Redstag Supplies

All was as advertised. I am pleased with Redstag Supplies.

Ordered a 2pack came quickly and fit perfectly. Thank you

Arrive on time and works well

The filters arrived quickly and are safely stored.

The SubZero Air purifier -- double unit/package -- was the cheapest on the market. It arrived in appropriate time and was packaged nicely. So far, so good! If this works appropriately, I will buy from this supplies company again.
