Shark Air Purifier 3-in-1, Nanoseal HEPA, Air Purifier, Purified Heat, Purifed Fan, 500 Sqft, HC452

This thing is great! It really warms a place up and keeps the air clean. Our cabin in the woods doesn’t have air or heat so we had been using space heaters all winter with the justification that we weren’t there enough to invest in central heat. We got this and our March bill was 1/2 of February even though they both were an average of 54 degrees. Definitely could be saving our power bill. It’s sure that the air is in terrible condition anytime food is being prepared or essential oils are being run, but I think that shows that the sensors really sense the air! I’m a little bummed because I paid $399 before tax, but then like 2 weeks later saw it for $299 also here on the Walmart page, then saw it for $315 so I’m scratching my head about that. I’m going to look up price adjustments. We did have it completely blink out on us and say our air quality was 0% like the first week we got it but so far no other errors.
