AirExtend HEPA Air Purifiers, Room Purifier with 3 Stage Filtration System, 24-Hour Timer, and 22dB Ultra-Quiet Sleep Mode, True Filter Removes 99.97% Dander, Smoke, Odor for Bedroom & Office

Read instruction card! A plastic bag encases the filter and must be removed before first use. Read manual too ; ) I'm Soooooo glad I got this air purifier! I recently restarted my keto diet and planned on adding Baked salmon, Brussel sprouts and Broccoli to my meal plan. Inside, in the oven. Those smells linger for Days and migrate upstairs!!! But before I could bake Those, I made a tbsp of popcorn in the micro, on sensor, and Burned it into a black blob, yay, less carbs! SKUNKED up the kitchen Big time! BINGO, two days after receiving this purifier I got to try it out. It cleared the smell out in less than an hour on Auto (before it lingered upstairs) (on Auto the fan speed cycles as needed until room air is filtered) Also, hours later, went to bed and forgot and left it running....it was so quiet I didn't hear it. That's where the timer woulda came in handy. Duh! Set it! It looks highend, very quiet, works Fantastic! I know no one reads manuals....the symbols on top of the machine are self explanatory. Easy to use! Measures 8-5/8" diam, 14-1/4" high, and weighs 6 pounds. Power supply is included. Great Buy! Awesome price!

This is a very quiet air purifier and I have recommended it to friends. I use it in my bedroom and run it every night and sometimes all day. I have done this for the past two months and it still works fine and has not had an impact on my electric bill. It does use a real HEPA filter. I like that it quantifies the amount of junk in the air. I’m not sure how accurate it is, but I appreciate it. My only complaint is that the controls on the top are not backlit. So it is difficult to see them in the dark especially because the top is black. You have to use a flashlight or have a nearby light on in order to see the options. This sort of sucks for me because I use it at night time. But I just leave it set on automatic. At least the power button is backlit all the time. Overall, this is a good air purifier and I would recommend it

I own three cats and suffer from allergies, and medication barely helps. My doctor made a few suggestions, like more frequent dusting and vacuuming and to consider an air filtration system with HEPA filtration. Looking through several different models they seemed bulky, ugly, noisy or just really expensive. Then I saw this AirExtend Purifier. It had a great overall rating, sleek look, and very reasonable price. Seemed a bit too good to be true, but I figured at that cost it was at least worth checking out. And I'm glad I did! It is fairly small so it was easy to find a place for it. I put right outside my bedroom to help reduce allergens while sleeping and reduce the morning mucous issues I was having. And it so quiet I can barely tell its on. It has a handy timer so I can set it to run for 6-8 hours while I sleep and not have to worry about shutting it off. The air quality started off in the mid 20's, and in a bit less than an hour it was down to 1. My mornings quickly involved a lot less nose blowing and coughing. This is a great purifier for this price, so much so that I bought one for my mother! Give it a try!

This air filter definitely is receptive to contaminants in the air. When someone is smoking or I'm cooking, it ramps up in response. Im not sure I notice a difference in the air quality but that may just be me. I like that it has different settings so you can have a constant fan or one that just senses when it's needed. I have had two for over a year and they still work like new.

Great buy!!! I recommend this air purifier bought it for my room as I am one who suffers from allergies plus I smoke indoors so it gets rid of the smoke smell, makes the air in the room feel fresh also I noticed I’m not sneezing as much. Easy to install literally just plug it in.. make sure to remove plastic on the filter first. Everything is touch screen..The purifier has 3 levels you can adjust and it isn’t even super loud. I pretty much leave it on 24/7 and haven’t had any issues. Great value for price also it looks stylish so it fits in with your decor. No cap no bs lol I recommend it guys!

This air purifier is awesome. I live in the country, which means alot of dust. The air purifier has significantly reduced the amount of dust floating in the air. I used to be able to see the dust floating in the air when the light would shine through the window. I no longer see any dust particles floating. My dusting has significantly decreased. I knew it was working like it should when I was cooking some bacon that got a little over cooked. It started speeding up the fan and I could see the numbers on the display start increasing. If I vacuum a rug nearby, then it starts speeding up the motor. The air purifier is quiet and easy to use. I keep the air purifier by our air conditioner intake.

I purchased this air purifier for my office and have been happy with it's performance over the past few months with regard to noise level and easy of operation. Strong filtering. Noise is audible, but still very quiet. After one day, using it in my room. I can smell natural smells. That was the best decision I've ever made! Within the first twenty minutes of me putting on the air purifier, I noticed a difference. After 2 hours, it was great! Highly recommended. Key positives: -Attractive shape which fits well on my desk -Simple to set up and start using -Air was fresher after only 2 hours
