[Other] [Tech With Furqaan Ep. 6] Air Purifiers: A Breath of Fresh Air!

Hey
Mi Fans,


It's weekend and it's time for another episode of Tech With Furqaan Series!!! In the last episode, we had a brief discussion on Power Banks. And I am pretty damn sure that you all loved it! So! Today's topic is Air Purifiers. I will throw some light on the detailed explanation of Air Purifiers.

Air Purifier, the word itself says it all! Something which purifies air, right? But do you know why it's named Air Purifier and not anything else? No idea? Don't worry! I will give you a brief explanation about Air Purifiers and I am sure after reading the whole thread you will earn a great amount of knowledge about Air Purifiers. So, without wasting much time let's jump into the world of Technology!!!!

Air Purifier, What's that?


An air purifier is a device which removes contaminants from the air in a room. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.

Tough to understand? OK let me tell you a simpler definition. An Air Purifier is a device which removes impurities from the air and cleans the air which is breathable. As simple as that!

How Air Purifier Works!


According to World Health Organisation, India is ranked among the world’s worst for its air pollution, with 13 out of 20 most polluted cities of the world in India alone. And due to the increasing level of pollution in the country, the number of deaths due to pulmonary and respiratory diseases is also shooting up significantly.  

Allergens like smoke, mould, pollen, bacteria, viruses, and pet dander can cause damage to the lungs and the immune system. These contaminants cannot be seen by the naked eye but can be filtered out by air purifiers.

Air filters use fine sieves that filter particles with air circulation. This filter exchanges the air in the room by using a fan to draw the air through the purifier. The impurities remain on the filter leaving pure air to continue on through the machine and re-enter the room. As air flows into the purifier, the finer the sieve is, the smaller the particles it can trap onto the filter. HEPA (High-Efficiency Particulate Air) air filters are made from very tiny glass fibres that are made into a tightly woven paper. They are guaranteed to trap 99.97% of airborne particles above 0.3 microns. The more times the air passes through the HEPA filter the cleaner the air will be.

Types of Air Purifier.


Ozone purifiers - Ozone is a reactive oxidant that can destroy some chemicals and bacteria. When it reacts with some substances in the air, those substances are broken down into materials that are pollutants.

Ionic air purifiers - This type of purifier works by ‘ionizing’ air, causing particles to gain either a positive or negative charge. The ionic air purifier has a collection of plates that contain an opposite charge from the air particles; therefore, the particles are attracted to the plates

Carbon air purifiers - This type of air purifier is very effective in capturing particular particles, including gas, smoke, and odour. It is also the most absorbent filter sold on the market.

Ultraviolet light air purifiers - The Ultraviolet light air purifier sterilises microorganisms as they pass through, including viruses, germs, bacteria and mould. After they are treated with the ultraviolet light, the micro-organisms are no longer able to reproduce and grow.

Some facts you must know about Air Purifiers!


  • Air purifiers will eliminate the need to ever dust again.

  • If you have allergies, air purifiers are a silver bullet and you will not have to do anything else.

  • If an air purifier has a HEPA filter in it, it must do a good job.

  • Air purifiers will take care of all odours in your home so you don’t have to bother with common housekeeping.

  • If you have allergies, you should never open your windows.

  • If you have dust mite allergies, the first thing you need to do is buy an air purifier.

  • It doesn’t matter what speed you run your air purifier — it’ll do a good job at any speed.

How to Select an Appropriate Air Purifier?


There are certain criteria to consider while purchasing an Air Purifier, some of them are listed below:

Performance - Look for a unit that removes a high amount of particles from the air, including smaller-sized pieces.

Air volume capacity - Choose a unit that is recommended for your size room. This is usually expressed as square feet.

Health Concerns - Consider what substances you want to be removed from the air: smoke, germs, bacteria, etc.

Ease of use - Make sure the unit is easy to operate, clean and change the filter

Noise Level - Is the unit considered ‘whisper quiet’? You can request its operating noise values before you make a purchase. Quieter units are around 35 decibels.

Manufacturer - Choose a purifier that has a reputable manufacturer. The Association of Home Appliance Manufacturers is a great source.

Indoor factors - If there is a particular pollutant affecting your health, look for a unit that works best at eliminating it.

Maintainance Cost -  Replacement filters do cost so make sure to look at the replacement interval and the cost of filters.

Quality - Make sure the warranty covers the internal parts of the unit.


Warranty - Look for a long-term and comprehensive warranty

Quick Look at the Mi Air Purifier 2!


Let's talk about the specifications of Mi Air Purifier 2.

Highlights of Mi Air Purifier 2:

  • Dual fan, air ducts for large indoor circulation
  • Produces nearly 10,000 litres of clean air per minute (310 m³/h)
  • 3-layered filter removes 99.99% of PM2.5 particles
  • Real-time air quality monitor and auto speed control
  • Smartphone remote control and alerts
  • Occupies area equivalent to an A4 sheet of paper

High-performance filters can't distribute clean air to the far corners of your home. That's where the dual fan, four air duct system comes in. Mi Air Purifier uses two high-performance fans to take in and expel air upwards through 4 independent air ducts. Clean air spirals up towards the ceiling, circulating 360° in all directions to fill the room before being drawn back into the purifier.

Mi Air Purifier uses an ultra-dense Toray PP and PET HEPA filter to trap PM2.5, PM0.3, pollen and other inhalable particles, allowing only clean air to pass through. It measures 7.7m when fully extended and effectively filters out 99% of PM0.3 particles and 99.99% of PM2.5 particles.
The Mi Air Purifier 2 is made with PET (polyethene terephthalate), the outer layer is 3 to 5 times tougher than comparable models. It has high flexural strength and is resistant to folding, grease, fats, acids, alkalis and most solvents. The cylindrical shape provides 360° filtrations of dust, hair and other larger floating particles.

The ultra-dense HEPA filter measures 7.7m when fully extended. Although ideal for air purification, this creates high air resistance. To get around this, considerable thought has been put into creating the folding process.

The filter design integrates three layers in one for easy replacement. When separated, each filter layer has its own lifespan and can be hard to tell when replacement is needed. Secondary contamination from dust may also occur when replacing filters separately. By integrating all 3 layers, Mi Air Purifier's cylindrical filter addresses these issues and keeps filter costs low.


Final Verdict!

The Mi Air Purifier 2 is one of the cheapest Air Purifier available at Rs 9,999 which can also be synced with the Mi Home app to monitor the PM2.5 particle levels at your place. The Mi Air Purifier promises a 310 cubic metre per hour of Clean air delivery rate (CADR) and can be synced with the WiFi in your house.

Also, Mi Air Purifier 2 quite effective when it came to bringing down PM2.5 particle levels, although in this kind of pollution the best reading you can expect is 250, which is still way beyond the permissible limit.

So, worried about air pollution? Don't worry just buy Mi Air Purifier for you and your loved ones from here.
