Review on 🔄 Vornado AQS 15 PreSorb Filter Replacements, Pack of 4 by Bryan Gilliam

I liked the Vornado filtration system so much I bought 3 of them and 5 boxes of PreSorb filters and 3 spare HEPA filters. I'm lucky that Revain also sells replacement Hepa and PreSorb filters as the Vornado AQS 15 is almost impossible to replace. The fact that Revain sells it reassures me that I can find replacement filters. It reduces the amount of dust in my house and I'm noticing a difference. I have all three devices running 24/7 in different parts of my house. It is easy to use, check if the dust filter is white and replace it. This saves the cost of replacing an expensive HEPA filter.
