According to institute like World Health Organization (WHO) the air indoors is worse than outdoors!

This days in urban cites like Bangkok the PM 2.5 (Particle Matter) have periodic time a high unhealthy level of PM 2.5. This air we don’t want to take in to our home and if we have closed windows and no fresh air coming into our homes the indoor air will quick be unhealthy. Air pollution levels remain dangerously high in many parts of the world. New data from WHO shows that 9 out of 10 people breathe air containing high levels of pollutants.

So, what can you do to make your indoor air healthier and better?

One good way is to create ventilation in your home, ventilation means that you create an air flow in your home and change the air inside. A good rule is to change it 1 time every 2ndhour (0.5 air change per hour).

How can you do that?

In this article I will take up 2 ways to do it but if you are interested to know more you can read this article https://ventpro.co.th/whole-house-mechanical-ventilation/

The air we take in from outside needs to be filtrated so for example we don’t take in the polluted air with PM 2.5.

One way to do that is to use Passive Wall Vents (make up air inlets) that have a PM 2.5 filter. The passive wall vents with PM2.5 flimmer filter you install in your bedrooms, living room and common area. Normally it is one in bedroom area as one passive wall vent with PM 2.5 flimmer filter can take in air for 15-20 m2 so in bigger rooms like your living room you need to install more.

To this you need an exhaust fan that you install usually in bathrooms. The exhaust fan operates either continuously or intermittently to exhaust stale air and moisture generated in those rooms. This strategy creates a modest negative pressure in your home, and that pulls in fresh air from the passive wall vents. An advantage of this strategy is simplicity and low cost.

TH means it have sensor for humidity (H) and timer (T). When humidity rise example when you take a shower the fan starts automatic and will not turn off until the humidity level is down to your settings. Timer enables the fan operation within 2-30 minutes after the exhaust fan is switch off.

Have a continuous operation at low speed and low energy, when ex humidity rise it goes up to full speed. This to exhaust the humid air as quick as possible and then down to load speed again.

Balanced ventilation with energy recovery

A balanced ventilation system has two fans: one bringing outside air into the building, and the other exhausting stale interior air. It filters both air streams, example incoming air is filtered with a G4 and a F7 filter and exhausting air with an G4 filter. This prevent example PM2.5 entering your home. You get fresh and clean air in your home.

In balanced ERV ventilation systems, heat and moisture are exchanged between the two airstreams (the two air streams don’t mix), reducing the heating and cooling loads caused by outside ventilation air.

ERV deliver fresh air through duct pipes to spaces that are most lived in (living room, bedrooms, etc.) and exhaust indoor air from places where moisture or pollutants are generated (bathrooms, kitchen, laundry room).

This is a great way to ventilate a home. It’s also more expensive than the ones above but you get a controlled airflow for your home.

If budgets allow, going with balanced ventilation is recommended.
