All particulates gone

The filters in the facility could use more like these. I know they boast about finding out 99.99999 % of particulates, could be close to 100%.

Went to home depot earlier to buy these and noticed the poor construction of the hdx brand. Put them back on shelf and came to Walmart. Much better quality.
