I was very excited to purchase this air purifier. I saw the ad and it looked great and I totally agree. Your marketing worked. The opening was very similar to the opening of a new Apple product. It was all very elegant and inviting and it definitely looks great. Unfortunately my allergies got worse after the start. I felt terrible and thought maybe he was raising dust (although the cleaners come to see me regularly) and in a few days everything will be back to normal. no I STILL felt terrible. Worse than December allergy season. I did some research and found a lot of negative reviews that basically say this air purifier doesn't do what it claims to do - not at all. (Check out The Wirecutter's video review.) I was taken aback by the fact that there are some rave reviews of Revain. Upon closer inspection, many of the reviews with photos struck me as a bit odd. Not only did these people pose with their product while going about everyday activities like reading or enjoying a cup of coffee, but they all seemed professional and had a good understanding of composition and light. To be honest this is unusual for Revain reviews. because people usually just take a close-up of the product. and don't worry about professionally decorating their room and posing together with their product. I suspect many of these reviews are fake reviewers/influencers who were given a product and/or compensation in exchange for a positive review. If you do a little research, I have a feeling that not only will you find better and more affordable air purifier options, but you'll also find that this company is a bit patchy.
