It's a good start, but for VOCs and gases you'll need activated carbon. Those 2-in-1 filters do exist but cost more. And many are scams because they don't have enough volume of activated carbon.

Getting rid of the VOC source, if possible, is much easier than trying to filter it.

Any filter with a little bit of carbon added is going to be useless after a few days, or maybe even hours.

The only VOC filters that work have multiple pounds of carbon, with the good filters having upwards of 10-20 pounds. It also has to be replaced regularly.

My common winix air purifier has a replaceable carbon filter.

Why would they cut corners? Activated carbon isn’t expensive.
