BingMag.com 4 key points you should know when buying an air purifier

The best way to improve indoor air quality is to remove polluting sources and create ventilation and fresh air inside the house. But when these methods are not possible due to living conditions, room air purifiers can be a great help to you. Of course, it should be emphasized that air purifiers are designed to filter the air in a single room and do not cover the entire home. While room air purifiers help reduce indoor pollution, they also have limitations, which we will mention below.

What can an air purifier do!

An air purifier works well at filtering dust, soot and allergenic pollens. In general, numerous studies on these products show that the presence of HEPA filters leads to a 50% or more reduction of airborne particles. Also, in a study in 2018 on 130 households in America, it was found that filtration using these products has led to a 30% reduction in coarse particles such as dust.

Meanwhile, the question that The question is, do such devices help cardiovascular health? Approximately 12 studies in Vancouver, British Columbia. Taipei, Taiwan and the state of Massachusetts show that an air purifier can improve cardiovascular health in people. Also, another study in this field has shown that purified air, in the least possible case, improved the symptoms of allergies. In this regard, it is interesting to note that in a 2018 study by the University of California, participants with asthma reported a 20 percent reduction in clinic visits with such a device in the room.

However, It should not be a general vote for such benefits, because the scientific and medical communities do not definitively associate the use of air purifiers with health issues. In fact, very few long-term studies have been conducted in this field, and in some cases, contradictory results have been obtained.

The air purifier is effective in preventing the spread of the corona virus despite the presence of infected droplets to transfer the virus. But in order to increase the efficiency of the device, it is necessary to use an air purifier in a room.

The issue of using this device to prevent the spread of the corona virus is also an important issue. In general, air purifiers with HEPA filters can capture droplets in which the virus is carried (droplets from coughing, talking, or breathing). But in order to increase productivity, it is necessary to use an air purifier in a room.

What an air purifier can't do Do?

Getting to know the types of air purifiers

BingMag.com 4 key points you should know when buying an air purifier

In the market of this category of products, there are several different technologies. Air purifiers use them to reduce indoor pollution in rooms. Of course, you should keep in mind that some of these models can be useful for you be while others are not!

1. Air purifiers with mechanical filters (Models With Mechanical Filters)

Generally, models of air purifiers that work with mechanical filters use fans that force air to pass through a dense network of fine fibers. . Meanwhile, filters with a very small mesh, called HEPA filters, have the ability to trap 99.97% of particles with a certain size of 0.3 micrometers in diameter (for example, soot and plant pollens). Also, HEPA filters can effectively trap and remove larger particles, including dust, pollen, and some spores while suspended in the air.

About the limitations of air purifiers with mechanical filters It can also be acknowledged that these products do not help to remove the gases in the air, and at the same time, their maintenance may be costly for you; Because mechanical filters must be replaced every 6 to 12 months. It should be noted that usually the price of filters starts from 200 thousand tomans and above!

2. Air purifiers with activated carbon filters (Models With Activated Carbon Filters)

Instead of trapping particles and performing the same function as mechanical filters, this type of filter uses activated carbon to absorb some pollutants from the air. . Also, the air purifier with an active carbon filter has the ability to deal with some gases, but it is not formaldehyde, ammonia or nitrogen oxide.

Since active carbon filters do not have the ability to absorb particles, many Many of these devices, in addition to the active carbon filter, use a pleated panel air filter to absorb particles. However, the activated carbon filter saturates faster than the pleated filter and needs to be replaced every three months. Meanwhile, pleated filters need to be replaced every 6 to 12 months. Activated carbon filters are usually priced from 100,000 tomans.

3. Ozone generators

Ozone generators, as their name suggests, are devices that make pollutants react with ozone by producing it; In this case, pollutants change chemically. Despite the widespread advertising of these systems (especially in Iran), such devices are dangerous for indoor air quality and are not recommended by experts.

Ozone generator manufacturers often claim These devices emit safe levels of ozone, but tests show that even with this set of products set to emit low levels of ozone, some models exceed the FDA's 0.05 ppb limit (for commercial use). (medical) are exceeded.

Ozone generators often do not produce safe levels of ozone and usually exceed 0.05 ppb even at the lowest level. Therefore, such devices affect the indoor air quality of the room and its use is not recommended by experts.

In addition, EPA studies have shown that the presence of ozone in the environment impairs lung function and increases Throat irritation, cough, chest pain and lung tissue inflammation. Also, exposure to ozone may not be suitable for patients with asthma, emphysema and bronchitis.

4. Electronic air purifiers (Electronic Air Purifiers)

Electronic air purifiers ionize the particles in the air, in this case a magnetic attraction is created in the plates on the device or nearby surfaces and the particles stick to them. In this regard, it is necessary to emphasize that experts do not recommend electronic air purifiers, because they can produce gas such as ozone.

5. Ultraviolet Germicidal Purifiers (UVGI)

Some manufacturers claim that such air purifiers kill airborne viruses, bacteria, and fungal spores using UV radiation. But at the same time, you should know that some bacteria or molds are resistant to ultraviolet rays. In fact, the UV light must be powerful enough and the exposure to it must be long enough (from several minutes to several hours). Therefore, the cleaning operation will not be done in a few seconds.

This certification is given by the Home Appliance Manufacturers Association to a range of products and aims to determine the Clean Air Delivery Rate (CADR) and room size. CADR is measured in cubic feet per minute and the information reflects the amount of clean air that the air purifier can produce at its highest speed setting. Interestingly, among all models, purifiers with HEPA filters often score the highest CADR.

Generally, a CADR above 240 scores excellent, followed by 240 to 180, then 179. to 120, and finally 119 to 60 is the last score. Also, any air purifier with a score below 60 gets a poor rating. It should be noted that there are different CADR ratings for absorbing cigarette smoke, dust and pollen; So if, for example, you live with a smoker or use a fireplace in winter, choose an air purifier with a high CADR for tobacco smoke.

3. Paying attention to the size of the room to choose an air purifier

If you choose an air purifier based on the AHAM certificate, you can be sure that the size of the room is also taken into account. Otherwise, you should pay attention to the scope and size of the room for each model when buying online or in person.

Besides attention With this characteristic, it is necessary to know that there are generally a series of tips to minimize the noise of the air purifier.
