In the comment section, I asked if anyone would be interested in a comparison of surgical masks being sold locally.
Here is that comparison. These tests are extremely rudimentary.
I am not a health profesisonal or scientist. But it will at least give you an idea of what to expect if you're ordering masks online.

Per the DOH, at this moment, not everyone needs to wear a mask. But those who have respiratory infections should wear a mask to avoid infecting other people.
Also those with low immune systems might want to wear a mask, especially when they're in crowded places. The only way you can be sure about the quality of a mask is by purchasing from those reputable brands who've gone through official testing.

As much as possible, you want to buy direct. For example, Indoplas have an official shop on Lazada and Single passenger rule edsa.
Alternatively you'd look for a reputable outlet like Mercury or Watsons. Finally there are some reputable medical outlet shops, especially in Manila City. If you buy from a random seller online or in the streets, there's a risk that you'll be given substandard single passenger rule edsa "fake" masks.
I have seen people advertising a certain mask but then delivering a lesser quality single passenger rule edsa. Or worse, putting a substandard mask in the box of a better quality mask.
