Ultimate Formaldehyde Killer | Air Purification Series

International Patent (Japan, Europe, USA) | Made in Japan | Professional Formaldehyde Removal, Odor Elimination, Indoor Air Purification


Not just masking odors, but decomposing and eliminating them from the source

Most deodorizing products and air fresheners on the market only mask odors with fragrance, failing to truly solve indoor air pollution problems. This product uses graft polymerization patent technology, which thoroughly decomposes formaldehyde, VOCs, and odor substances into harmless substances through chemical neutralization reactions, and also has  99.9% antibacterial properties. It is the most effective solution for formaldehyde removal in newly renovated spaces, eliminating smoke odor, and pet deodorization.

Tested by an independent laboratory in Hong Kong: Over 95% formaldehyde removed in approximately 90 minutes
Certified by Yokohama National University, Japan: Safe and non-toxic, harmless to humans and pets

Decomposition Principle (Chemical Reaction)

Aldehyde (Formaldehyde) Decomposition:

  • Formaldehyde: R-NH2+HCHOR-NCH2+H2O

  • Acetaldehyde: R-NH2+CH3CHOR-NCHCH3+H2O

Odor Substance Decomposition:

  • Ammonia (urine odor/body odor): R-SO3H+NH3R-SO3NH4

  • Acetic acid (pungent sour odor): R-NH2+CH3COOHR-NHCOCH3+H2O

Product Ingredients: Graft copolymer, silver ions, water, preservatives


Boxed Gel | Instructions for Use

Key Usage Conditions (directly affect formaldehyde removal and odor elimination effectiveness):

  • Must be placed in a sealed environment with air circulation (e.g., air conditioning on, fan on with door closed)

  • The product must be placed in a breezy location to aid evaporation, allowing active ingredients to fully contact indoor air.

If none of the above conditions can be met, the deodorizing and formaldehyde removal effects will be significantly reduced. It is recommended to choose the spray version instead.

Usage Steps:

  • Severe odor or high formaldehyde concentration: Remove the protective pad and lid, then place directly (faster consumption, stronger removal effect).

  • Slight odor or for daily indoor air maintenance: Remove the protective pad, then twist the lid back on (slower consumption).

The appearance of white crystals during use is normal. The product shrinking into a small hard lump indicates it has been used up.


Spray Version | Instructions for Use

Method One (Recommended: Use with a fogging gun for more even coverage)

Formaldehyde removal from painted / wallpapered surfaces:

  1. Perform in a well-ventilated environment; opening windows is recommended.

  2. Clean the surface with a dry cloth to remove dust.

  3. From a distance of about 30cm, lightly sweep the surface with the fogging gun on, then let it air dry.

Formaldehyde removal and deodorization for wardrobe / shoe cabinet / storage cabinet surfaces:

  1. Perform in a well-ventilated environment.

  2. Clean the surface with a dry cloth.

  3. Spray from about 30cm away, then wipe the surface with a slightly damp cloth, and let it air dry.

Method Two (Without using a fogging gun)

Paint / Wallpaper: Spray 1-2 times from about 30cm away until slightly damp, then let it air dry.

Wardrobe / Shoe Cabinet: Spray the mist onto a cloth until damp, then wipe the surface, and let it air dry.

Clothes with smoke odor: Spray evenly over the entire garment; no washing required.

Key points for use:

  • Spray over as large an area as possible; avoid excessive accumulation in one spot.

  • After spraying for formaldehyde removal, it is recommended to open all cabinet doors and windows for ventilation for over 48 hours to accelerate formaldehyde dissipation from indoors.

  • After cleaning with a detergent, respray to replenish.

  • In humid environments (high humidity seasons in Hong Kong), a sticky sensation may occur. It is recommended to use a dehumidifier or fan to speed up drying.

  • The product has passed safety tests for import and skin contact in Japan. There is no need to worry if you accidentally come into contact with undried spray.
