Factors to keep in mind while buying

Size Of The Room

Depending on the size of the room, air purifier sizes will differ greatly. Ideally, the air purifier must be placed 5 to 10 feet away from where the person usually sits. The outflow should be directed towards the direction of where the person sits. It’s all about getting the right balance in the airflow.

Presence Of Allergies

If somebody in the home has a risk of an allergy, or if there is a smoker within the home, then the HEPA filter must be accompanied with a carbon filter to clear out the microscopic pollutants.

Also, with this point comes the ease of cleaning or replacing the filters. Filters can be either washable or replaceable, and if spare parts for air purifiers are hard to come by, then the natural choice would be to settle for an air purifier with a washable filter – as is the case with some old vacuum cleaners.

Additional Features

Some air purifiers come with added functionalities such as the ability to reduce the presence of unpleasant odours in the air. While this might seem as a promising feature, it might just be a gimmicky feature which seldom works, and instead emits ozone into the air.

Besides this, some air purifiers come with remote controls for easy controlling. Needless to say, this is a handy addition.

The Benefits Of Buying An Air Purifier

• Air purifiers improves the quality of air within homes and offices to maintain a pollution-free environment.
• The walls we use to shelter and protect us from the elements also trap airborne chemicals, gases, odor and particles. The EPA has found that our dwellings may contain air that is 2 to 5 times, even 100 times more polluted than outdoor air.
• Many researchers now believe that disease is an on-going process in the body that may take years to evolve from the earliest stage. Therefore a fetus or newborn exposed to a cancer-causing toxin early-on will have an increased chance of developing a disease later in life - simply because it will have more time to evolve.
• Natural circadian rhythms and sleep cycles have shown to improve when the air quality is better. This trend actually goes with smart scales being able to measure the air quality.

Air purifiers will get smarter. The best example in this regard is the Mi Air Purifier by Xiaomi, which purifies the air and integrates with a smartphone app to notify the user about the status of the contaminants at home.
