What is an Air Filtration system?

Air Filtration systems also called Air Purifiers are basically devices used to filter the air. The dust, debris, smoke, odour, pet dander, moulds and other air pollutants make the indoor air unhealthy to breathe. By using Air Filtration Units, these pollutants can be trapped in the filters of the system and the circulation of fresh and healthy Indoor Air is made possible.

How does Air Filtration System Work?

The Air Filtration systems of Air Purifiers are of different types. Some are used in combination with the home Furnace while others work independently. In both cases, the working principle is almost the same. The system sucks the Air in the room and passes it through its filters that are mainly HEPA (High-Efficiency Particulate Air) filters. The HEPA filters have an amazing tendency to trap almost 99% of air contaminants of size greater than 0.3 microns. The purified air then comes out of the system and circulate in the room. The process continues and the Air continues to get filtered.

Advantages of Air Filtration Systems/Air Purifiers:
In this time of every increasing pollution, Air Purifiers are no less than a blessing for the provision of purified Air. Below are some advantages of the Air Purifiers:

Ultimate Filtration:
The filtration efficiency of a filtration unit varies model to model, however, a high -efficiency, quality unit can remove 99.9% of impurities of size 0.3 microns and bigger. This drastically purifies the Air and makes it healthier to breathe eradicating the possibilities of diseases.

Treats Asthma:
Some Air Purifiers are designed keeping in mind the special needs of people suffering from sinus, asthma and other allergies. Such models are particularly useful in homes where there are patients with the mentioned health issues.

Sucks Smoke:
While you inhale the smoke, there are some Air Purifiers that are designed for smokers so that the consequences of indoor smoking may easily be combated. These devices remove the smoke from the air so that it does not contaminate the air for other members of the home.

Prevents Odour Preserve Decor:
Some Air Filtration units also help combat room odours like smoke, cooking, and others. Moreover, the Air Purifiers are also helpful in keeping the home decor since they trap the particles that contribute to the damage of furniture, wallpapers and other equipment.

Disadvantages of Air Filtration Units:
Every home comfort appliance if has its pros has its cons too and Air purifiers are no exception. They too have some disadvantages, however, these disadvantages can be countered using safety strategies and doing proper maintenance:

Ozone Emission:
Ozone is harmful! The most hazardous effect of Air Purifiers is that they begin to emit ozone if not well maintained. This gas is severely harmful, particularly for elderly and children. Consequently, instead of purifying air, they begin to impurify it worsening the indoor air quality.

Non-efficient for combating gases:
It has been proven that the Air Purifiers have so far not been very efficient with combating gases and odours. Some products may claim to do so, but the filtration an Air Purifier mainly does is of dust, debris, pet dander, and other such clear particles.

Can't trap small particles:
As mentioned above, the best an air purifier can do is to trap particle of 0.3 microns and greater. Particles below this size do not get trapped and thus remain in the Air that we breathe.

Bottom Line:
Everything has its pros and cons. The best way is to go natural and grow plants inside the home to filter Air. However, in case you choose to use Air Purifiers, make sure the pros do not turn into cons. For that, purchase quality products and take services from a reliable HVAC service provider.
