AllerAir Air Purifier 5000 Exec Copper

very good!

There are good general purpose filters out there that are much less expensive and will give you clean air, but that's not really what this is for.I moved into a new place a while back, and the previous owner had a dog, a fireplace, smoked in the house, and had new carpet in 1 room, and old WOW-musty carpet in another.He also apparently didn't like to take out the garbage, because the whole place smelled like month old cooking trash.I vacuumed, steam cleaned, painted, scrubbed, vacuumed some more, but the odors always came back. It was also ant infested, and I needed to fume the place more than once.I keep reptile pets, so it's a HUGE inconvenience to fume the place, as they all have to get moved out to fume.Also, there was a major water leak, and whenever you ran the A/C, it was obvious there was mold in the vents.It took a long time, but I'm running this on low speed 24/7 in my living room, and it keeps the place liveable while I slowly got the smells under control with cleaning. It does wonders on cooking odors, pet odors, staleness, mustyness, "wet dog" and some things that HEPA filters won't touch, like living next to the wastewater treatment plant.Sounds lovely, doesn't it?It works, that's all there is to it.I don't give things 5 stars unless they exceed any and all expectations.This met my expectations. I also wish there was a 'kit' to add powerful UV and photocatalytic elements to this unit, but I think it's not an upgrade, just an option on a new unit.This isn't for active cigarette smoke, but to help old odors to go away.
