Air Pollution: The entire North India, especially Delhi-NCR, is facing severe air pollution. The situation is such that Delhiites are facing difficulty in breathing. In such a situation, air purifiers have become a topic of discussion. These air cleaning devices, which were once considered unnecessary luxury items, have now made a place in middle class homes and the sales of the companies making these devices have increased significantly.
What is air purifier?
An air purifier is a mechanical device that improves indoor air quality by capturing pollutants and allergy-causing harmful particles from the air in the room. This machine draws in air and passes it through a high-efficiency particulate air (HEPA) filter that can trap even the smallest particles. This machine recirculates the cleaned air outside. In this way the indoor air gets cleaned and keeps circulating.
What is the price?
The price of air purifier ranges from three thousand to 60 thousand depending on the capacity of the machine. These devices are being manufactured by big companies as well as local companies. All of them have Hepa filter installed. The machine should be chosen according to the size of your room. A small device will not be of any use in a large room.
For whom is it more beneficial?
Patients with pre-existing respiratory conditions, families with small children and senior citizens are most sensitive to air pollution and are often recommended air purifiers. The use of air purifiers is believed to soothe or prevent triggers of lung, chest or heart disease in patients. But doctors say that there is no guarantee that respiratory diseases will be cured by its use. If you have chronic obstructive pulmonary disease (COPD) or respiratory failure, bad air can be harmful and an air purifier may be recommended. Since healthy people are exposed to the same air outside and inside, air purifiers do not make much difference to them. But there is no harm in this either. The truth is that air purifiers are beneficial only when a person remains in his room continuously.
what is hepa filter
HEPA H13 standard filters are very effective at capturing 99.95 percent of small and ultra-small particles. By the way, some advanced devices also have ultraviolet filters that use electromagnetic radiation to capture bacteria, viruses and mold instead of destroying them. Pre-filters and activated carbon filters generally capture larger particles in smoke and are less effective at trapping finer particles.
HEPA filters are generally considered better for people with allergies or respiratory problems due to their superior filtering capabilities. However, they may need to be replaced frequently, which increases the cost. Air purifiers are most effective when they run throughout the day, and should make the least amount of noise.
Typically, air purifier filters should be replaced every nine to 12 months. But if used in a highly polluted area or operated continuously, the filter may need to be changed several times. Most air purifiers are designed to clean the air in a single room and just placing one machine in the middle of the house may not do the trick. However, the solution to pollution is not just an air purifier for anyone.
