Now the question was, how to buy an air purifier? I had zero knowledge about this machine. One of the most strenuous thing I found with buying air purifiers is the imponderable amount of choice….

This is a machine used to evacuate airborne pollutants from the air. Available to lessen asthma and allergy symptoms. Air filter is also beneficial to reduce cigarette smoke. There are different types of air purifiers available in the market. Each Model has its own advantages and usage for specific purposes.

This step is very important before buying the filter. Since this will help in gaining a proper purification outcome.

Certain Parameters To Consider

  • Know the Filter efficiency: This efficiency depends on the performance of an air purifier. Airborne and allergen particles usually measure in the size range (0.3 microns – 5 microns). Most of the air particles are capable to to eliminate particles that are as small as 0.3 microns or larger.
  • Clean Air Delivery Rate: This is the second parameter. Which measures the total mass of air that a purifier is able to cleanse of one particular pollutant per hour.
  • Operating Noise Level: This is an important factor. When your machine is running, Its operating noise may sometimes become a problem or disturb your activities. In such cases, you can opt for some quite air purifier having a minimum sound decibel.
