This is a lifesaver!!!

Allergy season was super bad this year, especially with my dog tracking things in the house and the smoke from wildfires. My doctor recommended that I get one of these so I got the Puro because it had the strongest filter I could find. Within an hour I could already feel my sinuses beginning to open up. I slept through the night without coughing and have been sleeping SO much better now that this is running in my bedroom. It is SHOCKING to see just how much dust, dander, pollen and junk is in the air in my house! It’s so gross. I can’t believe I was breathing all of that into my lungs! This is literally the best thing I’ve bought on Amazon in years, which is saying a lot. If you have allergies, this thing will make your life so much better. I am obsessed!

Made a big difference in our air (and odors)

Overall I am VERY pleased with this filter...the features and the the function of it. To top it all, this is a chic, handsome machine. Really happy with it!

I stopped taking my allergy pills

After much research, I decided to purchase this product in a last ditch attempt to control my allergies. I’ve lived in the south almost all of my life, but I have struggled the last year with year-round allergies to the point I’ve considered relocating. I appreciate the advanced HEPA 14 filter, and have put this unit in my bedroom. No more coughing or sneezing, which is a real blessing!

Easy and works great

If you're the type of person to pour over reviews and really do your research, this is the purifier for you. Easy to use and clean. Within 2 hours of running this in the main area of the house, my husband's allergy attacks stopped. It helped so much that we moved it to the bedroom. If you're a very light sleeper, this will keep you up - in sleep mode it's quieter than my husband's CPAP machine though ? Blowing out the filter once a week really helps, and accessing the filter is a breeze. Also easy to wipe down the inside. Attached photo is the filter after 1 week of use (construction going on in home). Also great to run in the kitchen if you're cooking something strong smelling (fish) or cutting onions, will prevent smell from traveling in the home. We'll be buying another one of these to keep running in the living room while we keep this unit in the bedroom. Worth the investment!
