I really debated on buying this because it’s so expensive. I read all the reviews and despite some negatives ones I decided to try it out. I’m really happy I did. This thing got me through the San Diego heat wave (no AC) and last winter I used it almost every morning. I love that it is 2 in 1 because I have a small apartment and the design is nice. I’ve had it for a year and I haven’t needed to replace the filter yet (it came with an extra). Five stars!!
