Thanks for the response. My company will reimburse me for respirator stuff but I didn't know that when I initially bought it so I'll have to see if they can do it without the receipt which is long gone. Did you mean this purple one? I was going to get these ones:

Would these be the best option for silica/floor dust?
The filter cartridges I got are these.
When I breathe in and out, I hear some rubber part moving due to suction right next to my nostrils. I am pretty sure the mask is working well because it was very dusty (removing bathroom drywall) and I didn't feel any irritation in my nose.
When the cartridges first arrived, I thought I needed to take the purple sticker off, but that was a no go. There are no holes underneath the sticker.
It is possible that the cartridges are there only to absorb fumes (in case of volatile substances) and there is an additional filter in 3M 7502 right next to the nose which does the main filtering. But I really want someone to confirm this speculation.
I'm not in London, but for really bad days up North, or for example if there is uanvoidable smoke from a building fire, I have 3M 7093B filters with a 3M 6500QL half-face mask. It's cheaper to order from Amazon USA rather than UK, and I got the mask itself from someone on eBay. I didn't want to get filters themselves from eBay due to fakes being commmon.
I selected the 7093B filters because they might not be affected [as much] by rain. Other filters can do different types of particulates & gasses - oil/hydrocarbon/organic vapour cartridges etc but they can get quite expensive.
Note that you can get different sized masks and fitting is recommended - I've seen people need to try 6+ different masks to get one that fits their face correctly & passes all the seal tests. Arco stores apparently do fitting.
