Purchased this item about a month ago. I've noticed a big difference in air quality, ability to add fragrance is really nice feature, noticed less sinus problems, less dust, very quiet and easy to operate.
I bought this unit last year. I have been pleased with how it has worked for my allergies, however, this morning the fan stopped working. I called support, but I'm 11 days out of warranty, so they will not replace. And of course you can't but a replacement part to fix it either. Probably better off going with a less expensive unit that is easier, financially, to replace.
I bought this about 2-3 weeks ago and this has improved my air quality tremendously!! I live in a shared home and my roommates feel the exact same. I WILL BE PURCHASING ANOTHER !!
I bought this filter about a month ago and I am so glad I did. Anytime the winds start to pick up outside, I inevitably get a sinus headache. This air purifyer has been so helpful with helping me avoid any sinus headaches I even purchased another one for my work office.
