Precautions and tips

In addition to the price, style and function, consider the following factors as well before buying a thermo ventilator:

1. Installation fee

The price of a thermo ventilator does not include standard installation service. For details of the installation fee schedule, please refer to: https://www.fortress.com.hk/en/installation

2. Power consumption

A thermo ventilator uses a large amount of power so do not overlook this fact. Generally, the power consumption of a thermo ventilator is over 1,100W, which is about 3 times higher than that of a dehumidifier. Check the wattage before purchase. The larger the number, the higher the power consumption.

3. Size

Thermo ventilators come in various sizes. For example, for window mount types, you should take note of floor height to see if it can be installed in the bathroom. Arrange for a consultation to make sure it can be installed before buying.

4. Noise level

The thermo ventilator comes with a built-in motor and fan, so there will be noise during operation. If you want to enjoy a quiet shower, check the dB noise level before purchase.　

5. Ventilation rate

This function takes away moisture and odor in the bathroom. However, the higher the ventilation rate does not mean that the air is fresher. Ventilation rate can be calculated as below:

Number of air changes per hour (5 times) x room area (m2) x room height (m) = ventilation rate cubic meters per hour (CMH)

6. Splash resistance

Although thermo ventilators have a splash resistance level of IPX4, it is limited to the outer shell so avoid getting splashes on it when showering.
