There are 3 filters to choose from. Don’t be confused because we’re here to help.
Today we will look briefly on 3 filter types and by the end of the article, you will be able to decide with confidence on which to get.
(The below guide is an excerpt from the Mi Air Purifier 2 review).
Filter Types
Blue Colour (Economic Version)
This version is an EPA (Efficiency Particulate Air) filter that’s able to trap particles that’re 0.3 microns in size. Essentially you can consider this as the standard default filter. This is the filter that’s mostly likely included in every Mi Air Purifier.
Green Colour (Formaldehyde/Enhanced Version)
The ‘specialty’ of this filter is that its designed to target Formaldehyde. According to the CDC, ‘Formaldehyde is a common chemical that can be emitted from a number of products in the home. Smoking, pressed wood, and particle board have all been shown to be sources of formaldehyde. Higher formaldehyde levels are usually found in newer homes or homes with new construction.’
On the Xiaomi website, this filter is advertised as a H11-grade HEPA filter that filters up to 99.3% of 0.3 microns. If we go by the EN1822 standard, you will see that this filter doesn’t meet the HEPA standard today. This is because the updated EN1822 standard has now categorized H11 as E11 making this filter EPA and not HEPA. Granted, this filter was released a while back in 2015 so the HEPA definition would have stood still then.
Purple Colour (Antibacterial Version)
This filter has an antibacterial layer can trap and kill dust mites. It’s able to trap 0.3 micron particles but it doesn’t mention whether its a EPA or HEPA filter.
Which should I get
The choice is simple; it’s either a HEPA filter or a non-HEPA filter.
Non-HEPA
If you aren’t fussy about filter grading, then you have 2 options; the Economic Version (Blue Colour) and the Antibacterial Version (Purple Colour). Get the Economic Version if you want a standard filter and Antibacterial Version if you want something that targets bacteria and dust mites. Both come with an activated carbon layer.
HEPA
If you want a HEPA filter, then the Formaldehyde/Enhanced Version (Green Colour) type is your choice. This filter also comes with an activated carbon layer. If you can get a HEPA filter, do get one. This is because a HEPA filter ranks the top when it comes to filtering minute particles.
