We get this question asked periodically so below, we offer a simple explanation What is ventilation? By definition, ventilation distribute fresh air to a room, or building and exhaust “bad” air out from your room or building. To the incoming air (supply air) there is different options to filter the air (as today in many cities the air outside is polluted) before it is entering your room or building. Air filtration captures air particles at the source through specialized filters, for deeper reading about filters click here…Eurovent Air Filters Guidebook Air filters are essential in ensuring a good indoor air quality, which evidently increases productivity levels, reduces health risks, and provides for a good level of comfort. Simply put, ventilation is there to provide a good IAQ (indoor air quality). Normally this is measured in CO2/VOC (Volatile Organic Compound) concentration, oxygen level, temperature, humidity, etc. within the building, or facility. There are several types of ventilation systems: natural, mechanical and hybrid or "mixed–mode", and all with different degrees of airflow. Air Purification Defined Air purification is the process of sanitizing the air by neutralizing airborne toxins (gases and off-gassing, bacteria, viral or fungal matter, toxic pathogens, etc.). Air purification uses a different method than an air filter (example air filters in ventilation) to purify the air of toxins. Instead of simply trapping airborne particles within the mechanism of a tangible filter, an air purifier emits something to kill, neutralize, transform or otherwise render airborne toxins harmless. There are various air purification systems available. Some are better at purifying than others, and some systems are safer to use than others. Conversely, a purifier detoxes the existing air, making it supplementary to a ventilation system—not substitutional. One main distinction between air purifier and ventilation is that air filtration doesn't bring in the needed fresh air (oxygen) to a building; ventilation does that. Regardless how efficient the purification system, homes need a fresh air supply. VentPro ventilation solutions do exactly this: they exhaust old air and bring in new fresh and clean air. We want to create an airflow between the outside and inside, using a variety of components and technologies to regulate it. Without ventilation, modern homes trap too much humidity and pollutants. This can contribute to mold and mildew growth over time. Of course, using both an air purifier and a ventilator will result in the highest quality air inside your home. Not only will the air be free from contaminants, but it will also be fresh and healthy. Contact VentPro we are here to help you out! ERV Ventilation Exhaust Passive Vent Ventilation
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. Check out Ventpro exhaust fans models here... 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.

PM 2.5 FLIMMER®FILTER HIGH PARTICLE SEPARATION FILTER. Unfortunately, the air that comes into our homes is not always “fresh”. Our homes are bombarded by traffic fumes, industrial emissions, impure air from neighbouring buildings, particles, pollen, bacteria and viruses. In many cases, the air needs to be filtered before it enters into the home’s ventilation system. A "live" test with Fresh PM 2.5 Flimmer filter was done in Beijing China and Japan in a high polluted area. The Fresh PM 2.5 Flimmer filter was installed in Fresh Wall Vent Inlet a passive inlet that take in air into your home.

The Flimmerfilter is the first three- dimensional filter where separation is performed along the length of the fibres as opposed to conventional filters which essentially function like strainers, filtering the air through a barrier material. The Flimmerfilter has a very high separation capacity and effectively tackles particle problems in most homes. The PM 2.5 Flimmer Filter is also tested by Swedish Environmental Research Institute The PM 2.5 Flimmerfilter is a mechanical filter with an electrical charge that attracts air particles to the filter’s fibre threads. The statically charged fibres take out all kinds of particles, regardless of whether their charge is positive, negative or neutral. The Flimmer fibres have an electrically charged doublelayer that is fitted just under the surface of the filter, creating a very strong adhesive force. And because filtration is performed along the length of the filter, there is no risk of it clogging up like most conventional bag or barrier filters do - not even in the most contaminated of outdoor environments. Its design also gives you superb operating durability, and up to 2 years between filter changes (the exact replacement interval depends on the outdoor environment) and a low, almost constant pressure fall for the duration of service life. The Flimmerfilter is also 100% environmentally adapted, inflammable and thanks to the static electricity the dust adhesion is so high that filter changing is a completely dust-free process.
