I am not sure about you but I'm having a hard time breathing lately whenever I'm outside. And I'm pretty sure that's due to the bad quality of air and of course the haze. This year, the haze is back so much earlier than the year before, usually it only kicks in end of the year but now even by March itself, we are feeling the haze. So the air purifier has been my best friend lately, I'll have it on whenever I'm at home so to make sure that I have cleaner and fresher air in the house, giving my lungs a break from the polluted air outside.
Here are some tips and things that you need to consider when buying an air purifier ;)
Things to Consider When Buying an Air Purifier
1. Area of coverage
It's easy to understand. The larger the area of coverage the better it is and the area of coverage is usually calculated in meter square "m2". But the information printed on the brochure, flyer or on the air purifier it's self is only the SUGGESTED area of coverage by the manufacturer. So what's the ACTUAL area of coverage ? The real and actual area of coverage is....
Also the larger the area the bigger the fan and generally lower noise from it too, as you can set the speed of fan to lower levels.
2. HEPA Filter
The high quality HEPA filter should generally filter out most particles from 0, 0.1 microns to 0.3 microns. So basically the smaller the number microns they can filter the better. HEPA filter's efficiency is usually 99.7% effective in filtering out particles.
3. Maintenance Cost
If you think getting an air purifier is just a one time thing, then you're wrong. The filters need to be changed every 6 months to 3 years, and some filter types are very expensive. So do put the cost of changing filters into consideration too when you are buying an air purifier.
Other Fun TechThere are many new air purifier technologies and terminologies that most brands come up with which sound really cool and fun but to be honest, they have mild to little effect to overall air quality. And these are the common ones that you'll come across with :
Charcoal - Charcoal filter may help in reducing odors and some gases but you need to have a lot of it. What I'm talking about is 1 to 3 kgs to make a real difference.
Ionizer/Plasma Cluster/Nano Ion - This may make the air smell and feel fresher and also generally helps dust to stick to each other and not float around, but it may produce ozone gas which is sort of bad for you in a large concentrations. As for the ability in killing bacteria, there have been no independent studies done other those from the manufacturers so we really do not know if it's effective.
UV Light - It's suppose to kill bacteria and viruses but again no real study done other than those from the manufacturers.
Haze Mode - It'll just make the speed of the fan faster and reduces it in cycles.
Smoke,Odor or Dust Detector - Again, it just makes the fan speed faster when it detects something that smells. Good for farts ! Seriously, no joke, it changes color whenever it detects fresh farts in the room. ;P
Humidifier - Would be useful in dry locations but not necessary.
Anyway, as long as you understand the 3 main points (Air of Coverage, HEPA Filer & Maintenance Cost), you will generally be getting a good air purifier unit. :)
