This air purifier arrived well packaged. I also really like what is shown on the packaging. It shows two different types of filters that you can buy as soon as they become available. It was easy to unpack. You need to turn the device upside down, unscrew the bottom and remove the plastic from the filter. Put the filter back in place, turn the bottom back and you're good to go. As soon as you plug it in and turn it on, it will cycle through the 4 lights and then stop at the color of the air in your room. So I started in my daughter's room. We are cloth diapers and they can get quite smelly after a few days if we throw their pads and wipes in our Ubbi. which is kept in her room. Imagine, to my surprise (no), the air purifier would show up as red. Therefore, the colors related to air quality range from excellent to terrible blue, green, orange and red respectively. I checked it an hour after turning it on. As soon as I entered the room, the air became noticeably better and the light turned blue! During the week I took the air purifier to different rooms of the house. The other bedrooms were green, the bathrooms were orange-red (red is where we keep our daughter's dirty cloth diapers). All rooms were "vacated" in an hour or less. The big challenge was our open kitchen/dining/living area of approx. 625 sqm. ft. This air purifier is best suited for rooms up to 480 square feet. I installed it in my living room and it stayed green for most of the day. At the end of the day, it finally turned blue. I installed an air purifier in the kitchen while I was cooking and it worked, shutting off a bit to keep the air clean and usually floating orange/green until we were done. I love that it has a lock feature because my 2 year old loves pressing buttons and anything that lights up. Sleep mode is great. The fan spins down and the light is barely visible. I added a video about hibernation. I wish it had a handle to make it easier to move from room to room. If in the future they make a small one that stays on the bathroom sink like a 24 ounce bottle size I would definitely get one! Tip tip Renpho ;) I would also like to add that I have a Renpho scale and love it too! All information and calculations go straight to your phone app. All in all a very good product.
