This air purifier is great. Has a steady white noise effect with various speeds while it purifies the air you breathe. We love it while we sleep as it makes the air fresh - no allergies at night anymore- and the calming sounds lulls us to sleep. Great product!
I recently purchased a PureZone Elite 4-In-1 True Hepa Air Purifier . . . What a difference it has made in my home!! It has been used in the living room, & master bedroom . . . Quiet, & does not take up a lot of space!! A much needed product for those who suffer from various allergies . . . Pure Enrichment, & their PureZone Elite Air Purifier does not disappoint!!
I just ordered a 4 in 1 air purifier. I am finding the 3rd speed is a little loud for me. I have it set on the 3rd speed right now to clean out the air in my apartment since this is the first time I have plugged the air purifier in. I will probably run it at the 2nd speed normally. So far, the noise level is the only thing I have an issue with.
Bought one last year and it cleared the air that helped my allergies so I bought 3 more for all our bedrooms. I also bought 3 more for my daughter's house. We all sleep better!
