IMPORTANCE OF INDOOR AIR QUALITY
Buildings nowadays mostly are tightly built with aluminum casing windows and rubber lining door to retain energy efficiency and limit heating or cooling loss. However, it comes at the cost of poor indoor air quality. In order to provide a healthy living environment to you, ventilation plays an essential role.
WHY INDOOR AIR QUALITY IS IMPORTANT?
You can't see it, but you take a lot into your body - AIR
Air quality in a house is an important factor for your health and comfort. In general, windows are not opened in airtight house due to using of air conditioning.
It is difficult to fulfill air exchange in a modern house, as a result, the stale indoor air becomes polluted easily.

Besides "Sick House Syndrome", insufficient ventilation also affects human's health and aging of building
.Yellow stain on wall caused by tobacco smoking
.Allergic illnesses induced with mold and mite that are caused by moisture
·Discomfort due to smells from toilet and cooking
.Lowering of concentration due to shortage of oxygen
·Building deterioration resulting from condensation and mold
AIR PROBLEMS IN HOME
Home Airtightness
Homes designed and built in recent years are more airtight and energy efficient than in the past. To obtain an airtight design, house wraps, newly designed windows and doors, sealing caulks and other insulating materials are used to create a seal for optimum energy efficiency. It results the cost saving to heat and air-condition at home, but pollutants retained in airtight buildings can be hazardous to our health and can jeopardize structural integrity.

Issues Raised with Home Airtightness?
Highly airtight house restricts air ingress from outside that can closely retain the expected indoor temperature for energy saving. However, airtightness also brings out the problem of indoor air quality (IAQ) which may be a cause of sick house syndrome.

Bypass Ventilation for Speedy Exhaust of Polluted Air
Diversion damper is equipped for Bypass Ventilation. Return (room) airflow (RA) is greater than supply airflow (SA) allowing speedy exhaust of indoor polluted air.
By using bypass ventilation during season change, it will be more comfortable and energy saving.
