If you want to buy Air Purifier to get rid of poisonous air, then take special care of these things, otherwise any damage may happen.

Tech News Desk – Pollution levels in Delhi-NCR become a matter of serious concern every year during the winter season. This time too, even before the onset of winter, the level of pollution in the air has become very dangerous, which can be extremely harmful for your health. Today AQI crossed 300 in some areas and is expected to reach 400 after Diwali. Crossing 400 of AQI means that the amount of fine particles (PM2.5 and PM10) in the air becomes so high that they can directly enter our lungs and blood.

Due to this, even a healthy person can have many problems like difficulty in breathing, sore throat and cough, burning sensation and watering of eyes. People who have asthma or any respiratory disease, their condition may worsen. You can protect yourself to some extent by taking measures like a healthy diet, keeping windows and doors closed, always staying hydrated. Apart from this, you will also have to take measures to protect yourself from polluted air inside the house. For this you can use high quality air purifier. Make sure to install air purifier in bedroom and living room. HEPA Filter: Make sure the air purifier has a HEPA (High Efficiency Particulate Air) filter. It can filter up to 99.97% of small particles (up to 0.3 microns), which is effective in fighting pollution, dust, smoke and allergen particles in the air.

CADR (Clean Air Delivery Rate): CADR shows how quickly and how much air the purifier can clean. Prefer purifiers with higher CADR ratings, especially if you are buying for a larger room.

Coverage Area: When buying a purifier, choose according to the size of the room you are in. It's important to check the coverage area listed in the product description to make sure it's right for your room.

carbon filter: If you want to avoid smoke, odor or harmful gases in the house, choose a purifier with an active carbon filter. It can also effectively remove odors and gaseous pollutants.

Air Changes Per Hour (ACH): It measures how many times the purifier can purify the air in a room in an hour. In highly polluted areas like Delhi, you need a purifier with at least 4-5 ACH.

noise level: The noise level of the purifier should be low, especially if you want to use it at night or while sleeping. To check this, check the noise rating of the product. 35-50 dB is ideal.

It would be better if these were smart features.
Smart Sensor: Some purifiers come with smart sensors, which adjust the speed of the purifier by monitoring the air quality. This is a great feature as it helps in saving power and continuously monitoring the air quality.

Alarm and PM2.5 Indicator: A good air purifier can monitor PM2.5 particles, which are the most harmful particles of pollution. Some purifiers also have a real-time air quality indicator, which shows you the air quality continuously.

Energy Efficiency: Since, the air quality in Delhi may remain poor for longer periods and air purifiers may have to run for longer periods. So choose energy efficient purifiers so that power consumption is less.
