Air Purifier Price BD

Living in houses tends to generate more dust and it is normal. If it bothers you, we recommend placing an air purifier in the areas of the house with more activity. The air purifier helps combat the discomfort caused by allergies to pet hair, dust, smoke, odors, mites and bacteria.

Your home environment can be fully controlled. Turn it into an oasis for your lungs. For this reason, we must pay attention to a series of aspects that will give us the key to finding air purifier price in Bangladesh that best suit our needs.

How Does An Air Purifier Work?

The mission of an air purifier is to eliminate elements present in the air: pollen, mites, dust, tobacco smoke… in general, pollutants. As a consequence, it returns cleaner air and in some cases, fewer odors, since they trap the particles responsible for it.

To retain these particles, they first capture the air from the environment using a fan and, after passing through a filtering system where impurities are trapped, the air returns to the room.

Although there are several technologies to purify the air, such as electrostatic precipitators or the use of ozone, as we have previously mentioned, the one used commercially is high-efficiency filters.

Factors to Consider When Choosing An Air Purifier in Bangladesh

HEPA Filter

The retention capacity of the filter that integrates the air purifier is essential because it determines the quality of the air that will be released into the room. In this sense, the recommendation is to look for models that have HEPA (High-Efficiency Particulate Air ) filters and not “HEPA type”.

Why this tint? For a filter to be called HEPA, it must meet certain standards, that is, it must trap all particles equal to or greater than 0.3 microns in diameter with 99.97% effectiveness.

How big is the room to purify?

The next aspect to assess is knowing the cubic meters of the room whose air we are going to purify. And it is that as happens with air conditioners, it is not the same to operate in a room of 10 square meters as to condition a room of 50 cubic meters.

To dimension the room we will simply calculate its volume. That is its surface multiplied by the height. Air purifiers offer this information in their specifications or an approximation of the surface to be purified.

It is important to know this information to be able to size our purification needs so that we do not fall short or invest more than necessary in an oversized purifier.


Hand in hand with the purification needs is the necessary power to carry it out in the time detailed in the specifications. In general, the more cubic meters we have to cover, the more power we will require. This power is usually given as a function of the airflow rate purified per unit of time.

In case of not having enough power, the air purifier would be forced to operate for a longer time, something that in the long run would affect both the performance of the device, its useful life and electricity consumption.


It’s easy to overlook the noise section when choosing an air purifier, a mistake we’ll pay for as soon as we get it out of the box and into operation.

Although it is true that due to its dimensions it is a portable device, we must bear in mind that the air purifier will be operating in our home continuously, in our presence and sometimes when we are sleeping or doing activities that require silence.
