Factors to Remember Before Buying a Purifier

Getting a purifier is no big deal as all you have to do is shell out money, but getting a reliable one needs some background work. It’s ideal to satisfy these requirements before choosing a purifier for your purpose.

  • Filter: This is extremely important as it holds the top place in filtering out unwanted particles serving your goals. Ensure that your device has a high-efficiency particulate air (HEPA) filter (physical filter), which is recommended by the American Lung Association itself as this traps 99.97% of particles that are 0.3 microns or more prominent. Choose a model that boasts of using a HEPA filter.
  • Some also have additional filters that trap gases, PM 10, pet dander, and other compounds helping you resolve air quality if your family members smoke or you have a pet. Pick a purifier that has optimal activated carbon. Some others specify that they use ionizers or UV light for filtration, which is not much useful.
  • CADR Rating: Clean air delivery rate (CADR) is what helps individuals pick an excellent air purifier as it conveys the effectiveness of a purifier is doing its intended purpose. It is the volume of purified air that could be expected from your device in an hour. Higher numbers indicate more significant efficiency.
  • Size of the Room: This is yet another essential point to keep in mind as buying a small filter for a considerable room would be a waste of money. Analyze your room size and figure mow much space you would want for your purifier to do its job. You can do this by checking the ‘air changes per hour’ that are available in the specification list. The higher the number better is performance.

Other Factors to Keep in Mind for Better Air Purity

It is better to maintain air quality by following the points given below:

  • Limit or quit smoking
  • Ensure that chemical factories or anything that emits pollutants are safely outside the city limits
  • Try carpooling and use public transportation to limit the release of pollutants into the atmosphere
