Top Air Filters for Under RMB 1,000: Dr Richard’s Self-Tests Show Cheap Models Do Well Too

Following his in-depth tests on the best pollution masks last year, Beijing-based physician, blogger, and obsessive air filtration tester Dr Richard St Cyr has recently been on the hunt for budget air filters to help us Beijingers fight off the filth that regularly assaults our breathing passages.

Today he posts his results from rigorous home testing on his blog My Health Beijing, demonstrating that at least in enclosed environments smaller than 40 square meters (such as his office and bedroom, where he conducted tests), low-priced machines can do as well as the top-of-the-line models.

His criteria for choice were:

Priced under RMB 1,000
Preference for well-known international brand names over Chinese models
HEPA-rated filter (or close to it)
Fan strength
Rated for at least 21 cubic meters

And if you’re still unconvinced of the damage such particulates can cause to your health and wellbeing then you might want to watch this.
