Important Points Considering while buying Best air purifier for home use in 2020.


1.Air purifier filter?

      1.1 High-Efficiency Particulate Air Filter (HEPA).

  •  You can find HEPA filters in most air purifiers bcoz of its popularity. These are small, portable units that may work for a single room.  
  • The best room for a unit is the one where you spend most of your time usually your bedroom. 
  • Some people say allergy symptoms improve after using these type of air purifier. It does not remove it, it stops from growing more.
  •  It removes at least 99.97% of 0.3-micrometre particles. HEPA filter all the air going into a clean room must be arranged so that no air bypasses the HEPA filter. It does not generate ozone or harmful byproducts.

      1.2 Working:


  • A HEPA filter is a type of mechanical air filter, it works by forcing air through a fine web-like network that traps harmful particles such as pollen, pet dander, dust mites, and smoke.
  • It acts like a strainer where particles smaller than the largest opening can pass through is incorrect and impractical. Unlike membrane filters at this pore size, where particles as wide as the largest opening or distance between fibres can not pass in between them at all, HEPA filters are designed to target much smaller pollutants and particles.
  • These particles are trapped through a combination of the following three mechanisms:


  • A mechanism that is a result of the collision with gas molecules by the smallest particles, below 0.1 μm in diameter, which are thereby slow down and delayed in their path through the filter; this effect is similar to Brownian motion and increases the probability that a particle will be stopped by either interception or impaction; this mechanism becomes dominant at lower air flow.


  • Particles following a line of flow in the air stream come within one radius of a fiber and adhere to it.


  • Larger particles are unable to avoid fibers by following the curving contours of the air stream and are forced to embed in one of them directly; this effect increases with diminishing fiber separation and higher airflow velocity.

2.Clean air delivery rate (CADR).

CADR Rating measures an air cleaner’s effectiveness based on your room space and the volume of clean air produced per minute. This shows how well dust, pollen and smoke are removed from the air in your room.

For example, an air purifier with CADR rating of 300 cfm (cubic feet per minute) will clean a room of 300 sq ft much faster than an air purifier with CADR rating of only 200 cfm.

3.Air Changes per Hour (ACH).

An air purifier with ACH rating indicates how many times per hour it can exchange the air within a room. It shows exactly the power of an air purifier fan. In short, a 5X ACH rating air purifier will clean the specific size more times than a 2X ACH rating air purifier. 

If an air purifier has 6 ACH rating, then it means that it can purify a room 6 times within an hour. For people with lung issues, ACH has to be at least 4 or more. Normally, 6 or 8 is the most preferred choice.

4.Power Consumption.

To Calculate the Power consumption of an air purifier.

 Watts = Volts x amps.

Watts x hours / 1000. The resultant is the power consumed by an air purifier per day.

Mostly an air purifier in India consumes 50 Watts to 200 Watt.
