Review on TREDY 4 Stage Purifier TD 1500 Replacement by Jim Agosta

Have tried and used other air purifiers but this one is more trustworthy. It shows you the cleanliness of the air along with a very good strong exhaust air flow. The inner part that the filter connects to is made of metal, not plastic. This filter (bought to replace the one that came with the kit) is very well made and it's easy to see that it's better than other filters I've seen. The Tredy block itself works very well, is easy to use and the filter is larger than the last one I returned. Easy access for maintenance and filter changes. This one is a guard. Thank you Tredi!
