Review on 🌬️ Medify MA-40 Air Purifier with True HEPA H13 Filter - 840 sq ft Coverage for Allergens, Smoke, Dust, Odors, Pollen, Pet Dander - Quiet 99.9% Removal Down to 0.1 Microns - White (1-Pack) by Holly Haman

While this is a very good air purifier and the HEPA13 filtration combined with the ionizer is really good, I was very disappointed that it lacked essential features. actual product shipped! After my daughter bought this item, I bought it directly from the link in her order history because I loved the features. Your product version and even the video review on Revain's product page shows the following features that were missing from the version I received: 1. Air quality sensor2. Photo sensor for night detection3. Auto Mode I am very disappointed that the manufacturer is removing these important features without notifying the customer or changing the model number in any way. The product I received had the air quality sensor and photo sensor removed and replaced the auto mode with a sleep button. People buy products based on review videos and that was a pretty blatant misrepresentation. Don't get me wrong, the other features are good and I think the noise levels were pretty good. But I really bet on the automatic mode of the air quality sensor. This is the feature that put it in first place compared to the top rated BluAir 211+. I would have opted for the 360-degree round filter on the BluAir 211+ if I had known that the air quality sensor in auto mode and the photo sensor were removed on this product. They even changed the user manual and removed the air quality maintenance section on page 14. I have to admit that I get really frustrated when I buy something that I think has certain features, only to find out that the manufacturer just decided to remove them without instructions. in the product link. It doesn't matter if competing products don't necessarily offer removed features. That's the business principle. Sorry Medifi. You should get bad grades for that, and it's not like you make bad products. Please create a new version of the model name when changing button functions! Call it MA-40LE or something like that to indicate the limited edition. If my daughter actually has the 1.0 version and I buy from her order history and get the lower 2.0 version, that's no good.
