Jafända 3800 sq ft Smart Air Purifier, APP & Alexa, H13 HEPA & Activated Carbon Filters, Air Cleaner Remove Dust Pollen Smoke Allergies Mold Odors Pet Dander VOCs for Home & Office

Purchased this about 2 months ago. What I noticed immediately was that when it arrived it was packaged in a very sturdy box. Inside it was well insulated from the possibility of being damaged on the way to me. This was very easy to assemble. Before I even turned it on what I noticed was how easy it was to move around. Having wheels is a feature that my wife and I really like. We have another purifier that does not have any wheels and is heavier and difficult to move. I like the fact that is has temperature, humidity, and PM2.5 readings. Another benefit is that it has 5 fan speeds to choose from. Even on the higher speeds it is not that loud. On the lower speeds it is extremely quiet. On the higher speeds it cleans up the air fast! I know that it is working since we have an air quality meter and have done many before and after tests. Having a light that indicates when the filter should be changed is nice too.Only additional thing I wish this had, is a fan speed in-between the second and third fan speed.Great product.

as shown in the pictures, this unit has its work ahead of it — the space it’s in is very large — 22′ ceilings and an adjoining 20′ hallway not shown going past the stairway — maybe should have the JF999 but there were only so many coins in the Piggy Bank — on automatic, it doesn’t pull much air from the higher areas, but on level 4 and 5 you can see all of the particles in the air from all directions floating toward the Purifier — the noise level on 3,4 and 5 is about the same as the noise from our furnace returns and outlets there is a distinct difference in the amount of air circulation using all 5 levels — in the morning the sun comes through the windows above the Microwave which is the way we can see the particles in the sunbeams — it’s like watching Lemmings following their leader to be trapped in the filters — unbelievable how much dust comes out of a tissue box when you pull a tissue out — the air was clean when I came home from church today and just walking around on the hardwood floors kicked up a lot of dust — couldn’t be easier to change the filters with the magnetic catches on the panels — there are no gaps around the filters so all of the air has to pass a filter — the pre-filter is a very fine mesh durable enough to hold up when vacuuming — when the filter is shaken you can hear the loose carbon pellets shaking around in their small cavities — the controls are easy to figure out and the app works flawlessly — don’t have a grasp yet on what the particle readings are trying to me — is the # related to the particle size or the density of the particles — haven’t had the speed change during the Auto cycle — the highest 2.5 reading so far that I noticed is 8 then I increase the speed and it goes down to 1 quickly — only reason I can think of to not get this is if you believe a UV light or Ion Generator exposed to the air for a quick second would be of any benefit I don’t think it would myself — I ordered a set of Odor Filters and installed 1 each of the included filter and Odor Filter — the Odor filter facing the kitchen — don’t know how efficient that is but my brain said give it a try — my brain is more reluctant to put this in the Bathroom as my wife suggested — don’t think I want those particles inside this unit — the Odor Filters are noticeably heavier and have a gold band around the edges — originals are silver — I think the fit and finish of this unit is worth the premium price and am not sorry I ordered it

Well packaged, easy setup, very very quiet, moves a lot of air, looks great, impressive controls with status of air, temperature, humidity. Setup Wi-Fi and shared control with my wife, makes it easy and convenient to make changes. I hope to be enjoying this Air Purifier for a long time.

The media could not be loaded.  I have been buying air purifiers for years. Orecks that were too small. Honeywell that did not provide their own best filter designs just to name a couple. I finally decided to do some research based on my needs. Very large two story home with dogs. We both have allergies and problems breathing while sleeping. I compared the largest and best air purifiers and air scrubbers for large homes. I was trying to fine the best machine for the money and that could do the job without a lot of expense over a long period of time. I am tired of buying machines and replacing them. I compared the JF999 features, reviews from people who have the machine, and YouTube Videos against other popular name brand machines. Depending on the specs, the written reviews and comparisons on YouTube I found this machine to be the best option on the market. I have had on plugged outside my bedroom on the lower level of the house and one on the upstairs level. Yes, I got the biggest and best the company had to offer. I can run both machines on Auto or about medium and they are working sufficiently. The air on both levels of my home is crisp and clear. A couple days ago some grease overflowed in my oven while I was using it. When I opened the oven smoke Poured out and filled the Kitchen. My husband called me to tell me that something is going on with the air purifier down the hall. I asked what? He said the light on the front changed to red, is something wrong with it. I was excited about that. The machine’s seniors had picked up the smoke from by kitchen and indicated that the air was bad while it cleaned it up. Within 10 to 20 minutes all the air was clear and clean again. I am surprised that the machine picked up on the smoke all the way in the kitchen and cleaned it up without me moving the machine closer.I also notice that when I leave my home and go to other public places indoors. My nose can tell the difference in the air I’m breathing. It made me feel like I needed to start wearing my mass again when I leave my home. I am sleeping better and feeling emotionally healthy not dreading breathing in dust and musky air. The quality of air in my home is so much better now. By the way, I do not work for Jafanda or Amazon. I just wanted people to know that I support buying from this company. You can try it, and if you don’t like it or it’s not doing the job that I described you can send it back for free. I had never heard of this company before and I usually stick to Dyson, Honeywell, Oreck. This is the best air purifier that I have found on the market. Also, I won’t need new filters for a very long time. You vacuum the filters when needed, the machine also has a feature to let you know when you need to either vacuum the filter or replace them. There are several other feathers on this that I have not even used yet.It even has a room temperature and humidity. At this price point there is nothing better out there.

This is my first review after a first month of use. There are so many factors affecting the sustained cleanliness of the air inside. Also, it is well known that the air inside of a typical home is more contaminated than outside air. I have a 1800 Sq.Ft home. We also have a wood burning stove in the middle of our great room. We use fire to heat our home. On initial start-up the AQ count showed about 480. Shortly after startup it went down to 150-200 range. Then it fluctuated as high as 300 depending on what was happening in the house like some smoke coming out of the stove. (Square foot rating of the equipment applies only to “air exchange or circulation rate”.)We purchased a second unit and we have them both running on opposiing walls. Together they maintain very good “green” AQ at night when we are sleeping and there’s no activity in the house. During the day time and wood burning and other activities, they maintain from about AQ reading of 50 to 125. Yellow to lower speed Red.The reduction in smoke and dust stickinng on glass, mirrors, and flat surface throughout the house is very noticeable. Should be the same for our lungs. From this, we can guess how much cleaner the air is inside of our home.I will edit this once I had a year or two of good stable use. Thanks for a nice air purifier. Very attractive design and easy operation and maintenance.
