Room Size – Home air purifiers are designed to serve a particular size of area & any space bigger than that would not serve the purpose. If your room is cleaned regularly with HEPA filter vacuum cleaners than you can go for a bit smaller air purifier than actually recommended. But if you have pets & kids who often play outside, then you must follow recommendations at all costs.

Air Flow – The air flow of a purifier is the amount of air which is processed by the device. This is measured in cubic feet per minute (CFM). This measure can range from 100 to 500 CFM. It is to keep in mind that large air flow would demand more pressure drop on filters & hence would need more energy & more noise.

Noise Levels – These range from 30 to 55 decibel. The passive airflow purifiers are quieter but the air flow in this mode is rather limited & hence would consume a lot of time before it cleanses the entire room. So what you need is a range in your purifier which starts from quiet enough that it can be placed in a room where kids are sleeping & fast enough that it can clean the entire room in the matter of minutes.

Air Filtration Levels – Probably the most important feature. This is the reason why are you buying an air purifier at the first place. Air purifiers offer a combination of several filters in order to achieve the desired levels of filtration. A perfect combination of filters can prolong the life of air purifier & hence would ensure a longer duration of clean air. Various filters offered are :

  1. Mechanical Pre-Filters – These filters are also called first stage filter as they trap large particles and hence prolong the life of the inner filters. These filters could be easily washed with water hence maintenance cost is really less.
  1. Charcoal Filters – This one removes pollutants on the molecular level & is very efficient in removing pet odors and dangerous gases. However, these can’t be washed & needs to be replaced from time to time.
  1. Hepa Grade Filters – These filters come in various forms but the standard filter has the ability to remove 99.97% of particles which are 0.3 micrometer in size. These can be washable also depending on which one you are choosing.
