However, the only element that needs to be considered when talking about air purifiers it is the system they use to fulfill their purpose.
Many devices “invent” fancy filtration systems imagined to remove most impurities in the air.
The truth is that you have to look for one with a real HEPA filteracronym for high efficiency particulate air filterdesigned to capture 99.97% of particles with a diameter of 0.3 microns.
Since they are the most purchased of all, it is worth focusing on their characteristics and how to choose the best on the market.d
2. The dimensions of the room in which it will be installed
First of all, before purchasing an air purifier you need to measure the dimensions of the room where it will be installed.
These devices are optimized to clean specific sized rooms, since their power is measured by the frequency with which they manage to exchange all the air in the environment in which they are found, a characteristic called Air Changes per Hour (ACH).
The higher the ACH, the more powerful the air purifier. An ACH of 4 means it can exchange all the room air four times in an hour, so it can clean the room air in just 15 minutes.
Based on this and the size of the environment, the necessary assessments will need to be made.

There are many rather silent solutions available on the market, with included power between 24 and 30 decibels.
