Why It Matters

Mould doesn't wait for a complaint.

For Guests

Mould doesn't stay in one room. Left untreated in an A/C coil or a wall cavity, it spreads through the air your guests breathe — every night of their stay.

For Families

Children are more vulnerable to mould exposure than adults, with a higher risk of respiratory irritation and allergic reactions.

For the Planet

H Green is 100% biodegradable and non-toxic — real protection for guests and staff, without the environmental or safety trade-off.

For the Hotel

Non-corrosive and asset-safe, cuts energy and labour costs, and supports green-certification goals — eco-friendly by design.

The Full Solution Range

Four solutions. One protection system.

The A/C coil treatment is the core of the program, but mould does not stay in the plant room. Four solutions cover the full path — the A/C coil, the condensate tray, the room, and the wall. Each one shown here with its actual product label.

Foam Enzyme Cleaner

1L · ~15-min treatment

Coconut-derived multi-enzyme foam for hot A/C coils, HVAC, cold rooms, refrigeration and ice machines — non-corrosive, biodegradable, no need to dismantle the unit.

Remediation Pastille

Fitted at every service

20 pastilles per box. Secured in the condensate tray with the clip or tie wire provided — keeps overflow out of guestrooms.

Start With One Floor

Measure it before and after.

A pilot block of guestroom FCUs, scheduled around occupancy, gives you the two numbers that settle this in your own building — airborne contamination and airflow at every fan speed. The floor trades the same night. No disruption, no case to take on faith.
