloy, transforming free chlorine (Cl₂) into non-irritating chloride ions (Cl⁻).
- Key advantage: Effective even at high temperatures (unlike some activated charcoals).
- Limitation: Does not remove resistant pathogenic microorganisms or dissolved organic substances.

2. Granular activated carbon (GAC)
- Role: Adsorption of volatile organic compounds (VOCs) responsible for undesirable odors and tastes. Reduction of pesticides, solvents, and chlorination by-products (trihalomethanes, THM).
- Key advantage: Significantly improves sensory comfort (smell, feel on the skin and hair).
- Limitation: Reduced efficiency at high temperatures (> 40 °C), which is why it is paired with KDF-55.

3. Calcium sulfite (CaSO₃)
- Role: Ultra-fast chlorine removal (almost instantaneous reaction). Particularly effective on hot water.
- Key advantage: Very thermally stable, maintains its effectiveness in hot showers (> 60 °C).
- Limitation: Primarily targets chlorine, with little effect on other contaminants.

4. Activated ceramic balls
- Role: Fine mechanical filtration (reduction of suspended particles). Antibacterial effect due to the incorporation of mineral elements (e.g., ionic silver). PH stabilization and slight remineralization.
- Key advantage: Long lifespan, low pressure drop.
- Limitation: Variable effectiveness depending on manufacturing quality.

5. Magnetic treatmentanisotropic ferrite magnet)
- Claimed role: Reduction of limestone adhesion by temporarily modifying the crystallization of calcium carbonate (transition from calcite to aragonite).
- Technical note: This action is physical and reversible, does not eliminate limescale but can reduce the scaling of showerheads.
- Effectiveness subject to scientific debate, works better on moderately hard water.

Synergy and overall efficiency
- Chlorine: Near-total elimination thanks to the combined action of KDF-55 + calcium sulfite + activated carbon.
- Heavy metals: Significant reduction (KDF-55).
- Particles: Retention by ceramic beads and internal sieve.
- Odors and organic compounds: Effective adsorption by activated carbon.
- Bacteria: Prevention of proliferation in the filter (KDF + ceramic).
- Limestone: Partial reduction of (magnetic) adhesion

Lifespan and maintenance
- Capacity: ≈ 45,000 liters (or ~6 months for normal domestic use).
- Replacement recommended every 6 months to maintain effectiveness on chlorine and prevent media saturation.
- Operates in hot water up to 80°C (which is rare for a shower filter).
