Bests & Worsts Reviews from Amazon

I researched this product (all purifiers as a first time buyer of one) extensively before purchase and as a smoker which was my main motive and want of a purifier. Firstly as many others would and have recommended if a smoker, the smoker's filters make a huge difference (which I also ordered). When I received the Trueair, I ran it the majority of the time, I woke one morning and it simply didn't turn on at all...it was dead within 2 weeks time. I knew it wasn't my imagination that it was getting quieter and running much weaker for several days leading up to it dying out on me. I contacted customer service and they IMMEDIATELY reshipped a new Trueair to me (I was given the option of a full refund as well) but after so much research, I wanted to believe I simply received a malfunctioning product. (Simple instructions were sent to ship the faulty one back within 30 days and a promise of a return of shipping costs as well.) So take 2...I received the new Trueair within an impressive 48 hours and decided to utilize the original filters it comes with and did put the scent pack in this time as well. (I had noted others saying it wasn't a pleasant odor and being quite sensitive I opted against it the first time.) The previous product was definitely faulty from day one, the one I have now is very powerful and it runs 24/7, it does quite a decent job with the regular filters and I actually wish the scent pack was much stronger and lasted longer as I find it really quite pleasant. After 5 days with the regular filters, I switched back to the smoker's ones and did notice a definite decrease of cigarette smoke and odor. I really love the white noise it offers too, on low it can barely be heard and on high it sounds like a medium level fan but if I'm sitting directly beside it on the phone, it's certainly not too loud by any means...it's perfectly fine plus as said, I like the white noise of it. I could use maybe one more for the space I have it in (approximately a 300 square foot space) but it is a very powerful little machine and really does very well at purifying the air...I'm impressed! I am also extremely impressed with how the company handled the return and refund of shipping costs, all as promised and very prompt in all dealings. My only complaint overall is the cost. I'm in Canada (Amazon.ca doesn't carry it or the filters) so after conversions with the Truair and filters and shipping, this was a $150 expense so just be aware of this if outside of the U.S. and the filters will be hard to come by so do anticipate that you will need to order more filters only here. Nonetheless I plan to buy another for my current space and will definitely be buying one for my bedroom as well (a non-smoking zone with the door always closed but I love the fresh air feel and sound). So with 2 more, having 3 I wish the upkeep of filters was a bit easier and more affordable but it is actually worth it to me and the filters in my opinion, do actually last longer than stated. I would highly recommend this purchase (to my surprise and my only review of a product ever), do be realistic in the space you place it in and I feel very much at ease "should" anything go wrong in the future, I know now the warranty will absolutely be honoured too which is rare these days.
