Why You Need an Air Purifier

Household dust is well known phenomena to anyone who has done any vacuum cleaning, particularly if you have had the misfortune to have to change the bag. It contains living microorganisms, human skin cells, dirt, hair, pet dander and lots of other things that I don’t want in my lungs. One way to lose the gunk in the air is to get an air purifier.

What is a Air Purifier?

Air purifier remove particulates, gases or vapours from the air. They have a number of very clever mechanisms but the most common form for the household is a fan which forces air through a filter, arresting particulates at the surface of the filter.

Why Should I Get a Air Purifier?

  • Can remove pathogens and microbial spores from the air meaning that they don’t end up in your lungs
  • Air Filter can remove allergens like pollen, dust mites, pet dander and mold spores from the air leading to reduced allergy responses
  • Removes second hand smoke from the air making the environment less irritating
  • Less dust in the air will lead to less dust on your surfaces and electronics, especially DSLR cameras which are particularly sensitive to dust.

How to Choose a Air Purifier

The difference between air purifiers is primarily dependent on the smallness of particle that you want to arrest and has been standardised by the Institute of Environmental Sciences and Technology (IEST). The cheaper ones are towards the largest (5 microns), the more expensive towards the smallest (0.3 microns). Other factors are fan speed, method of activation, design, and stacking of different filters with different functions.

Air purifier machines will last for years though with some the filters will have to be replaced regularly. It is a great investment for a home especially if you unfortunate enough to have allergies.
